Product overview

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.

  • Supports healthy fat burning for energy.
  • Maintains a healthy heart and cardiovascular system.
  • For anyone who regularly trains, this combination supports endurance during workouts and may support recovery from high-intensity exercise.
How does it work?

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.
