• Citrulline malate is a connection of two active ingredients – citrulline and malic acid
• Supports ATP synthesis in the body, it is invaluable in endurance sports
• Participates in the urea cycle – increases the excretion of toxic ammonia
• Eliminates lactic acid, prevents muscle sores
• Dilates blood vessels, giving the effect of 'muscle pump'

Every athlete knows that energy is essential to perform a physical effort. ATP is a molecular entity in the intracellular transport of energy. It is created in a number of ways in the body. Studies have prven that citrulline malate increases ATP production in muscles (according to researches – by about 35%), and also takes part in the reproduction of phosphocreatine after exercises. This is especially important for athletes who do endurance sports, but not only.

Citrulline malate is a l-citrulline compound – non-protein amino acid and malic acid. L-citrulline is involved in the urea cycle (a metabolic cycle held in the liver). It helps to remove toxic ammonia from the body, emerging, among other things, from the dissolution of amino acids. Citrulline also helps to remove lactic acid, which together with ammonia is an unwanted and harmful substance being produced during exercises. This improves post-workout regeneration and comfort (less 'sores'), and also allows to exercise more efficiently.

The malic acid can be used in the Krebs cycle, which in theory may result in increased energy production.

Citrulline is a precursor to arginine and works a bit the same, because often both of these substances are present in supplements. It increases the synthesis of nitric oxide, which improves blood flow, increases its supply to muscles, pumping nutrients (amino acids, creatine). Such products are called NO-boosters or vasodilatators – they are typical pre-workouts or creatine 'matrixes'. The effect of vasodilatation is followed by the stabilization of blood pressure.

It is worth mentioning that citrulline malate before he appeared on the supplement market, he acted as a drug under the name Stimol. It is a preparation fighting a chronic fatigue. It is a product which is practically free of side effects.
