Heart & arterial health — Numerous studies show that vitamin K supports heart and arterial health, with higher vitamin K2 intake being correlated with a healthy cardiovascular system.
Helps maintain calcium balance — Vitamin K helps you incorporate calcium into your bones. As a part of maintaining “calcium balance”, this process helps keep calcium out of your arteries.
Vitamin K1 + two forms of K2 — It’s hard to get enough vitamin K from your diet. Super K provides vitamin K1 and two forms of bioavailable K2 to help you get enough daily vitamin K!
