Arginine: A complete guide to this essential amino acid

Arginine is a semi-essential amino acid that plays an important role in the production of nitric oxide, a compound that promotes vasodilation. It is particularly prized by athletes for its benefits on blood circulation and endurance.

1. What is arginine?

Arginine is a conditionally essential amino acid, which means that although the body can synthesize it, dietary intake may be necessary in cases of increased need (e.g. intense physical activity).

2. Benefits of arginine

• Increased blood flow: By stimulating nitric oxide production, arginine helps blood vessels dilate.
• Enhanced sports performance: It can increase endurance and reduce fatigue.
• Immune support and healing: Promotes tissue repair and strengthens the immune system.

3. Recommended dosage

Recommended doses range from 3 to 6 grams a day, taken before training or spread throughout the day. We recommend starting with a low dose and gradually increasing.

4. Side effects and precautions

At high doses, arginine may cause nausea, stomach pain or bloating. In case of cardiovascular disease or gastrointestinal disorders, consult a physician before use.
