This magnesium works great! I am very pleased with it's consistent performance. I have used it for about 2 years. Even though magnesium oxide is not supposed to be the best absorbing, useful, etc, I tried the GNC super magnesium with the supposed "best" magnesium forms but it DID NOT have good, consistent results. I am switching back to this magnesium 500. It is cheaper, lasts longer & you only have to take one as compared to the super magnesium that directs you to take 2 daily but I had to take 4 for any results. Don't waste your money on the super. This will work great!!

Many Benefits
I started using this product several years ago after I had 1/3 of my colon removed, I take one daily. It aids in keeping my digestive tract running smoothly. At one time I substituted a Calcium and Magnesium combo capsule and I had problems with constipation almost immediately. When I went back to the Magnesium 500, everything was back to normal. I love this product!!

Used to stop night leg cramps
I started using one capsule per day in February for chronic serious nightly leg cramping. No more cramps until last Friday when I missed a dose! I will not miss any more! Great product.

Kind of a miracle
I have had chronic issues with constipation. I have tried many different products to help my cause, and finally through my research online I read someone singing the praises of Magnesium OXIDE. I have been taking 1 pill at night before bed and waking up ready to go. I feel so much better. I would recommend this to anyone, and at the price it is worth a shot.

Magnesium 500
I decided to order online since the GNC store in my area very seldom has the Magnesium 500 when I need it. I received my order in a very timely fashion and actually paid less than when I bought them at the store. (Even with the Canadian $ exchange rate!!!). I will order them online again.

Works very well.
I have been using GNC Magnesium for 15 years to replace magnesium that is depleted by my immune suppression medication after a liver transplant. I have found that it works very well.

Worst Magnesium
GNC's Magnesium is made with Magnesium Oxide, which is one of the worst forms of Magnesium you could possibly take. I purchased it because they had stopped carrying the Drs. Best in their stores around me. It made me extremely sick for 3 months, before my doctors finally figured it out. Very Disappointed with GNC.
