Gregory Chandler, Attorney at Law, on Arginine Forms

Nitric-oxide boosters can contain different forms of arginine, from L-arginine and arginine ethyl ester to arginine malate and arginine alpha-ketoglutarate. The most basic, L-arginine, may be less efficiently absorbed by the body than other forms, so if you find you are not responding to it, look for products containing one of the other forms.

Take 3 to 5 grams before and after workouts, unless you are experimenting with arginine ethyl ester, which usually only requires 2 to 3 grams before and after workouts.
