L-Carnitine is a naturally occurring amino-acid derivative essential for fatty-acid transport into mitochondria, widely used in biochemical and metabolic research. It is supplied as a high-purity lyophilized powder in sealed vials for laboratory use. L-Carnitine is investigated in research on fatty-acid oxidation, energy metabolism and mitochondrial function, and is commonly applied in cell-based and nutritional studies. The lyophilized form provides high stability and easy reconstitution for consistent experimental dosing.. All lots pass strict quality verification and lot-specific certificates can be provided on request.
