About L-Carnitine and Fumarate

L-Carnitine is a vitamin-like nutrient that is synthesised in the body, using the amino acids lysine and methionine as precursors. Because the body produces L-Carnitine on its own, it cannot be classified as a vitamin, even though it has functions similar to B vitamins. Fumarate is also a natural compound found in the body.

Fumarate serves as an intermediate in the Krebs cycle, a key cellular energy-producing process.

L-Carnitine and Fumarate both play important roles in energy metabolism.

Supports the body in normal fat burning for energy.

L-Carnitine promotes energy production in cells by transporting fatty acids into the mitochondrion. The mitochondrion is the cells energy-generating furnace. Called an “organelle,” the mitochondrion is a self-contained structure inside the cell. Like all cellular structures, the mitochondrion is surrounded by a membrane. This membrane is an impenetrable barrier, passage across the membrane requires L-Carnitine as a transporters.

L-Carnitine and short chain acyl-carnitine esters may help support healthy mitochondrion.
