I wasn't sure this would be any good given the price it was offered at, I was sorely mistaken, it has worked better than my regular magnesium from a leading brand on the high street. It's fast effective and best of all great quality. I can't wait to see the effects in a months time. I am most certainly moving my regular brand aside for this. Completely converting my supplement brands over to this one. No cost cutting has been applied here, that is plainly obvious, by the quick results and continued improvement. I am so happy. All my friends who rely on magnesium are going to try this too, great for sleep regulation, craving (most chocolate cravings are do to magnesium deficiency) and muscle recovery. They are going to be so happy when they see all the positive results.
