Yes, they were deficient in it. You better order some before you go extinct. They didn’t order any and look what happened to them.
I wondered about herpes meds possibly helping with the virus, as they are antivirals.
There are some other ‘fairly powerful’ antivirals out there... olive leaf, oil of oregano, as well as others. Supposedly oil of oregano and olive leaf will suppress the herpes virus, and other viruses that are tough to treat. Lysine too of course, they al, work similar. Though not sure if they’d work strongly enough to fight covid in folks that are sick or elderly if the virus really takes hold?
