MET-Rx® Liquid L-Carnitine 3000 is one of the most versatile supplements available - perfect for all athletes. L-Carnitine helps the body convert food to energy - providing support for endurance exercise (aerobic) and during recovery from high intensity activities such as weightlifting and sprinting (anaerobic). Our formula is further enhanced with a high potency dosage of Pantothenic Acid (Vitamin B5). Once Pantothenic Acid is converted into Coenzyme A in the body, it works directly with Carnitine to convert food to Energy. Supplementing with our fast-acting L-Carnitine liquid formula helps to maximize muscle carnitine concentrations at the gym or before athletic competition.
