It's in every glass of tonic water. Between 10 and 20 mg per glass. 10% of the HCQ dose provides 50% of the treatment effect. Low dose for medical quinine tablets is 200mg. High dose is 500mg. Basically, drink a glass of tonic water and have a zinc pill, or a standard multivitamin with zinc, together, every day, and covid will no longer kill you. You will always have zinc inside your cells. You have to maintain the dose every day, because the body creates new cells every day. If you ever do get infected with the virus, it will have a very hard time making new viruses inside your cells. Your immune system can do the rest. If you do somehow get infected drink a whole bottle of tonic water each day and take thirty mg of zinc, (normal adult daily requirement for zinc is 12mg.) If you can't get tonic water, drink green tea instead, and still add the zinc. The net effect is much the same. Zinc is also in your every day foods. A single chicken egg has 3 to 4 mg of zinc. My daily multivitamin has only 15mg of zinc in it, because it is unusual to be zinc deficient. Women need only 8mg per day, and men need 12mg. Normally you easily surpass that in your food, and the multivitamin added zinc is overkill.
