Product Description

Vitamin K2, also known as menaquinone 7, is a fat-soluble vitamin, commonly referred to as MK. Vitamin K2 is generally subdivided into the short-chain menaquinones (with MK-4 as the most important member) and the long-chain menaquinones, of which MK-7, MK-8 and MK-9 are nutritionally the most recognized. The activity of vitamin K2 is related to the length of the side chain, the longer the side chain, the better the absorption, the higher the biological activity, and the longer the presence in the blood.

Vitamin K2 (Menaquinones, MK) plays an important role in bone and cardiovascular health. The activity of vitamin K2 is related to the length of the side chain. The longer the side chain, the better the absorption, the higher the biological activity, and the longer the time in the blood. Vitamin K2 (MK-7) is the most unique of the vitamin K2 family with highest bioavailability. It has a long half-life in the blood after oral intake, so it can play its benefits in a longer period of time.

 

Vitamin K2, especially the long-chain vitamin K2 in the form of MK-7, is recognized as a high-quality natural vitamin K2.In 2008,the European Food Safety Authority(EFSA) has published a positive scientific opinion on vitamin K2, MK-7 from natto as a dietarysupplement and food ingredient. In 2009, the European Food Safety Authority gave a positive evaluation to the claim of vitamin K2 to reduce bone loss and improve bone integrity. Natto-derived vitamin K2 (MK-7) has been approved as Novel food.
