Oral Semaglutide vs Semaglutide
The same molecule in two delivery routes — and why the oral dose is so much larger.
The short answer: Identical active compound; oral bioavailability is roughly 1%, so the tablet dose is far higher.

How they differ
These are not two compounds. Both are semaglutide. The difference is entirely one of delivery.
Peptides are destroyed by stomach acid and poorly absorbed across the gut wall. The oral formulation co-formulates semaglutide with SNAC, an absorption enhancer that raises local pH and helps the molecule cross the gastric epithelium. Even so, bioavailability sits around 1%, which is why oral doses are expressed in milligrams where subcutaneous doses are in fractions of a milligram.
Absorption is also highly sensitive to conditions — food and fluid in the stomach markedly reduce it, which introduces a variability that the subcutaneous route does not have.
