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 prevents osteoporosis, replenishes proteins in the body, promotes the formation of plasminogen, prevents cirrhosis, and enhances liver detoxification.Vitamin K2 may cause side effects such as indigestion, nausea, and diarrhea.
