Carnitine and energy
Carnitine plays a supporting role in energy. 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. 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.
