Description

L(-)-Carnitine Hydrochloride is the biologically active, levorotatory enantiomer of carnitine, a quaternary ammonium compound essential for fatty acid metabolism. This high-purity salt form offers superior stability and solubility, making it a critical ingredient for demanding pharmaceutical and nutraceutical formulations. It is primarily required by manufacturers in the dietary supplement, clinical nutrition, and pharmaceutical industries for its role in energy production and cellular transport processes.

Application

• Dietary Supplements & Sports Nutrition: A key active ingredient in weight management formulas, energy boosters, and products aimed at improving exercise performance and recovery by facilitating the transport of long-chain fatty acids into mitochondria.
• Pharmaceutical Preparations: Used in injectable and oral formulations for the treatment of primary and secondary carnitine deficiencies, and in metabolic support therapies.
• Clinical & Infant Nutrition: Incorporated into parenteral nutrition solutions and specialized infant formulas to ensure adequate carnitine levels for proper development and metabolic function.
• Functional Food & Beverages: Fortified into health drinks, nutrition bars, and other functional food products to enhance their metabolic health claims.
• Cosmetic & Personal Care: Utilized in topical formulations for its potential antioxidant properties and role in skin cell energy metabolism.
• Research & Biochemical Reagents: Serves as a high-purity standard and reagent in life science research, diagnostic kits, and enzymatic studies.
