Description

L-Arginine L-Malate is a high-purity, non-hygroscopic salt formed from the amino acid L-Arginine and malic acid. This compound is valued for its enhanced stability and bioavailability compared to the free amino acid, making it a superior ingredient for demanding nutritional and pharmaceutical formulations. It is primarily sought by manufacturers in the dietary supplement, sports nutrition, and pharmaceutical industries for its role in supporting nitric oxide production, cardiovascular health, and muscle metabolism.

Application

• Sports Nutrition & Performance Supplements: A key ingredient in pre-workout and recovery formulas for its vasodilatory and anti-fatigue properties.
• Cardiovascular Health Supplements: Used in formulations aimed at supporting healthy blood pressure and circulation through nitric oxide synthesis.
• Pharmaceutical Intermediates: Serves as a stable and pure active pharmaceutical ingredient (API) or excipient in various medicinal products.
• Clinical Nutrition: Incorporated into medical foods and enteral nutrition products for specific metabolic support.
• Functional Food & Beverage Fortification: Added to health drinks, bars, and fortified foods to enhance their nutritional profile.
• Cosmetic Applications: Utilized in topical formulations for its potential skin-conditioning and revitalizing benefits.

Quality Control

Our L-Arginine L-Malate is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) are provided with every shipment, detailing specifications for identity, assay, and impurity profiles. We can supply grades compliant with relevant pharmacopeial monographs (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
