Mechanism of action

1

Ileal brake activation

The emulsion is designed to deliver fat to the lower small intestine intact, triggering the ileal brake, a reflex that slows digestion and signals fullness.

2

Delayed fat digestion

Slower release of fatty acids prolongs satiety signaling from the gut to the brain.
