L-citrulline 750mg -180 capsules

L-citrulline: increases exercise intensity, for strength, pump and endurance.

Citrulline is a non-essential amino acid, which is an intermediate in the urea cycle and works together with arginine and ornithine, to help the body to get rid of ammoniac, a by-product of the protein metabolism.
L-citrulline is a particularly popular product to support the training, the regeneration, the liver function and the energy generation. This natural amino acid is important for every athlete, because it helps the body to break down ammoniac, a by-product of intensive training. Citrulline promotes an increased nitric oxide formation and its circulation stimulating effect improves the muscle strength and endurance. As a precursor of arginine, citrulline can be of importance for the endogenous arginine level.
Citrulline is also important for the maintenance of a healthy immune system.


  • for a better pump
  • can support the liver
  • removes high-performance sport-related metabolic end products
  • supports a fast regeneration after the training
  • promotes muscle strength and endurance
  • pure substance


Tip: Combine citrulline with creatine, because citrulline increases the creatine resynthesis. It helps to restore high creatine levels in the musculature as well as maximise regeneration and performance.

Scientist of the University Hospital Hamburg-Eppendorf, Germany, were able to prove that the consumption of citrulline increases the plasma concentration of arginine and the NO formation depending on the dosage. Citrulline increased the arginine plasma level even more effectively than arginine itself. Unlike arginine, citrulline isn´t broken down by the intestinal arginase.

Persons, who eat watermelon before exercising, have a lower risk of suffering from sore muscles after the training, which was found out by Spanish scientists. It´s assumed that the L-citrulline, which occurs naturally in the watermelon, is responsible for this effect. Trial participants, who drank a watermelon beverage one hour before exercising, were able to reduce sore muscles.
