What Is Super K?
Super K provides three different kinds of vitamin K that support arterial health: K1 and two types of K2, MK-7 and MK-4. Although leafy green vegetables contain vitamin K1 and vitamin K2 is found in some types of dairy products, it’s difficult to get enough vitamin K through diet alone.
Support your heart health and arterial function with a vitamin that’s hard to get enough of from diet alone.

Why Should I Supplement With Vitamin K?
- Vitamin K is good for bone, heart and arterial health.
- It’s difficult to get sufficient vitamin K from food alone
- Choose our high-dose vitamin K1 and K2 combo formula, or take vitamin K2 as a standalone in varying dosages.
Vitamin K helps maintain your body’s calcium balance, which affects several systems including arterial health and bone structure. But it’s hard to get sufficient vitamin K from food. So if you’re trying to maintain arterial health, a vitamin K supplement is a good idea.
