This seems to be a high quality product. However, the only problem I had was the two weeks' time it took to arrive at my house. That time line is just not acceptable.

Been taking this for 10 years
I have been taking this exact product for 10 years now. I have trouble with regularity. I take one pill every night with a full glass of water and it helps me so much. I will never use anything else for my tummy troubles.

Love this product
I love this product! I initially took it upon recommendation from my doctor to help ward off migraine headaches. While I haven't noticed any improvement with the headaches, I did notice an immediate improvement with my intestinal tract. Taking one pill daily has kept me regular like nothing else I've tried. It's amazing . I highly recommend this product for digestive health and regularity.

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.

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.

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.
