Things that supposedly aid in Covid prevention.
Not vouching for any.
Melatonin
Famotidine
Zinc 50mg
Fexofinadine
B12
D3
I had the virus right after Thanksgiving. My wife (who also tested positive) and I doubled down on B3, zinc, vitamin C and Melatonin. I attribute the fact that we both recovered in three or four days to those vitamins.
