Excellent Supplement

This product really works and cured my leg cramp problems. It was recommended to me by the pharmacist at my Walmart. It is the highest quality and purity. it's a necessary supplement that most people need for bone, muscle and nerve health.

Not for me

Recommended to buy this “oxide”. However, when reviewed, this version of magnesium causes stomach looseness. Others, do not. Returned it after delivery.

I wanted to write a review because I think this is a very good product. Every other magnesium supplement I've used has resulted in stomach issues. Mag-Ox helps with muscle knots and pain without the stomach issues. I've used it for several years now. Good product!
