Could a prebiotic from breast milk boost your gut health?
NCT ID NCT06570330
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested whether a daily prebiotic supplement called SuperHMO, made from sugars found in breast milk, could improve gut health in healthy adults. Thirty-two participants took either the supplement or a placebo for 30 days. Researchers measured changes in gut bacteria and markers of inflammation to see if the supplement had any effect.
