Do we need more than the recommended daily amount in order to get major benefits to the immune system? Like would the amount in a multi be good enough?
I believe minimum recomended zinc for adults is 11 mg zinc
I take about twice that...but I also take querecetin
if you take a lot of zinc you might think about copper
some zincs have a small amount of copper.
lots for you to read up on
depends how long you take it and what else you take..
im not a doctor
what you eat also is relevant vitamins are in food and different people eat different foods...
