Wiley's Finest Vitamin K2 & D3 60 Softgels

Wiley's Finest Vitamin K2 is a premium supplement providing vitamin K2 in its most bioavailable and biologically active form, MK-7 (menaquinone-7), derived from natural fermentation. Vitamin K2 MK-7 has a significantly longer half-life in the body compared to the MK-4 form, providing sustained activity over 24 hours and superior accumulation in extra-hepatic tissues, particularly bones and blood vessel walls, where its protective effects are most needed.

Vitamin K2 plays a number of critical roles in the body that are distinct from those of vitamin K1 (found in leafy green vegetables), despite the two sharing some biochemical pathways. While K1 is primarily involved in blood coagulation, K2 is uniquely important for the regulation of calcium metabolism throughout the body. It activates two key proteins, osteocalcin, which incorporates calcium into bone matrix, and matrix GLA protein (MGP), which prevents calcium from depositing in soft tissues including arterial walls, ensuring that calcium goes where it is needed (bones and teeth) and does not accumulate where it is harmful (arteries and other soft tissues).

This calcium-directing action of vitamin K2 has significant implications for both bone and cardiovascular health. Adequate K2 intake is associated with greater bone mineral density, reduced risk of fractures, and slower progression of osteoporosis. Simultaneously, K2 supplementation has been shown in several well-designed clinical trials to reduce arterial stiffness and slow the progression of coronary artery calcification, making it a uniquely important nutrient for long-term cardiovascular wellness.

The synergy between vitamin K2 and vitamin D3 is an important consideration for supplement users. Vitamin D promotes calcium absorption from the gut, and K2 ensures that this additional calcium is directed appropriately to bones rather than contributing to arterial calcification. Many experts recommend combining these two nutrients, and this formula is designed to complement supplemental D3 intake effectively.

Wiley's Finest Vitamin K2 softgels contain the biologically natural all-trans form of MK-7, which is more active than the cis forms. Each softgel is tested for identity, purity, and potency to ensure consistent quality. This product is an essential supplement for those concerned about bone density, cardiovascular calcification, or anyone taking supplemental vitamin D3.
