Evidence has shown that L-carnitine can promote mitochondrial biogenesis by upregulating peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1), a master regulator of mitochondrial biogenesis [14] and that L-carnitine promotes mitochondrial protein acetylation, a chemical modification that improves mitochondrial function and protects against stressors
