Effects of Acute Citrulline Malate Supplementation on CrossFit(®) Exercise Performance: A Randomized, Double-Blind, Placebo-Controlled, Cross-Over Study
Nutrients (2024) · Crossover · n=21
The results indicated no significant difference in the number of rounds completed between the CM and placebo conditions (13.5 ± 5.2 vs. 13.8 ± 6.7 rounds, respectively; p = 0.587).
Meta-analysis of 1461 subjects showed 2.85% median improvement. Effect size 0.39 overall, with optimal effects at 5.6-6.4g/day. Most effective for 1-4 minute high-intensity efforts. Side effect risk primarily reflects paresthesia (tingling), which is common but harmless.
Meta-analysis showed small effect (SMD=0.196) with ~3 additional reps. Several individual studies showed mixed results including null findings. Effect appears inconsistent across different exercise modalities.
