What is the recommended dosage for L-Carnitine?

General: 500-2,000 mg/day; Weight Management: 2,000-3,000 mg/day L-carnitine L-tartrate; Exercise Performance: 2,000 mg/day

What are the side effects of L-Carnitine?

Potential side effects include: Fishy body odor, Nausea, Diarrhea, Abdominal cramps.

What is L-carnitine and how may it support weight management?

L-carnitine is an amino acid derivative that plays a role in transporting fatty acids into mitochondria for energy production. A 2020 meta-analysis of 37 RCTs found that L-carnitine supplementation was associated with modest reductions in body weight. Results varied based on dosage and study population.

What dosage of L-carnitine has been studied for weight management?

Clinical trials have used 1–3 grams of L-carnitine per day, with 2 grams being the most common dose. Both L-carnitine L-tartrate and acetyl-L-carnitine forms have been studied. Trial durations typically ranged from 8 to 24 weeks.

What are the potential side effects of L-carnitine supplements?

Common side effects include nausea, abdominal cramps, vomiting, and diarrhea. High doses (above 3 grams daily) may produce a fishy body odor. Some research suggests that gut bacteria can convert L-carnitine to trimethylamine N-oxide (TMAO), which has been associated with cardiovascular risk.

About

An essential cofactor for transporting long-chain fatty acids into mitochondria for energy production. Meta-analyses of 37 RCTs demonstrate that L-carnitine supplementation may support healthy body weight and body composition, particularly when combined with physical activity.

How It Works

Essential cofactor for carnitine palmitoyltransferase (CPT) enzyme system, which transports long-chain fatty acids across the mitochondrial membrane for beta-oxidation. Without adequate carnitine, fatty acids cannot enter mitochondria for energy production. Also supports pyruvate dehydrogenase activity, improving overall substrate utilization.
