Daily Intake on Label Confusing
Label was not clear regarding milligrams per pill. Title label stated 2000mgs per serving (of 4 pills), but “supplement label” states 4 pills is 144 mgs per serving as a 34% of daily value.
Very confusing. Not sure which metric to go by for daily intake.

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.
