Like with any supplement, there are always potential side effects and there are reports of nitric oxide side effects too.
But what is nitric oxide anyway?
Fortunately, nitric oxide is a naturally produced gas in the body so you aren’t introducing anything new. You are just adding a larger amount through the use of supplements. So the side effects are relatively small and are usually just minor headaches.
Taking nitric oxide supplements is simply a great way to get more nitric oxide into the body. This will allow the blood to flow better and increase the amount of energy you have. You can then use this extra energy to workout harder, for longer and increase your muscle size.
