L-Carnitine is essential for transporting long-chain fats into the cell (mitochondria). L-Carnitine taps into the fat supply and may provide support to burn it as fuel, resulting in increased energy. Without L-Carnitine, these fats cannot be burned for energy and are instead shunted to stored body fat. L Carnitine has also been shown to readily cross the blood-brain barrier and may help to maintain healthy brain function and memory associated with ageing.
L-Carnitine has been widely used by athletes and bodybuilders.
