Official title: Effect of Low Dose Galactose on Glycaemia and Glucose Kinetics
Run by University of Bath · NCT07599683 · Data updated 2026-11-12
Researchers will test whether adding a small amount of galactose with a 75 g glucose drink can help control blood sugar in healthy adults.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older who are normoglycemic, with BMI 18.5–30 kg/m2, and without metabolic, dietary, or gastrointestinal disorders that affect sugar metabolism.
✕Probably not a fit
Individuals with diabetes, prediabetes, metabolic diseases, galactose or fructose metabolism disorders, or those on ketogenic diets may not benefit.

What this trial studies
This interventional study uses a crossover design to compare glucose kinetics after a standard 75 g glucose load with and without galactose, and with fructose as a comparator. State-of-the-art dual stable isotope tracing will track how glucose enters the bloodstream, how the liver releases sugar, and how muscles take up glucose. The goal is to see if galactose slows glucose appearance from the gut or liver or enhances glucose disposal in tissues. Results will clarify whether galactose can modulate postprandial glycemia in normoglycemic adults. The study is led by the University of Bath with collaboration from the University of Birmingham and Arla Foods.
Why it matters
Potential benefit: If successful, galactose could be used to help manage post-meal blood sugar in healthy individuals or inform sugar formulation strategies.
How similar studies have gone: Previous studies using isotope tracing and sugar additives have shown signals of altered glucose kinetics, but this specific galactose-glucose interaction in normoglycemic adults is novel.
