A form of carnitine, L-carnitine is an amino-acid-like substance found in the brain, neural tissue, muscle and heart. This naturally-occurring nutrient has been the center of much attention lately for its potential in supporting healthy weight management and muscle.
Increasing carnitine levels in the body with L-carnitine supplements may support healthy metabolism, energy levels and cholesterol and blood sugar levels already within normal range - all things that may support healthy weight management.
Bodybuilders and athletes primarily use L-carnitine to support normal endurance. However, nutritionists believe that an L-carnitine supplement taken daily may be beneficial for both active and inactive lifestyles.
