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.

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.
