As a very health-conscious person, supplements have always been a key part of my daily routine. One of those has been fish oil pills – I’d read that they help with inflammation and vitamin D absorption, so I’ve been incorporating them since.

Recently, though, I came across new research on another essential fatty acid, C15:0 – the “first essential fatty acid to be discovered since the omegas” and thought, do I really need an omega-3 alternative? What’s all the buzz about fatty15? How can this benefit me?

I want to help answer all that and more for you – what C15:0 is, how it compares to other fatty acid supplements, the benefits it can provide, and if it’s worth it to include fatty15 in your daily supplements.


TLDR; Is Fatty15 Legit?

C15:0 (also called pentadecanoic acid) is clinically proven to boost cellular health significantly more than even the purest omega-3 supplements. But it’s not just another omega-3 supplement – it’s better, broader, and safer at repairing cells and restoring cellular health.



It’s now the third recognized essential fatty acid and is the single ingredient in fatty15’s daily supplement created to promote healthier cells, improve metabolic, heart, and liver health, and protect against aging-related breakdown.

Faty15 Pros + Cons


Near-term benefits: Better sleep, calmer mood, less anxiety, more energy, less hungry – can be felt within the first few weeks of taking.


Long-term benefits: Improves cellular resilience, promotes healthy skin, glucose levels, and cholesterol levels, and supports liver, metabolic, heart, immune, and red blood cell function.


Vegan: Unlike many omega-3s, fatty15 is vegan, tasteless, and odorless (no fish burps!!). Also, lactose and gluten-free with no preservatives.


Higher quality: You know exactly what you’re getting, where many omega-3 supplements vary in quality, levels of fish oil, contaminants, shelf-life, and smell, plus they negatively impact ocean life.


Longer shelf life: Doesn’t include oils that oxidize over time, so they won’t rancid in the bottle or in your body (like many omega-3 supplements)


Scientifically Validated: Breakthrough discovery backed by a robust collection of more than 50 reliable, peer-reviewed scientific studies.


Limited Availability: You can’t buy fatty15 at local grocery stores or pharmacies on demand. It is currently only available through Fatty15’s website directly.


Synthesized Product: The single ingredient in fatty15 (FA15™) isn’t sourced from fish. It was, however, carefully synthesized to mimic the exact properties of pentadecanoic acid (C15:0) while being >99.5% pure, environmentally sustainable, vegan-friendly, more bioavailable, and meeting diverse dietary needs.
