Overview
L-Carnitine — a approved for deficiency states — sits in the "Approved medicine" tier of this catalog. This compound exists as an approved medicine in at least one major jurisdiction. Approval applies to specific, labeled indications and to the regulated product — not to compounded or research-grade copies.
Levocarnitine is an approved prescription medicine for primary and secondary carnitine deficiency; wellness-clinic IV use for fat loss and energy is off-label.
Mechanism of Action
Carnitine shuttles long-chain fatty acids into mitochondria for beta-oxidation — the basis of both its deficiency indication and its fat-loss marketing.
Research and Evidence
Registrational evidence supports deficiency treatment. Trials of carnitine for weight loss or athletic performance show little to no benefit.
Safety and Side Effects
Approved product safety is characterized (GI effects, fishy odor at high dose); IV wellness use lacks indication and supervision standards.
