| L-Carnitine Supplementation Exercise Recovery Meta-Analysis | No trial differences were found for I-FABP (interaction effect, p = 0.076), L: 13 CM ( p = 0.559), the neutrophil/lymphocyte ratio ( p = 0.171), serum cortisol ( p = 0.982), serum myoglobin ( p = 0.942), or serum creatine kinase ( p = 0.694). | 4 | Nieman DC (2025) | Betaine Supplementation Improves 60 km Cycling Time Trial Performance and One-Carbon Metabolism in Cyclists During Recovery. |
| L-Carnitine Supplementation Exercise Recovery Meta-Analysis | Conclusions Betaine supplementation modestly improved 60 km cycling performance but had no effect on gut permeability. | 4 | Nieman DC (2025) | Betaine Supplementation Improves 60 km Cycling Time Trial Performance and One-Carbon Metabolism in Cyclists During Recovery. |
| L-Carnitine Supplementation Exercise Recovery Meta-Analysis | Background/objectives This study examined the effects of 2 weeks of betaine versus placebo supplementation (3 g/d) on 60 km cycling performance, gut permeability, and shifts in plasma metabolites. | 4 | Nieman DC (2025) | Betaine Supplementation Improves 60 km Cycling Time Trial Performance and One-Carbon Metabolism in Cyclists During Recovery. |
| L-Carnitine Supplementation Exercise Recovery Meta-Analysis | A randomized, placebo-controlled, double-blind, crossover design was used with two 2-week supplementation periods and a 2-week washout period. | 4 | Nieman DC (2025) | Betaine Supplementation Improves 60 km Cycling Time Trial Performance and One-Carbon Metabolism in Cyclists During Recovery. |
| L-Carnitine Supplementation Exercise Recovery Meta-Analysis | This process is associated with the increase in the production of free radicals from mitochondrial activity and the postexercise increase in muscle inflammation []. | 4 | Caballero-García Alberto (2023) | Effects of L-Carnitine Intake on Exercise-Induced Muscle Damage and Oxidative Stress: A Narrative Scoping Review |
| L-Carnitine Supplementation Exercise Recovery Meta-Analysis | Likewise, EIMD is associated with an increase in muscle proteins in blood such as creatine kinase (CK), lactate dehydrogenase (LDH) and myoglobin (Mb). | 4 | Caballero-García Alberto (2023) | Effects of L-Carnitine Intake on Exercise-Induced Muscle Damage and Oxidative Stress: A Narrative Scoping Review |
| L-Carnitine Supplementation Exercise Recovery Meta-Analysis | The complex carnitine-acyl-CoA is recognized by mitochondrial inner membrane-associated transporters, delivering long-chain fatty acids into the mitochondrial matrix, where they undergo β-oxidation []. | 4 | Caballero-García Alberto (2023) | Effects of L-Carnitine Intake on Exercise-Induced Muscle Damage and Oxidative Stress: A Narrative Scoping Review |
