ELI5 why does taking a multi-vitamin on an empty stomach cause nausea, but something like Tylenol doesn’t?

I was not aware that multivitamins had a tendency to cause nausea (they don't for me, personally). That said, I've been told that taking them on an empty stomach means it won't be absorbed nearly as well compared to with a meal. Perhaps the absorption and nausea are related?
