The important thing to know about Arginine is that it is converted into nitric oxide (NO) in the body. Why do we care about NO as a bodybuilder? Well, because NO is involved in, among other things, the process of vasodilation, which is the process that increases blood flow to muscles. Supplementing with L-Arginine can provide you with some terrific pumps in the gym, as a large amount of blood is forced into the muscles, allowing for better delivery of nutrients and oxygen. Since I’ve started supplementing with Arginine, I feel like my muscles are about to pop they are so full and pumped during my workout. It’s great! As the icing on the cake, Arginine can also help to boost growth hormones as well.
Dosage: Take 3-5 grams in the morning, before workouts and at bedtime. Arginine works best when taken on an empty stomach so try to take it an hour before a meal or a pre-workout protein shake.
