The Development of FA15™
While naturally present in foods like butter, whole milk, and some fish, typical modern diets tend to be low in C15:0 — especially among individuals who avoid full-fat dairy or consume predominantly plant-based diets. To make this molecule more accessible, researchers set out to develop a pure, sustainable, and vegan-friendly form of C15:0.
The result is FA15™ — a proprietary, science-backed ingredient that delivers pure C15:0 in a stable, bioavailable format. FA15™ is produced through a precision fermentation process starting with sustainably sourced, plant-based ingredients, ensuring both quality and consistency while avoiding reliance on animal products.

FAQs
What is C15:0?
C15:0 (pentadecanoic acid) is a trace odd-chain saturated fatty acid found in small amounts in whole-fat dairy and certain types of fish. It’s currently being studied for its potential role in human health. Fatty15 offers a pure, vegan-friendly source of C15:0 — designed for simple, consistent use in your daily wellness routine.
Can’t I just get C15:0 from food?
While C15:0 is found naturally in trace amounts in some foods, intake from diet alone can vary significantly — especially for those following plant-based, low-fat, or dairy-free eating patterns. Fatty15 provides a consistent and pure daily source in a vegan-friendly capsule.
How does Fatty15 compare to omega-3 supplements?
Omega-3s and C15:0 are different types of fatty acids. Omega-3s are polyunsaturated fats, while C15:0 is a saturated fat with a unique structure. Unlike omega-3s, which are more prone to oxidation, C15:0 is stable and shelf-friendly. Fatty15 comes in small, tasteless vegan capsules — with no fishy aftertaste or odour.
Can I test my C15:0 levels?
While C15:0 isn’t commonly included in standard blood tests, some functional or integrative health practitioners may offer fatty acid panels that include it. If you're curious about your C15:0 status as part of a broader wellness review, we recommend speaking with a qualified healthcare provider who can guide you through appropriate testing options.
Is Fatty15 suitable for vegans?
Yes – Fatty15 is 100% vegan and contains no animal-derived ingredients.
