Shuttles long-chain fatty acids across the mitochondrial membrane, enabling their oxidation for energy production. This supports fat metabolism and cellular energy.
Used as a supplement for energy, exercise recovery, and fat metabolism; medically for genuine carnitine deficiency.
Generally well tolerated, may modestly support exercise recovery and fat metabolism, and is essential for treating true carnitine deficiency.
Weight-loss benefits in healthy people are small and inconsistent; high doses can cause nausea, diarrhea, a fishy body odor, and possibly raise TMAO.
Users report improved energy and recovery, though many acknowledge fat-loss effects are subtle.
Legal as an oral supplement: sold widely as a dietary supplement; an injectable prescription form (Carnitor) is FDA-approved only for carnitine deficiency.
