I have been concerned about people taking huge amounts of zinc recommended by providers that virtually know nothing about nutritional supplements. Physicians are not required to study nutrition as part of their curriculum so people must be careful about jumping on the bandwagon. When someone is fighting active infection, zinc can be increased - but for healthy people, 15mg every couple of days is fine. Also, any zinc supplement should also contain copper to balance the zinc. Too much zinc can lead to depletion of copper. That can lead to anemic like symptomology. People with a history of anemia must also be cautious taking large amounts of zinc.
