Naturally occurring vitamin K is found primarily in two forms: K1 (phylloquinone), derived from food sources such as green leafy vegetables, and K2 (menaquinones). Menaquinones are designated as MK-n, where n denotes the length of the molecule’s aliphatic side chain. These 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. Among menaquinones, menaquinone-7 (MK-7), with its longer side chain, is very hydrophobic. Absorption of K1 from food can be limited due to its membrane-bound nature and individual digestive and absorptive variability. Moreover, adequate consumption of foods rich in K2 can be challenging. Therefore, dietary supplementation is an important option. 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, structurally similar to K1
Natural, long-chain MK-7
Total NutriCare provides MK-7 as Vitamk7, a naturally derived and solvent-free vitamin K2 obtained through a patent-granted biofermentation process of Bacillus subtilis natto cultures.
K2-D3 provide vitamin K2 as menaquinone-7 (MK-7), a highly bioavailable and bioactive form of K2. K2-D3 also features vitamin D3 (cholecalciferol), the identical form in which vitamin D is derived in the body from cholesterol and synthesized by sunlight on the skin. Historical use and numerous studies have demonstrated the efficacy of vitamin K supplements for bone and cardiovascular health.
