My “I Live for Summer” Facebook Frame

July 1, 2018 By Sherri

Many people ask me if I do better with heat or cold. Well, the truth is, I can’t tolerate either. Give me 65 to 75 degrees year ’round! I wish!

But I love Summer, because if I am in the water, I can actually enjoy the sunshine without passing out from the heat! And I NEED my sunshine!

The Silent Inflammation That Afflicts 3 Out of 4 Americans

carotenoids as natural astaxanthin

Story at-a-glance+

By Dr. Mercola – July 12, 2011

Scientists long ago discovered that a class of naturally occurring pigments called carotenoids held powerful antioxidant properties that are crucial for your health.

Carotenoids are the compounds in your foods that give you that vibrant cornucopia of color—from green grasses to red beets, to the spectacular yellows and oranges of bell peppers—as well as all of the beautiful flowers in your garden.

There are more than 700 naturally occurring carotenoids, but most people are familiar with only a few. Right now, you probably have about ten different carotenoids circulating through your bloodstream.

Only recently has one particular carotenoid jumped to the front of the line in terms of its status as a “supernutrient,” becoming the focus of a large and growing number of peer-reviewed scientific studies.

This carotenoid is called natural astaxanthin.

Synthetic (laboratory-made) astaxanthin is now commonly used worldwide to supplement fish feed lots in order to help them obtain the desired pinkish to orange-red color. You really should avoid synthetic astaxanthin because it’s made from petrochemicals.

Not only does natural astaxanthin carry potent antioxidant abilities, but as it turns out, it is also a powerful anti-inflammatory, which will be the focus of this article. Other carotenoids are easily obtainable through a good diet rich in fresh organic produce. However, this powerful carotenoid is harder to come by.

Astaxanthin Is in a League of Its Own

Astaxanthin is produced only by the microalgae Haematococcus pluvialis when its water supply dries up, forcing it to protect itself from ultraviolet radiation. It’s the algae’s survival mechanism—Astaxanthin serves as a “force field” to protect the algae from lack of nutrition and/or intense sunlight.

Astaxanthin is now thought to be the most powerful antioxidant found in nature.

There are only two main sources of astaxanthin—the microalgae that produce it, and the sea creatures that consume the algae (such as salmon, shellfish, and krill).Astaxanthin is now thought to be the most powerful antioxidant found in nature.

This pigment is the most commonly occurring red carotenoid in marine and aquatic animals and is what gives salmon their characteristic pink color. Astaxanthin is far more powerful than beta-carotene, alpha-tocopherol, lycopene and lutein, other members of its chemical family. It exhibits VERY STRONG free radical scavenging activity and helps protect your cells, organs, and body tissues from oxidative damage and inflammation.

What Makes Astaxanthin Special?

There are many properties that make this carotenoid unique. Here are the main differences:

  • Astaxanthin is by far the most powerful carotenoid antioxidant when it comes to free radical scavenging: astaxanthin is 65 times more powerful than vitamin C,1 54 times more powerful than beta-carotene, and 14 times more powerful than vitamin E.
  • Astaxanthin is far more effective than other carotenoids at “singlet oxygen quenching,” which is a particular type of oxidation. The damaging effects of sunlight and various organic materials are caused by this less-stable form of oxygen. Astaxanthin is 550 times more powerful than vitamin Eand 11 times more powerful than beta-carotene at neutralizing singlet oxygen.
  • Astaxanthin crosses the blood-brain barrier AND the blood-retinal barrier (beta carotene and lycopene do not), which brings antioxidant and anti-inflammatory protection to your eyes, brain and central nervous system and reducing your risk for cataracts, macular degeneration, blindness, dementia, and Alzheimer’s disease.
  • Astaxanthin is soluble in lipids, so it incorporates into cell membranes.
  • It’s a potent UVB absorber and reduces DNA damage.
  • It’s a very potent natural anti-inflammatory.

And how about some more great news?

There have been no adverse reactions found for people taking astaxanthin. Before I go into how astaxanthin works as an anti-inflammatory, let’s review what inflammation is and how it can cause devastating disease.

What You Need to Know About Inflammation

Inflammation is a necessary and important biological process that allows you to survive. It’s your body’s response to fighting infection and repairing damaged tissues—in other words, it’s part of your natural healing process. If you didn’t have inflammation, you’d never heal from any infection or injury.

When a foreign bacterium or virus enters your body, your inflammatory body kicks in to eliminate it. If you sprain your ankle, your inflammatory system activates to begin repairing damaged tissues.

There are five classic signs and symptoms of inflammation:

  1. Redness
  2. Pain
  3. Warmth
  4. Swelling
  5. Loss of function

Even sunburn is a sign of inflammation—when UV rays begin to damage your skin cells, the inflammatory “machine” turns on, making your skin red and warm. Mast cells are the key initiators of inflammation, activating potent “mediators.” The mediators attract white blood cells, and activate cells that produce additional mediators.

Mediators come in many forms, including:

  • Histamines
  • Tumor necrosis factor-alpha
  • Nitric oxide
  • Hydrogen peroxide
  • Interleukins
  • Prostaglandins (produced from arachidonic acid and the COX-1 and COX-2 enzymes)

Although having a red, swollen and painful sprained ankle is a clear sign you are experiencing inflammation, you may have an undercurrent of inflammation in your body and not even be aware. And silence can be deadly.

Chronic Inflammation: Silence Is Deadly

Inflammation comes and goes in your body as part of the normal healing process. However, prolonged inflammation can be devastating. Many people are experiencing ongoing, low-level inflammation without even knowing it—and this is a crucial factor behind chronic disease.

This systemic or “silent” inflammation is the evil twin of oxidation, and where you find one, you nearly always find the other. But this type of inflammation doesn’t cause you any pain—it lives “under the radar,” quietly lingering for years and even decades, where it silently injures your heart, brain, and immune system.

Left unchecked, systemic inflammation can lead to anything from asthma to rheumatoid arthritis to Alzheimer’s disease. In fact, the number of diseases linked to chronic inflammation is staggering:

  • Heart disease, atherosclerosis and stroke
  • Diabetes
  • Alzheimer’s disease
  • Parkinson’s disease
  • Multiple sclerosis
  • Rheumatoid arthritis
  • Ulcers, irritable bowel syndrome (IBS), and colon cancer
  • Allergies

There are many, many more. Unfortunately, Americans have the highest levels of silent inflammation in the world, with over 75 percent of people afflicted.

Why?

Two words: diet and lifestyle. Some of the largest contributors to chronic inflammation are smoking; a diet high in sugar, fried foods and trans fats; inadequate exercise; stress; and vitamin D deficiency. There are a couple of ways to measure how much inflammation is silently occurring in your body.

One blood test measures a substance called C-reactive protein (CRP), which might actually be a better predictor of your heart attack risk than lipids. Another test is called Sed Rate (or ESR for “erythrocyte sedimentation rate”), which is especially helpful in monitoring rheumatoid arthritis and other autoimmune diseases.

CRP is produced in your liver and coronary arteries, then released into your bloodstream when your body is fighting inflammation. In one study, natural astaxanthin was found to reduce CRP levels by 20 percent in just eight weeks. Another study found astaxanthin caused 43 percent of people with high CRP levels to drop into the average-risk range.

Clearly, this powerful agent has a remarkable ability to cool down the inflammatory process, thereby decreasing your body’s need to produce CRP.

By decreasing inflammation, astaxanthin can help prevent, and treat, a number of problems that result directly from inflammation, including rheumatoid arthritis, tennis elbow, carpal tunnel syndrome, and other repetitive stress injuries, which I will talk more about shortly.

Anti-Inflammatory Drugs Are Definitely NOT the Answer

Anti-inflammatories have earned a bad reputation. This is due to the fact that most of the compounds people commonly recognize as anti-inflammatories are DRUGS, rather than natural agents. Natural anti-inflammatories, on the other hand, can be very beneficial and lack the adverse side effects of anti-inflammatory drugs.

