Alright guys, I need a hand. My boss, a former body-builder, claims that grapefruit juice is beneficial to drink when taking antibiotics. This is because of some chemical in the juice that allows for a greater yield to be administered to the body from the pill. Now, from what I've found on google so far, this is basically true. And doctors warn against drinking grapefruit juice for most medications for this very reason, overdoses would be common and what not. The question is though, with respect to a bacterial infection that you're on antibiotics, is it wise to drink grapefruit juice?
I posted this in Myth Busters, because the claim just has one of those "bullshit" qualities about it, so I want a skeptical response if possible. If I'm in the wrong forum, by all means, move the topic.
