L-Carnitine plays a role in increasing your body's metabolism. It achieves this by improving mitochondrial function (membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions) and increasing cellular energy (energy from fat). L-Carnitine is an important amino acid, many sports athletes use it to help them burn fat, reduce muscle fatigue and speed up workout recovery.