As a quick review, let’s review the truth about some anti-inflammatory drugs:

  • Aspirin can cause your stomach to bleed (acts on both COX-1 and COX-2)
  • Tylenol (acetaminophen) can damage your liver
  • Vioxx and Celebrex (non-steroidal anti-inflammatories, or NSAIDS) can cause heart problems (act strongly on COX-2 only)

In 1999, the New England Journal of Medicine stated that NSAIDS have caused as many deaths as AIDS. Vioxx alone has killed more than 60,000 people! I urge you to avoid these dangerous anti-inflammatory drugs since they have the potential to cause very serious side effects and even death. But astaxanthin is a different story and will not harm you.

Astaxanthin affects a wide range of mediators, but in a gentler, less concentrated manner and without the negative side effects. And it works for 4 out of 5 people. In one study,2 more than 80 percent of arthritis sufferers improved with astaxanthin.

Folks, that is four out of five people, that is impressive.

How Astaxanthin Tells Your Inflammation to ‘Chill’

A great deal of research has been done into how astaxanthin reduces inflammation. As is true for many antioxidants, its anti-inflammatory properties are related to its powerful antioxidant activity.

Astaxanthin suppresses a variety of inflammatory mediators—including tumor necrosis factor alpha, a major prostaglandin and a major interleukin, nitric oxide, COX-1 and COX-2 enzymes. It takes longer to produce effects than NSAIDS, but this means it doesn’t result in the dangerous side effects.

As G. Cole, UCLA Professor of Medicine and Neurology, reported to Newsweek Magazine in a Special Summer Issue in 2005 (pages 26-28):

“While anti-inflammatory drugs usually block a single target molecule and reduce its activity dramatically, natural anti-inflammatories gently tweak a broader range of inflammatory compounds. You’ll get greater safety and efficacy reducing five inflammatory mediators by 30 percent than by reducing one by 100 percent.”

So, what sorts of conditions can astaxanthin treat?

Astaxanthin May Help You Be an Athlete Extraordinaire or Weekend Warrior

The evidence is very positive for astaxanthin’s effects on a variety of inflammatory disorders. Let’s take a look at the human clinical studies related to four common inflammatory complaints: tennis elbow, carpal tunnel, rheumatoid arthritis, and exercise-related joint soreness.

    1. Tennis elbow (tendonitis): Caused by inflamed tendons, tennis elbow results in pain and decreased grip strength when gripping something with your hand.

A study by the Health Research and Studies Center involved giving tennis elbow sufferers an eight-week course of astaxanthin. The treatment group showed a 93 percent improvement in grip strength, as well as decreased pain.

    1. Carpal tunnel syndrome (CTS), aka “repetitive stress injury”: CTS is a debilitating disease of the wrist that manifests as numbness, pain, and even paralysis.

A study by the above group found eight weeks of astaxanthin supplementation resulted in significant pain reduction, both in terms of severity and duration, leaving researchers concluding that astaxanthin might be a viable alternative to surgery.

    1. Rheumatoid arthritis: RA is a painful and disfiguring autoimmune disorder.

After receiving astaxanthin for only eight weeks, RA sufferers showed a 35 percent improvement in pain levels, as well as a 40 percent improvement in their ability to perform daily activities. [Journal of the American College of Nutrition. 21(5):Oct, 2002.]

    1. Post-exercise joint soreness: Can astaxanthin be of benefit to you if you are healthy and have no disease or affliction?

In 2001, Dr. Andrew Fry of the University of Memphis studied the effects of astaxanthin on healthy people who trained with weights and who would typically experience exercise-induced joint soreness. He gave young male subjects astaxanthin for three weeks, while they performed strenuous workouts, and then evaluated them for knee pain.

The placebo group experienced post-training knee soreness, lasting up to 48 hours after their workouts. But the treatment group showed no increase whatsoever in knee joint soreness following workouts. [Fry, A. (2001) “Astaxanthin Clinical Trial for Delayed Onset Muscular Soreness.” Human Performance Laboratories, The University of Memphis, Report 1, August 16, 2001.]

So it appears that this amazing nutrient can help you, whether you are a top athlete or a weekend warrior, whether you have mild overuse symptoms or a major inflammatory illness—it truly seems to have benefits for anyone and everyone!

Make Sure Your Astaxanthin Is the Natural Variety from Marine Algae—NOT Synthetic

Some aquaculture companies are beginning to use natural astaxanthin instead of synthetic, even though it costs more, because it’s better for the health of the animals, and it’s far superior for pigmentation. Animals fed fish food with natural astaxanthin have higher survival rates, better growth rates, better immunity, fertility, and reproduction. Unfortunately, synthetic astaxanthin still dominates the farmed salmon industry worldwide.

If your salmon label does not read “wild” or “naturally colored,” you’re probably going to be eating a coloring agent somewhat closer to motor oil than antioxidant. Natural astaxanthin is more than 20 times more powerful as an antioxidant than synthetic astaxanthin.

Wild salmon are 400 percent higher in astaxanthin than farmed salmon, and 100 percent of their pigment is natural astaxanthin, rather than synthetic. Plus, wild salmon have much higher levels of omega-3 fatty acids than the farmed version.

But even if you are successful in purchasing genuine wild salmon, there is the problem with high levels of mercury and other unwanted toxins, not to mention the skyrocketing prices.

Final Recommendations

You may recognize the name astaxanthin because I have mentioned it in reference to krill oil, my favorite source of animal-based omega-3 fatty acids. One of the reasons I am such a fan of krill is that itnaturally contains astaxanthin. And our krill oil has the highest concentration of astaxanthin of any krill oil on the market today.

But, as high as it is, new research suggests you could enjoy even MORE benefits by further increasing your astaxanthin, even if you are already taking a krill oil supplement.

If you decide to give astaxanthin a try, I recommend with a dose of 8-10 mg per day. If you are on a krill oil supplement, take that into consideration; different krill products have different concentrations of astaxanthin, so check your label.

Advances in Understanding of Depression Offers New Hope

January 23, 2015 By Sherri

Story at-a-glance+

By Dr. Mercola

Depression is thought to affect about one in 10 Americans.1 In 2010, antidepressants were the second most commonly prescribed type of medication in the US,2 hinting at the severity of the problem.

Contrary to popular belief, depression is not likely caused by unbalanced brain chemicals; however there are a number of other biological factors that appear to be highly significant. Chronic inflammation is one. As noted in the featured article:3

“George Slavich, a clinical psychologist at the University of California in Los Angeles, has spent years studying depression, and has come to the conclusion that it has as much to do with the body as the mind.

‘I don’t even talk about it as a psychiatric condition anymore,’ he says. ‘It does involve psychology, but it also involves equal parts of biology and physical health.’

The basis of this new view is blindingly obvious once it is pointed out: everyone feels miserable when they are ill. That feeling of being too tired, bored and fed up to move off the sofa and get on with life is known among psychologists as sickness behaviour.

It happens for a good reason, helping us avoid doing more damage or spreading an infection any further. It also looks a lot like depression.”

One researcher even goes so far as to suggest depression should be rebranded as an infectious but non-contagious disease,4 while the author of the featured article playfully compares depression with an allergic reaction—in this case “an allergy to modern life”—considering the many environmental factors that are known to cause inflammation, from diet to toxic exposures and stress.

Scientists have also found that your mental health can be adversely impacted by factors such as vitamin D deficiency and/or unbalanced gut flora—both of which, incidentally, play a role in keeping inflammation in check, which is really what the remedy to depression is all about.

Inflammation and Depression

As discussed in an article by Dr. Kelly Brogan, depressive symptoms can be viewed as downstream manifestations of inflammation.

