Nitrogen and oxygen make up the small molecule NO, nitric oxide.  “Little but mighty” could be used to describe what this little molecule can do!

Produced by our bodies, nitric oxide is made from an amino acid called arginine combined with a family of enzymes.  And, actually, when arginine and the enzymes mix, nitric oxide is formed as a reaction.  Another beneficial amino acid, citrulline, is also produced as a byproduct of this process.

One of the biggest benefits of this little molecule is that it triggers relaxation and widening in the blood vessels.  This vasodilation in turn increases blood flow to the heart and provides strong support for healthy blood pressure.  Indeed nitric oxide is a tiny, magical molecule that can honestly be described as little but mighty!
