Safe Ionophore for PFS: Quercetin, EGCG, Resveratrol?

I’m looking for a safe ionophore to get more zinc into my cells, in an effort to boost my immune system.

Does any of you knows which one of the natural ionophore; Quercetin, EGCG (EpiGalloCathetineGallate), Resveratrol, is the least damaging for a guy with pfs.

I can also use Ivermectin (an anti-parasite) and Famotidine (Pepcid AC, for stomach burn) for the same ionophore purpose but I’m not sure of their effectiveness. I heard some anti-malaria drugs can have similar ionophore caracteristic.

Does anyone have any information on these, related to pfs ?

Thank you.
