Description

2'-Fucosyllactose (CAS NO 41263-94-9) is a structurally important human milk oligosaccharide (HMO) that plays a critical role in early-life nutrition and gut health. Its core value lies in its prebiotic function, selectively promoting the growth of beneficial gut microbiota such as bifidobacteria. This high-purity ingredient is essential for manufacturers in the infant formula, dietary supplement, and functional food industries seeking to enhance product nutritional profiles and mimic the benefits of human milk.

Application

• Infant Formula Fortification: A key functional ingredient added to infant and follow-on formulas to closely replicate the composition and health benefits of human breast milk.
• Dietary Supplements & Nutraceuticals: Used in adult and pediatric nutritional powders, capsules, and gummies to support digestive health and immune function.
• Functional Food & Beverage Production: Incorporated into yogurts, fermented drinks, and health bars as a premium prebiotic fiber to enhance gut microbiome diversity.
• Pharmaceutical Research & Development: Serves as a reference standard and active ingredient in clinical studies investigating gut-brain axis, immunity, and metabolic health.
• Microbiome & Probiotic Synbiotics: Combined with probiotic strains in synbiotic formulations to improve probiotic survival, colonization, and efficacy in the gastrointestinal tract.
• Cell Culture & Biochemical Research: Utilized in academic and industrial laboratories to study carbohydrate-mediated biological recognition, adhesion, and signaling pathways.
