I have heard that Vitamin E can help enhance sex drive, is this true?

If so, how much would you recommend and could it be a bad idea to add another supplement to only treat a symptom without actually fixing the problem itself?

If we or doctors knew how to fix the problem, none of us would be here.

Supplements are just that – supplements. Up to you to research them, ask doctors about them etc. Nobody can give you definite answers, we’re just laymen.
