Citrulline malate pairs the amino acid L-citrulline with malic acid. This combination aims to support energy production during exercise while slowing the buildup of metabolites tied to fatigue.
Athletes use it to help maintain blood flow and endurance through a workout, then recover faster afterward. Most people take it in the 30 to 60 minute window before training. Taking it on an empty stomach speeds up absorption.
A few people notice mild stomach upset. Because citrulline malate can lower blood pressure, anyone on blood-pressure medication should check with a doctor first.
