High Purity L-Arginine Powder | ≥98% Feed, Food & Supplement Grade | CAS 74-79-3
Description:
Product Overview
L-Arginine is a conditionally essential amino acid that plays a central role in protein synthesis, nitric oxide production, and metabolic regulation. As the primary physiological precursor to nitric oxide (NO), it acts as a vasodilator, helping relax blood vessels and improve blood flow throughout the body. This unique mechanism underpins its wide-ranging applications in cardiovascular health, sports nutrition, immune function, and metabolic support.
At Henan Liyin Biotech, we supply high-purity L-Arginine in the form of a white crystalline powder, with a minimum purity of ≥98% (typically 98.5–101.5% on dried basis), compliant with USP, EP, and FCC standards. Our product is available in Feed Grade, Food Grade, and Supplement Grade to serve applications across animal nutrition, human food, dietary supplements, and personal care.

- Multi-Standard Compliance: Meets USP, EP, and FCC specifications, providing global regulatory acceptance.
- Complete Traceability: Each batch is accompanied by a comprehensive Certificate of Analysis (COA), including testing for purity, heavy metals, and microbiological contaminants.
- Flexible Packaging: Available in packaging options from 1kg to bulk quantities to suit your production needs.
Key Functional Properties
Nitric Oxide Production & Cardiovascular Support
L-Arginine serves as the exclusive precursor for nitric oxide (NO) synthesis. NO is a critical signaling molecule that relaxes blood vessels, supporting healthy blood pressure levels and cardiovascular function. Research suggests L-arginine may help reduce blood pressure and improve symptoms of angina and peripheral arterial disease.
Sports Performance & Recovery
As a key amino acid in protein synthesis, L-Arginine supports muscle function and exercise performance. It plays a role in growth hormone release and may help reduce recovery time after exercise.
Mitochondrial & Metabolic Health
Recent research published in Cardiovascular Diabetology (2024) demonstrated that L-Arginine supplementation improves mitochondrial function, increases PGC-1α levels, and supports mitochondrial biogenesis and antioxidant capacity. These findings suggest potential benefits for metabolic health and energy homeostasis.
Growth & Immune Support
L-Arginine is essential for growth and development in young animals and humans. It stimulates the release of growth hormone, supports immune function, and plays a role in wound healing and tissue repair.
Weight Management
A 2025 meta-analysis published in Biomedicine & Pharmacotherapy found that L-Arginine supplementation significantly reduced waist circumference and total body weight, with doses exceeding 15g/day showing more pronounced effects.
Quality Assurance & Documentation
All batches undergo rigorous quality control, including:
Assay by HPLC: ≥98.0% (typical results 98.5–101.5%)
Heavy Metal Screening: Lead ≤ 5 ppm, Arsenic ≤ 2 ppm
Microbiological Testing: For safety and purity
Specific Rotation and pH: Verified against USP/EP/FCC specifications
We provide complete documentation with every shipment, including Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and Allergen Statement.
Sourcing Support
We offer flexible packaging and can provide samples for pre-shipment testing. Our technical team is available to assist with grade selection (Feed, Food, or Supplement Grade), application guidance, and custom formulation support — from R&D trials to full-scale commercial production.

L-Arginine is a conditionally essential amino acid that serves as the primary precursor for nitric oxide (NO) synthesis. By boosting NO production, it supports healthy blood flow, vascular function, and cardiovascular health. In sports nutrition, it promotes exercise performance, muscle function, and recovery. In animal feed, it enhances growth, immunity, and reproductive performance in swine, poultry, and aquaculture. With applications spanning dietary supplements, functional foods, and personal care, L-Arginine is a versatile, science-backed ingredient for multiple industries. Available in Feed, Food, and Supplement Grades with ≥98% purity.
