Granular form with PVP K-30 or HPMC carrier — assay ≥ 95.0%, LOD ≤ 2.0%, heavy metals ≤ 10 ppm. Suitable for direct compression tablet manufacturing. Contact us for DC grade specifications.
Glucosamine HCl contains approximately 83% active glucosamine per gram — the highest among all glucosamine salt forms, enabling smaller capsule/tablet size at equivalent dosing.
Meets USP monograph for Glucosamine Hydrochloride — the primary standard for the North American supplement market and the most widely used glucosamine form in the US.
Less moisture-absorbing than sulfate forms — excellent manufacturing stability in tablet and capsule production with reduced caking and flow issues.
Residue on ignition ≤ 0.1% — the lowest ash content among all glucosamine forms, confirming the pure HCl salt without additional stabilizing salts.
Direct compression granular grade (with PVP K-30 or HPMC carrier) available for tablet manufacturers requiring direct compression processing without wet granulation.
COA, TDS, MSDS, allergen declaration (shellfish), and heavy metal test report available per batch.
The dominant glucosamine form in the US supplement market — standard ingredient in joint health tablets, capsules, and powder formulas.
The high active glucosamine content (83%) allows 1,500 mg glucosamine dose in fewer or smaller tablets compared to sulfate forms.
The standard combination joint health formula in the US market — JointSource supplies all three active ingredients from a single source.
Widely used in canine and feline joint health chews, soft chews, and treats — the preferred form for veterinary joint supplement manufacturers.
Common sodium-stabilized sulfate form for standard joint health capsules.
