The Effect of L-Carnitine Supplementation on Exercise-Induced Muscle Damage: A Systematic Review and Meta-Analysis of Randomized Clinical Trials
Fielding R, Riede L
Published in Journal of the American College of Nutrition
Methodology
Systematic review and meta-analysis of randomized trials of L-carnitine on markers of exercise-induced muscle damage and recovery.
Key Findings
L-carnitine reduced post-exercise creatine kinase and myoglobin, consistent with improved mitochondrial fatty acid handling and recovery.
Conclusions
L-carnitine modestly supports oxidative metabolism and recovery from strenuous exercise.
Limitations
Heterogeneous doses and forms; small trials.
Supplements Studied
L-carnitine reduced post-exercise creatine kinase and myoglobin, consistent with improved mitochondrial fatty acid handling
Outcomes Measured
L-carnitine reduced post-exercise creatine kinase and myoglobin, consistent with improved mitochondrial fatty acid handling
L-carnitine supplementation attenuated markers of exercise-induced muscle damage
