Premium-purity crystalline L-lysine hydrochloride — the industry standard for high-performance feed and pharma use.
Product Overview
L-Lysine HCL (98.5%) is the purified crystalline form of the essential amino acid L-lysine, produced by fermentation, ion-exchange purification, evaporation, and crystallisation. The resulting white free-flowing crystals meet the strictest purity and identity requirements of major regional pharmacopoeias.
Compared to our lysine sulphate grade, HCL offers higher concentration (98.5% vs 51% sulphate), cleaner appearance, and zero residual fermentation solids. It is the preferred form for premium feed premixes, amino-acid infusion solutions, and food-grade fortification.
Available in both feed-grade (GB 8245) and pharmaceutical-grade (USP / EP / JP / CP) specifications.
Key Features
Minimises dosage and premix bulk.
USP, EP, JP, CP monographs on request.
Uniform crystal size enables precise automated dosing.
Pure crystallised active — no colour, odour, or carry-over.
HCL form stable over wide pH range — pharma-compatible.
Registered with feed and pharma authorities in 40+ countries.
