In a study recently published in the Journal of Exercise and Nutrition, 22 males and 25 females were randomly assigned to receive either placebo or 2.1 g of a patented Peruvian maca (Lepidamax from Nutrition 21) for 28 days. Researchers utilized the Shapiro Test to test the effects of maca on grip strength, mood, and sexual functioning, and a Nonparametric Wilcoxon Rank Test to examine the differences between groups for men and women separately.

Results showed that men taking maca had a significant improvement in handgrip strength, sexual function, and a reduction in fatigue, compared to placebo. Women taking maca saw a significant improvement in fatigue, mood, sexual function, and handgrip compared to baseline, but these improvements were not significant when compared to placebo.

“We’re excited to see that these clinical study results support Lepidamax’s ability to effectively enhance various end-points related to men’s health, enabling end-users to break through potential performance barriers,” said Joe Weiss, president of Nutrition 21, in a press release. “This study confirms our previous understandings around this ingredient and has exceeded our expectations regarding the possible applications for Lepidamax.”
