L-Carnitine ： Fat Oxidation Enhancement

B

Meta-analysis of 37 RCTs (n=2,292) found significant reductions in body weight (1.21 kg), BMI (0.47), and fat mass (2.17 kg). Effects were more pronounced with doses of 2,000 mg/day or greater and when combined with exercise. L-carnitine is essential for mitochondrial fatty acid transport.
