Viridian Vitamin K2 50ug

Viridian Vitamin K2 50ug is a premium supplement providing vitamin K2 as menaquinone-7 (MK-7) — the most bioavailable and longest-acting form of vitamin K2 — derived from fermentation of natto (fermented soybeans). MK-7 has a significantly longer biological half-life than the shorter-chain MK-4 form commonly used in supplements, remaining active in the bloodstream for days rather than hours and reaching tissues including bone and arterial walls more effectively.

Vitamin K2 plays a distinct and indispensable role from vitamin K1: while vitamin K1 (phylloquinone) is primarily involved in blood clotting mechanisms in the liver, vitamin K2 (menaquinones) is specifically required for the activation of two critical extrahepatic proteins — osteocalcin and matrix Gla protein (MGP). Osteocalcin is essential for the incorporation of calcium into bone matrix, and requires vitamin K2-dependent carboxylation to become active. MGP is the most potent known inhibitor of arterial calcification, preventing calcium from depositing in soft tissues such as arteries, where such calcification is associated with cardiovascular risk.

This makes vitamin K2 pivotal to directing calcium to where it belongs (bones and teeth) while preventing it from accumulating where it does not belong (arteries, joints, kidneys). It is therefore frequently combined with vitamin D3 in comprehensive bone and cardiovascular health supplementation, as vitamin D promotes calcium absorption while vitamin K2 ensures its appropriate distribution in the body.

Viridian's MK-7 is produced through natural fermentation and contains 100% active ingredients with no artificial additives. Suitable for vegans and produced in the UK to Viridian's strict ethical standards.
