Maca, Native to Peru, was origionally used to enhance fertility and sex drive. It can be added to smoothies, porridge, or baked goods. Maca can also relieve the effects of menopause.
Supplementing with maca may improve exercise performance, particularly during endurance events. However, its effects on muscle mass and strength have yet to be studied.
Maca is considered safe for most people, although those with thyroid issues need to be careful.
