Product Introduction
L‑Arginine base powder is a free‑form, neutral‑pH crystalline amino acid naturally present in dietary proteins and synthesized endogenously from L‑citrulline via the urea cycle. It acts as a direct physiological precursor to nitric oxide (NO), creatine, glutamate, and proline, supporting multiple core metabolic pathways.
As a key physiological precursor substance, L-Arginine Base participates in the synthesis of nitric oxide, creatine, proline and collagen in vivo. It effectively regulates nitrogen balance, accelerates ammonia metabolism and excretion, maintains normal endothelial vascular function, and supports tissue repair and basic protein synthesis.

Frequently Asked Questions
Q1: What is the difference between L‑Arginine Base and L‑Arginine HCl?
-
A: L‑Arginine Base is the neutral free‑form amino acid with higher L‑arginine content (~100% basis). L‑Arginine HCl is an acid‑salt form with lower molar L‑arginine content and acidic pH. Base form is preferred for pH‑sensitive formulations and clean‑label products.
Q2: What is the recommended shelf life and storage?
-
A: Shelf life is 24 months when stored unopened in a dry, cool area (<25°C), protected from direct sunlight and moisture. Reclose tightly after opening to prevent caking and degradation.
Q3: Is this product suitable for vegan/vegetarian formulations?
-
A: Yes. Our L‑Arginine Base Powder is produced via microbial fermentation, free of animal‑derived ingredients, and suitable for vegan and vegetarian formulations.
Q4: Can I get a sample and COA before ordering?
-
A: Yes. We provide complimentary test samples with a full COA, MSDS, and specification sheet upon request to verify purity, identity, and compliance before bulk purchase.
