Weekend reading: Immunity, Covid-19, and Generally Good Health
A reader, Philly Nassau, sent me the ingredient list of several “immune-boosting” supplements, in quotes because I am a supplement skeptic in general, and of immune supplements in particular (I favor eating healthfully and staying active).
