Nitric oxide is a chemical signaling molecule that helps your body regulate blood pressure, cardiovascular health and several other functions. It is produced naturally by the body, but you can also increase your level of nitric oxide by eating foods high in nitrates or taking supplements that contain nitric oxide precursor molecules.

During exercise, the body uses nitric oxide to help your muscles use more oxygen and produce more energy during your workout. It also increases glucose uptake in your skeletal muscle, which helps replenish glycogen that is depleted during exercise.

However, your body can only produce so much nitric oxide. So, if you want to make sure that your body is producing as much of it as possible, consider supplementing with nitric oxide precursor molecules like L-arginine or L-citrulline.

While nitric oxide is important for your heart and blood vessels, Fildena 150 can also have some serious side effects. These include blurred vision, indigestion or heartburn, nausea, headaches, and a stuffy nose.
