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 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.
RECOMMENDED USAGE : As a dietary supplement take 2500mg with water or juice prior to physical activity or as directed by a physician.
