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.

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.

New Study Shows Evidence That Vitamin K2 Positively Impacts Inflammation

New Study Shows Evidence That Vitamin K2 Positively Impacts Inflammation

Chronic Pain

Story at-a-glance+

By Dr. Mercola

Chronic inflammation is low-grade and systemic, often silently damaging your tissues over an extended period of time. This process can go on for decades without you noticing, until disease symptoms suddenly occur long after irreversible damage is done.

Chronic inflammation is the source of many diseases, including cancer, obesity, and heart disease, which essentially makes it the leading cause of death in the U.S.

Knowing how to keep chronic inflammation at bay is also invaluable in protecting your health, which brings us to a new study on vitamin K2 presented at the 13th International Nutrition and Diagnostics Conference (INDC 2013) in the Czech Republic.1

The study revealed that a specific type of vitamin K2 (MK-7) may help prevent inflammation. But before I get into the details, it’s important to understand the different forms that vitamin K comes in.

The Two Basic Types of Vitamin K – K1 and K2

Vitamin K can be classified as either K1 or K2:

    1. Vitamin K1: Found in green vegetables, K1 goes directly to your liver and helps you maintain a healthy blood clotting system. (This is the kind of K that infants need to help prevent a serious bleeding disorder.)

It is also vitamin K1 that keeps your own blood vessels from calcifying, and helps your bones retain calcium and develop the right crystalline structure.

    1. Vitamin K2: Bacteria produce this type of vitamin K. It is present in high quantities in your gut, but unfortunately most is passed out in your stool. K2 goes straight to vessel walls, bones and tissues other than your liver.

It is present in fermented foods, particularly cheese and the Japanese food natto, which is by far the richest source of K2.

Vitamin K1 can convert to K2 in your body, but there are some problems with this; the amount of K2 produced by this process alone is typically insufficient. Making matters even more complex, there are several different forms of vitamin K2. MK-8 and MK-9 come primarily from dairy products. MK-4 and MK-7 are the two most significant forms of K2 and act very differently in your body:

    • MK-4 is a synthetic product, very similar to vitamin K1, and your body is capable of converting K1 into MK-4. However, MK-4 has a very short biological half-life of about one hour, making it a poor candidate as a dietary supplement.

After reaching your intestines, it remains mostly in your liver, where it is useful in synthesizing blood-clotting factors.

    • MK-7 is a newer agent with more practical applications because it stays in your body longer; its half-life is three days, meaning you have a much better chance of building up a consistent blood level, compared to MK-4 or K1. MK-7 is extracted from the Japanese fermented soy product called natto.

You could actually get loads of MK-7 from consuming natto, as it is relatively inexpensive and is available in most Asian food markets. Few Americans, however, tolerate its smell and slimy texture.

Vitamin K2 as MK-7 Helps Prevent Inflammation in Your Body

Vitamin K2, particularly menaquinone-7 (MK-7), has been the subject of much research because it stays active in your body longer so you are able to benefit from much lower levels. The study from the Czech Republic evaluated the role of MK-7 in inflammation and found that it prevents inflammation by inhibiting pro-inflammatory markers produced by white blood cells called monocytes.

NattoPharma reported:2

“The novel finding in our study supplements our three-year clinical study showing MK-7’s ability to slow down cardiovascular aging and osteoporosis, and it should further serve as the catalyst to create the urgency of daily consumption of MK-7… We know that in Western populations, most people do not obtain enough due to modern diet.

Our food is increasingly deficient in vitamin K2 in particular, and up to 98% of the general healthy population may be vitamin K2 insufficient with long-term detrimental impact on bone and cardiovascular health.”

It’s important to realize that dietary components can either trigger or preventinflammation from taking root in your body. For example, whereas synthetic trans fats and sugar, particularly fructose, will increase inflammation, eating healthy fats such as animal-based omega-3 fats found in krill oil or the essential fatty acid gamma linolenic acid (GLA) will help to reduce them.

MK-7 appears to be one more healthful natural substance that can be added to the anti-inflammatory list, and I’ll discuss the best food sources of this shortly.

As for inflammation in general, if you have not already addressed your diet, this would be the best place to start, regardless of whether you’re experiencing symptoms of chronic inflammation or not. To help you get started, I suggest following my freeOptimized Nutrition Plan, which starts at the beginner phase and systematically guides you step-by-step to the advanced level.

What Else Is Vitamin K2 Good For?

The health benefits of vitamin K2 go far beyond blood clotting, which is done by vitamin K1, and vitamin K2 also works synergistically with a number of other nutrients, including calcium and vitamin D. Its biological role is to help move calcium into the proper areas in your body, such as your bones and teeth. It also plays a role in removing calcium from areas where it shouldn’t be, such as in your arteries and soft tissues.

