Promotes Bone and Cardiovascular Health, Dietary Supplement, Jarrow Formulas MK-7 is naturally made via fermentation by Bacillus subtilis subsp. natto and is 10X better absorbed then K1 from spinach. MK-7 is a longer-acting form of vitamin K vs. K1 and MK-4, and clinically proven to better support carboxylation of specific proteins needed to build bones and help protect arteries from calcium deposition.

I wanted to use vitamin k2, but i am on coumadin/warfarin for heart problems caused by a heart attack i had 16 years ago. So why are vitamin k, and particularly vitamin k2, supplements on the rise? In this review we provide the latest insights of the calcium paradox and the potential of using vitamin k to support both bone and vascular health. All but 2 trials used menaquinone-4, with the remainder using phytonadione supplements. When data from a large study of more than 16,000 women was analyzed, the results showed subjects reduced the risk of developing heart disease by 9% for every 10 micrograms of vitamin k2 taken. 60 Moreover, additional studies should be explored combining vitamin k 2 with acyclic retinoids, as this combination has also shown positive results on human hcc cell lines. The purpose of this narrative review is to summarize available evidence in the field of the synergistic interplay between vitamins d and k on bone and cardiovascular health. There is also increasing evidence fat-soluble vitamin k is needed to help build strong bones.

Additional ingredients: Many vitamin k supplements come with added vitamin d3 since these two vitamins work together synergistically. The potential mechanisms, although not yet fully understood, implicate vitamin k-dependent proteins, including matrix gla protein (Mgp) and the newly described gla-rich protein (Grp). People currently taking blood thinners, such as warfarin, should not take vitamin k supplements without seeking medical advice first. As a vitamin k inhibitor, warfarin may potentially negate these effects. A person can also purchase vitamin k as a standalone supplement or in combination with specific nutrients, such as vitamin d, calcium, or magnesium. People who are specifically concerned about their bone health may also want to take a vitamin k2 supplement, since several clinical trials have found that vitamin k supplementation can increase bone density in the lumbar spine (1 ). After conducting 13 separate trials, japanese medical authorities recommend high doses of vitamin k2 supplements to prevent and treat osteoporosis. Quickly and easy look up evidence on over 400 supplements across over 500 different health goals, outcomes, conditions, and more. Many experts recommend choosing a supplement that contains magnesium. Low levels of vitamin k impair activation of osteocalcin and decrease the activity of osteoblasts (Cells important for building bone). Consuming vegetables at the same time as some fat improves phylloquinone absorption from the vegetables, but the amount absorbed is still lower than that from oils.

Phylloquinone is found at high concentrations in green leafy vegetables and certain plant oils, while most menaquinones are usually found in animal livers and fermented foods. It is my belief that if i can get some of this bad cholesterol out of my arteries i might be able to tolerate a low dose of k2 mk4 which i still feel i need because of the factor 2 vitamin k deficiency. For vitamin d3 and k2, the recommended daily intake (Rdi) depends on a wide range of variables, such as age, sex and the particular state of health of each individual. Unfortunately, circulating markers of vitamin k concentrations and vitamin k-dependent proteins were not taken into account to get a better mechanistic understanding. Most clinical trials studied vitamin d and k supplementation with bone health in postmenopausal women. These limited studies indicate that joint supplementation might be beneficial for cardiovascular health. Combining vitamin k 2 with an ace inhibitor (Perindopril) has shown synergistic effects on hcc recurrence and survival, and thus this combination should also be further explored. Vitamin k 1: Observational studies have found a relationship between phylloquinone (Vitamin k 1) and age-related bone loss (Osteoporosis). Q: Does vitamin k2 interact with vitamin d3? Researchers believe vitamin k2 may work in concert with vitamins a and d in keeping teeth strong and free of cavities. Nevertheless, further studies are needed to prove that supplementing with vitamin k actually causes these improvements in heart health.

