Carnitine plays a critical role in energy production. It transports long-chain fatty acids into the mitochondria so they can be oxidized ("burned") to produce energy. It also transports the toxic compounds generated out of this cellular organelle to prevent their accumulation. Given these key functions, carnitine is concentrated in tissues like skeletal and cardiac muscle that utilize fatty acids as a dietary fuel.
Carnitine / Acetyl L-Carnitine: What is it?
Carnitine, derived from an amino acid, is found in nearly all cells of the body. Its name is derived from the Latincarnus or flesh, as the compound was isolated from meat. Carnitine's benefits are well established and is absolutely essential for normal heart function. Over time, the decline of carnitine may play a role in the weakening of the heart's muscle.
