Description
Glucosamine Sulfate Product Overview
Glucosamine (C6H13NO5, CAS 3416-24-8 for the base) is an amino sugar found in cartilage and in the chitin of crustacean shells. Pure glucosamine sulfate is very hygroscopic and unstable, so commercial material is stabilized with potassium chloride (2KCl) or sodium chloride (2NaCl). It is a white crystalline powder that is freely soluble in water.
In several European countries, crystalline glucosamine sulfate is registered as a medicinal product, and pharmaceutical companies use it in powders for oral solution and tablets. Producers of nutritional products use it in tablets and capsules, under the regulations of each market. Shellfish-derived and fermentation-derived grades are available.
Glucosamine hydrochloride is listed separately as D-Glucosamine HCl; it contains more glucosamine per gram and needs no stabilizing salt. Ingredients often combined with glucosamine include Chondroitin sulfate, Dimethylsulfone and Collagen peptide.

Frequently Asked Questions
Why is glucosamine sulfate stabilized with KCl or NaCl?
The pure grade is unstable and very hygroscopic. Forming a double salt with potassium or sodium chloride makes it stable for production.
What is the difference from glucosamine hydrochloride?
The hydrochloride contains more glucosamine per gram and needs no stabilizer, while the sulfate is the form registered as a medicine in some European countries.
How can I get a price and documents?
