What impact does a high dose of L-citrulline malate have on exercise performance and recovery, particularly in terms of the potential benefits of increased blood flow, reduced muscle soreness, and enhanced aerobic capacity? With some studies suggesting that L-citrulline malate supplementation may delay the onset of fatigue and improve high-intensity exercise performance, its worth exploring how this might benefit endurance athletes such as cyclists and distance runners. Furthermore, what role might L-citrulline malate play in enhancing the efficiency of energy production during exercise, and what are the potential benefits of combining L-citrulline malate with other ergogenic aids, such as beta-alanine or creatine? On the flip side, what potential drawbacks or side effects should athletes be aware of when considering L-citrulline malate supplementation, and how might individual differences in genetics, training status, or dietary habits influence the effectiveness of this supplement?
