Chloroquine also seems to act as a zinc ionophore, that allows extracellular zinc to enter the cell and inhibit viral RNA-dependent RNA polymerase

Medcram has a detailed explanation of how Chloroquine works with Zinc to stop the virus. The Chloroquine is used as an ion transport to get Zinc into the cell to stop the replication of the virus.
Quinine derivatives are also Zinc ionophores, they increase the concentration of intracellular zinc. The viral replicase enzyme of n-COV-19 is gummed up by Zinc slowing replication.

I know, I know not enough testing for you but most think that the mechanism of quinine like meds work by transporting Zn into cells and interfering with RNA replication. A large percentage of people have good levels of Zn but not sure if enough to be used for this transport in to most of your cells. IMHO taking a little extra Zn may help and I doubt it would be detrimental to most people.
I would encourage you to investigate it from a MD viewpoint and tell us what you think.
