Product Overview

L-Arginine (CAS 74-79-3), commonly known as L-Arginine base, is a conditionally essential alkaline amino acid for human metabolism. It serves as a key precursor for nitric oxide production in the human body and is widely applied in sports nutrition formulations. It helps support blood flow, physical endurance and post-exercise recovery, making it a popular ingredient for dietary supplements targeting athletic performance and cardiovascular health. It can also be incorporated into functional food fortification and used as raw material for clinical amino acid infusions and pharmaceutical nutritional preparations.

Industrial L-Arginine is produced by mature microbial fermentation technology. Using corn starch and glucose as primary raw materials, the production process includes deep liquid fermentation, filtration, ion exchange, concentration, crystallization and multi-step purification to obtain high-purity finished products with stable batch quality for large-scale supply. It complies with the standards of USP, CP, BP, EP, AJI, and FCC.

 

Character

 

L-Arginine is white free-flowing crystalline powder, odorless with a slightly bitter taste. It has good water solubility and stable physicochemical properties under normal temperature and dry conditions. The product features high purity, low impurity content and good powder fluidity, convenient for mixing and formulation in supplement and food production. It is stable under proper storage and not easy to agglomerate.

 

Main Functions

1.Blood Flow & Endurance Support: Acts as nitric oxide precursor, supports blood circulation, improves physical endurance and accelerates recovery after exercise for sports nutrition formulas

2.Cardiovascular Nutritional Support: Provides nutritional support for cardiovascular health and maintains normal vascular function in dietary supplement products

3.Immune & Tissue Health: Supports healthy immune function and tissue repair for human nutritional supplementation

4.Clinical Nutrition Raw Material: Used for amino acid infusion and parenteral nutrition preparations in pharmaceutical industry

 

Main Applications

1.Sports Nutrition & Dietary Supplements (Primary): Widely added into athletic performance supplements, cardiovascular health nutrition formulas

2.Functional Food: Applied in functional food fortification to supplement amino acid nutrition

3.Pharmaceutical Industry: Raw material for clinical amino acid injection and rehabilitation nutritional preparations

4. Raw Material for L-Citrulline Production: Serves as an important precursor in L-citrulline manufacturing for downstream nutraceutical and pharmaceutical supply chains.
