A New Era in Nutritional Science:
The Discovery of C15:0
For decades, saturated fats have been categorised as "bad," but scientific advancements in lipid research have begun to change that narrative.
Among these developments was the rediscovery of C15:0 (pentadecanoic acid) – an odd-chain saturated fatty acid found in some whole-fat dairy products and certain plants and fish.
C15:0 had largely gone unnoticed until veterinary epidemiologist Dr Stephanie Venn-Watson identified its potential significance while studying ageing in dolphins.
Through the use of metabolomics, a cutting-edge analytical technique, Dr Venn-Watson observed that dolphins with higher levels of C15:0 tended to exhibit markers associated with healthier ageing patterns. This sparked a wave of further investigation into the role of C15:0 as a trace nutrient in humans.

From Discovery to Innovation:
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.

Introducing Fatty15:
