Citrulline - nitric oxide booster

Effect of citrulline

Citrulline is a nitric oxide booster. This means it takes part in the urea cycle in a way that indirectly contributes to arginine production stimulating nitric oxide (NO) production. Nitric oxide has a vasodilating effect on blood vessels, improving blood flow to muscles. This produces the effect of the so-called muscle pump – muscles are pumped up and optically larger. This means that during training muscle fibres are better supplied with all the components they need to work, including oxygen, which is essential for energy production. In addition, the fibres get damaged during work. Their regeneration takes time. Citrulline accelerates muscle regeneration by giving them access to a source of nutrients and oxygen.


In addition to sport, you can also find its use in other areas of everyday life and medicine. It is also a helping hand in hypertension, diabetes, heart disease, weakness or erectile dysfunction. Also, as it participates in the urea cycle it stimulates the conversion of harmful ammonia into urea which is efficiently removed in urine. This improves the condition of the body by protecting it from the accumulation of toxic compounds. As a result, the body is more nourished, purified and regenerates faster.

To increase the effect of this supplement you can add arginine to make it even more effective.
