Maca: libido, energy, menopause and level of evidence
Short answer: Maca (Lepidium meyenii) is an Andean plant traditionally consumed as a food and tonic. A few human trials suggest possible benefits for sexual desire or certain menopausal symptoms, but systematic reviews conclude that the evidence remains limited.
What is Maca?
Maca grows in the Andes and the part consumed is the hypocotyl, often dried and then processed into powder or extract. Its modern reputation associates it with energy, libido, fertility and “hormonal balance,” but these claims do not all have the same level of evidence.
Maca and libido
A systematic review of randomized trials found some positive results for sexual desire or function, but the number of studies and participants was small. It is therefore more accurate to speak of a possible clinical signal than a guaranteed effect.
One study in healthy men observed a change in sexual desire without a parallel change in testosterone. This is a reminder that a perceived effect on libido does not necessarily mean that Maca “increases hormones.”
Maca and menopause
A few trials have studied Maca in peri- or postmenopausal women. A systematic review judged the results encouraging but insufficient for firm conclusions. A small study also observed improvements in some symptoms without significant changes in measured hormone concentrations.
Maca and energy
Maca is traditionally used as an energy food in the Andes, but specific clinical evidence on fatigue or performance is less robust than marketing messages suggest. It should not be presented as a stimulant or as a treatment for fatigue.
Do Maca colors change everything?
Yellow, red and black varieties exist and their composition may differ. Human evidence does not currently allow us to state that one color is systematically “better” for a specific objective.
How to choose?
- origin and species clearly stated;
- powder or extract identified;
- contaminant analyses available;
- no exaggerated hormonal claims;
- transparent dosage and ingredients.
Maca, Ashwagandha or Tongkat Ali?
For stress, Ashwagandha has more human trials. For male testosterone, Tongkat Ali has been evaluated in a dedicated meta-analysis. To compare these approaches, see our adaptogens guide.
Precautions
Maca is also consumed as food, but safety data for concentrated extracts are more limited. During pregnancy or breastfeeding, with a hormone-sensitive condition or medical treatment, seek professional advice before using a concentrated supplement.
FAQ
Does Maca increase testosterone?
This has not been demonstrated in general. Some studies on sexual desire found no increase in testosterone.
Does Maca treat menopause?
No. A few trials are encouraging for certain symptoms, but the level of evidence remains limited.
Which color of Maca should you choose?
Differences in composition are interesting, but human evidence is insufficient to assign a precise benefit to each color.
Key takeaway
Maca is an interesting Andean food plant with some human data on libido and menopause. It deserves a nuanced presentation without turning it into a universal “hormone regulator.”
