Description

L-Arginine Mono-D-Galacturonate is a high-purity, pharmaceutically relevant salt formed from the amino acid L-arginine and D-galacturonic acid. This compound is valued for its enhanced stability and bioavailability compared to its individual components, making it a critical ingredient in advanced nutraceutical and pharmaceutical formulations. It is primarily sought after by manufacturers in the dietary supplement, functional food, and cosmeceutical industries seeking to leverage the synergistic benefits of arginine and galacturonic acid.

Application

• Nutraceutical & Dietary Supplements: As a key active ingredient in formulations targeting cardiovascular health, immune support, and athletic performance due to the combined nitric oxide precursor (arginine) and prebiotic fiber derivative (galacturonate) actions.
• Functional Food & Beverage Fortification: For enrichment of health-focused drinks, bars, and meal replacements where improved solubility and stability are required.
• Pharmaceutical Intermediates: Serves as a building block or active pharmaceutical ingredient (API) in the synthesis of more complex therapeutic agents.
• Cosmeceutical & Skincare Products: Incorporated into serums and creams for its potential skin barrier repair and moisturizing properties attributed to the amino acid and sugar acid moieties.
• Research & Development: Used in biochemical and pharmacological studies investigating cell signaling, nutrient transport, and glycobiology.
