How often do you take them? I have some that advise to stop using after seven days, which leaves me wondering whether I should take them as a precaution or take them if I feel any early indicators of a virus. Also, I notice that they dry out my tongue.

Do you mind sharing how many mg (milligrams) of zinc are in the one you have which advises to limit use to 7 days? I noticed that the Mayo clinic site says the maximum dose per day for an adult is 40 mg. I'm curious whether this 40 mg is safe for indefinite use, or such a 40 mg limit would also be for a maximum of 7 days.
