Maca (Lepidium meyenii) is an adaptogenic herb that has been used traditionally in Peru for centuries. Some research suggests that maca may help support healthy testosterone levels in men.
Testosterone is an important hormone that is responsible for male characteristics like muscle mass, facial hair growth, libido, and sperm production. As men age, testosterone levels naturally decline, which can lead to unpleasant symptoms like low energy, decreased muscle mass, erectile dysfunction, and reduced libido.
Several studies have looked at whether taking maca supplements can increase testosterone levels in men. Here is a summary of some of the key research findings:
- A 2009 study published in the journal Andrologia found that taking 1,500-3,000 mg of maca per day for 4 months increased testosterone levels in healthy men aged 21-56 years old. The men also reported increased sexual desire after taking maca.
- A 2016 review published in the Chinese Journal of Integrative Medicine looked at 5 previous studies on maca and testosterone levels in men and postmenopausal women. The researchers concluded that maca significantly increased testosterone levels compared to a placebo. The effect was greater in men than women.
- Another 2016 study published in the Journal of Ethnopharmacology gave different doses of maca extract to adult male rats for 21 days. Rats given higher doses of maca showed significantly increased testosterone levels compared to a control group.
- A small 12-week study in 8 male cyclists found that consuming maca extract significantly increased free testosterone levels compared to a placebo. However, total testosterone levels remained unchanged.
- Some other small studies have not found a significant change in testosterone levels with maca supplementation. However, most studies used relatively short supplementation periods of 2-3 months.
The exact mechanisms by which maca may increase testosterone levels are not fully understood. Some possible ways maca may work include:
- Increasing luteinizing hormone (LH) - LH stimulates the Leydig cells in the testes to produce testosterone. Maca may increase LH levels.
- Improving leydig cell function - The leydig cells in the testes are responsible for making testosterone. Maca may enhance leydig cell structure and function.
- Boosting antioxidant levels - Maca contains high levels of antioxidants. These may reduce oxidative stress and promote healthy testosterone synthesis.
- Improving prostate health - Maca may help maintain a healthy prostate. The prostate plays an integral role in testosterone production.
- Enhancing fertility - Increased testosterone levels are linked to improved fertility in men. Maca has traditionally been used to enhance virility and fertility.
In summary, several studies suggest that maca may potentially help increase low testosterone levels in men, especially when used in sufficient doses for 2-4 months. The effects seem most pronounced in men with low baseline testosterone levels. However, more large-scale and long-term randomized controlled trials are still needed to better understand maca's effects on testosterone.
It's important to keep in mind that maca has not been proven to increase testosterone levels to super-physiological levels. It is not a replacement for bioidentical testosterone therapy. However, as an adaptogenic herb, maca may help bring low testosterone back to normal physiological range in some men.
If you're a man looking to naturally optimize your testosterone levels, maca may be worth considering in conjunction with lifestyle changes like exercise, nutrition, sleep, and stress management.
