I’ve recently seen (and given) this recommendation on LW for the common cold. https://www.lesswrong.com/posts/un2fgBad4uqqwm9sH/is-this-info-on-zinc-lozenges-accurate is afaik the best write-up on the subject, which is sad.
In the distant past, I also saw and echoed this recommendation speculatively for covid. (I also followed it, I would suck on a lozenge when I went shopping for a while.) But I don’t think I’ve heard anything about it recently, on LW or elsewhere.
