Hi friend!

What if one of the most exciting longevity nutrients on the planet is not coming from a lab, but from mycelium?

Geoff Palmer (vegan for 40+ years, former AAU swimmer, natural bodybuilding champion, founder of Clean Machine) wants more people talking about mycelium and a mycelium-derived compound called spermidine, which he believes might be “the most powerful longevity nutrient on the planet.”

So what is spermidine, and why are people paying attention?

Spermidine is a naturally occurring compound found in all living cells. Geoff says it supports key processes linked to healthy aging, including autophagy, your body’s cellular clean-up process. When autophagy is active, cells can repair and renew more effectively.

If you want the full breakdown, we covered it here:

Now here’s where it gets really interesting.

Geoff thinks mycelium could be a major next step for nutrition, not only for longevity, but for the future of sustainable protein too.

A video on our YouTube channel exploring these ideas has already reached nearly 500,000 views, and it has sparked a lot of “wait, why isn’t everyone talking about this?” reactions:

We have a brand-new interview between PBN Founder Klaus Mitchell and Geoff Palmer called:

This Could Be the Future of Protein w/ Geoff Palmer

In it, Geoff talks about how the protein category evolved (whey, plant, collagen) and why he believes mycelium protein could be the next big shift. He also explains why spermidine is such a hot topic in longevity right now.

If you are curious about the product he created off the back of this research, it’s called MycelPro-1, and it’s positioned as a single-ingredient mycelium protein that could genuinely shake up the protein industry:

If nothing else, this is a fun one to explore. Nature keeps surprising us.

See you on YouTube on the 18th,