“The source itself may be singularly or multiply-focused as stress, dietary and toxic exposures, and infection… [I]nflammation appears to be a highly relevant determinant of depressive symptoms such as flat mood, slowed thinking, avoidance, alterations in perception, and metabolic changes,5” she writes.

Certain biomarkers, such as cytokines in your blood and inflammatory messengers like CRP, IL-1, IL-6, and TNF-alpha, show promise as potential new diagnostic tools, as they’re “predictive6 and linearly7 correlative” with depression.

For example, researchers have found8 that melancholic depression, bipolar disorder, and postpartum depression, are associated with elevated levels of cytokines in combination with decreased cortisol sensitivity (cortisol is both a stress hormone and a buffer against inflammation). As explained by Dr. Brogan:

“Once triggered in the body, these inflammatory agents transfer information to the nervous system, typically through stimulation of major nerves such as the vagus, which connects9 the gut and brain. Specialized cells called microglia in the brain represent the brain’s immune hubs and are activated in inflammatory states.

In activated microglia, an enzyme called IDO (indoleamine 2 3-dioxygenase) has been shown10 to direct tryptophan away from the production of serotonin and melatonin and towards the production of an NMDA agonist called quinolinic acid that may be responsible for symptoms of anxiety and agitation.

These are just some of the changes that may conspire to let your brain in on what your body may know is wrong.”

Using Brain Scans to Help Choose Treatment Type

Speaking of biomarkers, research11 by Dr. Helen Mayberg, a professor of psychiatry at Emory University, may also pave the way toward a more refined and customized treatment plan. Her research is discussed in the video above.

Dr. Mayberg has identified a biomarker in the brain that can be used to predict whether a depressed patient is a good candidate for medication, or might be better off with psychotherapy. As noted by the New York Times:12

“Patients who had low activity in a brain region called the anterior insula measured before treatment responded quite well to cognitive behavior therapy (CBT} but poorly to Lexapro; conversely, those with high activity in this region had an excellent response to Lexapro, but did poorly with CBT….

[T]he insula is centrally involved in the capacity for emotional self-awareness, cognitive control and decision making, all of which are impaired by depression. Perhaps cognitive behavior therapy has a more powerful effect than an antidepressant in patients with an underactive insula because it teaches patients to control their emotionally disturbing thoughts in a way that an antidepressant cannot.”

The Links Between Gut and Mental Health

A number of studies have confirmed that gastrointestinal inflammation specifically can play a critical role in the development of depression, suggesting that beneficial bacteria (probiotics) may be an important part of treatment. For example, a Hungarian scientific review13 published in 2011 made the following observations:

    1. Depression is often found alongside gastrointestinal inflammations and autoimmune diseases as well as with cardiovascular diseases, neurodegenerative diseases, type 2 diabetes and also cancer, in which chronic low-grade inflammation is a significant contributing factor.Thus researchers suggested “depression may be a neuropsychiatric manifestation of a chronic inflammatory syndrome.”
    2. An increasing number of clinical studies have shown that treating gastrointestinal inflammation with probiotics, vitamin B, vitamin D, may also improve depression symptoms and quality of life by attenuating pro-inflammatory stimuli to your brain.
    3. Research suggests the primary cause of inflammation may be dysfunction of the “gut-brain axis.”

Your gut is literally your second brain — created from the identical tissue as your brain during gestation — and contains higher levels of the neurotransmitter serotonin, which is associated with mood control.

It’s important to understand that your gut bacteria are an active and integrated part of serotonin regulation and actually produce more serotonin than your brain. Optimizing your gut flora is a key part of the equation to optimize your levels. If you consume loads of processed foods and sugars, your gut bacteria will be severely compromised because processed foods tend to decimate healthy microflora. This leaves a void that is filled by disease-causing bacteria and yeast and fungi that will promote inflammation and decrease the health of your second brain.

Low-Sugar Diet Is an Important Anti-Depressant Tool

Besides distorting your microflora, sugar also triggers a cascade of other chemical reactions in your body known to promote both chronic inflammation and depression. For starters, excessive sugar consumption leads to elevated insulin levels. That can have a detrimental impact on your mood and mental health by causing higher levels of glutamate to be secreted in your brain, which has been linked to agitation, depression, anger, anxiety, and panic attacks.

Sugar suppresses activity of a key growth hormone called BDNF (brain derived neurotrophic factor) which promotes healthy brain neurons. BDNF levels are critically low in both depression and schizophrenia, which animal models suggest might actually be causative.

Cultured and fermented foods, on the other hand, help reseed your gut with a wide variety of healthy bacteria that promote mental and physical health as long as your keep your sugar and processed food intake low. For instance, one 2011 study14found that the probiotic Lactobacillus rhamnosus has a marked effect on GABA levels in certain brain regions and lowers the stress-induced hormone corticosterone, resulting in reduced anxiety- and depression-related behavior.  So the three-prong dietary answer for treating depression is to:

  1. Severely limit sugars, especially fructose, as well as grains, as all forms of sugar feed pathogenic bacteria in your gut. The easiest way to do this is to avoid processed foods, and start cooking from scratch using whole ingredients. As a standard recommendation, I suggest limiting your daily fructose consumption from all sources to 25 grams per day or less.
  2. Avoid foods with genetically engineered ingredients, as they too have been implicated in the destruction of gut flora, along with promoting chronic inflammation. Keep in mind that conventionally-grown foods may also be contaminated with glyphosate, which has been found to selectively destroy beneficial, health-promoting gut bacteria, so ideally, you’ll want to make sure as much of your food as possible is organically grown to avoid pesticide exposure.
  3. Introduce fermented foods into your diet to rebalance your gut flora.

Beware that your gut bacteria are also very sensitive to and can be harmed by the following, all of which should be avoided:

Antibiotics, unless absolutely necessary (and when you do, make sure to reseed your gut with fermented foods and/or a probiotic supplement) Conventionally-raised meats and other animal products, as CAFO animals are routinely fed low-dose antibiotics, plus genetically engineered grains
Chlorinated and/or fluoridated water Antibacterial soap

Vitamin D Deficiency Predisposes You to Depression

Vitamin D deficiency is another important biological factor that can play a significant role in mental health. In one 2006 study,15 seniors with vitamin D levels below 20 ng/ml were found to be 11 times more prone to be depressed than those with higher levels. It’s worth noting that the mean vitamin D level was just under 19 ng/ml, which is a severe deficiency state. In fact, 58 percent of the participants had levels below 20 ng/ml. A 2007 study16 suggested that vitamin D deficiency is responsible for symptoms of depression and anxiety in patients with fibromyalgia. Vitamin D deficiency is also a well-recognized cause in Seasonal Affective Disorder17 (SAD). A double-blind randomized trial18 published in 2008 also concluded that:

“It appears to be a relation between serum levels of 25(OH)D and symptoms of depression. Supplementation with high doses of vitamin D seems to ameliorate these symptoms indicating a possible causal relationship.”

More recently, researchers19 found that seniors with depression had vitamin D levels that were 14 percent lower than those who were not depressed. Here, those with vitamin D levels below 20 ng/ml had an 85 percent increased risk of depression, compared to those with levels above 30 ng/ml. Yet another paper20 published in 2011 noted that:

“Effective detection and treatment of inadequate vitamin D levels in persons with depression and other mental disorders may be an easy and cost-effective therapy which could improve patients’ long-term health outcomes as well as their quality of life.”

Based on the evaluation of healthy populations that get plenty of natural sun exposure, the optimal range for general physical and mental health appears to be somewhere between 50 and 70 ng/ml. So, if you’re depressed, you’d be well advised to get your vitamin D level checked, and to address any insufficiency or deficiency. The D*Action Project by GrassrootsHealth is one cost effective testing solution. As for optimizing your levels, sensible sun exposure is the ideal way. Alternatively, use a tanning bed with an electronic ballast, and/or an oral vitamin D3 supplement.  GrassrootsHealth has a helpful chart showing the average adult dose required to reach healthy vitamin D levels based upon your measured starting point. Keep in mind that if you opt for a vitamin D supplement, you also need to take vitamin K2 and magnesium, as these nutrients work in tandem.

