Citrulline

Citrulline is a non-essential amino acid that plays a crucial role in the urea cycle, where it helps to eliminate ammonia from the body. It is also involved in the production of nitric oxide, a vasodilator that promotes the relaxation of blood vessels, which can contribute to better heart health and increased blood flow. This increase in blood flow can have beneficial effects on sports performance and muscle recovery, as shown in studies on athletes who took citrulline before exercising. Although citrulline is not directly linked to an increase in strength, it can improve endurance and resistance, which is particularly useful in sports activities. Additionally, due to its effects on blood flow, citrulline is sometimes used to improve the quality of erections.

However, it is important to note that dietary supplements and interventions should be discussed with a healthcare professional to ensure their safety and efficacy.
