Glucosamine, an essential amino monosaccharide derived from chitinous biomass, serves as a primary substrate for the synthesis of glycosaminoglycan chains in human cartilage. While naturally occurring in the body, its commercial production primarily involves the chemical or enzymatic degradation of shellfish waste. This review evaluates the efficacy of its four prevalent forms; glucosamine, glucosamine hydrochloride, glucosamine sulphate, and N-acetyl glucosamine with a focus on their therapeutic mechanisms. Specifically, glucosamine derivatives manage osteoarthritis and rheumatoid arthritis by promoting cartilage repair and exerting potent anti-inflammatory effects, while also showing promise in treating cardiovascular, neurological, and dermatological conditions. Despite its $3.5 billion global market value, industrial production faces significant feasibility challenges, including the high cost of enzymatic processes and the environmental impact of chemical deacetylation waste. Furthermore, while generally recognized as a safe dietary supplement by the USFDA, clinical application must account for potential allergenic reactions in individuals with shellfish sensitivities and monitor long-term toxicological profiles to ensure patient safety.