Dr. Kate Rheaume-Bleue, a naturopathic physician, estimates that about 80 percent of Americans do not get enough vitamin K2 in their diet to activate their K2 proteins to shuttle the calcium where it needs to be and remove it from the places where it shouldn’t be. Vitamin K2 deficiency leaves you vulnerable to a number of chronic diseases, including:

Osteoporosis Heart disease Heart attack and stroke
Inappropriate calcification, from heel spurs to kidney stones Brain disease Cancer

 

“I talked about vitamin K2 moving calcium around the body. Its other main role is to activate proteins that control cell growth. That means K2 has a very important role to play in cancer protection,” Rheaume-Bleue says. “When we’re lacking K2, we’re at much greater risk for osteoporosis, heart disease, and cancer. And these are three concerns that used to be relatively rare. Over the last 100 years, as we’ve changed the way we produced our food and the way we eat, they have become very common.”

Researchers are also looking into other health benefits, as well. For example, one study published in the journal Modern Rheumatology found that vitamin K2 has the potential to improve disease activity besides osteoporosis in those with rheumatoid arthritis (RA).3 Another, published in the journal Science found that vitamin K2 serves as a mitochondrial electron carrier, thereby helping maintain normal adenosine triphosphate (ATP) production in mitochondrial dysfunction, such as that found in Parkinson’s disease.4 Further, according to a 2009 Dutch study, subtypes MK-7, MK-8 and MK-9 in particular are associated with reduced vascular calcification even at small dietary intakes (as low as 1 to 2 mcg per day).5

What Are the Best Food Sources of Vitamin K2, Including MK-7?

You can obtain all the K2 you’ll need (about 200 micrograms) by eating 15 grams of natto daily, which is half an ounce. However, natto is generally not appealing to a Westerner’s palate, so you can also find vitamin K2, including MK-7, in other fermented foods. Fermented vegetables, which are one of my new passions, primarily for supplying beneficial bacteria back into your gut, can be a great source of vitamin K if you ferment your own using the proper starter culture.

We had samples of high-quality fermented organic vegetables made with our specific starter culture tested, and were shocked to discover that not only does a typical serving of about two to three ounces contain about 10 trillion beneficial bacteria, but it also contained 500 mcg of vitamin K2.

Note that not every strain of bacteria makes K2. For example, most yogurts have almost no vitamin K2. Certain types of cheeses are very high in K2, and others are not. It really depends on the specific bacteria. You can’t assume that any fermented food will be high in K2, but some fermented foods are very high in K2, such as natto. Others, such as miso and tempeh, are not high in K2. In my interview with Dr. Rheaume-Bleue, she identified the cheeses highest in K2 are Gouda and Brie, which contain about 75 mcg per ounce. Additionally, scientists have found high levels of MK-7 in a type ofcheese called Edam.

How Much Vitamin K2 Do You Need?

Although the exact dosing is yet to be determined, Dr. Cees Vermeer, one of the world’s top researchers in the field of vitamin K, recommends between 45 mcg and 185 mcg daily for adults. You must use caution on the higher doses if you take anticoagulants, but if you are generally healthy and not on these types of medications, I suggest 150 mcg daily. Fortunately, you don’t need to worry about overdosing on K2—people have been given a thousand-fold “overdose” over the course of three years, showing no adverse reactions (i.e., no increased clotting tendencies). If you have any of the following health conditions, you’re likely deficient in vitamin K2 as they are all connected to K2:

  • Do you have osteoporosis?
  • Do you have heart disease?
  • Do you have diabetes?

Please note also that if you opt for oral vitamin D, you also need to consume vitamin K2 in your food or take supplemental vitamin K2, as they worksynergistically together and an imbalance may actually be harmful. If you do not have any of those health conditions, but do NOT regularly eat high amounts of the following foods, then your likelihood of being vitamin K2 deficient is still very high:

  • Grass-fed organic animal products (i.e. eggs, butter, dairy)
  • Certain fermented foods such as natto, or vegetables fermented using a starter culture of vitamin K2-producing bacteria
  • Certain cheeses such as Brie and Gouda (as mentioned, these two are particularly high in K2, containing about 75 mcg per ounce)

If You’re Considering a Vitamin K2 Supplement…

There’s no way to test for vitamin K2 deficiency. But by assessing your diet and lifestyle as mentioned above you can get an idea of whether or not you may be lacking in this critical nutrient. The next best thing to dietary vitamin K2 is a vitamin K2 supplement. MK-7 is the form you’ll want to look for in supplements, because in a supplement form the MK-4 products are actually synthetic. They are not derived from natural food products containing MK-4. The MK-7– long-chain, natural bacterial-derived vitamin K2– is from a fermentation process, which offers a number of health advantages:

  • It stays in your body longer
  • It has a longer half-life, which means you can just take it once a day in very convenient dosing

Finally, remember to always take your vitamin K supplement with fat since it is fat-soluble and won’t be absorbed without it.
