A combination of the amino acid L-citrulline with aspartic acid, sold as a salt form. The body converts citrulline into arginine, a building block for nitric oxide.

Why it’s used

Taken by some to support blood flow and exercise performance, or to reduce feelings of fatigue during exertion.

What the evidence says

Most exercise research on citrulline uses the malate salt rather than the aspartate salt on this label, and even that evidence is mixed; the aspartate-specific human literature is too small and inconsistent to draw a conclusion about oral use.

Context

Where citrulline compounds have been studied for exercise, protocols vary widely in dose and timing, and results differ by the specific salt form and outcome measured.

Insufficient dataToo little has been studied to say either way.
