MET-Rx Liquid L-Carnitine 1500 is one of the most versatile supplements available – perfect for all athletes. 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 liquid formula helps to maximize muscle carnitine concentrations at the gym or before athletic competition.
