Description

L-Arginine L-Glutamate is a high-purity, pharma-grade salt formed from the essential amino acid L-Arginine and the amino acid L-Glutamic acid. This compound matters for its role as a stable and bioavailable source of both amino acids, crucial for supporting metabolic and physiological functions. It is needed by manufacturers in the pharmaceutical, nutraceutical, and high-end food supplement industries for formulating products aimed at cardiovascular health, athletic performance, and metabolic support. Our supply ensures consistent quality and reliable global availability for your production needs.

Application

• Pharmaceutical Intermediates: Used in the synthesis of advanced parenteral nutrition solutions and metabolic support drugs.
• Dietary Supplements: A key active ingredient in premium sports nutrition, nootropic, and cardiovascular health formulations for enhanced bioavailability.
• Clinical Nutrition: Incorporated into medical nutrition products and amino acid infusion solutions for hospital and clinical use.
• Biochemical Research: Serves as a critical reagent and standard in life science research and cell culture media preparation.
• Cosmeceuticals: Found in advanced skincare products for its potential role in promoting collagen synthesis and skin barrier function.

Quality Control

Our L-Arginine L-Glutamate is manufactured under strict quality management systems. Each batch is tested to meet high-purity standards suitable for pharmaceutical and nutraceutical applications, with specifications aligning with industry pharmacopoeial guidelines. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to ensure full traceability and compliance for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
