Nitric oxide (NO) is a molecule that is naturally produced in the body, which aids communication between cells via the transmission of signals throughout the entire body. Production of nitric oxide in the body occurs through the breakdown of the amino acid, arginine by enzymes. NO is a potent vasodilator that helps relaxes veins, allowing more oxygen and nutrients to flow through the circulatory system. Nitric oxide plays vital roles in controlling the circulation of blood and regulating the pressure by dilating the arteries.
Nitric oxide has also been shown to be vital in some cellular activities, such as helping to boost brain function and improving memory by transmitting information between nerve cells in the brain, reducing inflammation, improving sleep quality, and assisting the immune system.
