Vitamin K or phylloquinone, is a fat-soluble vitamin best known for its important function in the biological activity of several blood coagulation factors. Recent research has also shown a role for vitamin K in bone health. Vitamin K plays a key role in the synthesis of the bone proteins osteocalcin and matrix Gla-protein, which are involved in calcium and bone metabolism.

iHerb Customer Reviews
I bought this vitamin because there is not enough of vit. K in my multivitamins in order to balance it out. After having taken it for a month I noticed my teeth feel cleener and there is no plaque when I floss. Today the dentist thought I had my teeth cleaned recently. My gums no longer bleed when I floss or brush, but I'm also taking a one a day multivitamin + minerals and extra vit. C. I'm very happy with the result and will definitly repurchase. I'm thinking to add vit K2 in the near future. Thanks for the quick delivery.
I had my first normal menstrual period with the product i.e bleeding lasted less than 7 days and the whole process was painless.
good for the price

Stopping dot hemorrhages
Posted by Reviewer2095408 on Jun 05, 2013
Contrary to what's said medically, 500 to 1000mcg of K1 a day works uncomparably better for me than K-2(neither 1000mcg of MK-4 or 90mcg of MK-7 was effective) in stopping dot hemorrhages that kept popping up in everyday life. (I had those weird red spots long before I started taking 100 to 200mg aspirin a day for a reason. I had to raise the dose of K1 after I started aspirin, but it's still helping.) It seems to be doing good to my teeth, too.
