Do You Need More Vitamin K2 As You Get Older

Men begin to lose bone density at age 55, and women begin during menopause due to the decline in oestrogen production. For this reason it is important to ensure you are getting enough calcium to your bones as you get older, so vitamin K2 does become more of a priority. Women should begin in middle age, before the menopause kicks in and causes bone loss faster.

In one 2013 study, it was found that children and adults over 40 were most likely to be deficient in vitamin K2, so children may also benefit from a change in diet or even a supplement of suitable strength.

Vitamin K2 May Prevent Wrinkles And Reverse Aging

Collagen and elastin are two of the components of skin that give it firmness and elasticity. As skin ages, it loses both collagen and elastin, and its youthful appearance along with them.

Skin cells appear to release matrix-GLA protein to prevent calcification of elastin in the skin.

One study looked at a genetic disorder where premature aging occurs.

It found that elastin is calcified due to the lack of Vitamin K2 activated matrix-GLA protein. Vitamin K2 could help maintain youthful skin activating Matrix-GLA and in turn preventing calcification of elastin.

Vitamin K: Form And Structure

Eighty-four years ago, while investigating the effects of a low-fat diet fed to chickens, Danish scientist Henrik Dam discovered vitamin K. He found that the bleeding tendencies found in the chickens on that diet could be prevented when a diet with normal levels of fat was restored and vitamin K was added to their diets. From that point forward, vitamin K became known as the coagulation vitamin, the K coming from the German word koagulation.

Later, it was found that the fat-soluble compound needed for blood clotting existed in 2 forms: phylloquinone and menaquinone . Vitamin K1 is made in plants and algae green leafy vegetables are a particularly rich source. On the other hand, bacteria generate vitamin K2, which can also be found in meat, dairy, eggs, and fermented foods, such as cheese, yogurt, and nattoa Japanese dish of fermented soybeans.,

Even though the side chains of isoprenoid units of vitamin K differ in length, generally from 4 to 13 repeats , they are all used by the enzyme -glutamate carboxylase to activate a specific set of proteins, including proteins involved in blood coagulation, bone formation, and inhibition of soft tissue calcification. Both forms of vitamin K, K1 and K2, are essential in maintaining blood hemostasis and optimal bone and heart health through the role they play in inducing calcium use by proteins. Vitamin K, particularly vitamin K2, is essential for calcium use, helping build strong bones and inhibiting arterial calcification.

Reasons Not To Take Vitamin K With D

If it isnt clear from the title of my blog yet, Ill make it clear. I dont normally recommend combo supplements of vitamin D3 with vitamin K . I get asked all the time why my brand of D3 doesnt have K in it, and it would have been cheap and easy to put it in there but I chose not to, because of SO many reasons which Ill discuss today, but mainly because the combination can increase risk of kidney stones and may contribute to coronary artery calcifications. Its all because the two of those nutrients together add more calcium to your blood, and thats not something you want!

Sky high doses of either D3 or K can also lead to higher risk of fractures.

I know this article is going to frustrate some people, so I want it understood that I am not anti-vitamin K, in fact you can read about the virtues of K, especially for men, by to read my article entitled, Vitamin K2 A Powerful Weapon Against Prostate Cancer.But again, I dont think its necessary to put into vitamin D formulas, and this is a controversial subject.

Both D and K are easy to get without supplementation by the way. For example, vitamin D can be obtained with a walk in some sunshine and fresh air, or just sitting on your rocking chair on your porch. The sunshine provokes vitamin D synthesis in your body. And vitamin K is found in delicious salads, vegetables and fruits.

Since were talking about interactions, you might be interested in my article, Avoid Dangerous Interactions When Taking Supplements.

The Perfect Pair: Vitamins K2 And D3 Synergy Shown To Amplify Effects Of Both

19 May 2020 — Vitamins D3 and K2 each function more effectively in the presence of the other. This is according to the latest research compiled by Kappa Bioscience, manufacturer of K2 MK-7, to educate food and supplement formulators on the relationship between the two vitamins. During the launch of its recent educational series, The Perfect Pair, Kappa Bioscience explains the science behind the synergistic mechanism and its recent success in the market. While vitamins D3 and K2 have separately been widely recognized for their importance in balancing calcium for better bone and cardiovascular health, new findings make a case for the increased pairing of the vitamins on store shelves.

Ongoing research on vitamin K is revealing new ways that vitamin K acts to maintain good health. There is some evidence that vitamin K is involved in insulin metabolism, and higher intake of vitamins K1 and K2 are associated with lower risk of type 2 diabetes.16,17

Future studies will also help us to understand why K2 appears more protective against blood vessel calcification, and whether there are benefits of vitamin K that are exclusive to either K1 or K2. Leafy green vegetables provide generous amounts of vitamin K1, and getting K2 from a supplement is likely beneficial.

