The applications of arginine extend far beyond its role as a basic nutrient, demonstrating a broad range of potential in various fields. In the field of medicine and health, arginine is a key component of the classic intravenous medication “Compound Amino Acid Injection,” which is used for clinical nutritional support in conditions such as liver disease and postoperative recovery. Its potential in cardiovascular health has also attracted significant attention. In the realm of functional foods and health supplements, arginine is a core ingredient for boosting immunity, improving microcirculation, combating fatigue, and serving as a nutritional supplement for athletes. It helps promote the secretion of growth hormones and supports recovery and vitality after exercise. In Special Medical Purpose Formula Foods (FSMPs), arginine, as a conditionally essential amino acid, is used in nutritional intervention programs for individuals with specific medical conditions. In animal nutrition, arginine is crucial for the growth and development of young animals and is an important additive in high-quality feeds. As a functional amino acid, arginine shows clear potential in promoting plant growth, enhancing stress resistance, and improving the quality of agricultural products, offering innovative directions for the development of advanced green agriculture and special fertilizers.
