"Naturally occurring vitamin K is found as either K1, which is derived from food sources such as leafy green vegetables, or K2, which is found in animal-based or fermented foods. Absorption of K1 from food can be limited due to its membrane-bound nature and the individual’s digestive and absorptive variability. Moreover, adequate consumption of foods high in K2 can be challenging. Therefore, dietary supplementation is an important option.

We developed No. 3 Bio-Available Vitamins K2 and D3 to fulfill the nutrient needs the typical diet lacks. This supplement is key for bone health, cardiovascular health and blood clotting."

    DIRECTIONS
    1 capsule in the morning

      Naturally occurring vitamin K is found as either K1 (phylloquinone), which is derived from food sources such green leafy vegetables, or K2 (menaquinones).  Menaquinones are designated as MK-n, where n denotes the length of the molecule’s aliphatic side chain. Menaquinones are synthesized by bacteria and can be obtained from animal-based and fermented foods. Structural differences between K1 and K2 impact their bioavailability and bioactivity. Furthermore, among menaquinones, menaquinone-7 (MK-7), with its longer side chain, is very hydrophobic. Compared to K1, MK-7’s physiochemical properties make it highly transportable by plasma lipoproteins, increase its extrahepatic (bones, arteries, etc.) availability, and produce its long half-life. Absorption of K1 from food can be limited due to its membrane-bound nature and the individual consumer’s digestive and absorptive variability. Moreover, adequate consumption of foods high in K2 can be challenging. Therefore, dietary supplementation is an important option. In addition, research suggests that higher levels of menaquinones are needed than were previously thought. Supplementary vitamin K can be found in three forms: synthetic K1; MK-4, which isstructurally similar to K1; and natural, long-chain MK-7. Dr. C Vitamins provides MK-7 as Vitamk7, a naturally derived and solvent-free vitamin K2 that has been obtained through a patent-granted biofermentation process of Bacillus subtilis natto cultures.
