Hi There,
It was suggested that Chelated Magnesium is the type of Magnesium to take. I heard that magnesium can result in gastro intestinal issues (diarriah and cramps) but when taking the Chelated Magnesium it has been known to illuminate that typical side effect.
My son has Tourette's and I'm a Mo that is trying my best to find natural ways to help Him.
I hope this helps.
