May increase libido

Some data suggests that taking concentrated maca supplements may help people who have poor libido or sexual desire. A 2015 research of 45 women with antidepressant-induced sexual dysfunction discovered that consuming 3,000 mg of maca root per day for 12 weeks dramatically improved sexual function and libido when compared to a placebo. A 2010 assessment of four high-quality studies including 131 participants discovered evidence that ingesting maca boosted sexual desire after at least 6 weeks.

The researchers did warn, however, that the studies included in the review were tiny, and the evidence was insufficient to draw clear conclusions. Despite this encouraging research, it is yet unknown whether maca provides any meaningful value for treating low libido or sexual dysfunction.
