The product helps a lot

My father has strong osteoporosis. One year after taking Vitamin K2 his doctor could not believe how much his status had improved. Carlson labs Vitamin K2 really helped him to improve his quality of life!

I have not had a bone density test since starting on this K2 and I understand that it is very helpful so I will update my review as soon as I get a bone density which will most likely not be until the fall......

Thanks for your feedback!

Good For Teeth

Besides putting calcium where it belongs, there is evidence that K2, MK4 can re-enamelize teeth.

Thanks for your feedback!

Vitamin K2

Posted by iHerb Customer on November 17 2014 | Verified Purchase

This is one of the few places I can get Vitamin K2 in this dose. I take 3 tablets 3 times a day for my osteoporosis. The product arrived in a couple of days with the free shipping.
