What are nitric oxide (NO) supplements? Can they help you exercise longer? Do they really deliver “extreme muscle hardness” and “muscle growth activation” as promoted? ConsumerLab.com took a hard look at the science and clinical studies surrounding nitric oxide supplements.

First, to be clear -- these supplements don’t contain nitric oxide, which is a gas. They generally contain L-arginine, which can increase nitric oxide in the body – sometimes. Nitric oxide, in turn, potentially increases blood flow to muscles and other organs. But will it do that for you? And will that increase muscle size and/or athletic performance? It may depend on your physical condition.
