N-Acetyl-L-Carnosine (NAC)  ·  High-Purity Peptide Raw Material  ·  B2B Bulk Supply

N-Acetyl Carnosine is a naturally occurring acetylated dipeptide derived from beta-alanine and L-histidine. Compared to standard carnosine, the acetyl group confers greater enzymatic stability against carnosinase, making it a preferred ingredient for nutraceutical, cosmetic, and ophthalmic raw material applications. We supply pharmaceutical-grade NAC powder in bulk quantities with full documentation and cold-chain compliance.

Industry applications