There Are Many Alternatives to Drug Treatment

Antidepressant drugs come with a long laundry list of risks, and are therefore best left as a last resort, if all else fails. Medical journalist and Pulitzer Prize nominee Robert Whitaker has detailed the many drawbacks and benefits of various treatments in his two books: Mad in America, and Anatomy of an Epidemic: Magic Bullets, Psychiatric Drugs, and the Astonishing Rise of Mental Illness in America, noting that physical exercise actually comes out on top in most studies—even when compared against antidepressant drugs.

Exercise primarily works by helping to normalize your insulin levels while simultaneously boosting “feel good” hormones in your brain. But researchers have also discovered that exercise allows your body to eliminate kynurenine, a harmful protein associated with depression.21 And, again showing the link between inflammation and depression, your body metabolizes kynurenine in the first place via a process that is activated by stress and inflammatory factors… While I addressed several dietary factors to restore health to your gut, I also recommend supplementing your diet with a high quality animal-based omega-3 fat, such as krill oil. This may be the single most important nutrient for optimal brain function, thereby easing symptoms of depression. Vitamin B12 deficiency can also contribute to depression, and affects one in four people.

Last but not least, make sure you get enough sleep. The link between depression and lack of sleep is well established. Of the approximately 18 million Americans with depression, more than half of them struggle with insomnia. While it was long thought that insomnia was a symptom of depression, it now seems that insomnia may precede depression in some cases.22 Recent research also found that sleep therapyresulted in remarkable improvements in depressed patients. The take-home message here is that one or more lifestyle factors may be at the heart of your depression, so you’d be well advised to address the factors discussed in this article before resorting to drug treatment—which science has shown is no more effective than placebo, while being fraught with potentially dangerous side effects.

Magnesium: An Invisible Deficiency That Could Be Harming Your Health

Magnesium: An Invisible Deficiency That Could Be Harming Your Health

Magnesium Deficiency

Story at-a-glance+

By Dr. Mercola

Magnesium is a mineral used by every organ in your body, especially your heart, muscles, and kidneys.1 If you suffer from unexplained fatigue or weakness, abnormal heart rhythms or even muscle spasms and eye twitches, low levels of magnesium could be to blame.

If you’ve recently had a blood test, you might assume it would show a magnesium deficiency. But only 1 percent of magnesium in your body is distributed in your blood, making a simple sample of magnesium from a serum magnesium blood test not very useful.

Most magnesium is stored in your bones and organs, where it is used for many biological functions. Yet, it’s quite possible to be deficient and not know it, which is why magnesium deficiency has been dubbed the “invisible deficiency.”

By some estimates, up to 80 percent of Americans are not getting enough magnesium and may be deficient. Other research shows only about 25 percent of US adults are getting the recommended daily amount of 310 to 320 milligrams (mg) for women and 400 to 420 for men.2

Even more concerning, consuming even this amount is “just enough to ward off outright deficiency,” according to Dr. Carolyn Dean, a medical and naturopathic doctor.

Magnesium Deficiency May Trigger 22 Medical Conditions

 

Download Interview Transcript

Magnesium is often thought of primarily as a mineral for your heart and bones, but this is misleading. Researchers have now detected 3,751 magnesium-binding sites on human proteins, indicating that its role in human health and disease may have been vastly underestimated.3

Magnesium is also found in more than 300 different enzymes in your body and plays a role in your body’s detoxification processes, making it important for helping to prevent damage from environmental chemicals, heavy metals, and other toxins. In addition, magnesium is necessary for:

  • Activating muscles and nerves
  • Creating energy in your body by activating adenosine triphosphate (ATP)
  • Helping digest proteins, carbohydrates, and fats
  • Serving as a building block for RNA and DNA synthesis
  • Acting as a precursor for neurotransmitters like serotonin

Dr. Dean has studied and written about magnesium for more than 15 years. The latest addition of her book, The Magnesium Miracle, came out in 2014 and in it you can learn about 22 medical areas that magnesium deficiency triggers or causes, all of which have all been scientifically proven. This includes:4

Anxiety and panic attacks Asthma Blood clots
Bowel diseases Cystitis Depression
Detoxification Diabetes Fatigue
Heart disease Hypertension Hypoglycemia
Insomnia Kidney disease Liver disease
Migraine Musculoskeletal conditions (fibromyalgia, cramps, chronic back pain, etc.) Nerve problems
Obstetrics and gynecology (PMS, infertility, and preeclampsia) Osteoporosis Raynaud’s syndrome
Tooth decay

Early signs of magnesium deficiency include loss of appetite, headache, nausea, fatigue, and weakness. An ongoing magnesium deficiency can lead to more serious symptoms, including:

Numbness and tingling Muscle contractions and cramps Seizures
Personality changes Abnormal heart rhythms Coronary spasms

The Role of Magnesium in Diabetes, Cancer, and More

Most people do not think about magnesium when they think about how to prevent chronic disease, but it plays an essential role. For instance, there have been several significant studies about magnesium’s role in keeping your metabolism running efficiently—specifically in terms of insulin sensitivity, glucose regulation, and protection from type 2 diabetes.

Higher magnesium intake reduces risk of impaired glucose and insulin metabolism and slows progression from pre-diabetes to diabetes in middle-aged Americans.5Researchers stated, “Magnesium intake may be particularly beneficial in offsetting your risk of developing diabetes, if you are high risk.”

Multiple studies have also shown that higher magnesium intake is associated with a higher bone mineral density in both men and women,6 and research from Norway has even found an association between magnesium in drinking water and a lower risk of hip fractures.7

Magnesium may even help lower your risk of cancer, and a study published in theAmerican Journal of Clinical Nutrition showed that higher intakes of dietary magnesium were associated with a lower risk of colorectal tumors.8

Results from the meta-analysis indicated that for every 100-mg increase in magnesium intake, the risk of colorectal tumor decreased by 13 percent, while the risk of colorectal cancer was lowered by 12 percent. The researchers noted magnesium’s anti-cancer effects may be related to its ability to reduce insulin resistance, which may positively affect the development of tumors.

Surprising Factors That Influence Your Magnesium Levels

Seaweed and green leafy vegetables like spinach and Swiss chard can be excellent sources of magnesium, as are some beans, nuts, and seeds, like pumpkin, sunflower, and sesame seeds. Avocados also contain magnesium. Juicing your vegetables is an excellent option to ensure you’re getting enough of them in your diet.

However, most foods grown today are deficient in magnesium and other minerals, so getting enough isn’t simply a matter of eating magnesium-rich foods (although this isimportant too). According to Dr. Dean:

“Magnesium is farmed out of the soil much more than calcium… A hundred years ago, we would get maybe 500 milligrams of magnesium in an ordinary diet. Now we’re lucky to get 200 milligrams.”

Herbicides, like glyphosate also act as chelators, effectively blocking the uptake and utilization of minerals in so many foods grown today. As a result, it can be quite difficult to find truly magnesium-rich foods. Cooking and processing further depletes magnesium.

Meanwhile, certain foods can actually influence your body’s absorption of magnesium. If you drink alcohol in excess, for instance, it may interfere with your body’s absorption of vitamin D, which in turn is helpful for magnesium absorption. If you eat a lot of sugar, this can also cause your body to excrete magnesium through your kidneys, “resulting in a net loss,” according to Dr. Danine Fruge, associate medical director at the Pritikin Longevity Center in Florida.9 The following factors are also associated with lower magnesium levels:10

  • Excessive intake of soda or caffeine
  • Menopause
  • Older age (older adults are more likely to be magnesium deficient because absorption decreases with age and the elderly are more likely to take medications that can interfere with absorption)
  • Certain medications, including diuretics, certain antibiotics (such as gentamicin and tobramycin), corticosteroids (prednisone or Deltasone), antacids, and insulin
  • An unhealthy digestive system, which impairs your body’s ability to absorb magnesium (Crohn’s disease, leaky gut, etc.)

