Dosage information
The standard preworkout dose for arginine is 3–6 grams.
Taking more than 10 grams of arginine at once can result in gastrointestinal distress and diarrhea, but it is possible to maintain elevated arginine levels throughout the day by taking three spaced doses (15–18 grams/day). However, citrulline supplementation is more effective at maintaining elevated arginine levels for long periods of time.
