Vitamin K2 (menacinone) is a type of vitamin K. The vitamin can contribute to normal blood clotting. Therefore, a lack of vitamin K can lead to unwanted bleeding. Another benefit to the health of this vitamin is that it contributes to the care/maintenance of normal bones. Vitamin K can be found in many foods such as milk, spinach, cabbage and other green vegetables. Vitamin K is a fat-soluble vitamin. Fat-soluble vitamins are stored in the body’s own fat tissue for a longer period of time and the concentration could potentially increase to dangerous levels. Therefore, vitamin A, D, E and K are only found in small amounts. There are two types of vitamin K2, short-chain and long-chain menachinones. MK-4 (Menachinone 4) is an example of a short chain. The biological half-life of MK-4 is about 1-1.5 hours. This is significantly shorter than long-chain menaquinones. Long-chain menaquinones such as the MK-7 and MK-9 have a biological half-lives of several days. Our vitamin K2 MK-7 powder is extracted from natto and the source is Bacillus subtilis natto. This is a natural source of vitamin K2 and currently the most popular on the market. Please note that our vitamin K2 MK-7 has been extracted from a soy source, and as such naturally contains soy.
