Prebiotic drink may tame After-Meal blood sugar spikes
NCT ID NCT06714552
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a prebiotic supplement called galacto-oligosaccharide (GOS) can lower blood sugar spikes after eating. Fifty healthy adults will drink either a GOS supplement or a glucose control beverage, and their blood sugar and insulin levels will be measured over several hours. The goal is to see if replacing some digestible carbs with this prebiotic can help prevent the sharp rises in blood sugar that are linked to diabetes and heart disease.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Galacto-Oligosaccharide (GOS) prebiotic supplement
What this could lead to
If it works, this could point toward a simple dietary supplement to help manage blood sugar spikes after meals, potentially reducing the risk of diabetes and heart disease.
What could go wrong
This is a small, early-stage trial in healthy adults, not people with diabetes. The effect may be small or not translate to real-world meals. It only tests a single drink, not long-term use.
