Thank you so much for your help. I love this forum and learning new things. You were right. It is Magnesium Oxide. I will change that as soon as I can. I have read that before about the D3. That is good to know because that could solve my problems if I am taking too much calcium because I think my problem is arterial plaque which causes poor circulation. Do you know of another way to clean that out? That is what I was hoping to do with the Nattokinase.
