Product Description
L-Arginine hydrochloride, primarily used as a pharmaceutical raw material and food additive, is an amino acid-based drug. Its active ingredient, L-arginine, participates in the ornithine cycle, promoting the conversion of blood ammonia to urea, thus lowering blood ammonia levels, treating hepatic coma, aiding wound healing, and stimulating the immune system. It is also a substrate for nitric oxide synthase, acting as a vasodilator. Storage should avoid contact with strong oxidants; gloves and other protective equipment are recommended during handling.

What are the benefits?
Cardiovascular Health Support
- Blood Pressure Regulation
As a precursor to nitric oxide (NO), L-arginine hydrochloride promotes NO production. NO relaxes vascular smooth muscle, dilates blood vessels, and reduces peripheral vascular resistance, helping to maintain stable blood pressure and potentially providing some auxiliary antihypertensive effects for hypertensive patients.
- Improvement of Vascular Endothelial Function
Helps repair and protect vascular endothelial cells, reducing vascular inflammation and the risk of atherosclerosis, and lowering the likelihood of thrombosis.
Immune Regulation
- Promotes the activity and function of immune cells such as macrophages and lymphocytes, enhancing the body's defense against pathogens and helping to accelerate recovery after infection, surgery, or trauma, reducing infectious complications.
Wound Healing Promotion
- Participates in collagen synthesis, providing essential amino acid raw materials for wound healing, helping to accelerate wound repair and reduce the risk of infection, especially beneficial for patients with chronic wounds or burns.
Metabolic Regulation
- May improve glucose metabolism and insulin sensitivity, helping to stabilize blood sugar levels and reduce the risk of complications in patients with type 2 diabetes or metabolic syndrome.
Neuroprotection
- In cases of brain injury, cerebral edema, etc., increasing cerebral blood flow and reducing oxidative stress can promote neuronal survival and repair, and may have a certain effect on improving cognitive impairment in elderly people with hypertension and poor health.
Application directions
Medical Applications
- Lowering Blood Ammonia: Participates in the ornithine cycle, promoting the conversion of blood ammonia to urea, suitable for hepatic coma (especially unsuitable for patients receiving sodium infusions) and liver diseases such as hepatitis and cirrhosis.

- Liver Protection: Helps prevent and treat fatty liver disease.
- Promoting Wound Healing: Accelerates tissue repair by stimulating the immune system and collagen synthesis.
- Vasodilator: As a substrate for nitric oxide (NO) synthase, it generates NO, dilates blood vessels, improves blood circulation, and has potential benefits for cardiovascular health (such as coronary heart disease, hypertension, and erectile dysfunction).
- Hormonal Regulation: Can stimulate the secretion of insulin, growth hormone, etc., and helps regulate protein synthesis and metabolism.
Food and Nutrition Applications
- Nutritional Fortifier: Used in special medical purpose formula foods, infant and elderly nutritional powders to supplement semi-essential amino acids.
- Food additives: As flavoring agents, they undergo a Maillard reaction with sugar to produce aroma compounds, meeting the permitted flavoring standards of GB 2760-2001.
- Sports nutrition: Added to protein powder and energy drinks, the recommended dosage is 1%~5%, which can delay fatigue, promote muscle recovery, and improve athletic performance.