    Can You Get Too Much Vitamin K

    Fortunately, I could find no reported cases of vitamin K toxicity from eating too many green leafy vegetables. Unlike other fat soluble vitamins, very little vitamin K is stored. Thus, vitamin K toxicity from food isnt known to develop. On the other hand, it is always possible to overdose on vitamin K from supplements.

    How Do I Get The Vitamin D I Need

    Dont run out to the drug store to buy vitamin D pills just yet. Your body produces vitamin D when the skin is exposed to sun, and it is estimated that most people need 1,000 to 1,500 hours of sun exposure throughout the spring, summer, and fall to obtain the necessary amount of vitamin D. Vitamin D deficiency is very common and on the rise. This is mostly due to vigilant sun protection, since sunscreen with SPF 30 reduces vitamin D production by 95%. Of course, as a dermatologist I am not advocating for prolonged sun exposure, but small amounts can go a long way, as the skin produces vitamin D that can last at least twice as long the vitamin D you take in through foods or supplements. Vitamin D can also be obtained through other sources, including fatty fish , foods fortified with vitamin D , beef liver, cheese, and egg yolks. Of course, vitamin D supplements are needed for people most at risk for deficiency, including breastfed infants, older adults, people with limited sun exposure, darker skinned individuals, and overweight individuals.

    This study is expected to be completed by the end of 2018. Until that time, I will continue to enjoy my spoonful of fresh natto each morning.

    How Do You Get Enough Vitamin K2

    The very best way to prevent a vitamin K2 deficiency, is to eat a large serving of green leafy vegetables every day. Green leafy vegetables are sky high in vitamin K1. Your body will then convert vitamin K1 to vitamin K2.

    Fermented foods, like fermented soybeans, sauerkraut, and some cheeses, such as brie or gouda, can all be good sources of vitamin K2. Even though yogurt and kefir are also fermented foods, the grocery store variety contains the wrong bacteria for vitamin K2.

    Other good sources of vitamin K2 include liver and grass fed chicken eggs. Of all these sources, nothing even comes close to the amount of vitamin K2 found in natto or fermented soybeans.

    Indeed, one serving of natto has enough vitamin K2 for an entire week. Not only is natto loaded with vitamin K2, but this fermented food may also help your gut flora.

    Natto is a delicacy in Japan. Unfortunately, most Westerners cannot tolerate the taste.

    While natto certainly isnt my favorite food, I have learned to tolerate it. I have eaten a spoonful of fresh natto everyday for the last few years. You can find fresh natto at your local Asian food store.

    Who Is At Risk Of Vitamin K2 Deficiency


    Population-based studies and clinical trials have linked K-vitamin status in children to the creation of strong and healthy bones. A study published in 2008 showed that improving Vitamin-K status in children over a 2-year period resulted in stronger and denser bones. One year later, the same group of researchers showed that in healthy, pre-pubertal children, modest supplementation with Vitamin K2 MK-7 had increased activated bone forming osteocalcin.

    In a 2013 published study, researchers tested 896 blood samples collected from 110 healthy volunteers, a group composed of 42 children and 68 adults. The researchers took measurements of biomarkers reflecting the volunteers Vitamin K2 status by measuring both circulating inactive MGP and inactive osteocalcin proteins specific to heart and bone health, respectively. The researchers found that those children and adults with the most pronounced Vitamin K2 deficiency showed the highest responses to supplementation with MK-7. Children showed the largest Vitamin K2 deficiency, and accordingly may benefit from MK-7 supplementation to improve their Vitamin K2 status.

    Vitamin K2 And Polycystic Ovary Syndrome Female Fertility

    Polycystic ovary syndrome is characterized by an overproduction of certain steroids such as testosterone and DHEA sulfate .

    One randomized control trial showed that Vitamin D-K-calcium co-supplementation for 8 weeks among Vitamin D-deficient women with PCOS decreased DHEAS levels and testosterone levels.

    Vitamin K2 and its role in hormone production could both prevent and help treat polycystic ovary syndrome.

    Why Shouldnt Everyone Just Take Vitamin D Supplements

    Too much vitamin D can be harmful, including increasing fractures, falls, and kidney stones, and can be toxic by causing excessive levels of calcium. Although not proven, high vitamin D levels have been associated with prostate cancer, pancreatic cancer, and mortality. A recent study found that use of high-dose vitamin D supplements increased over a 15-year period.

    So how much is too much? For adults, toxic effects increase above 4,000 IU per day. The recommended dietary dose of vitamin D is 600 IU each day for adults 70 and younger and 800 IU each day for adults over 70. To put this into perspective, 4 ounces of cooked salmon contains approximately 600 IU of vitamin D.
