Glucosamine is an amino sugar (aminomonosaccharide) that occurs naturally in the body as a building block within certain connective-tissue structures. In food supplements it is most commonly used as glucosamine sulfate or glucosamine hydrochloride, often stabilised as a salt with sodium chloride or potassium chloride, and presented as tablets, capsules, powders, or sachets. The raw material may be sourced from marine materials (e.g., crustacean shells) or produced via microbial fermentation, depending on the manufacturer and purity specifications. On labels it may also appear as “glucosamine sulfate sodium chloride” or “glucosamine sulfate potassium chloride”, which describe stabilised sulfate forms. In cosmetics, glucosamine-related derivatives may be used as functional ingredients in water-based formulas, while supplements typically focus on oral dose forms. Products frequently combine it with other ingredients from the same category, such as chondroitin, and declare the amount either as the salt form or as a glucosamine equivalent.
