I got a prescription with arginine 3g and glutamine 2g DT 20 powders. Should arginine-base as prescribed orally be taken to 3g? Or should this be arginine hydrochloride?

What Is the Correct Arginine Dosage? The appropriate dosage of L-arginine may vary depending on your reason for taking it. According to the Mayo Clinic, there are no established amounts of arginine that are recommended for adult human dosing; A common oral dose is two to three grams, three times a day, maxing at about nine grams in a 24-hour period.
