3-Fucosyllactose (3-FL)

The HMO that increases in concentration over lactation for growing infants and toddlers

Gut health
Gut health3-FL promotes the growth of beneficial gut bacteria and strengthens the intestinal barrier, helping to protect against harmful pathogens. It may also help alleviate digestive discomfort and reduce symptoms such as constipation.
Immune health
Immune health3-FL supports the maturation of gut-associated lymphoid tissue (GALT), a key component of the immune system. Through this mechanism, it may help strengthen immune responses and improve overall immune resilience in infants.
Brain health
Brain healthBy promoting a balanced gut microbiota, 3-FL may help support healthy brain development and cognitive function through the gut–brain axis.
Product Detail

3-FL plays an increasingly vital role in late-stage infant development and beyond. Unlike other HMOs, the concentration of 3-FL in human milk rises significantly throughout the lactation period, offering unique benefits for gut health, pathogen defense, and immune system modulation.

Through precision fermentation, Cataya 3-FL is produced using Corynebacterium glutamicum, a safe, non-endotoxin-producing strain recognized as Qualified Presumption of Safety (QPS) by EFSA and Generally Recognized as Safe (GRAS) by the U.S. FDA. Our robust and scalable processes have been validated across multiple production scales, ensuring a consistent supply of the highest quality, purity, and reliability. Regulatory filings for Cataya 3-FL are actively progressing in multiple regions globally.