Calcium, Vitamin K2, and Vitamin D Must Be Balanced with Magnesium

It may seem like you could remedy the risks of low magnesium simply by taking a supplement, but it’s not quite that simple. When you’re taking magnesium, you need to consider calcium, vitamin D3 and vitamin K2 as well, since these all work synergistically with one another. Excessive amounts of calcium without the counterbalance of magnesium can lead to a heart attack and sudden death, for instance. Research on the Paleolithic or caveman diet has shown that the ratio of calcium to magnesium in the diet that our bodies evolved to eat is 1-to-1.11Americans in general tend to have a higher calcium-to-magnesium ratio in their diet, averaging about 3.5-to-1.

If you have too much calcium and not enough magnesium, your muscles will tend to go into spasm, and this has consequences for your heart in particular. “What happens is, the muscle and nerve function that magnesium is responsible for is diminished. If you don’t have enough magnesium, your muscles go into spasm. Calcium causes muscle to contract. If you had a balance, the muscles would do their thing. They’d relax, contract, and create their activity,” Dr. Dean explains.

When balancing calcium and magnesium, also keep in mind that vitamins K2 and D need to be considered. These four nutrients perform an intricate dance together, with one supporting the other. Lack of balance between these nutrients is one of the reasons why calcium supplements have become associated with increased risk of heart attacks and stroke, and why some people experience vitamin D toxicity. Part of the explanation for these adverse side effects is that vitamin K2 keeps calcium in its appropriate place. If you’re K2 deficient, added calcium can cause more problems than it solves, by accumulating in the wrong places, like your soft tissue.

Similarly, if you opt for oral vitamin D, you need to also consume it in your food or take supplemental vitamin K2 and more magnesium. Taking mega doses of vitamin D supplements without sufficient amounts of K2 and magnesium can lead to vitamin D toxicity and magnesium deficiency symptoms, which include inappropriate calcification that may damage your heart.

Tips for Increasing Your Magnesium Levels

One way to really increase your magnesium, as well as many other important plant-based nutrients, is by juicing your greens. I typically drink one pint to one quart of fresh green vegetable juice every day, and this is one of my primary sources of magnesium. Organic foods may have more magnesium if grown in nutrient-rich soils but it is very difficult to make that determination. If you opt for a supplement, be aware that there are a wide variety of magnesium supplements on the market, because magnesium must be bound to another substance. There’s simply no such thing as a 100 percent magnesium supplement.

The substance used in any given compound can affect the absorption and bioavailability of the magnesium, and may provide slightly different, or targeted, health benefits. The table that follows summarizes some of the differences between the various forms. Magnesium threonate and citrate are some of the best sources, as it seems to penetrate cell membranes, including your mitochondria, which results in higher energy levels. Additionally, it also penetrates your blood-brain barrier and seems to do wonders to treat and prevent dementia and improve memory. If you take a supplement, you can use the “bowel test” to determine if you’re taking too much magnesium. Dr. Dean explains:12

“The best way to tell if you are getting enough magnesium is the “bowel test”. You know when you have too much magnesium when your stools become loose. This, in fact, may be a blessing for people with constipation… [which] is one of the many ways magnesium deficiency manifests.”

Besides taking a supplement, another way to improve your magnesium status is to take regular Epsom salt baths or foot baths. Epsom salt is a magnesium sulfate that can absorb into your body through your skin. Magnesium oil can also be used for topical application and absorption. Whatever supplement you choose, be sure to avoid any containing magnesium stearate, a common but potentially hazardous additive.

Magnesium glycinate is a chelated form of magnesium that tends to provide the highest levels of absorption and bioavailability and is typically considered ideal for those who are trying to correct a deficiency. Magnesium oxide is a non-chelated type of magnesium, bound to an organic acid or a fatty acid. Contains 60 percent magnesium, and has stool softening properties
Magnesium chloride/Magnesium lactate contain only 12 percent magnesium, but has better absorption than others, such as magnesium oxide, which contains five times more magnesium Magnesium sulfate/Magnesium hydroxide (milk of magnesia) are typically used as laxatives. Be aware that it’s easy to overdose on these, so ONLY take as directed
Magnesium carbonate, which has antacid properties, contains 45 percent magnesium Magnesium taurate contains a combination of magnesium and taurine, an amino acid. Together, they tend to provide a calming effect on your body and mind
Magnesium citrate is magnesium with citric acid, which like most magnesium supplements has laxative properties but is well absorbed and cost effective Magnesium threonate is a newer, emerging type of magnesium supplement that appears promising, primarily due to its superior ability to penetrate the mitochondrial membrane, and may be the best magnesium supplement on the market

Neuroplasticity Studies Reveal Your Brain’s Amazing Malleability

January 23, 2015 By Sherri

Story at-a-glance+

By Dr. Mercola

As time goes by, science provides more and more evidence that your brain is malleable and continually changing in response to your lifestyle, physiology, and environment.

This concept is called neuroplasticity, or brain plasticity—meaning, you are literally reforming your brain with each passing day. It used to be thought that your brain was static, except during some critical developmental periods, but today, we know this isn’t true.

Your brain possesses the remarkable ability to reorganize pathways, create new connections and, in some cases, even create new neurons throughout your entire lifetime.

Our views of the nature of the brain have changed in a similar way as our views of DNA. It used to be thought that DNA did not change—in other words, you’re stuck with what you’re born with.

This, too, has been disproven by researchers like Bruce Lipton, who have introduced an entirely new branch of biological science called epigenetics. Your DNA changes continuously based on your experiences, emotions, and environment.

The point is, you have much more control over your body, mind, and brain than you might think. If you can mold and shape your brain, you are not entirely at the mercy of your genetics or the neural pathways you brought into this world or formed as a child—and this is great news!

New Study Shows How Quickly Your Brain Can Rewire Itself

A recent study1 discussed in Scientific American2 illuminates your brain’s remarkable ability to rewire itself in response to experience. Mice with amblyopia or “lazy eye” (partial blindness caused by visual deprivation early in life) improved faster if they were exposed to visual stimuli while running on a treadmill.

Amblyopia can happen to someone born with a droopy eyelid, cataract, or other defect not corrected early in life. If the eye is opened in adulthood, recovery is usually slow and incomplete.

In this experiment, researchers induced amblyopia in mice by suturing one eye shut for several months. After the sutures were removed, the mice were shown a “noisy” visual pattern while running on a treadmill for four hours a day for three weeks.

The pattern was chosen to activate nearly all the cells in the animals’ primary visual cortex. After two weeks, the animals’ responses were comparable to those of normal mice that had never been visually deprived. Neither running nor visual stimulation alone had this effect.

The researchers believe the impressive response has something to do with built in mechanisms that allow animals to keep track of environmental stimuli from a distance:

“It makes sense to put the visual system in a high-gain state when you’re moving through the environment, because vision tells you about far away things, whereas touch only tells you about things that are close.”

The scientists do not know whether or not their findings apply to humans but are planning further studies. The current thinking is that “activity stimulates plasticity”—and this applies to your brain as well as other parts of your body. Plasticity is what allows tissues to heal.3

Neurons That Fire Together, Wire Together—And Neurons That Fire Apart, Wire Apart

Neuroplasticity is, in simple terms, the ability of your brain to change and adapt in response to experience.4 You can think of those neurological changes as your brain’s way of tuning itself to meet your needs.

