Could a gut hormone and amino acid combo prevent low blood sugar in diabetes?
NCT ID NCT06881472
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at how two substances—GIP, a natural gut hormone, and alanine, an amino acid from protein—work together to release glucagon, a hormone that raises blood sugar. Researchers tested 10 people with and without type 1 diabetes to see if combining GIP and alanine boosts glucagon more than either alone. The goal is to understand how this might protect against low blood sugar in type 1 diabetes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Glucose-dependent Insulinotropic Polypeptide (GIP) and alanine
- What this could lead to
- If successful, this research could point toward new ways to help people with type 1 diabetes avoid dangerously low blood sugar by boosting glucagon release.
- What could go wrong
- This is a very small, early-stage study with only 10 participants, so results may not apply broadly. It is designed to gather knowledge, not to test a treatment.
