Glucosamine is used to synthesise substances that form key structural components of cartilage
The sulphur form may promote the uptake of sulphur into cartilage
Chondroitin may be synthesised from glucosamine
Glucosamine Sulphate is a compound found naturally in connective tissues, cartilage, muscles, tendons, ligaments, spinal discs and heart valves.
Quest do not add chondroitin in the formula, the reason being that glucosamine itself will synthesise chondroitin. Also chondroitin is a large molecule which is not absorbed very well (especially in the elderly) and there is also no evidence to demonstrate that the combination of Glucosamine Sulphate and chondroitin will produce better results than Glucosamine Sulphate alone.
Quest Glucosamine Sulphate offers a unique guarantee of purity, potency and quality at every stage of production, thereby providing a reliable, safe and effective product in which you can be really confident.
