3-FL (3-fucosyllactose)
3-FL consists of three glucose molecules and one focal molecule. Research has shown that the concentration of 3-FL in breast milk increases during lactation, and it is considered important for the development of the immune system in newborns and infants, while also providing protection against various pathogens.
3-FL has been approved for use in various foods and beverages such as infant formula, beverages, dairy products, etc. in the United States and the European Union.
