Vitamin K for Vascular & Bone Health

Help Keep the Calcium in Your Bones—and Out of Your Arteries

As far as letter vitamins go, vitamin K is pretty special. For one, vitamin K is important to osteoblasts—the special kind of cells that keep your bones strong and healthy. And, it’s a champion of arterial health. But you have to get enough vitamin K in your diet to make a difference. This can be a problem, because vitamin K rich foods like cheese, eggs, dairy and even dark, leafy greens like spinach aren’t always on the menu. That’s why our vitamin K supplements offer clinically studied dosages of essential vitamin K.

4 Reasons to Take Vitamin K Supplements

  • Supports healthy bone density
  • Helps maintain healthy calcium balance
  • Encourages cardiovascular health
  • Easier (and sometimes healthier) than K-rich foods

Vitamin K—specifically, vitamin K2 in forms like menaquinone-4 and menaquinolone-7, is good for maintaining bone density and strength. And vitamin K also facilitates healthy arterial calcium balance by helping your body bind the mineral calcium to your bones, which keeps it out of your bloodstream.

Get to Know Vitamin K

The term “vitamin K” is somewhat of a misnomer. It should probably be “vitamins K”—plural. That’s because there’s vitamin K1 and vitamin K2. There’s also different forms of vitamin K2, called menaquinones, and there’s even sub-variants of those forms. If this sounds overwhelming, don’t worry: our vitamin K supplements offer different dosages and forms of vitamin K, depending upon your health needs.

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.
