The 2KCl form uses potassium chloride as the stabilizing salt — completely sodium-free, meeting the needs of consumers managing sodium intake due to hypertension or cardiovascular conditions.
Meets USP monograph for Glucosamine Sulfate Potassium Chloride — accepted in North American, European, Australian, and Asian supplement markets.
The absence of significant yellow flame reaction (sodium test) provides analytical confirmation that the product is a genuine potassium salt form, not a physical blend.
Contains approximately 56–60% active glucosamine per gram — comparable dosing performance to the 2NaCl form in standard supplement formulations.
The 2KCl form is the dominant glucosamine sulfate specification in European and Australian supplement markets, with strong consumer recognition.
COA, TDS, allergen declaration (shellfish), and sodium-free certification documentation available per batch.
The ideal glucosamine sulfate form for products targeting consumers with hypertension, heart disease, or low-sodium dietary requirements.
The preferred specification for European and Australian joint health supplements, meeting local pharmacopoeia and regulatory preferences.
Used in low-sodium or sodium-free labeled health food and supplement formulations where sodium content must be declared or minimized.
Combined with chondroitin sulfate (bovine or marine) in sodium-free joint health supplement formulations.
Common sodium-stabilized sulfate form for standard joint health capsules.
