Big, big difference!
I was sceptical but really needed a magnesium supplement because I was experiencing leg cramps which I never had until I was in my 60s.  I am physically active, stretch etc so was unpleasantly surprised to have cramps.  I tried other magnesium products but they were inconsistent in providing relief.  THIS WORKS!!  Consistently and I am very, very pleased.  Taste is unpleasant but added in some flavored drink helps.  I got use to the taste and can easily ignore it now.  Highly, highly recommend.
