The primary use of L-carnitine is to burn fat and lose weight, but other benefits include enhanced brain function, athletic performance, and blood sugar regulation. When used to supplement a regular workout routine, L-carnitine can provide enhanced recovery and resistance from fatigue.
L-carnitine facilitates energy production by transporting fat cells to the mitochondria, where they are converted to energy. The rate of fat burn is believed to be proportional to the intake of L-carnitine. Because L-carnitine is seen as a fat burner, it has become a popular supplement to aid in weight management regimens.
