No diarrhea
My wife had severe diarrhea using a common type of magnesium, taken at doctor's recommendation. Doctor recommended this type, L-Threonate. Totally eliminated diarrhea problem.

High Quality
My husband is deficient in magnesium and these by far looked like they were of the highest quality . Not sure yet if they help him sleep better but will be purchasing them again.
