We take 100 MCG or 1 gelcap daily. We get it at the health food store. The brand we buy is called NOW.
We watched an interesting you tube video by a doctor who explained that the D3 draws the calcium into your system and then the K2 draws it into your bones. You have to take them together.
Thanks! I am off today & when I go into town I am going to look for it. Really appreciate the info.
