Oral Semaglutide
Oral formulation of semaglutide with SNAC absorption enhancer — the compound behind Rybelsus — for oral GLP-1 research.

Overview
Oral Semaglutide is the tablet formulation of semaglutide co-formulated with SNAC (sodium N-[8-(2-hydroxybenzoyl)amino]caprylate), an absorption enhancer that enables gastrointestinal uptake of the peptide. Marketed as Rybelsus by Novo Nordisk, it was the first oral GLP-1 receptor agonist to receive regulatory approval. Recent clinical data from the OASIS 1 trial with a higher 50mg dose showed up to 17.4% weight loss — approaching the efficacy of injectable semaglutide. The oral formulation removes the injection barrier while maintaining the established semaglutide pharmacological profile.
Mechanism of Action
SNAC creates a localised increase in gastric pH around the tablet, protecting semaglutide from pepsin degradation while promoting transcellular absorption across the gastric epithelium. Once absorbed, oral semaglutide acts identically to injectable semaglutide — binding GLP-1 receptors to stimulate insulin secretion, suppress glucagon, delay gastric emptying, and activate hypothalamic satiety centres. The C-18 fatty di-acid modification enables albumin binding, extending the half-life to support once-daily oral dosing. Bioavailability is approximately 1% — low but sufficient due to high receptor potency.
Research Applications
