L-Carnitine is the naturally occurring amino acid derivative essential for shuttling long-chain fatty acids into mitochondria for beta-oxidation and ATP production. The L-form is the only biologically active isomer (D-carnitine is inactive and potentially inhibitory). First identified in 1905 and synthesized in 1950s, it is widely used in metabolic, sports nutrition, and cardiovascular research. This research-grade crystalline powder is produced under strict quality controls and provided with full analytical documentation, ideal for fat metabolism, endurance, and mitochondrial function studies.
