First seen Apr 28, 2026 · Last updated Jun 21, 2026 · Updated 9 times
Summary
This small pilot study tested whether taking metformin 30 or 60 minutes before a meal changes how the body absorbs carbohydrates. One person with obesity and high blood sugar completed three sugar-drink tests, with metformin given at different times or not at all. The goal was to see if pre-meal timing improves the drug's effect on sugar absorption and digestion.
