Maca is an adaptogenic plant native to the Andes, traditionally used to enhance fertility, energy, and libido. Its potential healthspan relevance is indirect, possibly through improved stress resilience and vitality, rather than direct modulation of core aging pathways. While it contains unique bioactive compounds like macamides, robust evidence linking it to significant lifespan extension is currently lacking.
Verdict
Potentially useful for vitality, but not a core longevity intervention.
