- People overwhelmingly prefer a once‑daily pill, but peptide drugs are ruined by stomach acid and enzymes and are poorly absorbed, so oral GLP‑1s have very low bioavailability and require huge doses that make them expensive.
- Scientists solved injectables by changing the peptide and adding a fatty tail so the drug resists breakdown and sticks to albumin, which gives long lasting, effective once‑weekly shots that oral versions still struggle to match.
- A promising shortcut is to engineer edible microbes like spirulina to produce and hide GLP‑1 inside cell walls, which could protect the peptide and slash purification costs to make affordable oral pills — though safety, regulation, and public acceptance remain hurdles.
