Vitamin K is an “essential” vitamin—your body cannot make vitamin K on its own. And we need it: vitamin K helps with everything from arterial health to bone structure. But it’s hard to get sufficient vitamin K from food. Super K provides 180 mcg of vitamin K2 (MK-7); 1,000 mcg of vitamin K2 (MK-4); and 2,000 mcg of vitamin K1. This once-daily softgel is a great way to ensure you get your daily dose of healthy vitamin K. Gluten-free, non-GMO, manufactured in the USA.

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!
