Swanson, Natural Vitamin K2, 50 mcg, 30 Softgels

Bone and Cardiovascular HealthVitamin Supplements Swanson Ultra Natural Vitamin K2 (Menaquinone-7 from Natto) is the most biologically active form of vitamin K2. Everyone knows about calcium and vitamin D for bone health, but what about vitamin K2? If there’s one vitamin you should know more about, this one’s it. While vitamin K is mostly known for its involvement in blood clotting, K2 also helps to activate the proteins that regulate where calcium ends up in the body. Meaning this little-known vitamin is a powerhouse when it comes to healthy bones, and a healthy heart. Our vitamin K2 is derived from 100% natural Japanese natto (a fermented soybean product), and because the Western diet is typically low in fermented foods, it also tends to be low in K2.
