L-carnitine is essential for the transport of fatty acids into the mitochondria
(energy powerhouse of the cell) where they can be used to make energy to be
used by the cells.*
- L-carnitine has been shown to help support healthy cardiovascular function,especially the efficiency of heart muscle function which uses fat as its majorsource of energy.
- L-carnitine helps provide energy for exercising muscle, supporting exerciseperformance.
- Studies show L-carnitine helps support normal, healthy blood triglyceride levels.
L-carnitine is a non-essential amino acid that can be synthesized in the body from the amino
acids methionine and lysine. Insufficient amounts may be produced in infants, in adolescents
and in adults under certain physiological conditions. Vegetarians could also be at risk for
carnitine deficiency, as carnitine is found in higher concentrations in animal foods such as
beef, poulty and pork. The amino acids that are required for the body to make carnitine
(methionine and lysine) are also low in a vegetarian diet. The highest concentrations of L-
carnitine are typically found in skeletal and cardiac muscle tissue. This tissue is incapable of
synthesizing L-carnitine, so they depend upon dietary and supplemental sources as well as
the body’s own ability to manufacture it. Studies show that exercising (skeletal) muscle and
heart muscle require large amounts of L-carnitine. The main function of L-carnitine is to
help create energy. Cardiac (heart) and skeletal muscle have a significant energy
requirement, hence the importance of L-carnitine for these tissues.
