Hi doctors, my 14 year old son is going through a really difficult puberty. He is emotional and angry and his skin is breaking out terribly. Can you suggest a good vitamin that could help his skin, as well as relax him?

I wouldn't. I know of no vitamin or other OTC product that would make any change in what you are describing. This sounds like you need to find an unrelated therapist/counsellor or psychiatrist to deal with his emotional state. A trip to his primary care doc for acne therapy would also be wise.
