L-carnitine has a major role in fat metabolism and energy production as it carries long-chain fatty acids and transports them to mitochondria (the powerhouse of cells), where these acids get oxidized and produce energy

Oxidative-stress-mediated arterial dysfunction in patients with peripheral arterial disease

Studies suggest that L-Carnitine can contribute to endurance and decrease fatigue

KD lowers insulin, causing a decrease in IGF-1, which consequently leads to an increase in IGFBP-3 (191)
