The Claim
Ingestion of 8 grams of citrulline-malate increases the number of repetitions performed to failure during upper-body resistance exercises by 13.3% in chin-ups, 20.7% in reverse chin-ups, and 9.8% in push-ups compared to placebo in trained males.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 8 grams of citrulline-malate before upper-body workouts increases the number of repetitions a trained male can perform to failure in chin-ups, reverse chin-ups, and push-ups compared to taking a placebo.
See the scientific wording
Ingestion of 8 grams of citrulline-malate significantly increases the number of repetitions performed during upper-body resistance exercises to failure in trained males, with improvements of 13.3% in chin-ups, 20.7% in reverse chin-ups, and 9.8% in push-ups compared to placebo, suggesting a direct ergogenic effect on muscular endurance in this population.
Citrulline-malate gets converted into arginine, which the body uses to make nitric oxide. Nitric oxide opens up blood vessels in the muscles, letting more oxygen and nutrients flow in while removing waste products like lactic acid faster. This keeps the muscles working longer before they tire out during repeated lifts.
What the research says
1 studyTaking 8 grams of citrulline-malate before working out helped trained men do more push-ups, chin-ups, and reverse chin-ups before getting tired, compared to when they took a placebo. The improvement was real and statistically significant.
