Talk of the Town: How C15:0 May be Essential to Slow Down Aging

Dr. Eric Venn-Watson’s Highlights
-
- As featured in New York Times, what started as a surprising discovery to protect dolphins’ health has become a growing movement to restore our body’s C15:0 levels, support our long-term health, and perhaps even slow aging.
- Declining hemoglobin is emerging as an important sign of accelerated aging. Extensive studies have shown that C15:0 can help raise hemoglobin and reverse multiple hallmarks of aging at the cellular level.*
- Fatty15 is an award-winning, science-backed C15:0 supplement that can help replenish age-related C15:0 declines and restore your long-term health.*
What started as a surprising discovery to protect dolphins’ health has become a growing movement to restore our body’s C15:0 levels, support our long-term health, and perhaps even slow aging.
The groundbreaking discoveries around C15:0’s healthy aging benefits have been featured as a TEDx talk, a Fast Company World Changing Idea, and now––a shout out in The New York Times Science section!
Amazing! Wait - what is C15:0?
C15:0 (aka pentadecanoic acid) is a healthy, odd-chain saturated fatty acid naturally found in whole fat dairy, as well as some fish and plants. C15:0 is the first essential fatty acid to be discovered since omega-3, which was over 90 years ago. Because pure C15:0 has been shown to have 3x the cellular benefits of the highest performing omega-3, C15:0 is emerging as the essential, essential fatty acid.
Numerous peer-reviewed studies have shown that people with higher C15:0 levels have better metabolic, heart, immune and liver health. Unfortunately, our C15:0 levels naturally decline as we age.
So, what did The New York Times say about C15:0?
The New York Times shares what dolphins can teach us about healthy aging, Excitedly, their coverage includes how fatty15's co-founder, Dr. Stephanie Venn-Watson, discovered that dolphins age at different rates. Perhaps more importantly, she found that a key biomarker of accelerated aging could be reversed when dolphins ate fish with higher C15:0.
What is a "biomarker of accelerated aging"?
Glad you asked! Hemoglobin is a component of our red blood cells that carries oxygen from our lungs to our tissues. Turns out that our hemoglobin levels may actually be a great indicator (aka, a biomarker) of an accelerated aging rate. In her study published in the Proceedings of the National Academy of Sciences, Dr. Venn-Watson found that fast-aging dolphins experienced a steady decline in hemoglobin over their lifetime. In contrast, slow-aging dolphins held relatively stable hemoglobin levels, even in their oldest years.
Guess what? Just like dolphins, declining hemoglobin is associated with less healthy aging in humans, too!
Okay, I get it. Declining hemoglobin can be a sign of faster aging. But where does C15:0 come in?
As highlighted in the New York Times, Dr. Venn-Watson showed that increasing dietary and body C15:0 levels effectively raises hemoglobin.
While that is great, here's where it gets super exciting. Beyond simply reversing a sign of faster aging, we now know that pure C15:0 does a bunch of good things at the cellular level to directly reverse cellular aging.*
And that's why we developed a pure, stable, sustainable, vegan-friendly and science-backed C15:0 ingredient for the world's first and only C15:0 supplement, fatty15.
Fatty15 to the rescue.
We age because our cells do. This process of cellular breakdown is defined by nine “hallmarks of aging”. Pure C15:0, found only in fatty15, has been shown to directly address at least four of these hallmarks.
Specifically, fatty15:*
- Strengthens our cells against age-related breakdown
- Repairs mitochondrial function, keeping our energy-producers going
- Naturally activates receptors (PPARs and AMPK) that regulate our metabolism, immunity, mood, sleep and appetite
- Keeps our DNA repair shops open, which keeps our cells properly functioning
Heck, that’s a lot of age-slowing action packed into one tiny capsule!
Elevate your cells. Elevate your self.
The bottom line.
In summary, science has shown that our C15:0 levels decline as we age, which in turn, can accelerate our age-related breakdown. The good news is that fatty15 can help restore our C15:0 levels and reverse aging at the cellular level.* With the recent New York Times story, our movement to improve global health - one person and dolphin at a time - is well underway.
