What Is N-Acetyl-D-Glucosamine?
N-Acetyl-D-Glucosamine is the N-acetylated form of D-glucosamine and is commonly sourced as GlcNAc or NAG powder for supplement manufacturing.
N-Asetil-D-Glukozamin is a defined amino sugar derivative with an acetyl group attached to the glucosamine molecule. In B2B supplement sourcing, it is commonly searched as NAG, GlcNAc, N-Acetyl Glucosamine, N-Acetylglucosamine or 2-Acetamido-2-deoxy-D-glucose. Buyers usually evaluate NAG by source, CAS number, assay, identity method, HPLC purity, specific rotation, pH, loss on drying, residue on ignition, particle size, bulk density, solubility, residual solvents, heavy metals, microbiology, allergen statement, vegan or shellfish-free statement, packaging, storage condition and destination-market label requirements.
Defined Ingredient Identity
Confirm CAS 7512-17-6, chemical name, HPLC identity, formula, molecular weight and actual batch COA before supplier approval.
Source & Allergen Review
NAG may be linked to shellfish chitin or non-shellfish fermentation routes, so source and allergen status should be confirmed by batch.
Supplement Supply Focus
Gensei supports supplement brands, OEM factories and contract manufacturers with bulk NAG sourcing and technical documentation.

Common questions from supplement brands, OEM manufacturers, contract manufacturers and ingredient buyers.
N-Asetil-D-Glukozamin nedir?
N-Acetyl-D-Glucosamine is an N-acetylated glucosamine derivative also known as NAG or GlcNAc. In supplement raw material sourcing, it is commonly evaluated by source, CAS number, assay, identity, particle size, residual solvents, heavy metals, microbiology and batch COA.
What is the CAS number of N-Acetyl-D-Glucosamine?
The CAS number commonly used for N-Acetyl-D-Glucosamine is 7512-17-6.
What is the molecular formula of N-Acetyl-D-Glucosamine?
The molecular formula commonly referenced for N-Acetyl-D-Glucosamine is C8H15NO6, with molecular weight around 221.21 g/mol.
Is NAG the same as GlcNAc?
Yes. NAG and GlcNAc are common abbreviations for N-Acetyl-D-Glucosamine or N-Acetylglucosamine. Buyers should still confirm exact chemical identity and batch specification.
Is N-Acetyl-D-Glucosamine the same as glucosamine?
No. N-Acetyl-D-Glucosamine is the acetylated form of glucosamine. Glucosamine HCl and glucosamine sulfate are different ingredient forms with different CAS references, molecular weights and label declarations.
Is N-Acetyl-D-Glucosamine shellfish free?
Not automatically. NAG may be linked to shellfish chitin or produced through non-shellfish routes. Buyers should request source declaration, allergen statement, shellfish-free statement and cross-contact information before making shellfish-free claims.
Is N-Acetyl-D-Glucosamine vegan?
Vegan suitability depends on source route, precursor, fermentation substrate, processing aids and manufacturing conditions. Buyers should request a vegan statement if vegan label positioning is required.
Is N-Acetyl-D-Glucosamine water soluble?
N-Acetyl-D-Glucosamine is generally water soluble or water dispersible depending on grade and test conditions. Finished formulas should be tested for clarity, pH, taste, active uniformity and stability.
Can NAG be used in capsules or tablets?
Yes. NAG can be evaluated for capsules and tablets when serving size, bulk density, flowability, particle size, compression behavior and stability are suitable.
Can NAG be used in gummies?
NAG can be evaluated for gummy concepts, but heat, pH, taste, texture, moisture, active retention and packaging should be tested carefully before launch.
Can NAG be used in drink powders?
NAG can be evaluated for drink powders, sachets and stick packs. Formulators should review solubility, pH, flavor compatibility, aftertaste, moisture protection and active retention.
Can NAG be combined with glucosamine, chondroitin or MSM?
Yes. NAG can be evaluated in joint support blends with glucosamine, chondroitin sulfate, MSM, sodium hyaluronate, collagen peptides or botanicals after formula and label review.
What quality indicators should be checked?
Buyers should review source, assay, identity, HPLC purity, specific rotation, pH, loss on drying, residue on ignition, particle size, bulk density, residual solvents, heavy metals, microbiology, allergen status and batch COA.
What documents can I request before ordering?
Qualified B2B buyers can request COA, specification sheet, SDS, TDS, source declaration, allergen statement, shellfish-free statement where applicable, vegan statement where applicable, non-GMO statement, residual solvent report, flow chart, stability information and other technical files depending on the selected grade.
