Nitric Oxide, a key molecule manufactured by the body, causes
vasodilation (an expansion of the internal diameter of blood
vessels), which in turn leads to increased blood flow, oxygen
transport, delivery of nutrients to skeletal muscle, and
a reduction in blood pressure. An amino acid compound called
arginine alpha-ketoglutarate (A-AKG) and arginine-ketoisocaproate
(A-KIC) can boost short term Nitric Oxide levels.
