How Important Is L- Arginine For Muscle Gain?
There is a connection between L- Arginine and bodybuilding, over the past 10 years or so, L- Arginine has remained one of the most successful muscle building supplement ingredients out there.
It is the primary composite found in most pre-workout “nitric oxide supporters”, with the primary forms being l arginine AKG, L- Arginine HCl and regular L- Arginine.
The thought is that since L- Arginine is a precursor to nitric oxide, and since nitric oxide is a potent vasodilator (meaning it widens the blood vessels), L- Arginine supplementation will promote blood flow to the working muscles for enhanced power, endurance, and recovery.
But beyond the hyped up marketing and anecdotal reports, what does the basic science say regarding L- Arginine supplementation? Are there any existing L- Arginine advantages for bodybuilders?
