Thousands of years of traditional use, backed by modern randomized controlled trials.
Used in Peru for thousands of years, Maca root has multiple randomized controlled trials behind its use for male libido. Here's what the research says.
A randomized double-blind trial found men taking Maca for 12 weeks reported a significant improvement in sexual desire versus placebo — notably, without any change in testosterone or estrogen levels, suggesting Maca works through a different, non-hormonal mechanism.
This is Maca's best-supported use case: multiple studies link it to improved sexual desire independent of hormonal changes, which makes it a good fit for a best libido supplement aimed at general support rather than treating a specific hormonal deficiency.
Maca is also calorie-dense and nutrient-rich, which may partly explain its traditional use for energy and endurance, alongside unique compounds (macamides and macaenes) researched for mood support.
