Vitamin K is an essential vitamin needed for cardiovascular, bone and liver health. Vit K2 is more effective than vitamin K1, the form found in plants, for these specific health effects.
The most popular use for vit K2 is for bone health. Along with vitamin D, is essential for proper calcium absorption and usage in the bones. Vit K2 also stimulates the synthesis of proteins that regulate bone growth, and has been shown to reduce the incidence of osteoporotic fractures and improve bone quality.
It is also essential to cardiovascular health. It is an important blood clotting factor: without adequate amounts, the risk of bruising and excessive bleeding increases substantially.
