Citrulline belongs to proteinogenic amino acids. Watermelons are the richest natural source of citrulline and its great amounts are also found in cucumber and pumpkins. In the body, the amino acid takes part in the urea cycle, a cycle of metabolic reactions leading to the formation of urea from ammonia, aspartate and carbon dioxide. Citrulline is also involved in the synthesis pathway of nitric oxide (which overlaps with the urea cycle) that is the main mechanism for blood vessel function.
Huge muscle pump
Along with arginine, citrulline is one of the most popular supplements boosting peripheral blood flow, resulting in the so-called muscle pump. Even though citrulline exerts its effects by increasing arginine levels in the body, consequently enhancing nitric oxide production, citrulline supplementation has been shown to be more effective in boosting its synthesis than arginine alone.
Because of vasodilatory effects, the amino acid improves the delivery of nutrients to hard working muscles and therefore their efficiency. Increased blood circulation also helps maintain an optimum biochemical environment in myocytes. This enables you to train more effectively which, combined with a motivating “pumped feeling”, may significantly improve training performance.
Due to the ability to widen blood vessel lumen, citrulline has been demonstrated to be capable of reducing hypertension. There are studies which indicate that the amino acid may be a safe way to regulate blood pressure.
Enhanced sexual function
Since citrulline has vasodilatory properties, it can also make it easier to achieve and maintain an erection. By stimulating blood supply to the penis, citrulline supplementation supports maximum sexual performance in men.
Increased energy levels
Citrulline shows the ability to promote physical performance not only due to its vasodilatory properties. It may also encourage energy metabolism. Since citrulline boosts adenosine triphosphate production, it is all the more important in the context of pre-workout supplementation. By increasing energy levels, it helps you incorporate varied training stimuli and thus accelerate your progress.
Enhanced muscle anabolism
Citrulline supplementation may also speed up muscle tissue development. It has been indicated to have a beneficial impact on the activation of the mTOR pathway which stimulates anabolic processes. Even though this mechanism of action of citrulline has not been fully recognised yet, it is believed that the amino acid is not so much an activator of the mTOR pathway but it rather regulates its suppression.
Increased growth hormone levels
Citrulline may also stimulate anabolic processes by promoting the release of growth hormone, but only after a workout. This is the next reason why physically active persons should take citrulline before exercise to enhance training effectiveness.
To sum up, MZ-Store Citrulline is a pre-workout supplement improving training quality in multiple ways. It does not only stimulate blood supply to peripheral tissues but also promotes muscle anabolism and energy metabolism. In addition, it can be used to increase your ability to achieve and maintain an erection.
