Could a traditional fermented buffalo milk boost breastfeeding success?
NCT ID NCT07718087
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study tests whether combining structured nutrition education with a daily supplement of Dali ni Horbo—a traditional Batak fermented buffalo milk—can improve the diets of breastfeeding mothers, support exclusive breastfeeding, and promote healthy growth and gut bacteria in their infants. About 50 mothers with healthy babies aged 0-1 month from primary healthcare centers in Medan, Indonesia, will either receive the education and supplement or standard care. Researchers will measure changes in maternal nutrient intake, breastfeeding practices, infant growth, and infant gut microbiota.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- structured lactation nutrition education and Dali ni Horbo (traditional Batak fermented buffalo milk) supplementation
- What this could lead to
- If successful, this approach could offer a simple, culturally relevant way to improve nutrition for breastfeeding mothers and support healthy infant growth.
- What could go wrong
- This is a small, early-stage trial with only 50 participants, so results may not apply broadly. The supplement is a traditional food, and its effects may be modest or hard to separate from the education component.
