Nitric oxide Ingredients
By Alan E. Shugarman, M.S., R.D.
If you’re like me, you love to get in the gym and feel your muscles swell to eye-popping proportions during your workout. You crave that intense shirt-ripping pump because you know you’re getting a great workout. That’s where the NO factor comes in!
When I say NO, I actually mean nitric oxide (NO), one of the hottest sports nutrition supplements around today. Everyone wants to know if and how it works and if there are any studies backing up its effectiveness.
In the human body, NO is an important signaling molecule that acts in many tissues to regulate various physiological processes including vasodilation (blood vessel expansion), brain neuron function, inflammation, apoptosis (programmed cell death), cellular protection, immune function and erection. Viagra actually works on the NO pathway. For our purposes, we are most interested in the vasodilation effects for increasing blood flow to the muscles and for erectile function. 
As you train, blood flows into your muscles causing a pump. NO products are focused on increasing your natural muscle pump. Weight trainers love to feel their muscles pumped because they know they are working the muscle and can “feel” it. The theory behind NO products is if you can get more blood into the muscles, you will have a greater pump effect and possibly better nutrient delivery. Many people believe the better the pump, the better the workout. The purpose of NO products is to increase the pump, causing your muscles to look and feel larger. Some proponents have tried to stretch NO’s impact to include increased strength as well, but several studies have shown it does not affect strength or number of weight-lifting reps. These same studies did not evaluate such areas as muscle size, pump, feel or perceived quality of a workout—the very benefits that have made NO products so popular in the marketplace.
If you’re looking for that extra muscle pump in the gym, here are some of the most popular NO boosting ingredients, so you gain a better understanding of how they work.
