The Science

A naturally occurring molecule at the heart of satiety.

Oleoylethanolamide (OEA) is a lipid mediator produced in the small intestine after eating. It is one of the body's own signals in the regulation of appetite, energy balance and metabolic wellbeing.

From capsule to small intestine

How OLEACORE™ is designed to work

Educational visualization: the ultramicronised OEA is suspended in a refined olive oil lipid carrier for delivery in the duodenum, where OEA is naturally produced after meals.

Satiety signalling

How OEA signals appetite regulation

Once released, OEA joins one of the body's own post-meal conversations — from the gut lining, to the PPAR-α receptor, to the brain via the vagal pathway.

Educational visualization of published research on OEA signalling. OLEACORE® is a dietary supplement, not a treatment for any disease.

1. Produced after eating

Cells lining the small intestine synthesise OEA from dietary fats, particularly oleic acid — the main lipid in olive oil.

2. Activates PPAR-α

OEA binds the PPAR-α receptor, a key regulator of fatty-acid oxidation and metabolic gene expression in liver, muscle and fat tissue.

3. Signals satiety

It communicates with the brain via afferent nerves to support the natural feeling of fullness and healthy eating patterns.

Research foundation

Two decades of peer-reviewed OEA science.

OEA wasn't invented by a supplement brand. It was discovered in academic laboratories and characterised across more than twenty years of published research into satiety signalling, appetite regulation and gut–brain communication.
