Since I reached 50, I’ve tried at least a dozen anti-aging supplements, searching for the magical solution that could help me turn back time and maintain my overall health. But then it hit me—most longevity brands promise impossible results in a bottle rather than addressing what causes aging.
That’s why fatty15 caught my attention. At first, I worried that it wasjust another trend claiming to be science-backed. But the more I read, the more I realized fatty15 isn’t about hollow messaging. It’s built on years of research and focuses on the root cause of aging: our cells.
A closer look at the research and reviews brings everything into focus. It’s easy to see why over 100,000 of people, including women navigating midlife, have already made fatty15 part of their daily routine.
Here Are 9 Things I Wish I’d Known About Fatty15 Sooner:
1. Healthy aging starts at the cell
Fatty15 takes a foundational approach to wellness. Every system in the body (metabolic, immune, cognitive, and beyond) depends on healthy cells. By supporting the strength and resilience of the cell membrane, fatty15 helps the body defend against age-related breakdown over time.*
It’s not hype; it’s about addressing aging at its foundation rather than chasing surface-level symptoms like most supplements do.
2. It’s an emerging essential fatty acid many diets lack
The key ingredient is pentadecanoic acid (C15:0), an odd-chain saturated fatty acid increasingly recognized as a foundational nutrient, meaning we need it to support healthy growth and development when we’re young, as well as our long-term health as adults.
Compared with the past, our modern diet contains very little C15:0, and fatty15 is the only patented supplement providing a pure, consistent source.
3. The first of its kind in over 90 years
C15:0 is being validated as the first essential fatty acid to emerge since Omega-3s over 90 years ago!
While Omega-3s help keep cell membranes flexible, fatty15 actually helps support and stabilize cell membranes. This is why it’s considered a foundational nutrient for cellular health.* Fatty15 delivers it in a clean, odorless, vegan-friendly form that’s designed to work at a regular, low daily dose.* Plus, no fishy aftertaste!
4. The discovery came from 10+ years of scientific research
Veterinary epidemiologist, Dr. Stephanie Venn-Watson, discovered that higher dietary and circulating levels of C15:0, a hidden nutrient, consistently predicted better health and resilience in aging dolphins. And when dolphins were given diets higher in C15:0, biomarkers of their red blood cell and cardiometabolic health improved.
That observation led to 10+ years of Office of Navy-funded research,100+ peer-reviewed studies, and over 60 patents, proving that fatty15 is truly grounded in science.
5. It supports 36+ cellular benefits
Fatty15 isn’t about dramatic overnight changes, but subtle improvements that compound with daily use. In a survey of 6,243 customers, 70% reported feeling or seeing benefits within 16 weeks, including:*
- More energy & vitality: Increased energy, motivation, and overall well-being.
- Improved sleep & calmer mood: Deeper, more consistent sleep and feeling less stressed.
- Clearer thinking: Reduced brain fog and improved mental clarity.
- Positive lab results: Some users report improvements in their routine lab tests relevant to metabolic, liver, and red blood cell health after consistent use.*
Fatty15 functions as a long-term resilience supplement, rather than a quick fix.* That’s what sold me on the subscription. It shows up when I need and I know I’m supporting my cells in a sustained way.
6. It’s been shown to support key metabolic and longevity pathways
I was surprised that C15:0 supports multiple pathways in the body that support many systems, from metabolic and liver health to cognitive function, immune response, and red blood cells.*
Research has shown that it helps strengthen cell membranes while also supporting important metabolic pathways involved in glucose balance, insulin function, and overall organ health.*
7. The results are measurable and evidence-based
The great thing about fatty15 is that you can measure it. C15:0 levels can be checked through a fatty acid blood panel or an at-home test, like Genova Diagnostics. So you can track your progress with hard data.
8. Fatty15 has won 20+ awards
Fatty15 has racked up more than 20 awards across a variety of categories since being launched in 2021. This is a fantastic recognition of its science-backed approach and the impact it’s having on people’s wellness, such as…
