L-Citrulline DL-malate is widely used as a dietary supplement, particularly in the fitness and health industries, due to its ability to enhance athletic performance and reduce fatigue. It works by increasing nitric oxide production in the body, which improves blood flow and oxygen delivery to muscles during exercise. This makes it a popular choice among athletes and bodybuilders for boosting endurance and recovery. Additionally, it is often included in pre-workout formulas to support energy levels and reduce muscle soreness post-exercise. Beyond sports, it is also used to support cardiovascular health and improve symptoms of conditions like erectile dysfunction by promoting better circulation. Its combination with malate further aids in energy production by supporting the Krebs cycle, making it effective for combating fatigue and enhancing overall physical performance.
