The Glucosamine Series encompasses a range of high-purity amino monosaccharides, primarily including Glucosamine Hydrochloride (HCI), Glucosamine Sulfate (potassium or sodium stabilized), and N-Acetyl-D-Glucosamine, each produced through advanced hydrolysis and refinement technologies to ensure superior quality and consistent particle size. As fundamental building blocks for the biosynthesis of glycosaminoglycans and proteoglycans, these compounds play an essential role in maintaining cartilage structure, synovial fluid viscosity, and overall joint integrity. Widely recognized for their efficacy in supporting cartilage repair, reducing joint discomfort, and improving mobility, they are extensively utilized in dietary supplements, functional foods, and veterinary formulations. Their excellent compatibility with complementary ingredients such as chondroitin sulfate, MSM, and hyaluronic acid makes them the cornerstone of comprehensive joint health regimens targeting long-term musculoskeletal wellness, inflammation modulation, and active aging support.
Main Product type:
| Glucosamine Hydrochloride (GHCl) | Glucosamine Sulfate (GS) |
| Glucosamine combined with hydrochloric acid to form a salt. Molecular Formula: C₆H₁₃NO₅·HCl | Glucosamine combined with sulfuric acid to form a salt. Typically stabilized as a double salt (e.g., Glucosamine Sulfate Sodium Chloride/Potassium Chloride complex). |
• Extremely High Purity: Conventional processes can achieve over 99% purity. • High Active Ingredient Content: Glucosamine (the physiologically active unit) accounts for approximately 83.1%, meaning more active ingredient per unit weight. • Good Stability: Stable at room temperature, not prone to moisture absorption and degradation. • Pure Excipients: Does not inherently contain high concentrations of sodium or potassium ions. | • Contains Inorganic Salts: Must be combined with sodium chloride or potassium chloride in a double salt form for chemical stability. Therefore, finished products contain a certain amount of sodium or potassium ions. • Lower Active Ingredient Content: Glucosamine accounts for approximately 62.8%. • Complex Formulation: Pure Glucosamine Sulfate is unstable; formulation technology (e.g., crystalline structure control) significantly impacts product efficacy. |
The Absolute Mainstream for Global Dietary Supplements (Health Products). • Widely used for daily joint care and relieving osteoarthritis symptoms. • Often combined with ingredients like Chondroitin Sulfate, MSM, and Hyaluronic Acid. | The Mainstay for Pharmaceuticals in Specific Countries/Regions. • In Europe, particularly in countries like Italy and France, it is often used as a prescription drug for treating osteoarthritis. • Some clinical studies suggest it may have more significant effects on improving knee joint symptoms. |
