In summary, the primary reason HCQ is effective is that it provides a pathway for blood Zinc to enter into the Wuhan Virus. The Zinc once within the virus prevents the virus from replicating.
If a person has adequate blood Zinc levels there is evidence the addition of a Zinc supplement is not needed. But, it cannot hurt if it is administered. For those with a very low blood Zinc level, the supplement is absolutely necessary. Otherwise, the HCQ is not very effective.
My doctor told me a few months ago to start taking zinc.
I take it once a day with food.
