Psilocybin extends lifespan in Mice (Patreon)

TL;DR:

Psilocybin — the compound in magic mushrooms — extended cell lifespan by 50% and boosted survival in aged mice by 30% in an Emory University study. The effects included shinier fur, hair regrowth, and healthier aging markers. Researchers believe it works by reducing oxidative stress, improving DNA repair, and preserving telomeres. Human trials are next to see if it can slow aging in people.

As for chaga or lion’s mane powder in my coffee - sadly...

• Chaga (Inonotus obliquus) i take for antioxidants, immune modulation, and potential anti-inflammatory effects, but no psilocybin — so it won’t replicate “magic mushroom” effects.

• Lion’s Mane (Hericium erinaceus) helps me w nerve growth factor (NGF), cognitive health, and potentially mood, but again no psilocybin — it’s non-psychedelic.

Here is the paper

Magic mushrooms may hold the secret to living longer.

In a new study, psilocybin extended cell lifespan by over 50% and increased survival in aged mice by 30%.

Psilocybin, the psychoactive compound in psychedelic mushrooms, may do more than alter perception — it could slow the march of time itself.

A new Emory University study, published in Nature Partner Journals: Aging, found that psilocin — the active form of psilocybin once metabolized — extended the lifespan of human skin and lung cells by over 50%.

In long-term experiments on aged mice, a regimen beginning with a low psilocybin dose followed by monthly higher doses for 10 months increased survival by 30% compared to untreated mice. These mice not only lived longer but showed signs of healthier aging, including shinier fur, fewer white hairs, and regrowth.

Researchers suggest psilocybin influences key cellular aging mechanisms such as reducing oxidative stress, enhancing DNA repair, and preserving telomeres — the protective chromosome caps linked to age-related diseases.

While psilocybin is most often studied for its mental health benefits, this research highlights its potential systemic effects throughout the body, given that most cells express serotonin receptors. Even when introduced late in life, the intervention improved survival and physical health in mice, raising hopes for similar effects in humans.

With U.S. life expectancy lagging behind comparable nations, the findings offer a glimpse into a future where psilocybin could support not just a longer life, but a healthier one.

As senior author Louise Hecker, PhD, noted, the results “open a new frontier” in anti-aging therapies, while co-investigator Ali Zarrabi, MD, emphasized that longevity gains should enhance dignity and function — not merely extend years. Clinical trials in humans will be essential to see if the promise holds.
