Overall health may be benefitted by the molecule Nitric Oxide. Nitric Oxide’s role in maintaining health had largely been ignored until recent discoveries of its many roles. In 1992 Nitric Oxide was named Molecule of the Year by the American scientific community. The 1998 Nobel Prize in Medicine or Physiology was awarded to Robert F. Furchgott, Ferid Murad, and Louis J. Ignarro for their discoveries of the role of nitric oxide in cardiovascular physiology as a critical signaling molecule. In all mammals, nitric oxide is responsible for many physiological changes.
