2'-Fucosyllactose (2'-FL) is one of the most abundant human milk oligosaccharides (HMOs) found naturally in breast milk. It plays a vital role in infant health by supporting the development of a healthy gut microbiome, enhancing the immune system, and protecting against harmful pathogens. As a prebiotic, 2'-FL selectively nourishes beneficial gut bacteria such as Bifidobacteria, which are essential for digestive health and nutrient absorption. Moreover, it mimics some of the protective functions of breast milk by preventing the adhesion of harmful microbes to the intestinal lining, thus reducing the risk of infections. Recent research also links 2'-FL to improved cognitive development and immune regulation in infants. Due to its unique biological properties and safety profile, 2'-FL is increasingly incorporated into infant formulas and nutritional supplements to replicate the benefits of natural breast milk for babies who cannot be breastfed.

2'-Fucosyllactose is primarily used in infant formula to closely mimic the composition and benefits of human breast milk. Its prebiotic properties promote a balanced gut microbiota, leading to better digestion and enhanced immune function in infants. Beyond infant nutrition, 2'-FL is being explored in dietary supplements aimed at supporting gut health and immunity for adults. It is also utilized in functional foods and beverages targeting digestive wellness and immune support. The ingredient’s proven safety and natural origin make it suitable for inclusion in a wide range of health-focused formulations, from baby nutrition products to wellness supplements designed to improve overall health and resilience.
