Whats the difference in zinc powder and zinc that you get at the drug store?

Zinc powder is finely divided metallic zinc, so fine it is like dust, but as such, is still pure, metallic zinc.


Drug stores do not sell zinc. Drug stores might sell many products containing zinc compounds, but there's nothing about metallic zinc (powder or not) which would be appropriate for use on or in the body. There are ointments with zinc oxide in them, dietary supplements with zinc compounds in them, etc. No zinc metal at the drug store.
