What Is L-Arginine? How Can L-Arginine Help Me?

L-arginine is a naturally occurring amino acid that may help to increase blood flow (in some populations) and anabolic growth-hormone secretion. This helps increase lean muscle mass/strength/power, promotes faster recovery from exercise, and improves the work capacity of active muscles. 

L-arginine also improves the process of clearing waste products from your muscles. This may result in a reduced sense of fatigue. 

When Should I Use L-Arginine?

L-arginine should be consumed as part of your post-exercise recovery, which should begin within 30 minutes of finishing your workout. Some people like to take arginine in the pre-exercise period (30-60 min before exercise).

How Much L-Arginine Do I Need?

The amount of L-arginine needed to increase anabolic growth-hormone secretion and improve muscle recovery is at least 6 grams as part of your post-workout recovery. The typical American diet only provides about 5.5 grams of L-arginine during an entire day.

More Helpful Information

L-arginine functions as a precursor to nitric oxide, a potent vasodilator that allows increased blood flow. L-arginine is also involved in the synthesis of urea, a waste product produced by the body. Urea is synthesized in the liver and is ultimately excreted by the kidneys in the urine.
