there's general info out there that zinc and calcium together will reduce absorption since magnesium would bind to calcium and nullify the absorption of the element.
people take ZMA at night for better sleep.
people also take a last-day meal of casein (or cottage cheese usually) which is pretty high in calcium.
thus, there's a problem here in nutrient timing and absorption.
also, calcium needs magnesium for absorption. so you see my dilemma here, what info and conclusion should i trust and make?
of course this all could be overthinking, but if i am going through the effort of getting ZMA and taking it, i'd like to maximize its benefits
