Zinc, if taken at high concentrations over a long period of time, can deprive the body of copper, which is also a valuable nutrient. As a result, 40mg of zinc per day is considered to be the maximum safe amount if zinc is taken continually. As always, people should consult their doctor or pharmacist if they are already taking other medications because zinc could interfere with the effectiveness of those medications.

Most multivitamins for people over age 50, contain 11mg of Zinc.

multivitamins are deceptive as regards zinc. The 11mg of zinc oxide is not effective in entering immunologically active cells, is poorly absorbed. My own opinion is that such an inactive zinc inclusion routinely in multivitamins is the greatest sustainer of zinc deficiency in the US. Zinc chelates such a the gluconate, citrate, acetate, picolinate, bisglycinate (the best for absorption)are all effective at enhancing intracellular zinc levels with routine use. Zinc oxide and sulfate are not.

Multivitamins should have one of the above chelates included instead of zinc oxide.
