L-Citrulline Malate pairs the amino acid citrulline with malic acid. Malate takes part in the Krebs cycle, the body’s energy machinery, which helps dull the feeling of fatigue during exercise. Athletes and active people often choose this form over plain citrulline because it supports energy output and blood flow. Some users find it gentler on the stomach.
Most people take it 30 to 60 minutes before training to lift performance and speed recovery afterward. An empty stomach works well for many. Others handle it better with a light snack.
Side effects are usually mild but can include stomach upset, especially at larger doses. Anyone on blood pressure medication should check with a doctor first since L-Citrulline can amplify the pressure-lowering effect. Safety information for pregnant or nursing women is lacking.
