Arginine

L-arginine is a semi-essential amino acid because we can produce arginine ourselves from glutamine, glutamic acid, and proline. Our daily diet contains various sources of arginine, such as dairy, fish, meat, grains, legumes, nuts, and seeds.

Arginine is a precursor of nitric oxide (NO), urea, and ornithine. It is necessary for the body's own synthesis of creatine and can also be used for the formation of citrulline. Therefore, it plays an important role in the so-called urea cycle.

L-arginine supplements are best taken on an empty stomach. Most supplements contain 500 mg of arginine per capsule.

Through our diet, we consume approximately 4,400 mg of arginine daily. Most clinical studies have been conducted with dosages between 7,000 and 15,000 mg per day.
