1. Increasing libido
The most well-known benefit of maca root is its potential to increase libido. There is some scientific evidence to support this claim.
A 2010 review of studies on maca and sexual functioning found some evidence to suggest maca could improve libido, but the authors cautioned that more research is required.
2. Reducing erectile dysfunction
Maca root could also have benefits for people with erectile dysfunction (ED). A small study in 2009 looked at the effect of consuming 2.4g of maca root per day for 12 weeks on participants’ perception of their general and sexual well-being.
The study participants were males with mild ED. Those taking maca root experienced a more significant increase in sexual well-being than those taking a placebo.
3. Boosting energy and endurance
Some athletes and bodybuilders use maca root as a supplement to increase energy and performance. Some evidence exists to support this.
A pilot study in 2009 found that using maca extract for 14 days improved performance for male cyclists in a 40-kilometer time trial. However, the results were not significantly different from the improvement seen in those taking a placebo.
However, the same study found that maca extract improved libido in the participants who used it. However, the sample size of this study was very small, so more research is needed to confirm the results.
4. Increasing fertility
Another widespread use of maca root is to increase fertility, particularly in men.
5. Improving mood
Also, a 2015 study found that maca could reduce symptoms of depression in Chinese postmenopausal women.
6. Reducing blood pressure
7. Reducing sun damage
An older study in an animal model found that maca might help protect the skin from UV rays. Another animal study in 2011 found that extracts from maca leaves might help prevent the formation of sunburn cells.
8. Fighting free radicals
Maca root also promotes natural antioxidants in the body, such as glutathione and superoxide dismutase.
9. Reducing menopause symptoms
Some proponents of maca root believe it may help balance levels of the hormone estrogen. During perimenopause, the stage before a woman reaches menopause, estrogen levels fluctuate and cause a variety of symptoms.
One study found that postmenopausal women who took two daily tablets containing maca experienced reduced symptoms, such as hot flashes and night sweats.
10. Improving learning and memory
There is some evidence to suggest that maca can improve learning and memory. For example, a 2011 study found that maca could improve memory in mice.
A 2014 review of the literature suggested that maca may have benefits for learning and memory performance. Researchers suggested that it could be helpful in treating conditions that affect these processes, such as Alzheimer’s disease.
