Human milk oligosaccharides are a complex group of indigestible carbohydrates that play a crucial role in the health and development of infants. They represent the third largest solid component of human milk, following fat and lactose. In colostrum, which is the first milk produced after childbirth, human milk oligosaccharides are found in concentrations ranging from 22-24 g/L. In mature milk, their levels typically range from 5-12 g/L.

The most significant and well-established application of 2'-Fucosyllactose is in infant formula. Since 2'-Fucosyllactose is a critical component of human milk, its inclusion in infant formula is designed to more closely mimic the composition of human milk. 2'-Fucosyllactose in infant formula provides several health benefits, including immune system support, gut health, protection from pathogens, etc.
