Description
Vitamin K2 (Menaquinone-7 or MK-7) is a fat-soluble vitamin essential for bone and cardiovascular health, as well as blood clotting. It functions by activating proteins, such as osteocalcin and matrix Gla protein (MGP), that are involved in calcium regulation within the body. MK-7 directs calcium to bones, promoting bone density and strength, and inhibits calcium deposition in arteries, reducing arterial calcification. Sourced primarily through bacterial fermentation, MK-7 boasts superior bioavailability and a longer half-life compared to other forms of Vitamin K. While generally safe, potential interactions with anticoagulants warrant careful monitoring, and high doses may rarely cause mild gastrointestinal upset.
