Try to get the Arginine in a powder form also. It gets into your blood stream faster and we all know that fast acting is better. The taste isn't good at all but it's alright if you mix it with any kind of juice. 1 scoop of an Arginine powder supplement is usually 1 serving which is commonly 5 grams. I suggest taking one serving in the morning, one serving before you workout, and one 3-4 hours before bed...
