If you are worried about the OptiZinc, take it every other day.

But you will need more than others because 1) you do not eat shellfish or meat, and you are mostly vegetarian 2) you take lisinopril which depletes zinc.

The copper is in OptiZinc because some people take more than one tablet a day. Pyrolurics do this treatment. When high dose zinc is used every day, copper levels can fall, so they include it in the tablet. It is not terribly significant unless you use more than a tablet a day.
Here is a monograph on copper
