Acetyl L-Carnitine is a stabilized and more absorbable form of the amino acid L-Carnitine. It plays an important role in protecting and supporting brain and muscle function. ALC facilitates the metabolsim of fatty acids for energy generation which improves exercise capacity and fat loss. ALC has profound effects on endurance and exercise performance by reducing the respiratory exchange ratio and reducing lactic acid acccumulation in muscles extending exercise capacity before fatigue.
