Description

L-Citrulline is a non-essential amino acid that plays a crucial role in the urea cycle and nitric oxide metabolism. Its primary commercial value lies in its use as a key ingredient in dietary supplements for sports nutrition and cardiovascular health, as well as in pharmaceutical intermediates. This product is essential for manufacturers in the nutraceutical, pharmaceutical, and functional food and beverage industries seeking a reliable, high-purity ingredient.

Application

• Sports Nutrition & Dietary Supplements: A core ingredient in pre-workout and recovery formulations for its role in nitric oxide production, which supports blood flow and exercise performance.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other compounds targeting metabolic and cardiovascular conditions.
• Functional Food & Beverage Fortification: Incorporated into health-focused drinks, powders, and food products to enhance their nutritional profile.
• Clinical Nutrition: Employed in medical nutrition products for specific dietary management and metabolic support.
• Cosmeceuticals: Used in topical formulations for its potential skin-conditioning and vasodilatory properties.
• Research & Development: Serves as a standard and reagent in biochemical research and diagnostic applications.
