D-Glucosamine Sulfate Potassium Chloride

The stabilized sulfate salt of glucosamine, complexed with potassium chloride to achieve crystalline stability and shelf life. The dominant form of glucosamine used in the European veterinary and human supplement markets, where most published clinical evidence in osteoarthritis was generated using sulfate-based material.

White to off-white crystalline powder with high water solubility. Delivers approximately 65 percent glucosamine activity per gram (versus 83 percent for the HCl form), with the trade-off being broader regulatory acceptance in EU veterinary product registrations.

We supply pet-grade and pharmaceutical-grade D-Glucosamine Sulfate Potassium Chloride from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production. Shellfish-derived and corn-fermentation (shellfish-free) sources available on request.

Common market grades include shellfish-derived 2KCl complex at 98 percent assay, corn-fermented 2KCl complex for hypoallergenic pet diets, and the sodium-chloride-stabilized variant for finished products requiring potassium-free declarations.

Bulk and reduced-MOQ shipments. Batch-level COA covering assay, glucosamine free-base content, KCl content, heavy metals, and microbiology.

D-Glucosamine Sulfate Potassium Chloride was developed in the 1980s as a stabilized crystalline form of glucosamine sulfate, which on its own is hygroscopic and not shelf-stable. The 2:1 stoichiometric complex with potassium chloride locks the sulfate salt into a crystalline lattice that handles, ships, and tablets reliably.

The clinical evidence base supporting glucosamine in osteoarthritis was generated predominantly with the sulfate form, which is why EU regulatory pathways for veterinary medicinal products tend to specify sulfate-form material in product registrations. The HCl form dominates the North American supplement channel for cost and label-claim reasons, while the sulfate form dominates the EU veterinary medicinal channel.

Industrial production proceeds either by acid hydrolysis of shellfish chitin followed by sulfation and KCl complexation, or by microbial fermentation of corn glucose for shellfish-free product lines. Both routes yield material meeting the standard 98 percent assay specification.

Veterinary safety data in dogs, cats, and horses at supplement-level dosing is well-established. AAFCO supplement classifications in North America and corresponding feed-additive frameworks in the EU, UK, Japan, Australia, and New Zealand accommodate the ingredient with standard label disclosures.
