Helps the body convert food to energy. Promotes recovery from high intensity exercise. Supports endurance exercise. Met-Rx L-Carnitine 1500 is one of the most versatile supplement available – perfect for runners, weightlifters, athletes and anyone trying to get into better shape. 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). Supplementing with our fast-acting liquid formula helps to maximize muscle carnitine concentrations at the gym or before athletic competition. 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 – providing synergistic support.
