Vitamin K is vital for bone and vascular health, but it’s difficult to absorb from our diet. We offer multiple versions of this essential vitamin. Let’s compare our most popular formulas to see which best meets your needs.

Vitamin K and K Blends

Our Super K formula has three forms of K: vitamin K1 as well as two forms of K2. The two K2 forms (MK-4 and MK-7) have complementary nutritional properties — MK-4 is rapidly absorbed, and MK-7 absorbs more slowly. If you only need a little MK-7, our Low Dose Vitamin K2 includes 45 mcg of K.

What is vitamin K?

Vitamin K is an essential nutrient for optimal health, benefitting your heart and bones. Foods rich in vitamin K include spinach, kale, broccoli, lettuce, blueberries, figs, cheese, eggs and soybeans. However, even the healthiest diets don't provide all the vitamin K your body needs, so a high-quality supplement is important.

What does vitamin K do?

Without enough vitamin K, your bones wouldn't be quite O-"K!" That's because your body needs vitamin K to produce prothrombin, an essential protein that helps support bone metabolism. Vitamin K also keeps bones strong by supporting calcium metabolism and promoting overall bone density.

How much vitamin K should I take?

Before incorporating a vitamin K supplement into your wellness routine, first speak with your doctor about your individual health goals and also consider taking a vitamin K1 blood test to assess your current levels. The recommended intake for vitamin K depends on your age and gender, but an all-in-one, supercharged vitamin K supplement delivers 2,000 mcg of vitamin K1, 1,500 mcg of K2 as well as trace amounts of MK-6, MK-7 and MK-9. No matter what vitamin K supplement you choose, make sure to follow the dosage on the bottle and not take more than what is recommended.
