This zinc supplement delivers a full 25mg per tablet for immune support, a solid daily dose that stays comfortably under the 40mg safety ceiling. The reason it's a complex: your zinc is split evenly between **zinc picolinate** and **zinc bisglycinate**, two of the most readily absorbed forms, so more of the dose actually reaches your cells.

It also pairs in 1mg of copper in a well-absorbed bisglycinate form, at a sensible 25-to-1 ratio. This matters more than it sounds: taking 25mg of zinc daily over months can slowly deplete your copper, and the added copper keeps that balance from tipping.

At 25mg, this is steady daily coverage rather than a short-term therapeutic megadose, and the label's once-daily-with-food direction fits that purpose. It's a good match if you want consistent, well-absorbed zinc with the copper balance already built in.
