The Quick Verdict
Maca's research on sexual desire specifically is more encouraging than for stamina broadly — a useful, honest distinction most marketing glosses over.
Long before it appeared on a supplement label, Maca root was a staple crop in the high-altitude regions of the Peruvian Andes, used traditionally for centuries to support energy and endurance in a demanding, oxygen-thin environment.
What Maca Actually Is
Lepidium meyenii, commonly known as Maca, is a cruciferous root vegetable — related botanically to broccoli and radishes, not an exotic rainforest extract despite how it's sometimes marketed. It grows at altitudes above 4,000 meters, where few other crops survive, which is part of why it became such a dietary staple for Andean communities historically.
What the Research Shows
A study published in Andrologia examined the effect of Maca on sexual desire specifically, finding a measurable improvement in self-reported libido among the men studied, independent of any change in mood or testosterone levels — which is a notable finding, since it suggests Maca's effect isn't simply a side effect of feeling better generally.

An Honest Distinction Worth Making
Marketing copy for Maca often blurs "stamina," "energy" and "libido" together as if they're the same finding. The research above is specifically about sexual desire — not a broad energy or athletic-stamina claim. That's a meaningful distinction, and one worth being upfront about rather than letting the terms blur together.
Why It's Part of the Formula
Maca Root Extract is one of JellyBoost®'s seven disclosed active ingredients specifically for this libido-support research, paired with Tongkat Ali for testosterone status and L-Arginine and Beet Root for circulation — three distinct, complementary mechanisms rather than three ingredients chasing the same effect.
