This compound, the name of which many people will hear several
times during the course of their lives but be unaware of what is
actually is, is one of the most important vehicles for human
survival. Nitric oxide (NO) is defined as a colorless, toxic gas
obtained from the oxidation of nitrogen. It is a molecule that
emerges when a nitrogen atom combines with an oxygen atom.
Intense research over the last 20 years has revealed that this
molecule plays a fundamental role in inter-cell communication.
Nitric oxide is a hormone naturally manufactured in the human
body, in other words, a chemical messenger. It plays a strategic
role in the regulation of the vital functions of the nervous,
circulatory, defense, respiratory and reproductive systems. One
of the places where nitric oxide undertakes this important duty
is in our veins. Thanks to the perfect molecule nitric oxide,
requirements that vary according to different environments in
the body are met. The way the blood vessels expand during sport
