I have a friend who is on immune surpessants due to other problems.
Lives in a state where HClQ is banned. And in the county with the highest number of Covid cases in a four state area.. Is a volunteer Firefighter / EMS so is exposed to people dying of Covid.
He drinks a quart of tonic water and takes 100mg zinc Piccolinate daily. Hasn’t gotten sick yet.
Good for him; but if I were him I would also take the quercetin. The quinine in tonic water isn’t that concentrated, and sometimes the smallest change can have a huge effect.