There are two types of brain plasticity—functional plasticity (your brain’s ability to move functions from a damaged area to undamaged areas) and structural plasticity (its ability to actually change its physical structure as a result of learning).5

Think about what happens when you’re learning a new skill. The more you focus and practice something, the better you become, and this is a result of new neural pathways that form in response to your learning efforts. At the same time, your brain is undergoing “synaptic pruning”—elimination of the pathways you no longer need.

Until recently, it was believed that the human brain, which consists of approximately 100 billion neural cells, could not generate new ones. The old model assumed that you were born with a finite number of brain cells, and when a cell died, no new cell grew in its place.

This old model is no longer relevant, as it’s been proven that certain areas of your brain can generate new cells (neurogenesis), as well as creating new neural pathways.

Environment plays an essential role in the process, but genetics can also have an influence. These neural processes have been well documented in people recovering from stroke-related brain damage.

This phenomenon even applies to emotional states. For example, if you have a history of anxiety, your neural pathways become wired for anxiety. If you develop tools to feel calm and peaceful more of the time, those anxiety pathways are pruned away from lack of activity—“use it it or lose it” really applies here.

According to “What is Neuroplasticity:”6

“It was once believed that the human brain had a relatively small window to develop new pathways in our life span, then after that the pathways became immutable.

This old theory thought our ability to generate new pathways dropped off sharply around the age of 20, and then became permanently fixed around the age of 40.

New studies have shown through the use PET, and MRI brain scanning technology, that new neural cells are generated throughout life as well as new neural pathways. Even the elderly are capable of creating measurable changes in brain organization. These changes are not always easy but can happen through concerted focus on a defect area.”

How the Science of Neuroplasticity Changes the Game

Your brain’s plasticity is also controlled by your diet and lifestyle choices, including exercise. Despite what the media tells you, your brain is not “programmed” to shrink and fail as you age. The foods you eat, exercise, emotional states, sleep patterns, and your level of stress—all of these factors influence your brain from one moment to the next.

Any given gene is not in a static “on” or “off” position. You may be a carrier of a gene that never gets expressed, simply because you never supply the required environment to turn it on. As neurologist David Perlmutter explains:

“We interact with our genome every moment of our lives, and we can do so very, very positively. Keeping your blood sugar low is very positive in terms of allowing the genes to express reduced inflammation, which increase the production of life-giving antioxidants. So that’s rule number one: You can change your genetic destiny. Rule number two: you can change your genetic destiny to grow new brain cells, specifically in the hippocampus… 

Your brain’s memory center regenerates. You are constantly growing new brain cells into your 50s, 60s, 80s, and 90s – throughout your lifetime – through a process called neurogenesis. That said, these two ideas come together because you can turn on your genes through lifestyle choices that enhance neurogenesis and that enhance regrowth of cells and expansion of your brain’s memory center. This was proven by researchers recently. They demonstrated that there are factors under our control that can make that happen.”

For Brain Health, You Need Physical AND Mental Exercise

The blind mice study is just one more piece of evidence for how important exercise is for your brain. Recent science has shown that physical exercise is as important as mental exercise when it comes to keeping your mind fit.7, 8 A number of studies show that exercise can promote growth of new brain cells, enlarge your memory center, improve IQ scores, and help prevent brain deterioration as you age.

One study found that one 20-minute weight training session improved memory. In a year-long study, individuals who exercised were actually growing and expanding their brain’s memory center one to two percent per year, whereas typically that center would have continued to decline in size. Strength training, especially high-intensity interval training (HIIT), is especially beneficial for boosting long-term memory and reducing your risk for dementia.

Exercise prompts nerve cells to release one growth factor in particular, called brain-derived neurotrophic factor (BDNF). BDNF triggers numerous other chemicals that promote neural health and directly benefit cognitive functions, including learning. Fasting also triggers BDNF, andexercising while fasting can go a long way toward keeping your brain and muscles biologically young.

According to brain plasticity expert Dr. Michael Merzenich (interviewed in the video above), engaging in challenging new activities throughout your life, staying socially active, and practicing “mindfulness” are other ways to boost your brain function. He also stresses the importance of having a genuine interest in your chosen activities. Just going through the motions is not enough to build these neural pathways—you have to really care about what you’re learning.

Protect Your Brain with Wise Lifestyle Choices

Lifestyle strategies proven to promote neurogenesis and target BDNF include the following:

  • Exercise, especially high-intensity interval training
  • Reducing overall calorie consumption
  • Reducing carbohydrate consumption (especially grains and sugars)
  • Enough healthy fat consumption to eliminate insulin resistance
  • Enough high-quality omega-3 fats and eliminating damaged omega-6 fats (processed vegetable oils) will improve your omega-3 to omega-6 ratio. I prefer krill oil to fish oil, as krill oil also contains astaxanthin, which is particularly beneficial for your brain. Astaxanthin is a carotenoid that’s very good for reducing free radical-mediated damage to fat—and your brain is 60 or 70 percent fat

There are three other important considerations for brain health:

  1. Vitamin D: This vitamin/hormone plays a fundamental role in brain health, inflammation, and immune function. Vitamin D influences the expression of 2000-3000 genes. Researchers have located metabolic pathways for vitamin D in the brain’s hippocampus and cerebellum, areas that are involved in planning, information processing, and memory formation. In older adults, research has shown that low vitamin D levels are associated with poorer brain function. Appropriate sun exposure is all it takes to keep your levels where they need to be. If this is not an option, a tanning bed that uses electronic ballasts is the next best alternative, followed by a vitamin D3 supplement.
  2. Gut Health: Your gut is your “second brain;” gut bacteria transmit information from your GI tract to your brain via your vagus nerve. Just as you have neurons in your brain, you also have neurons in your gut—including neurons that produce neurotransmitters like serotonin, which is linked to mood. Abnormal gut flora has been associated with abnormal brain development. In addition to avoiding sugar, one of the best ways to support gut health is to consume beneficial bacteria. You can take a probiotic supplement, but I’m particularly fond of using fermented vegetables, as they can deliver extraordinarily high levels of beneficial bacteria for minimal cost.
  3. Choline: Choline reduces inflammation, plays a roll in nerve communications, and prevents the buildup of homocysteine in your blood (elevated homocysteine is linked to heart disease). Eggs and meat are two of the best dietary sources of choline. If you do not consume animal foods, you may be at risk of a deficiency and want to consider supplementation. If you’re pregnant, make sure your diet includes plenty of choline-rich foods, as research shows higher choline intake leads to changes in epigenetic markers in the fetus.

Stress Hormones Will Shrink Your Brain—So Shrink Your Stress Instead

Research shows that how you respond to stress may be a key factor in how your brain ages. An animal study9 showed how elevated stress hormones may speed up short-term memory loss in older adults. Previous research has also linked chronic stress with working memory impairment.10Chronic stress can actually trigger a genetic switch that results in loss of brain volume, and this in turn contributes to both emotional and cognitive impairment.11 Given this, it makes sense why a recent study12 showed that your daily stress responses have long-term implications for your mental health.

Researchers found that people with increased stress have increased risk for mental disorders a decade later, especially anxiety and depression. The message is clear: managing daily stress is a key factor in keeping your brain healthy as you age, and this has implications for everything from depression to dementia. My favorite tool for stress management is Emotional Freedom Technique (EFT), an energy psychology tool that can help reprogram your body’s reactions to everyday stress.

Recent research has shown that EFT (or “tapping”) significantly increases positive emotions, such as hope and enjoyment, and decreases negative emotional states, such as anger and shame. EFT has been shown to lower cortisol levels13 (one of your major stress hormones) and is actually an epigenetic intervention that can alter gene expression.14 EFT is a powerful tool for transforming your stress reactions into more adaptive ones, and replacing old dysfunctional patterns with new. For more information, I invite you to visit my EFT page.

