Vitamin K2 plays an essential role in bone metabolism and helps to reduce the risk of heart disease.  MK-7 is the most bioavailable form of Vitamin K2, which is highly beneficial, with over 20 published clinical studies confirming VitaminK2's efficacy in protecting the heart, building and maintaining strong bones.
An adult needs about 90mcg of Vitamin K2 daily to keep healthy.It is very difficult to get adequate Vitamin K2 from the displayed foods. Consequently, supplementation is needed. Vitamin K2 has two forms: MK- 4 and MK-7.MK-4 is mainly found in animal- sourced food, while MK-7 can be found in fermented cheese and natto (fermented soybeans).
With a longer side chain, MK-7 has higher stability and bioavailability. Research indicates that MK-7 stays in the human body for up to 72 hours, which is much longer than MK-4, and thus achieves greater health benefits especiallyin bone and heart health.
