Urolithin A for Anti-Aging

Preliminary evidence 17 studies

Research suggests that urolithin A (UA) holds promise as an anti-aging compound across a range of biological systems, with studies in model organisms such as C. elegans and mice consistently reporting benefits including extended lifespan, reduced oxidative stress, improved mitochondrial function through mitophagy, reduced markers of cellular senescence, and protection against age-related muscle and cognitive decline. The body of evidence reviewed here consists primarily of preclinical studies — including animal models, cell culture experiments, and invertebrate models — along with several narrative reviews, with no randomized controlled trials in humans included in this set; the overall direction of the literature is supportive, though a small number of studies are characterized as mixed or neutral, particularly those examining applications in reproductive biology and lung disease where findings were more nuanced or context-dependent. Studies indicate that UA's biological activity depends substantially on an individual's gut microbiome composition, as the ability to convert dietary ellagitannins from foods like pomegranates and berries into UA varies between people, and research has found that conditions like inflammatory bowel disease may reduce this conversion capacity. The absence of large-scale human clinical trial data is a notable limitation, and while the preclinical evidence is consistently encouraging, researchers across multiple studies acknowledge that more rigorous human studies are needed before conclusions about effectiveness and safety in people can be drawn.
