L-Carnitine, an amino acid, supports energy production in cells by transporting fatty acids into the mitochondrion. In this role, L-carnitine supports the body to efficiently metabolise fat. Fumarate, or fumaric acid, is a naturally occurring compound in the body where it serves as an intermediate in the Krebs cycle, a key energy-producing process. Doctor’s Best L-Carnitine Fumarate is derived from pharmaceutical grade L-carnitine manufactured by a patented, FDA-approved process.
L-carnitine’s primary function is to transfer fatty acids across the inner mitochondrial membrane. Fatty acid molecules are activated to coenzyme A (CoA) esters in the cytoplasm of the cell, and then esterified to L-carnitine. The combination of a fatty acid molecule and L-carnitine is called “acyl-carnitine.” Much of the body L-carnitine content is stored in the form of acyl-carnitine.
Doctor’s Best creates vitamins and supplements using science-based techniques that combine natural ingredients using thoroughly researched and tested methods. Doctor’s Best is committed to transparency and education, and uses only certified cGMP facilities to ensure the highest quality standards are met.
