iHerb Customer Reviews

No blood tests done

Posted by iHerb Customer on October 6 2012 | Verified Purchase

I was not expecting any miracle, and none happened. I am just taking MK-4 and MK-7 to prevent calcification of arteries and to strenghten my bones. It is too early to say whether it works or no. See me in 30 years. What can I say is that the product was well packed and the pills are very tiny. I've been taking NOW K2 and Jarrow K2 in the past, and would consider all three products of the same quality. Oil based softgel with both MK-4 and MK-7 in generous doses.

Thanks for your feedback!

K2 is important.

this has the correct amounts of menaquinone-7 and menaquinone-4, which most other products don't. Life Extension is one of the best brands out there, and you can trust what they state on the bottles.

Thanks for your feedback!

They revised the ingredients

Posted by iHerb Customer on August 10 2012 | Verified Purchase

I like the product - this is the only Vit K product I found that reduced little bleedings under my epidermis that turn into moles. (MK-7 alone and MK-4 alone without K1 didn't work.) 4 stars is to warn that the ingredients have been revised in Dec, 2011. They put in less MCT and use olive oil now. "This product contains no (allergens, etc.)" statement has been removed, too. See http://www.lef.org/Vitamins-Supplements/Item01224/Super-K-with-Advanced-K2-Complex.html

Thanks for your feedback!

excellent for bones and teeth

This product has the proper amounts of the different versions of vitamin K. I take it with calcium, magnesium and zinc. The first week I started taking it, one tooth that had been hurting for a while stopped hurting.

Thanks for your feedback!
