As revenues from the anti-aging market — riddled with hope and thousands of supplements — surged past $500 million last year, Emory University researchers identified a compound that actively delays aging in cells and organisms.
A newly published study in Nature Partner Journals’ Aging demonstrates that psilocin, a byproduct of consuming psilocybin, the active ingredient in psychedelic mushrooms, extended the cellular lifespan of human skin and lung cells by more than 50%.

While traditionally researched for its mental health benefits, this study suggests that psilocybin impacts multiple hallmarks of aging by reducing oxidative stress, improving DNA repair responses, and preserving telomere length. Telomeres are the structured ends of a chromosome, protecting it from damage that could lead to the formation of age-related diseases, such as cancer, neurodegeneration, or cardiovascular disease. These foundational processes influence human aging and the onset of these chronic diseases.
The study concludes that psilocybin may have the potential to revolutionize anti-aging therapies and could be an impactful intervention in an aging population.
“Most cells in the body express serotonin receptors, and this study opens a new frontier for how psilocybin could influence systemic aging processes, particularly when administered later in life,” says Louise Hecker, PhD, senior author on the study, and former associate professor at Emory University, where the research was initiated and funded.
While much of what researchers know about psilocybin relates to the brain, few studies have examined its systemic impacts. Many people associate psilocybin with the hallucinogenic impacts, but the majority of the cells in the body express serotonin receptors.
“Our study opens new questions about what long-term treatments can do. Additionally, even when the intervention is initiated late in life in mice, it still leads to improved survival, which is clinically relevant in healthy aging,” adds Hecker, currently an associate professor at Baylor College of Medicine.
Not just a longer life, but a healthier life
This news comes on the heels of KFF’s recent report that U.S. life expectancy is still below that of other countries similar in income and size, with an average lifespan of 78.4 years, compared to 82.5 years elsewhere. Not only was it the lowest, but as the lifespan in similar countries increased by 7.9 years from 1980-2022, the U.S. life expectancy has only increased by 4.7 years.

“This study provides strong preclinical evidence that psilocybin may contribute to healthier aging — not just a longer lifespan, but a better quality of life in later years,” says Ali John Zarrabi, MD, director of psychedelic research at Emory University’s Department of Psychiatry. “As a palliative care physician-scientist, one of my biggest concerns is prolonging life at the cost of dignity and function. But these mice weren’t just surviving longer — they experienced better aging,” adds Zarrabi, co-investigator of the study.
Zarrabi emphasizes the importance of further research in older adults, as well as the well-documented overlap between physical and mental health.
