Best Vitamin K2 Supplements: Why It Matters and Which Forms Are Best Absorbed
What Vitamin K2 Does: Vitamin K2 is part of the vitamin K family, a group of fat-soluble nutrients needed for normal blood clotting and bone health. K2 refers to compounds called menaquinones, which range from MK-4 through MK-13. Two forms commonly found in supplements are MK-4 and MK-7. Vitamin K helps activate proteins involved in bone metabolism and other important functions in the body. ( Office of Dietary Supplements ) Vitamin K2 has attracted attention because of its possible role in helping the body use calcium properly. Research continues into whether getting enough vitamin K may support bone strength and cardiovascular health. However, evidence that K2 supplements can prevent osteoporosis or heart disease is not strong enough to treat them as proven therapies. ( Office of Dietary Supplements )
