You might have already seen it pop up: researchers have discovered that psilocybin – the compound found in magic mushrooms – appears to keep cells younger for longer. Sounds like something out of a sci-fi movie, but it’s right there in npj Aging, a scientific journal by Nature. Let’s dive in.
Some context first
There are currently over 150 clinical studies on psilocybin running worldwide. For depression, anxiety, addiction, Alzheimer’s, chronic pain – you name it. What stands out: a single dose can sometimes have effects that last for years. Up to five years, according to some studies.
But how is that possible? Science hasn’t fully figured that out yet. Most studies focus on what happens in your brain. This new study looked at something different: what does psilocybin do to your cells?
The psilocybin-telomere hypothesis
Let’s take a step back. You may have heard of telomeres – the “protective caps” at the ends of your chromosomes. Every time a cell divides, those caps get a little shorter. Until they’re gone. Then the cell stops dividing and goes into sleep mode. Scientists call this senescence. Basically: your cells grow old.
There’s been a theory floating around for a while – the “psilocybin-telomere hypothesis” – which suggests that psilocybin may influence this process. Depression and chronic stress have been linked to shorter telomeres. Psilocybin helps against depression. So maybe… it also helps prevent telomere shortening?
Nobody had ever tested this directly. Until now.
The study – part 1: cells
Scientists at Emory University and Baylor College of Medicine treated human lung and skin cells with psilocin (the substance your body converts psilocybin into). They monitored how long it took before those cells were “done.”
What they found:
Treated lung cells lived 57% longer. Skin cells 51%.
But there was more. The treated cells also showed:
- Fewer signs of aging (lower β-galactosidase activity – a marker for old cells)
- Less oxidative stress (a major driver of aging)
- Preserved telomere length – where untreated cells developed shorter telomeres, treated cells kept theirs intact
- Increased levels of SIRT1 – a protein that plays a crucial role in cellular aging, metabolism and stress response
The study – part 2: in vivo
Cells in a lab are one thing. But does it work in a living organism too? To test this, the researchers used older mice aged 19 months – comparable to humans aged 60-65.
These mice received a monthly dose of psilocybin for ten months. The results?
After 10 months, 80% of the treated mice were still alive. In the control group? Just 50%.
And they didn’t just live longer – they looked better too. The researchers noted improvements in fur quality: more hair growth, fewer grey hairs.
How does this work?
Psilocybin works through the 5-HT2A receptor, a serotonin receptor. It’s not just in your brain – it’s found in all kinds of cell types throughout your body: fibroblasts, neurons, heart muscle cells, immune cells.
Previous studies already showed that stimulating this receptor can lead to increased SIRT1 production. SIRT1 is a key player in aging – elevated levels have previously been linked to longer lifespans in other organisms.
This study suggests that this mechanism may be responsible for both the cell-rejuvenating effects and the increased lifespan.
🍄 Quick side note: The Drops contain 4-HO-MET and 4-PRO-MET, synthetic analogues that work through the same 5-HT2A receptor as psilocybin.
What does this mean?
Is this definitive proof that psilocybin is the fountain of youth? No. It’s one study. On cells and mice – not humans. Much more research is needed.
But it is the first experimental evidence that psilocybin impacts fundamental aging processes. Both at cell level and in a living organism. And that’s fascinating.
The researchers themselves conclude: psilocybin could be a “potent geroprotective agent” – in plain English: a powerful compound that protects against aging.
An interesting footnote: the FDA has designated psilocybin as a “breakthrough therapy” – a status only given to treatments that show substantial improvement over existing options.
