Since I have no symptoms of covid-19, I can’t get prescription for HCQ. So I am doing the next best thing, eating foods rich in zinc (shell fish, nuts, red meat etc) and drinking tonic water with Quinine LOL.
Zinc ionophores (zinc uptake transport molecules): HCQ , quercetin supplement (say 400 mg), ECGC, green tea, elderberries, blueberries.
If using a zinc supplement, take the zinc supplement either as a lozenge or as zinc picolinate or zinc gluconate. Good absorption.
You need a low stomach PH (that is, you need acid in your stomach) to dissolve/absorb zinc and older people are often a bit low in that department. A little apple cider vinegar can help.
Quercetin can work to drive zinc into cells.
