Safe, allergen-free, and eco-friendly, 2'-FL is revolutionizing nutrition for all ages. Discover how this tiny molecule is reshaping gut health, immunity, and the future of food!

What Exactly is 2'-Fucosyllactose (2'-FL)?

2'-Fucosyllactose (2'-FL) is a type of human milk oligosaccharide (HMO), a prebiotic carbohydrate naturally found in breast milk. Structurally, it consists of a lactose molecule linked to a glucose sugar unit. As the most abundant HMO, 2'-FL plays a critical role in nurturing infant gut health and immune development. Unlike other sugars, it isn’t digested by the body but serves as food for beneficial gut bacteria like Bifidobacteria. Today, 2'-FL is synthetically replicated and added to infant formulas and adult supplements to mimic breast milk’s unique benefits.

Where Does 2'-FL Come From? Natural Sources and Production

Naturally, 2'-FL is exclusive to human breast milk, where it accounts for up to 30% of all HMOs. To make it accessible commercially, scientists use advanced fermentation techniques:

1. Microbial Fermentation: Specialized yeast or bacterial strains are engineered to produce 2'-FL.

2. Purification: The compound is isolated and refined to achieve pharmaceutical-grade purity.

3. Quality Testing: Final products undergo rigorous safety and efficacy checks.

This synthetic process ensures scalability while retaining the biological activity of natural 2'-FL.
