Product Overview

  • Dietary Supplement
  • Supports Bone Health

Vitamin K2 is a more biologically active form of vitamin K extracted from a fermented Japanese soyfood called natto, a powerhouse of nutrients. Fat-soluble, it is an essential cofactor for the production of proteins that bind calcium supporting cardiovascular and bone health. Vitamin K2 is more efficient than K1 because it remains in circulation longer and is active in more tissues.

Suggested Use

1 tablet daily, preferably with a meal.

Other Ingredients

Dibasic calcium phosphate, stearic acid, colloidal silicon dioxide, modified cellulose gum, and magnesium stearate.

Contains milk and soy.

Great product!

Posted by Reviewer2684236 on May 04, 2010

I started taking vitamin K2 when I found out that I had full blown osteoporosis. After taking vitamin K2, fish oil, and vitamin D, my next bone density scan showed marked improvement.

Building Up Bones

Posted by cot477 on Oct 13, 2010

I take K2 nightly with calcium, magnesium and D3. This combination helps with aging bones AND it is mighty relaxing at bedtime and helps with sleep. ALL good! Also, I take about 20 supplements and K2 is the ONLY tablet I take... I prefer capsules for more complete absorption. This tablet is a bit big and dry and harder to swallow, but it's the only pure K2 product I could find, so I'll continue to choke it down none the less.

Vitamin K2

There are at least 2 types of Vitamin K2. This brand has menaquinone 7, which is considered the best form.
