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 for your bones!

Posted by Reviewer3060686 on Feb 05, 2011

Excellent quality. I may repurchase this particular brand, or try others at iHerb. K2 is a necessity if you have concerns about joint flexibility- I highly recommend it!

You ran out of Life Extension vitamin K so I tried this one. It's good. But when I use this up I'll go back to the Life Extension brand. I like the mixture of three types of vitamin K in it.

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.
