Clinical Applications
Maca (Lepidium meyenii Walp.) has been investigated for several clinical applications, though the evidence remains limited and mixed across different conditions.
Sexual Health and Dysfunction
The primary clinical focus for maca has been sexual dysfunction. A completed Phase 3 clinical trial (NCT00568126) investigated maca root specifically for antidepressant-induced sexual dysfunction in women, though detailed results are not provided in the available evidence. An ongoing trial (NCT05891327) is examining maca extract for male sexual dysfunction, but its status and results are unknown.
A narrative review from 2026 examined the use of specific maca phenotypes for men's hormone health, suggesting potential benefits for testosterone-related conditions. Supporting this, preclinical research in rabbits showed that black maca nano-emulsion influenced circulating testosterone levels and testicular vascular dynamics, though these animal studies cannot be directly extrapolated to human clinical outcomes.
Exercise Recovery and Muscle Health
A 2026 systematic review and meta-analysis of preclinical studies examined maca's effects on muscle damage biomarkers and post-exercise protein degradation. While this suggests potential applications for exercise recovery and muscle health, the review was limited to animal studies, and human clinical evidence for these applications is lacking.
Cancer Research
Laboratory research has investigated maca extracts' effects on prostate cancer cell models, examining impacts on cellular signaling, apoptosis, and lipid metabolism. However, these are early-stage laboratory studies and do not constitute clinical evidence for cancer treatment applications.
Current Evidence Limitations
The clinical evidence for maca remains thin across all investigated applications. While several trials are listed in clinical databases, many have unknown status or lack published results. The available research is predominantly preclinical, limiting conclusions about clinical efficacy and safety in humans.
