Ingredient and preparation

L-citrulline is an amino acid. It is distinct from citrulline malate, a combination label that may not match studies of citrulline alone.

Sources: National Library of Medicine, PubMed

Evidence and limits

A 2022 systematic review found no pooled positive effect on its included aerobic-performance outcomes. That does not answer every exercise question or establish a benefit for other outcomes.

Sources: National Library of Medicine, PubMed

Safety and a useful record

The review is not a safety or dosing instruction. Review medicines and health conditions with a suitable professional before changing use.

Sources: National Library of Medicine, PubMed, National Center for Complementary and Integrative Health

Record whether the label is L-citrulline alone or a mixed product, plus the outcome and training context.
