Useful Product !

Good product. I have started 1 Tablet a day, the results are there to be seen, though slow. In another 10 days, i will increase to 2 tablets/day. My teeth still aching though.

Quick muscle tension relief

Posted by 5319322460159271439 on Sep 15, 2016

I have taken a few different brands of magnesium for muscle tension from stress over the years and need large doses to feel comfortable, but this causes explosive GI side effects which is enough to make me stop taking it and put up with the pain. I get no side effects at all with this brand if I spread the doses out over 2-3 meal times and I think partly because of this, it works amazingly well. I usually only remember to take a tablet with breakfast and dinner and it definitely makes a big difference for several hours. I won't be switching from this brand and hope it continues to be available.
