From the Peruvian highlands to peer-reviewed journals โ here's what clinical research actually shows about Maca's impact on male libido, energy, and stamina.

High in the Peruvian Andes, at altitudes over 12,000 feet where few crops can survive, farmers have cultivated a small cruciferous root called Maca (Lepidium meyenii) for more than 2,000 years. Traditionally used to support energy and stamina in harsh mountain conditions, Maca has since made the leap from Andean folk medicine to clinical research journals โ and into JellyFil's formula.
Maca is a root vegetable in the same family as broccoli and kale, though its use in supplements focuses on its dried, powdered root extract rather than as a leafy vegetable. It's typically categorized in three colors โ yellow, red, and black โ with slightly different traditional uses, though most modern research and supplement formulations use standardized extracts that don't distinguish heavily between colors.
Unlike many traditional herbs, Maca has actually been studied in randomized, placebo-controlled human trials โ which is relatively rare for botanical ingredients.
A randomized, double-blind clinical trial published in Andrologia found that men taking Maca extract for 12 weeks experienced a 42% improvement in sexual desire compared to the placebo group. This wasn't a subjective or self-reported change alone โ the study used standardized psychological scales to measure libido before and after supplementation.
A separate meta-analysis of four randomized controlled trials, published in BMC Complementary and Alternative Medicine, confirmed significant improvements in sexual dysfunction and libido scores among men taking Maca, reinforcing that the effect wasn't isolated to a single study.
Here's what makes Maca's research particularly interesting: unlike ingredients such as Tribulus Terrestris or Ashwagandha, which are studied for their effects on testosterone or cortisol, Maca's libido-supporting effects appear to occur without significantly altering hormone levels.
Maca's traditional use by Andean laborers and athletes for endurance is echoed in some modern sports nutrition research, where Maca supplementation has been studied for its potential to support energy levels and reduce feelings of fatigue during physical activity. While this body of research is smaller than the libido-focused studies, it aligns with Maca's centuries-old reputation as an energy-supporting food.
You may see supplements distinguish between "raw" and "gelatinized" Maca. Gelatinization is a heat-based process that removes starch and is believed to make the root easier to digest โ it's the more common form used in supplement manufacturing, including standardized extracts used in clinical research.
Maca is generally recognized as safe and well-tolerated in the doses used in clinical studies. However, you should consult your doctor before using Maca-containing supplements if you:
