Regarding the zinc, staying within the RDA is probably safe. People who eat a lot of oysters and sea food would already be getting quite a bit of zinc. Safe but unless there's a deficiency, probaby useless. If it works, it's by sucking on zinc lozenges, not taking it orally. I don't remember the theoretical mechanism behind it.
