It is also used to enhance fertility and treat erectile dysfunction.
However, it’s important to note that there is not enough human-based research to fully support its uses.

That means some supplement products may not contain what the label says.
No supplement is intended to treat, cure, or prevent disease.
Research on the potential health benefits is limited.
More research is needed.
Here is a look at findings from available human research.
Erectile Dysfunction
Maca root supplementation has been reported to improve sexual function.
However, evidence is limited and reports are mostly subjective.
Those in the treatment group took 2.4 grams (g) of maca for 12 weeks.
After 12 weeks, both groups had reduced ED.
However, the group given the maca showed a higher increase in erectile function than the placebo group.
Still, the effects were minor overall.
In another report, researchers analyzed four previous clinical trials.
Some of the studies found that maca had positive effects on improving sexual function in men and women.
Overall, evidence of maca root’s ability to boost sexual function is sparse.
There is also not enough data to determine the appropriate dosage needed.
Low Libido
Maca root supplementation has been reported to improve lowlibido(low sexual desire).
However, evidence is weak and reports are mostly subjective.
Maca root has been studied for its use in alleviating antidepressant-induced sexual dysfunction in women.
Certain antidepressants cause side effects like low libido, vaginal dryness, and difficulty reaching orgasm.
Researchers encouraged more extensive studies and fewer self-reported results.
It is important to remember that these findings were subjective and based on individual experiences.
Talk to your healthcare provider about potential ways to mitigate these antidepressant-related side effects.
Fertility
Several studies have measured the effects of maca on male fertility.
Overall, it is advised to consult a healthcare provider if you are concerned about semen quality and fertility.
Energy Level
Limited evidence suggests that maca may help improve energy levels.
In a 2022 study, 60 participants were given maca extract or a placebo for four weeks.
Both groups showed reduced measures of fatigue.
However, people younger than 45 years showed significantly lower fatigue measures in the maca group.
The study authors concluded maca extract may have anti-fatigue effects in young adult women.
Symptoms of Menopause
Menopause is a natural process when menstrual periods stop.
A review of four studies suggests maca may help menopausal symptoms.
Side Effects of Maca Root
Consuming a supplement like maca root may have potential side effects.
These side effects may be mild or severe.
Little is known about the safety and risks of short-term or long-term use of maca.
Side effects of maca root are generally uncommon and mild and may include gastrointestinal symptoms or headaches.
Maca’s effect on hormone levels is poorly understood.
Due to this lack of information, it should not be used in these groups.
Talk to your healthcare provider before taking maca root if you are pregnant or are on any hormone treatments.
There is insufficient evidence to determine a standard or appropriate dose of maca root.
Studies investigating maca root have used varying amounts.
However, research participants are generally under medical supervision.
More research is needed on an appropriate dosage for specific health needs and populations.
This may differ depending on the preparation used (e.g., capsules, liquid, powder).
Talk to your healthcare provider about the most appropriate dosage for you.
It can be found in health food stores.
It is also sometimes added to foods.
Its nutty, earthy flavor pairs well with cinnamon.
It is often consumed as a juice or prepared as a vegetable dish.
Summary
Maca root is a vegetable native to the Andes region of Peru.
Reports have suggested that maca root improves sexual function, libido, and sperm quality.
However, the evidence is limited and largely subjective.
More large-scale clinical trials are needed to confirm these health claims.
Little is known about the short- and long-term side effects of taking maca root.
