Ask a question


Carnitine is a peptide or amino acid that an organism synthesizes in the kidneys and the liver. Carnitine is involved in the transport of fatty acids to the cells and is indispensable for the proper functioning of muscles. The principal dietary sources of carnitine are red meat, avocado, and dairy products. It is much better absorbed when consumed as food, rather than in the form of supplements. Carnitine is also available as a prescribed medication, but remains subject to caution as it may provoke disorders, especially in the liver.
