We're always looking for ingredient forms that give your body more to work with, and magnesium was a clear opportunity. ATAMg® (magnesium acetyltaurinate) is a highly bioavailable form of magnesium that supports brain and neurological function.* We pair it with magnesium bisglycinate and malate for a total of 150 mg of magnesium per serving.
