Mechanism

SNAC (oral semaglutide absorption enhancer)

What a GLP-1 receptor agonist actually does: which receptors it reaches, how it slows gastric emptying, and the satiety pathway it runs through.

What is SNAC (oral semaglutide absorption enhancer)?

Sodium N-(8-[2-hydroxybenzoyl] amino) caprylate, the absorption enhancer formulated alongside oral semaglutide in Rybelsus and Ozempic tablets.

It nudges gastric pH and loosens the cell membrane just enough for a peptide to cross; without it oral semaglutide absorption is effectively nil. That is the reason for the 30-minute fasting window, because food breaks the complex. Ask any seller offering “oral semaglutide” what they use in its place.
