Vitamin K2 for Healthy Bones and Teeth

Vitamin K2 works alongside vitamin D, calcium, and magnesium to support healthy bones and teeth. This vital nutrient:

  • Helps guide calcium into bones and teeth to build and maintain strength1
  • Supports bone-building cells to help keep calcium in bones2
  • Promotes bone density to decrease the risk of fractures3,4,5
  • Moves calcium away from soft tissues such as arteries1

Vitamin K2 – Your Secret Weapon for Anti-Aging

Just as vitamin K2 helps keep calcium where it’s needed in bones, it also assists in reducing stiffening of elastic tissues. Elastin is a key protein that gives skin and blood vessels their all-important stretchiness.

Put simply, vitamin K2 can help maintain your blood vessels and promote fresher, more youthful-looking skin by keeping wrinkles at bay!6

How Much Vitamin K2 Do You Need?

Adults need about 120 mcg of vitamin K2 daily, and there’s no known toxic dose.*

Dietary sources of vitamin K2 include the fermented soybean food natto, egg yolk, and dairy products from animals fed primarily on grass. Unfortunately, most of us don’t get enough vitamin K2 in our diet to meet our needs, especially if a diet is predominantly plant based.

MK-7 is a long-chain form of vitamin K and is the most bioavailable and bioactive form of vitamin K2. MK-7 is naturally derived from natto, a fermented bean product, and is an advanced, fat-soluble form of vitamin K.
