Carnitine (L-Carnitine)

Also known as: L-Carnitine

Carnitine is an amino acid derivative that helps your body convert fat into energy and may decrease fat levels in muscle. It occurs in two forms, D and L, which are similar in structure but only L-carnitine is active in the body. In addition to helping burn fat for energy, research suggests that L-carnitine supplements may provide benefits while in training, competition and recovering from strenuous exercise. L-carnitine appears to provide benefits during cardio activities, with research showing significant increases in running speeds among athletes supplementing with L-carnitine along with decreased heart rate responses to the exercise.
