3'-Sialyllactose (3'-SL)

3'-Sialyllactose (3'-SL) is a vital human milk oligosaccharide (HMO) found in high concentrations in breast milk. Known for its sialic acid (Neu5Ac) structure, 3'-SL supports various health benefits, including immune function, gut health, and brain development. As one of the most studied sialylated HMOs, it plays a crucial role in early life development and offers prebiotic, anti-adhesive, and antimicrobial properties.

Product Highlights

  • Abundant in Breast Milk: One of the most prevalent sialylated oligosaccharides.
  • Promotes Cognitive Development: Supports brain health and language skills in infants.
  • Immune Support: Enhances the body's defense against harmful pathogens.
  • Gut Health: Modulates gut microbiota for improved digestive function.
  • Versatile Use: Ideal for dietary supplements and infant nutrition formulations.

Nutritional Benefits

3'-Sialyllactose offers a variety of health benefits that support both infant and adult wellness:

  • Immune Support: 3'-SL helps protect against harmful pathogens by inhibiting bacterial adhesion and supporting a balanced immune response.
  • Gut Health: It promotes gut integrity by regulating intestinal gene expression and fostering a healthy microbiota.
  • Cognitive and Brain Development: Sialic acid, a key component of 3'-SL, is essential for neuronal development, making this HMO beneficial for cognitive growth, particularly in infants.
  • Heart Health: 3'-SL enhances the sialylation of low-density lipoprotein (LDL), potentially reducing cardiovascular risks.
  • Bone Health: Studies suggest that 3'-SL can help prevent bone loss, offering potential benefits for bone health conditions like osteoporosis.
