Summary

This small pilot study looked at whether taking metformin before a meal (30 or 60 minutes prior) affects how the body absorbs carbohydrates. Researchers tested this in one obese person with prediabetes or type 2 diabetes using sugar-drink tests. The goal was to understand if timing could make metformin work better, while also checking for stomach side effects.
