Review on 💪 L-Citrulline Pure Powder: Boost Protein Metabolism with NOW Supplements | 4-Ounce by Chris Soto

In short, citrulline is good for improving athletic performance and reducing fatigue. Citrulline is converted to arginine in the kidneys and improves blood flow better and longer than L-arginine supplementation itself. Empirical evidence suggests that citrulline supplementation improves nitric oxide, growth hormone, creatinine, plasma arginine, exercise volume, blood flow, erection , increases plasma nitrate and performance and reduces fatigue, blood pressure and muscle soreness. As such, citrulline is an excellent pre-workout or cardio supplement. Most citrulline on the internet is in the form of malate bound to malic acid. I prefer the flavor alone - or lack thereof - of L-citrulline.
