Citrulline er en forbindelse som støtter blodstrøm og muskelutholdenhet. Den hjelper kroppen med å produsere nitrogenoksid, som avslapper og utvider blodårene. Citrulline finnes naturlig i matvarer som vannmelon, agurk og gresskar, og er populært blant idrettsutøvere for sin evne til å forbedre treningsprestasjon, redusere tretthet og akselerere restitusjon. Den spiller en nøkkelrolle i sunn sirkulasjon og effektiv fysisk ytelse.
Testing for citrulline levels could benefit athletes and individuals engaged in regular, intense physical activity, as citrulline is known to enhance blood flow and muscle endurance. It may also be useful for individuals with cardiovascular issues, erectile dysfunction, or high blood pressure. Additionally, those with certain metabolic disorders that could impact amino acid processing might find testing helpful to ensure optimal levels for health and performance.
Citrulline is found in watermelon, which is one of the richest natural sources. Other sources include cucumbers, melons, pumpkins, and gourds. While not as concentrated as in watermelon, citrulline can also be found in meats and nuts, contributing to its dietary intake.
Citrulline supplementation is beneficial for improving blood flow and enhancing exercise performance, particularly in endurance sports. It aids in reducing fatigue and improving recovery after workouts. Citrulline can also support cardiovascular health by improving blood vessel dilation and circulation. Additionally, it might help with erectile dysfunction by improving blood flow.
