"Generic high potency magmesium supplement"
12 October 2016cremeburmese

originally posted on ebay.com

As a sufferer of nocturnal cramp, magnesium supplement is part of the normal medication protocol. My GP recommended up to 2 tablets 3 times a day. It is the difference between a good night sleep or broken sleep. This brand is significantly cheaper than the original manufacturer including postage.

Best magnesium in the market!

I use Mag-Sup tablets for a magnesium deficiency I have. These are the best and highest dose tablets I can get. Ive tried others and always come back to these. Best value in a 250pack too.

Nightly leg cramps gone
29 April 2020

After medical advice about having leg cramps at night, I was told that I had a magnesium deficiency. I tried several proprietary over-the-counter brands, and strengths, with no success, when a friend recommended Mag-Sup 500mg. It as an almost instant success, and I've been taking them ever since.
