> I read an arcle that zinc could be neruotoxic if too much is taken. It said that zinc was responcable for neurotoxicity in certain situations. Do you know if this is true. Should high doses not be taken, or not at all ???

> LinkadgeThe article references free zinc, i.e. water-soluble Zn++ ions. Your body is perfectly capable of managing zinc from oral intake, because zinc only enters the body via very specific zinc transporters (four types identified so far), and once across the gut wall, there the zinc is met by carrier proteins called metalothioneins. That makes the zinc ions bound. There is virtually zero free zinc ever, anywhere in the body, except under very gross disturbances of metabolic processes.
I do not have the slightest hesitation in recommending zinc supplements to anyone, especially depressives.
