L-carnitine

L-Carnitine is the naturally occurring amino acid derivative essential for shuttling long-chain fatty acids into mitochondria for beta-oxidation and ATP production, as described in scientific literature ([ods.od.nih.gov](https://ods.od.nih.gov/factsheets/Carnitine-HealthProfessional/)). The L-form is the only biologically active isomer — D-carnitine is inactive and potentially inhibitory. First identified in 1905 and synthesized in the 1950s, it is widely studied in metabolic, mitochondrial, and cardiovascular research contexts. This research-grade crystalline powder is produced under strict quality controls and includes full analytical documentation, making it suitable for in vitro and laboratory studies of fatty acid metabolism and mitochondrial function.