For example, the incidence of vertebral fractures was inversely correlated with lumbar bmd and plasma phylloquinone in a four-year prospective study that included 379 japanese women ages 30-88 years. Some fruits, such as avocados, kiwifruit and grapes, also contain vitamin k. Though your body is quite capable of absorbing vitamin k in any of it’s forms, vitamin k that is found in vegetables is thought to be absorbed less efficiently than vitamin k2 from a supplement. Recent evidence, as outlined in detail above, suggests that vitamin k is an important factor in bone and vasculature in ckd patients and post-menopausal women, and that it’s role may be overlooked. K complete is a great option to cover all of our bases for vitamin k requirements. Are breast-fed infants vitamin k deficient? The pharmacology and management of the vitamin k antagonists: The seventh accp conference on antithrombotic and thrombolytic therapy. Furthermore, in individuals with inadequate calcium intake, the supplementation plan seems to be beneficial in reducing fragility fractures especially in osteoporotic women (86, 107). There are two main forms of vitamin k: Phylloquinone (Vitamin k1) which is found in green leafy vegetables and makes up about 90% of the vitamin k in a typical western diet; and menaquinones (Vitamins k2), which make up about 10% of western vitamin k consumption and can be synthesized in the gut by microflora.

This supplement is gluten free, vegetarian, and kosher. This means that a vitaminized oil can influence vitamin k-dependent proteins within multiple weeks. In this systematic review and meta-analysis, we have shown that supplementation with phytonadione and menaquinone, particularly menaquinone-4, is associated with increased bmd and reduced fracture incidence. Suddenly increasing or decreasing vitamin k intake can interfere with the effects of these drugs. Other fermented foods, such as cheese, also contain menaquinones. An increasing amount of randomized controlled trials have demonstrated the combined effects of vitamins d and k on postmenopausal osteoporosis mostly pursued in japan with a study duration between 8 weeks and 3 years (Table 1). Background observational and some experimental data suggest that low intake of vitamin k may be associated with an increased risk of fracture.

Vitamin d in high doses for long periods of time without adequate vitamin a, k2, magnesium and the other cofactors may cause some issues. Summary: It is best to incorporate a variety of food sources of both vitamin k1 and k2 in your diet to obtain the health benefits that these vitamins offer.

There appears to be some protection from fracture risks by calcium supplements, but it’s safety is still not sufficiently established. A 3-year study in 244 postmenopausal women found that those taking vitamin k2 supplements had much slower decreases in age-related bone mineral density. Also, if this is the vitamin d2 form, just throw it away. Vitamin k has been promoted in supplement form with claims it can slow tumor growth; however, no good medical evidence supports such claims.

However, adequate dietary calcium (With or without supplementation) does not guarantee the optimal delivery of calcium to bone. Although i think it’s insane to put vitamin a in the same category as street drugs! Collectively, these data imply that vitamin k could serve as complementary nutrient to calcium (And vitamin d) to protect from increased risk for vascular calcification thereby allowing more safe treatment of osteoporosis. The vitamin k cycle allows a small amount of vitamin k to be reused many times for protein carboxylation, thus decreasing the dietary requirement. Osteocalcin (Also known as bone gla protein) is synthesized by osteoblasts (Bone-forming cells); the synthesis of osteocalcin is regulated by the active form of vitamin d, 1,25-dihydroxyvitamin d (Calcitriol). The benefit of vitamin k on bone is thought to be unrelated to increasing bmd but rather increasing bone strength.

Multiple scientific studies on postmenopausal women suggest that combined d3 / k2 supplements can improve bone density, possibly reducing the risk of fractures as you get older. Does taking a laxative interfere with the absorption of vitamins or minerals? Although supplementation with phylloquinone decreased ucoc levels in all five studies, only one study reported an effect of supplemental phylloquinone on bmd. After 10 weeks, treatment with vitamin k had normalized blood glucose and reduced symptoms of anxiety and depression. Both forms of vitamin k are essential for blood clotting and bone health. The anticoagulant drug warfarin acts as a vitamin k antagonist by inhibiting vkor activity, hence preventing vitamin k recycling (See coagulation). Overviews of the other fat-soluble vitamins, minerals, and water-soluble vitamins are available elsewhere. Nevertheless, present dietary reference values (Drv) for vitamin k are exclusively based on phylloquinone and it’s function for coagulation. It reduces the body’s absorption of dietary fat and in doing so, it can also reduce the absorption of fat-soluble vitamins, such as vitamin k. If you follow our advice, you can get the most out of your vitamin d3 and k2 supplement combination.

Jho’k has a major ownership interest in cardiotabs, and is also founder and chief medical officer for this nutriceutical company that has products containing vitamin k.

My suggestion is to get a lot of summer time sun exposure and rely of d3 supplements during winter and spring. Reported no correlation between responses in a food frequency questionnaire and plasma phylloquinone. Menaquinones have also been shown to be involved in the active transport of molecules across the cell membrane.
