Vitamin K isn’t one vitamin, it’s a family of fat-soluble vitamins with similar chemical structures but different metabolic properties. K2 belongs to a group of vitamin K compounds called menaquinones, which show greater bioactivity when compared to K1, the ordinary supplemental form. K2 is absorbed more completely, remains in the body longer and delivers more benefits for bones, blood vessels and other soft tissues, Helps support bone health and soft tissue elasticity, Highly effective delivery of vitamin K to bone and soft tissue, Helps support calcium metabolism for maintenance of healthy bone.
Vitamin k is a group of structurally similar, fat-soluble vitamins found in foods and in dietary supplements. K3 is a synthetic version of k vitamins and is potentially harmful to the body and should be avoided. As more is discovered about the powerful combination of vitamins d and k, it gives a renewed reason to eat a healthy diet including a variety of foods such as vegetables and fermented dairy for bone and cardiovascular health. Overall, the available studies have been somewhat inconsistent, but the current evidence was convincing enough for the european food safety authority to conclude that vitamin k is directly involved in the maintenance of normal bone health. Certain hard and soft cheeses are also good sources of vitamin k2, in the form of mk-8 and mk-9, additionally, a recent study discovered several pork products contain vitamin k2 as mk-10 and mk-11. Consequently, excess vitamin d diminishes the ability of vitamin k-dependent proteins to function properly, to stimulate bone mineralization, and to inhibit soft tissue calcification. Conclusions this systematic review suggests that supplementation with phytonadione and menaquinone-4 reduces bone loss.

Many experts believe vitamin k activates proteins required for bone growth and development. It is important to expand the knowledge base regarding the health effects of menaquinones and the distribution of mks in the food supply. Undercarboxylation of osteocalcin in human bone and serum has been linked to poor vitamin k status. Vitamin k 1: Observational studies have found a relationship between phylloquinone (Vitamin k 1) and age-related bone loss (Osteoporosis). Perhaps because of it’s limited ability to store vitamin k, the body recycles it through a process called the vitamin k-epoxide cycle (Figure 2). Of the 10 menaquinone forms, mk-4 (With a shorter side chain) and mk-7 (With a longer side chain) are the most important to bone health. If you decide to add more vitamin k-containing foods to your diet, be sure to let your doctor know so that he can check your blood and alter your warfarin dose if necessary.
Despite positive outcomes of calcium supplementation, a risk for cardiovascular risk events may exist in specific population. An outstanding source of nourishment for both your blood and bones, each convenient tablet delivers 100 mcg of vitamin k. Clinical guidelines consider a cumulative calcium intake from foods and supplements that does not exceed 2,000 to 2,500 mg/d, as defined by national academy of medicine, as safe for cardiovascular disease outcome (105, 106). However, higher vitamin k intakes were not associated with lower cvd mortality in a prospective study that followed 7,216 older adults at risk for developing cvd. It may be thought of as the plant form of vitamin k. You may have thinner blood, but you may also increase arterial calcification with the medically-induced vitamin k deficiency. Pilkey et al 70 demonstrated that 29% of patients with haemodialysis have coexisting subclinical vitamin k deficiency. Menaquinones (Vitamin k 2) are primarily of microbial origins and thus commonly found in fermented foods, such as cheese, curds, and natto (Fermented soybeans). D3 helps your body absorb the all-important calcium, and vitamin k2 (As mk-7, the form of k2 with the highest bioavailability) directs the calcium to your bones instead of your joints and arteries, where too much calcium could be problematic.
However, that rda, is thought to be insufficient, as it does not include the vitamin k requirements for other bodily tissues. However, you would need to have an extremely high consumption of these foods in order to get a sufficient amount of vitamin k2, as natto and/or kimchi remains unpopular in the western world, supplementation with additional vitamin k2 is the optimal alternative to getting an adequate amount of vitamin k into your system. Because a synthetic form of vitamin k, vitamin k 3 (Menadione), may be toxic by interfering with the function of glutathione, it is no longer used to treat vitamin k deficiency. The use of calcium supplements has been widely advised due to their assumed ability to support bone health and bmd (7, 8). There are five variants of this vitamin in existence. Gla-rich protein is a novel vitamin k-dependent protein present in serum that accumulates at sites of pathological calcifications. Both vitamin d and vitamin k contribute to bone density. Unlike the safe natural forms of vitamin k 1 and vitamin k 2 and their various isomers, a synthetic form of vitamin k, vitamin k 3 (Menadione), is demonstrably toxic at high levels. Food sources of vitamin k2 vary by subtype. Given your condition, i would check with your doctor before you make any changes to your supplement routine.

