Citrulline is an amino acid used as a booster for bodybuilding sessions. It can also be consumed as citrulline malate, which is citrulline linked to malic acid. The objective of this supplement is to increase the levels of nitric oxide in the blood, the famous “NO” , in order to improve congestion and increase strength and endurance.

What is citrulline?

Citrulline is what is called an amino acid nonessential . Quite simply because the human organism can manufacture it on its own from other elements. However, it is still possible to consume citrulline through food. watermelon is also known to contain citrulline naturally !

In the body, citrulline is used in particular to produce arginine which is itself used to create nitric oxide, also called NO. It is for this purpose that citrulline is consumed. Supplements that contain citrulline or arginine are also commonly called “NO booster.”
The expected result is an increase in the level of NO in the blood. However, NO has a vasodilator effect which causes greater congestion and greater blood flow. On paper, this helps bring more oxygen and nutrients to the muscles.

But the use of citrulline is controversial because it actually prevents the production of NO during exercise. These effects would therefore be rather negative and at best uninteresting.

However, the form of citrulline malate would have advantages that would make it more useful than simple citrulline. Indeed, malate has the ability to reach the mitochondria (the energy factories of cells) and to extract ammonia, a waste created during exercise. This waste can then be eliminated by citrulline. However, the accumulation of ammonia can limit performance and cause fatigue. Malate and citrulline therefore act in synergy and target another form of performance enhancement than citrulline alone.

Citrulline may not be the first supplement you should think about if you want to improve your performance. It is not better to expect better strength or better endurance from it.
