Vitamin K regulates calcium and blood clotting in the body. It helps maintain healthy teeth and bones and promotes cardiovascular health by inhibiting calcium accumulation in the arteries. It is also a powerful antioxidant. Vitamin K naturally occurs in two forms: Vitamin K1 and Vitamin K2. Clinical studies on Vitamin K2 have shown that it reduces and prevents fractures and increases bone density. Vitamin K2 is necessary to activate proteins that are involved in the utilization of calcium – both for building strong bones and inhibiting calcium accumulation in the arteries.
