L-Arginine is a conditionally essential amino acid found in the diet. It is a dietary supplement used mostly by athletic people because it is the amino acid that directly produces nitric oxide via the nitric oxide synthase enzymes.
The standard pre-workout dose for L-arginine is 3-6g. To maintain elevated arginine levels throughout the day, arginine can be taken up to three times a day, with a combined dose total of 15-18g. Taking more than 10g of arginine at once can result in gastrointestinal distress and diarrhea.
Arginine is an amino acid involved in two regulatory cycles (urea and nitric oxide) and can be converted into a few other bioactive molecules such as creatine or agmatine to regulate the body. It is known as one of the more versatile amino acids in the human body.
RECOMMENDED USAGE : As a dietary supplement take 1-6 capsules with water or juice prior to physical activity or as directed by a physician.
