Nitric Oxide is a key molecule manufactured by the body which causes vasodilation. Vasodilation is an expansion of the internal diameter of the blood vessels. This, in turn, leads to increased blood flow, oxygen transport, delivery of nutrients to skeletal muscle and a reduction in blood pressure.
Supplementation with nitric oxide is known for producing several popular results among bodybuilders. The first of these is an increased recovery rate. It helps support the amount of blood flow to the tissues by encouraging the smooth muscles in the body to relax. This allows for more oxygen and nutrients to be delivered to the muscles which help boost recovery after an intense workout.
It is also important to note that an increased oxygen delivery to the muscles brought about by nitric oxide supplementation reduces lactic acid build-up and consequently fatigue which hinders progress in the gym. What this simply means is a person will be able to work out for a longer duration of time without feeling tired.
One more major benefit of taking supplements is an increased muscle pump. This will become particularly evident after a workout session because of the increased blood flow.
