Description
D-Glucosamine hydrochloride is an amino sugar produced by microbial fermentation, crystallization and drying. As one of the best-established joint support supplement ingredients, it is formulated into capsules, tablets and powder drink mixes for cartilage and connective-tissue health — very often stacked with chondroitin sulfate, MSM and hyaluronic acid.
KEEP INGREDIENTS supplies glucosamine HCl bulk powder to USP specification, with a key commercial advantage: it is fermentation-derived and shellfish-free, which removes the crustacean-allergen and vegan-formulation blockers that traditional shellfish-derived glucosamine carries.
Our 80-mesh glucosamine hydrochloride is a white, free-flowing crystalline powder with low loss on drying (0.04%), tight specific rotation (+71.53°) and clean heavy-metal profile — ready to drop into joint-health capsules, tablets and stick-powder lines.

What Is Glucosamine HCl Used For?
As a leading joint health supplement ingredient, our fermented glucosamine hydrochloride is commonly built into:
• Joint and cartilage support capsules and tablets
• Glucosamine + chondroitin sulfate combination formulas
• Powder drink mixes for active adults and seniors
• Connective-tissue and mobility nutraceuticals
• Pet joint-health supplements
Because it is fermentation-derived and shellfish-free, it can be labeled as suitable for vegans and free of crustacean allergens — a decisive advantage for EU and US brands that need to avoid shellfish-derived raw materials.
