Best Calcium!

Posted by Reviewer1811241 on Sep 13, 2010

This product was recommended by my naturopath for osteoporosis over another one recommended by a wellness chiropractor because of the added magnesium plus other nutrients. He felt it added overall to new bone growth than any other product available and since he has improved my health in other areas,I believe him.I am completely satisfied.
