Arginine (Arg) is a basic amino acid. Under physiological conditions, adults can generally achieve endogenous synthesis through the conversion of other amino acids such as glutamic acid, and its plasma concentration in the human body is normally maintained at approximately 100?μmol/L.

Market demand keeps climbing. According to PW Consulting, the global nitric-oxide supplement market reached around USD 1.02?billion in 2025 and is projected to hit USD 1.74?billion by 2032, representing a compound annual growth rate (CAGR) of about 8.01%. L-Arginine accounts for 42.5% of the total market share, with sports-nutrition applications making up as high as 57.5%. By regional breakdown, North America leads the global market with a 41.3% share, followed by the Asia-Pacific region at 21.2%. Driven by rising health awareness in China and India, the Asia-Pacific region registers one of the fastest growth rates worldwide. Expanding fitness populations and growing demands for health management are jointly fueling the rapid expansion of this market.

As an essential component of cytoplasmic and nuclear proteins, arginine not only participates in the synthesis of body proteins, glutamine and polyamines, but also serves as a precursor for multiple substances including urea, nitric oxide (NO) and creatine, playing vital roles in daily physiological activities.

Daily diet remains the primary source of arginine. Adults ingest approximately 4-6?grams of arginine from food each day, of which around 60% enters systemic circulation. Arginine is abundant in meat, dairy products, eggs, nuts and other foods.

L-Arginine delivers multiple health benefits:

Athletic performance: boosts blood circulation, improves blood-oxygen supply, and supports exercise endurance as well as post-workout recovery;

Bodily nutrition: supplies amino-acid nutritional foundations for normal physiological functions;

Tissue metabolism: participates in human amino-acid metabolism and maintains healthy tissue conditions.
