The 10 Best L-Arginine Supplements for 2022

L-arginine supplements can be taken as capsules, powders, liquids, and pills.

L-arginine is one of the essential amino acids that the body needs. This conditionally necessary or semi-essential amino acid is utilized by the body to:

• produce proteins,
• maintain the urea cycle, and
• repair tissue.

Nitric oxide and citrulline, which are vasodilators, are produced during the conversion of L-arginine.

The proper operation of the immune system depends on it as a precursor to amino acids, such as glutamic acid, proline, and creatine. L-arginine helps mature T cells (type of white blood cells) that are essential for an immune response.

1. Improve exercise performance: By enhancing blood flow and boosting the availability of oxygen and nutrients to the muscles, L-arginine improves exercise performance.
2. Increase endurance: By encouraging the creation of creatine, L-arginine raises the level of nitric oxide in the body. Increased oxygen transport to the muscles and high energy levels brought on by creatine work together to promote endurance.
3. Encourage muscle pump: By increasing oxygenation and blood flow to the muscles, your muscles appear more toned and athletic.
4. Promote muscle recovery: L-arginine is a precursor to many amino acids, including ornithine, which helps the body eliminate nitrogenous waste. By lowering lactic acid buildup and preventing muscle exhaustion, this amino acid aids in recovery.
