Maca is a radish-like tuber native to the Peruvian Andes, and has been used for thousands of years by the local population. Maca has been traditionally used as a source for energy, stamina, and endurance. The anti-fatigue effect of maca has been extensively studied and results are promising.*

Energy

Maca has been traditionally used for medicinal purposes and as a source for energy, stamina and endurance. The anti-fatigue effect of macahas been extensively studied in animals and human studies are promising.

Researchers found that mice supplemented with polysaccharides from maca over 28 days had significantly prolonged exhaustive swimming times compared to control. While low, middle and high-dose groups experienced prolonged swimming time, the effect appeared to be dose-dependent, with mice consuming high-dose maca (2,000 mg/kg) experiencing the greatest improvements in prolonged swimming until exhaustion.

Endpoints from a randomized, double-blind, placebo controlled trial on 175 healthy adults living at low-altitude found that consumption of 3g maca (bothblack and red) increased energy compared with placebo starting at week 2 and remained elevated until the end of the trial (week 12). Over 80% of subjects reported increased mood and energy following maca consumption.

Fitness performance

In addition to energy, maca is traditionally used in Peru to support performance and endurance. Human clinical trials are emerging in this area and more studies need to be Page 2of 3conducted. A placebo-controlled pilot investigation studying the effects of maca supplementation on endurance performance in male cyclists found that 2 g maca daily for 14 days significantly improved 40 km cycling time performance compared to baseline.

Sexual function and libido

Maca root has been traditionally used for centuries in the Peruvian culture for enhancing fertility and its aphrodisiac properties in men. With sexual functionbeing an important component for men’s overall well-being, mainstream use of maca to support sexual function is increasing. As interest in this herb is growing, more scientific research is being done to support its benefits.

In a 12-week double-blind, placebo-controlled, prospective, randomized trial of 20 healthy men, supplementation with 1.75g of maca significantly improved all sperm quality parameters. After 12 weeks, total sperm count increased by 20%, sperm concentration increased by 14%, motile sperm count increased by 14%, progressively motile sperm count increased by 18%, semen volume increased by 9% and normal morphology of sperm increasedby 21% (3).

Another study of 9 healthy men found that after 16 weeks, maca supplementation significantly increased sperm concentration by 35%, total sperm count by 84% and motile sperm count by 109% (4).

With respect to sexual desire, a randomized, double-blind, placebo-controlled study of 175 participants found that approximately 50% of individuals given 3g of maca for 12 weeks reported an increase in sexual desire(1). Another randomized, placebo-controlled study of 8 male cyclists found that overall sexual desire significantly increased with supplementation of 2g maca daily for 14 days compared to baseline and placebo (2).
