Maternal Betaine Supplementation During Breastfeeding

Source: ClinicalTrials.gov · Last updated 24 Mar 2026

Brief summary (registry, in English)

Developing more efficient and cost-effective prevention strategies to slow down the worldwide epidemic of obesity and chronic metabolic disease has become a public health imperative. Our previous results in humans demonstrate that lower breast milk betaine levels were associated with faster infant postnatal growth, a strong and potentially modifiable risk factor of future obesity. Betaine is a trimethylated derivative of glycine, which is present in multiple foods and occurs naturally in breast milk. In this study, we will perform a double-blind randomized placebo-controlled pilot clinical study, in which maternal diet will be supplemented with betaine for 3 months during breastfeeding; infant's growth and adiposity will be monitored until 12 months of age, and breast milk composition and gut microbiota analyzed. An additional follow-up visit will be conducted at 48 months of age to repeat microbiome analysis, determine adiposity, and perform cognitive development assessment.
