Blood circulation is a vital function for transporting oxygen and nutrients to all the horse's cells. The bloodstream also has the important task of transporting away carbon dioxide and waste products from the cells. With age, this transport system often begins to function worse in both horses and humans. It can lead to what we call "age ailments" such as muscle stiffness, joint pain and impaired recovery, to name a few examples. The condition of the blood vessels is very important for blood circulation. The nitric oxide molecule is a prerequisite for an elastic and functioning blood vessel.

A healthy elastic blood vessel contributes to good blood circulation as it stretches and contracts as the blood passes.

If a horse has swollen legs, you want to get the blood circulation going to bring down the swelling. If a horse has joint pain, it often means that there is inflammation in the joint. Good blood circulation is a prerequisite for the inflammation to heal. Endurance and recovery depend on how quickly and efficiently an individual's heart and lungs can oxygenate and transport out oxygenated blood and energy to muscles and organs, as well as to transport away lactic acid, carbon dioxide and waste products from muscles and cells. Nitric oxide contributes to this in a very positive way.

Competition horses are exposed to great stress and optimal blood circulation is a prerequisite for long-term competition without injuries and convalescence times.
