L-carnitine is a non-essential amino acid that is made by the kidney and the liver and is derived from the amino acids methionine and lysine. Carnitine plays an important role in transporting long-chained fatty acid across the mitochondrial membranes in cell in order to produce energy. Recent research has determined that carnitine may play a role in lowering cholesterol and triglyceride levels, as well as improving cardiac performance.
==Special Precautions of L-Carnitine==
* Heart disease risk : L-carnitine, which is found in red meat and is also popular as a dietary supplement, may play a role in the development of heart disease.
