See the technical phrasing

On a gram-per-gram basis, L-citrulline is more effective than L-arginine at increasing plasma L-arginine concentrations, likely due to its avoidance of first-pass metabolism in the liver and intestines, and 3 g of L-citrulline taken twice daily produces a greater plasma arginine area under the curve (AUC) than equivalent doses of L-arginine.
