Published in Nutrients
Methodology
Meta-analysis of randomized trials of L-carnitine supplementation reporting post-exercise blood lactate and performance markers.
Key Findings
Pooled effects on post-exercise blood lactate were small and inconsistent, with no reliable performance benefit in trained participants.
Conclusions
Evidence does not support L-carnitine as an effective lactate-clearance aid.
Limitations
Dose and loading duration varied widely; several trials were small and unblinded.
Supplements Studied
Pooled effects on post-exercise blood lactate were small and inconsistent
Outcomes Measured
Pooled effects on post-exercise blood lactate were small and inconsistent, with no reliable performance benefit in trained participants
