Do you happen to know the dosage of zinc that your acquaintance used to recover her senses of taste and of smell?
No, I don't recall. That's why I shared the information that a maximum safe dose is 150 mg/day.
While searching in case I posted the information about zinc earlier, I found a post of mine passing on a warning that lysine (known as an anti-viral) concentrates zinc so you don't want to be taking zinc and lysine at the same time.
