Studies & key findings
- L-Carnitine is NOT a peptide — it's an amino-acid derivative (from lysine and methionine) essential for shuttling long-chain fatty acids into mitochondria for energy production. It is FDA-approved (Carnitor) for carnitine deficiency.
- It has the strongest peer-reviewed evidence base of the compounds in this library: a 2020 meta-analysis (37 RCTs) found modest weight/fat loss, and a 2013 Mayo Clinic meta-analysis linked it to reduced mortality and arrhythmias after myocardial infarction.
