Research suggests that maca root has not yet demonstrated sufficient evidence to be considered a promising ingredient for mental energy, mood, or related outcomes in the current literature. A 2024 scoping review examining randomized controlled trials across 16 dietary ingredients found that 11 of them showed at least preliminary directional evidence of mental energy benefits, but maca root was not among those highlighted. Studies indicate that the overall body of evidence for maca in this context remains limited, and the review's authors note that significant variability in study design and outcome measurement makes it difficult to draw firm conclusions about any ingredient in this space. More rigorously standardized clinical trials would be needed before meaningful claims about maca root and energy or fatigue could be supported.
