                                Studies have repeatedly shown that supplementing with L-citrulline raises plasma L-arginine levels more effectively than taking L-arginine directly. This superior bioavailability is the primary reason why many individuals now opt to take citrulline instead of arginine for promoting nitric oxide production and enhancing athletic performance.
