Talk:Magnesium (medical use)

bioavailability in food

In the area of nutrition supplements, Magnesium oxide is infamous for being very cheap and common but having extremely low bioavailability, and thus nearly useless for nutrient purposes. Most other Magn supplement chemical forms are supposed to be much more bioavailable, at about 30%. What form is Magnesium in, in common foods, and what is the bioavailability in various foods -- is there significant variation in this?-71.174.180.38 (talk) 18:45, 6 September 2016 (UTC)
