Complementary Sialylated HMO
6'-SL should be presented beside 3'-SL. Together they help nutrition companies build a more complete sialylated HMO story inside a multi-HMO product.
Sialylated HMO
6'-Sialyllactose Sodium Salt (6'-SL)
6'-Sialyllactose Sodium Salt helps nutrition companies round out sialylated HMO sourcing. It is often reviewed together with 3'-SL when brands want to compare sialylated structures or add more HMO diversity to a formulation concept.
Nutrition companies usually review technical data, sodium contribution, quality documents, application direction, and factory-visit needs before moving to commercial supply.
- Complements 3'-SL for sialylated HMO portfolio sourcing

- Batch residue testing for technical and quality review

Application and Regulatory Review
6'-SL Application, Use-Level, and Regulatory Review
Review 6'-SL application direction, use-level references, permitted categories, labelling points, and destination-market requirements before sampling, quotation, or commercial formulation.
Early-Life and Sialic-Acid Research
6'-SL supports early-life R&D and sialic-acid-related formulation discussion. We keep the wording scientific and avoid finished cognitive claims.
Adult Functional Nutrition Concepts
6'-SL can also support premium supplement and active-lifestyle nutrition concepts. We use this as an early-stage R&D angle that needs market-specific evidence and claims review.
Sodium Salt Technical Review
Because 6'-SL is supplied as a sodium salt, formula teams should review sodium contribution, moisture, assay basis, impurity profile, and target product matrix before sampling.
EU Novel Food Review
EU 2021/82 authorises 6'-SL sodium salt as a novel food, and EU 2023/2215 gives a newer source-specific 6'-SL sodium salt authorisation. Nutrition companies should review source-specific conditions and labelling requirements before launch.
U.S. GRAS Review
The FDA GRAS Notice Inventory includes 6'-SL sodium salt entries with 'no questions' response letters, including GRN 881, GRN 922, GRN 1016, GRN 1053, GRN 1075, and GRN 1275. GRN 1169 was ceased at the notifier's request, so we do not use it as support.
Use-Level Review Notes
- FDA GRN 1275 lists 6'-SL sodium salt for non-exempt infant formula for term infants up to 0.40 g/L and formula for young children over 12 months up to 0.5 g/L, as consumed.
- FDA GRN 1275 lists other food categories at maximum levels up to 125 g/L. Treat those as category-specific references that require serving-size and exposure review.
- EU entries for 6'-SL sodium salt show infant formula levels around 0.4 g/L to 0.7 g/L, depending on the authorised source.
- EU follow-on formula entries show around 0.3 g/L to 0.7 g/L in final product ready for use.
- EU food supplement entries include 1.0 g/day to 1.8 g/day, with restrictions for infants and young children.
- For blend projects, review the combined sialylated HMO level and same-day-use labelling.