You CAN Take Control of Your Brain Function…

Again, the good news is that you’re not at the mercy of your genes or the dysfunctional neural pathways you might have developed in childhood. Your brain can literally be rewired, and you are doing so already—every day of your life! Old neural patterns are continuously being overwritten by new ones. Diet, exercise, sleep, stress, and other lifestyle choices all impact your brain’s structure and function, and how “gracefully” it ages. You are in the driver’s seat, so pay attention to the choices you make today, as they are forming the brain you’ll have tomorrow.

Vitamin D Deficiency Linked to Many Disorders

January 23, 2015 By Sherri

Vitamin D DeficiencyJanuary 02, 2014

Story at-a-glance+

By Dr. Mercola

Vitamin D research continues to impress upon us the importance of appropriate sun exposure as the ideal way to optimize your vitamin D levels.

Winter limits sun exposure for many up to six months of the year. During those times, your next best bet would be artificial UVB light, as UV ray exposure also appears to have health benefits above and beyond the production of vitamin D.

One of the most damaging elements of standard tanning beds are the magnetic ballasts (which make that loud buzzing noise you hear in many tanning salons). If an electronic ballast is used, there are far less damaging EMFs, which provide most of the danger from tanning beds.

The other concern is related to the bulbs used, as some may contain only UVA light which is primarily responsible for the tan, but doesn’t increase vitamin D levels.  For much of the northern hemisphere, vitamin D production is not possible from the sun during the winter months.  You must use artificial UVB light or obtain vitamin D from your diet during this time.

The benefits of UVB exposure from the sun or artificial light include but are not limited to the production of nitric oxide—a compound that lowers your blood pressure. Despite its name, vitamin D is not a vitamin. It’s actually a potent neuroregulatory steroidal hormone, which helps explain some of its health impacts.

It has become abundantly clear that vitamin D deficiency is a growing epidemic across the world and could be contributing to hundreds of common health problems. In fact, correcting your vitamin D deficiency may cut your risk of dying from any cause by 50 percent, according to one analysis.

If this sounds too incredible to be true, consider that vitamin D influences nearly 3,000of your 24,000 genes. This occurs via vitamin D receptors, which can be found throughout your body, and should come as no great surprise given that humans evolved in the sun.

Vitamin D Beneficially Affects Gene Activity

Just one example of an important gene that vitamin D up-regulates is your ability to fight infections and chronic inflammation. It also produces over 200 anti-microbial peptides, the most important of which is cathelicidin, a naturally-occurring broad-spectrum antibiotic.

This is one of the explanations for why vitamin D is so effective against colds and influenza.

According to a January 2013 press release by Orthomolecular Medicine,1 there are now 33,800 medical papers with vitamin D in the title or abstract, and this veritable mountain of research shows that vitamin D has far-reaching benefits to your physical and mental health. Such research has shown that vitamin D can improve:

  • Pregnancy outcomes (reduced risk of Cesarean section and pre-eclampsia)
  • Type 1 and 2 diabetes
  • Heart disease and stroke
  • Autism, Alzheimer’s, and other brain dysfunction
  • Bacterial and viral infections

Some of the most recently published studies, which I’ll review here, demonstrate how boosting your vitamin D levels can improve depression and pain in diabetics, Crohn’s disease, and breast cancer.

Relevance of Vitamin D in Crohn’s Disease

While previous research has associated low vitamin D levels with an increased risk ofCrohn’s disease and shown that correcting your vitamin D deficiency can improve symptoms of the disease,2 one of the most recent studies3 found a “significant interaction between vitamin D levels and Crohn’s disease susceptibility, as well as a significant association between vitamin D levels and genotype.”

Serum vitamin D levels were found to be significantly lower in patients with Crohn’s disease. Of the seven DNA sequence variations examined for effects, two variants showed a significant association with vitamin D levels in those with Crohn’s, and four variants were associated with vitamin D levels among controls.

In short, it shows that vitamin D can affect genetic expression associated with Crohn’s disease, and make matters either better or worse, depending on whether you have enough of it or not.

Vitamin D May Reduce Depression and Pain

In related news, vitamin D supplementation has been found to reduce both depression and pain in diabetic women. As reported by PsychCentral:4

“The investigators set out to determine how vitamin D supplementation might affect women with type 2 diabetes who were also suffering from depression.

At the beginning of the study, 61 percent of women reported neuropathic pain, such as shooting or burning pain in their legs and feet, and 74 percent had sensory pain, such as numbness and tingling in their hands, fingers and legs.

During the course of the study, the participants took a 50,000 IU vitamin D2 supplement every week for 6 months. By the end of the study, the women’s depression levels had significantly improved following the supplementation.

Furthermore, participants who suffered from neuropathic and/or sensory pain at the beginning of the study reported that these symptoms decreased at 3 and 6 months following vitamin D2 supplementation.”

According to lead researcher Todd Doyle, Ph.D., vitamin D supplementation “is a promising treatment for both pain and depression in type 2 diabetes.” However, I would note that you’d probably get even better results using vitamin D3 rather than prescription D2. In fact, previous research suggests vitamin D2 might do more harm than good in the long term…

Why I Recommend Vitamin D3 Over D2

Drisdol is a synthetic form of vitamin D2—made by irradiating fungus and plant matter—and is the form of vitamin D typically prescribed by doctors. This is not the type produced by your body in response to sun or safe tanning bed exposure, which is vitamin D3.

According to a 2012 meta-analysis by the Cochrane Database,5 which assessed mortality rates for people who supplemented their diets with D2 versus those who did so with D3, there are significant differences in outcome between the two. The analysis of 50 randomized controlled trials, which included a total of 94,000 participants, showed:

  • A six percent relative risk reduction among those who used vitamin D3
  • A two percent relative risk increase among those who used D2

That said, the featured research certainly sheds light on the role vitamin D can play in the management of type 2 diabetes and associated side effects. And when you consider that an estimated 60 percent of type 2 diabetics are vitamin D deficient,6there’s certainly plenty of room for improvement.

Additional support for the theory that vitamin D can be beneficial in the fight against type 2 diabetes was published in last year.7 Here, the researchers found “a strong additive interaction between abdominal obesity and insufficient 25(OH)D in regard to insulin resistance.” They also claim 47 percent of the increased odds of insulin resistance can be explained by the interaction between insufficient vitamin D levels and a high body mass index (BMI).

Yet another study 8 published in Diabetes Care also suggests vitamin D supplements may help prevent type 2 diabetes mellitus in people with pre-diabetes. While the study is only an observational one and cannot establish causality, the researchers report that the participants who had the highest vitamin D levels were 30 percent less likely to develop diabetes during the three-year evaluation period, compared to those with the lowest levels.

Cut Your Breast Cancer Risk with Vitamin D, Cancer Surgeon Suggests

Meanwhile, a recent Science World Report9 highlighted the recommendation by British breast cancer surgeon, Professor Kefah Mokbel, who urges women to take daily vitamin D supplements to cut their risk of breast cancer. According to the featured article:

“Prof. Mokbel has also requested Jeremy Hunt, the Health Secretary, to make [vitamin D] pills freely available as this would result in saving about a 1,000 lives annually. ‘I am calling for all women from the age of 20 to be given free vitamin D supplements on the NHS because it is effective in protecting against breast cancer,’ Prof. Mokbel said.

…[R]esearch10, 11 conducted by the Creighton University School of Medicine in Omaha, Neb, which analyzed menopausal women from rural eastern Nebraska for over four years, revealed that taking vitamin D supplements along with calcium cut about 60 percent risk of cancer, including breast, lung and colon cancer…’It’s inexpensive, it’s safe, and it’s easy to take. It’s something that should be considered by a lot of people,’ says Joan Lappe, professor of nursing and medicine at Creighton University School of Medicine in Omaha, Neb. ‘It’s low-risk with maybe a high pay-off.’”

