Why Carnitine for Metabolism
When it comes to metabolism, Carnitine is one of the most supporting nutrients to consider. L-Carnitine is essential for mitochondrial fatty acid transport and energy metabolism. A 2020 meta-analysis (37 RCTs) found L-carnitine supplementation significantly reduced body weight and BMI. A 2013 meta-analysis (13 RCTs) showed reduced all-cause mortality and ventricular arrhythmias in acute myocardial infarction patients. In clinical studies, carnitine supports mitochondrial energy production and fat metabolism.
How much carnitine do you need
Research points to 500–2000 mg as the effective range for carnitine. Most RCTs use 1–2 g/day of L-carnitine or ALCAR. Exercise studies use 1.5–2 g/day. Cognitive ALCAR studies use 1.5–3 g/day. Lower doses may provide some benefit, but most studies showing clear results used this range.
