Description

Potassium L-Aspartate is the potassium salt of the amino acid L-aspartic acid, a high-purity biochemical essential for advanced nutritional and pharmaceutical formulations. This compound serves as a critical source of bioavailable potassium and aspartate, supporting vital metabolic and physiological functions. It is primarily utilized by manufacturers in the nutraceutical, pharmaceutical, and food & beverage industries seeking a soluble, well-tolerated mineral supplement ingredient.

Application

• Nutraceutical & Dietary Supplements: As a key ingredient in electrolyte replacement products, sports nutrition formulas, and potassium supplements for its superior bioavailability and compatibility.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as an excipient or active component in parenteral and oral electrolyte solutions.
• Food & Beverage Fortification: For the nutritional enhancement of functional foods, medical nutrition products, and beverages requiring a soluble potassium source without a metallic aftertaste.
• Cell Culture Media: Acts as a component in specialized microbiological media and cell culture formulations, providing essential nutrients for growth.
• Biochemical Research: Employed as a standard or reagent in enzymatic studies, metabolic research, and biochemical assays.
