L-Carnitine is a naturally occurring amino acid which plays a vital role in the metabolism of fat. It functions as a transporter of fatty acids into the mitochondria, the metabolic furnace of the cell. Carnitine boosts energy by stimulating the body’s burning of tryglycerides as fuel, and sparing the supply of glycogen stored in the liver for heavier exertion. During exercise, the body will burn fat at a rate of 75-80% of maximum exertion, thus less glycogen from carbohydrates is burned. L-carnitine allows the body to burn more fat, save more glycogen, and ultimately boost stamina and endurance. By providing more fat to the muscles, carnitine makes accessible an otherwise unavailable energy source. Signs of low carnitene include fatigue, weight gain, high cholesterol and triglycerides, and weakened heart function. Supplementation can aid in reversing these symptoms, creating a more healthy and proper functioning body.
It is also gaining a reputation as a nootropic (brain nutrient) which can reduce age related mental decline. It can specifically increase alertness and attention span, improve learning and memory, and boost hand-eye coordination.
