Description

Amino acid derivative studied for its role in shuttling fatty acids into mitochondria for beta-oxidation (energy production), with research interest in exercise performance, fat metabolism, and recovery. An FDA-approved injectable form (levocarnitine) exists specifically for diagnosed primary/secondary carnitine deficiency, particularly in dialysis patients; general “energy/metabolism” injectable use outside that diagnosis is off-label, with limited evidence that supplementation meaningfully changes fat metabolism in people who are not deficient.
