Neli: Maca powder does it have sides effects?
Walter Last: I do not personally know of any side effects of maca. On the Internet it generally says that there are no side effects, but a few say that when too much is taken then occasionally there may be difficulty sleeping, or some women may develop breast tenderness. In these case the dose should be reduced until there is no problem.
