The Longevity Fat You've Never Heard Of
How an odd-chain saturated fatty acid outperforms leading anti-aging drugs
Have you heard about C:15?
It’s one of the most powerful longevity compounds ever discovered.
The most interesting part?
How it was discovered.
And it has everything to do with dolphins…
In 2020, Navy scientists studied aging dolphins (link to study).
One group of dolphins had significantly fewer age-related diseases than the others.
When researchers analyzed their blood…
One molecule stood out: C15.
It’s a fatty acid they got from their fish-heavy diet.
The healthier dolphins had higher levels.
The sicker dolphins had lower levels.
So the researchers adjusted the diets of the lower-performing dolphins.
The result?
Insulin, glucose, and cholesterol levels improved.
Signs of chronic inflammation dropped.
Then they studied humans—and saw the same patterns.
People with higher circulating C15:0 had:
Lower rates of type 2 diabetes, cardiovascular disease, and fatty liver disease.
They also lived longer.
This was the first essential fatty acid discovered in over 90 years.
If you want to get it…
It’s in whole-fat dairy, grass-fed butter, and certain fish.
But levels vary significantly, and most people aren't eating enough of these foods consistently.
So I typically recommend Fatty15.
Fatty15 is on a mission to optimize your C15 levels to help support your long-term health and wellness - especially as you age.
