Hi Pam,
The National Institues of Health has a great website describing various COVID treatments under investigation or in use. This is the guidance they offer on zinc and COVID

Zinc: https://www.covid19treatmentguidelines.nih.gov/therapies/supplements/zinc/

Several clinical trials are currently investigating the use of zinc supplementation alone or in combination with hydroxychloroquine for the prevention and treatment of COVID-19. Until these studies are complete, the current recommendations are:

- There is not enough evidence for the COVID-19 Treatment Guidelines Panel (the Panel) to recommend either for or against the use of zinc for the treatment of COVID-19.
- The Panel recommends against using zinc supplementation above the recommended dietary allowance for the prevention of COVID-19, except in a clinical trial.

Pam, be sure to discuss further with your doctor. Long-term zinc supplementation can cause copper deficiency, which can cause other problems.
