Glucosamine Sulfate 2NaCl meets USP monograph requirements for Glucosamine Sulfate Sodium — the accepted standard across North American, European, and Asia-Pacific supplement markets.
The sodium salt form of glucosamine sulfate is the dominant form in European supplement markets, supported by clinical research from European pharmacological studies.
Contains approximately 59–65% active glucosamine per gram — providing effective dosing in standard joint health capsule and tablet formulations.
Chloride content 11.8–12.8% and residue on ignition 22.5–26.0% provide verifiable markers confirming authentic 2NaCl salt form, not physical blends.
Freely soluble in water — ideal for tablet, capsule, and powder blend manufacturing as well as functional beverage applications.
COA, TDS, allergen declaration (shellfish), and source documentation available per batch to support global regulatory submissions.
The preferred glucosamine form for European market supplements, supported by long-standing consumer recognition and clinical efficacy documentation.
Classic dual-ingredient joint health formula combining with chondroitin sulfate — JointSource supplies both ingredients from a single source.
Used as the active ingredient in pharmaceutical drug products registered for joint health in EU member states where glucosamine is classified as a medicinal product.
Incorporated in joint protection supplements for active adults and athletes, often combined with MSM, collagen peptides, and anti-inflammatory botanicals.
Sodium-free potassium salt form preferred for low-sodium supplement formulations.