Vitamin D Is Critical for Cancer Prevention

Indeed, an ever growing number of studies show that vitamin D has tremendous protective effects against a variety of different cancers, including pancreatic, lung, ovarian, breast, prostate, and skin cancers. Theories linking vitamin D deficiency to cancer have been tested and confirmed in more than 200 epidemiological studies, and understanding of its physiological basis stems from more than 2,500 laboratory trials.

For example, a 2007 study published in the American Journal of Preventive Medicine12concluded that a serum 25(OH)D level of more than 33 ng/mL was associated with a 50 percent lower risk of colorectal cancer. And research published in the International Journal of Cancer two years ago13 found that a mere 10 ng/ml increase in serum vitamin D levels was associated with a 15 percent reduction in colorectal cancer incidence and 11 percent reduction in breast cancer incidence.

Another 2007 study published in the American Journal of Clinical Nutrition14 found that after four years of follow up, cancer-free survival was 77 percent higher in women who received 1,100 IU vitamin D and 1,450 mg calcium per day, compared to those who received either a placebo or calcium by itself. According to Carole Baggerly, founder ofGrassrootsHealth, as much as 90 percent of ordinary breast cancer may in fact be related to vitamin D deficiency. Breast cancer has even been described as a “vitamin D deficiency syndrome,” much like the commoncold and seasonal flu.

Most Important—Maintaining Optimal Vitamin D Serum Levels

Of utmost importance is the maintenance of a therapeutically beneficial serum level year-round. Here, studies indicate that the bare minimum for cancer prevention is around 40 ng/ml. Research suggests an ideal level might be around 60-80 ng/ml. A 2009 review article15 titled: “Vitamin D for Cancer Prevention: Global Perspective,” published in Annals of Epidemiology states that:

“Higher serum levels of the main circulating form of vitamin D, 25-hydroxyvitamin D (25(OH)D), are associated with substantially lower incidence rates of colon, breast, ovarian, renal, pancreatic, aggressive prostate and other cancers. Epidemiological findings combined with newly discovered mechanisms suggest a new model of cancer etiology that accounts for these actions of 25(OH)D and calcium. Its seven phases are disjunction, initiation, natural selection, overgrowth, metastasis, involution, and transition (abbreviated DINOMIT). Vitamin D metabolites prevent disjunction of cells and are beneficial in other phases.

It is projected that raising the minimum year-around serum 25(OH)D level to 40 to 60 ng/mL (100–150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three fourths of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial.

Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal, or prostate cancer by half... The time has arrived for nationally coordinated action to substantially increase intake of vitamin D and calcium.” [Emphasis mine]

General Supplementation Guidelines

As a general guideline, research by GrassrootsHealth suggests that adults need about 8,000 IUs per day to achieve a serum level of 40 ng/ml. That said, I strongly recommend boosting your vitamin D levels through appropriate sun exposure whenever possible. If you do opt for a vitamin D supplement, please remember that you also need to boost your intake of vitamin K2 through food and/or a supplement. If you’re getting your vitamin D from the sun, this is not as critical, although you’d be wise to make sure you’re getting sufficient amounts of vitamin K2 from your diet either way.

How do you know if your vitamin D level is in the right range? The most important factor is having your vitamin D serum level tested every six months, as people vary widely in their response to ultraviolet exposure or oral D3 supplementation. Your goal is to reach a clinically relevant serum level of 50-70 ng/ml, and to maintain that level year-round.  You should test at your highest point, which is typically August and again at your lowest point, which is usually February.

Knowing your vitamin D levels is one of the most important tests you can take, so please, if you haven’t checked your levels before do it now – I cannot stress the importance of this enough.

How Vitamin D Performance Testing Can Help Optimize Your Health

A robust and growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention. Vitamin D affects your DNA through vitamin D receptors (VDRs), which bind to specific locations of the human genome. Scientists have identified nearly 3,000 genes that are influenced by vitamin D levels, and vitamin D receptors have been found throughout the human body.

Is it any wonder then that no matter what disease or condition is investigated, vitamin D appears to play a crucial role? This is why I am so excited about the D*Action Projectby GrassrootsHealth. It is showing how you can take action today on known science with a consensus of experts without waiting for institutional lethargy. It has shown how by combining the science of measurement (of vitamin D levels) with the personal choice of taking action and, the value of education about individual measures that one can truly be in charge of their own health.

In order to spread this health movement to more communities, the project needs your involvement. This was an ongoing campaign during the month of February, and will become an annual event.

To participate, simply purchase the D*Action Measurement Kit and follow the registration instructions included. (Please note that 100 percent of the proceeds from the kits go to fund the research project. I do not charge a single dime as a distributor of the test kits.)

As a participant, you agree to test your vitamin D levels twice a year during a five-year study, and share your health status to demonstrate the public health impact of this nutrient. There is a $65 fee every six months for your sponsorship of this research project, which includes a test kit to be used at home, and electronic reports on your ongoing progress. You will get a follow up email every six months reminding you “it’s time for your next test and health survey.”

Sunshine is a Source of Life

November 6, 2014 By Sherri

Sunshine HealthI LOVE Colorado!! Just went outside for a visit with my girls (Pumpkin and Cookie), in my jammies and t-shirt! And it was only 40 degrees!

There is way too much hype about avoiding the sun. The truth is, sunshine is imperative for our brain and immune health!

Sunshine in the morning helps the metabolism and brain chemistry to kick into gear for the day. It can re-balance your sleep cycle when you stand in a window and look out into the lit up world for about 10 minutes. This tells your brain it is time to wake up, therefore making it easier to rise earlier and possibly fall asleep better, too!

Daylight is essential for your metabolic health, so step outside for a jog or walk first thing in the a.m. In fact, people who soak up the most sunlight early in the day have a lower body mass index (BMI) compared to those who are out in the sun later in the day. Northwestern University researchers speculate that early morning sunlight may help regulate your circadian rhythm, which controls countless functions in your body including how well you sleep, how much food you consume, and how much energy you burn—all essential components of a healthy metabolic rate (8 Surprising Ways You’re Slowing Your Metabolism, Prevention.com, November 2014).

Sunshine contains a powerful pack of healing rays and vitamins, including vitamin D.

A robust and growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention. Vitamin D affects your DNA through vitamin D receptors (VDRs), which bind to specific locations of the human genome. Scientists have identified nearly 3,000 genes that are influenced by vitamin D levels, and vitamin D receptors have been found throughout the human body (How Much Sunshine Does it Take to Make Enough Vitamin D?, Mercola.com, October 2009).

Lack of sunshine can lower your levels of D vitamins, immunity, brain function and raises your risk for cancer. Vitamin D deficiencies are found in people with immune and inflammatory disorders, cancer, Autism, ADD and more. Sunshine is the best way to get vitamin D. If it is not possible, taking a high quality supplement of D3 is best way to absorb and assimilate this precious vitamin.

Using sunglasses blocks the rays from getting into the pineal gland and sunscreen not only has toxic chemicals, but blocks the production of D vitamins. In fact, there is a lot of data about sunscreen actually causing vitamin D deficiencies and many other secondary health issues.

Following the advise of health officials to slather on sunscreen may increase your melanoma risk instead of decreasing it, which is certainly not what you want. Indeed, you never want to let yourself burn. However, if you practice safe sunning, you will avail yourself of all of the sun’s health benefits with none of the risk (Sensible Sun Exposure Can Help Prevent Melanoma, Breast Cancer and Hundreds of Other Health Problems, Mercola.com, July 01, 2013).

But make sure you practice safe doses of sunshine! Don’t burn and never look directly into the sun! If I am going to be outside for a long period of time, I use a natural, chemical free, mineral based sun block to avoid getting burned. If you take medicine or have a condition in which you are supposed to avoid the sunshine, please talk to your doctor!

Enjoy!