As a dietitian, when i used to counsel individuals, there were several occasions when my clients brought in shopping baskets filled with supplements. Maternally administered antenatal vitamin k1: Effect on neonatal prothrombin activity, partial thromboplastin time, and intra-ventricular hemorrhage.

However, vitamin k-2 may also protect against certain forms of cancer and heart disease. Further, potential interaction between vitamin k status and polymorphisms of the vitamin d receptors was investigated. As outlined, vitamin k has a role in healthy bone formation, while at the same time it provides protection against ectopic calcification, especially in the cardiovascular system. Western diet does not provide sufficient vitamin k to activate all oc and mgp that is produced (21, 22). The vitamin k cycle allows a small amount of vitamin k to be reused many times for protein carboxylation, thus decreasing the dietary requirement. No increased risk was observed in the groups low in 1 vitamin only. Animal and human studies suggest that optimal concentrations of both vitamin d and vitamin k are beneficial for bone and cardiovascular health as supported by genetic, molecular, cellular, and human studies. In experimental models, the exploration of the interaction between vitamins d and k on bone health is ongoing for decades and a fair amount of literature is available. When menopausal women took k2 supplements over a three-year period, they experienced reduced rates of declining bone mineral density in comparison to women who took no supplements.
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. Although vitamin d3 and k2 supplements are generally considered to be safe when taken together in the recommended doses, they are not free from contraindications. To get back, i started taking calcium/magnesium/d3 in the morning (Calcium supplements need to be taken a few hours before strontium to avoid it interfering and two nature’s life strontium/d3/k2 at night. Supplementation of vitamin k in pregnant women receiving anticonvulsant therapy prevents neonatal vitamin k deficiency. More evidence on the combined role of vitamin k antagonist use and vitamin d on bone and cardiovascular health is urgently needed. In phylloquinone, vitamin k1, the side chain has four isoprenoid residues or 5-carbon units, the last three of which are saturated (Don’t worry, you will not be tested on this). Besides bone health, also, the interaction between vitamins d and k with regard to cardiovascular health receives growing research interest.
The extra carboxyl group in gla made clear that vitamin k plays a role in a carboxylation reaction during which glu is converted into gla. A deficiency of vitamin k entails the risk of soft tissue calcification and vascular disease. Nature made is about as basic as you can get in a vitamin k2 supplement. Vitamin k2 is one form of vitamin k, a relatively recently discovered vitamin that contributes to bone strength, blood clotting, and cardiovascular health. On the bone page, we offer a summary of the research on the bone health benefits of the vitamin k family. They can get to the root cause of the issue and possibly even identify if you have any genetic predisposition for poorly metabolizing b vitamins or anything else. What was once a vitamin recognized mainly for promoting healthy blood clotting is now understood to also promote bone and cardiovascular system health. 11 However, less than 20% of vitamin k1 in food is absorbed by the human body. Further, the use of cholesterol-lowering medications (Like cholestyramine and colestipol), as well as orlistat, mineral oil, and the fat substitute, olestra, which interfere with fat absorption, may affect the absorption of fat-soluble vitamins, including vitamin k. In the liver, vitamin d is hydroxylated to 25(Oh)d, the main circulating vitamin d metabolite that is measured to assess and classify vitamin d status.
So, for some, supplementation may be helpful. Having looked at the process and patents for making mk-7, i personally feel that none of the mk-7 forms on the market are truly natural because of the complex steps required to make the product and also because the finished mk-7 is so far removed from nature. I want to be clear, just because these are the supplements that my doctor approved of, it might not be the best for you! It is rich in vitamin k2 from what i understand. Genetic, molecular, cellular, and human evidence support that optimal concentrations of both vitamin d and vitamin k are beneficial for bone and cardiovascular health. 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 ). This review presents an overview of what is known of the role of vitamin k in brain function. Research has shown that vitamin k is an anticalcification, anticancer, bone-forming and insulin-sensitising molecule. Taking a vitamin d3 supplement without k2 can have disastrous effect, as vitamin d creates need for vitamin k2 in the body. Thus, despite the relative benefit of calcium supplementation for bone, calcium supplements became controversial because of a possibly increased cardiovascular risk. This study shows the differential effects of vitamin k and vitamin d supplementation on calcium balance in young rats fed with a normal or low calcium diet.
It can be challenging to find vitamin d3 and k2 supplements for vegans and vegetarians. Many vitamin k2 supplements on the market are produced using soybeans. Mechanism of coumarin action: Significance of vitamin k epoxide reductase inhibition.
