I read somewhere that if calcium is taken at the same time as zinc or iron, the body will absorb calcium ahead of the other two nutrients.
not sure how true this is & whether it means that the zinc or iron absorption is reduced?
....if the calcium thing is applicable to your situation, then look in to this further for yourself.
....so if do you do supplement with calcium (which i do not) or eat a high calcium food, then you may want to keep it away from your zinc (a min of a couple of hours apart at a guess).
