M.C.H.C. caps

Posted by Reviewer1789384 on May 30, 2011

I've taken this product for many years, after my wellness doctor advised me to do so. I believe taking these and a number of other vitamins and minerals have kept me in good shape to stay active in my older years.

Helps the bones as I can't tolerate the hard pill calcium that they sell at wal-mart.

Excellent Calcium Product

This is a wonderful product. I had my doctor look at the ingredients and he said they are as good or better than the ones they compound themselves!

Your body will readily absorb this...

Minerals have to be small enough to be absorbed and that's why they created this product. It's absorbable! My fingernails improve on this...
