AllNutrition Beta-Alanine Powder is an excellent supplement to use during intense workouts. Beta-alanine is an organic chemical compound classified as an ergogenic agent. It is a laboratory-modified isomer of a naturally occurring amino acid, alanine. After consumption, it is used in the production of carnosine, which acts as an acid regulator in the body. Carnosine stored in muscle cells is released in response to a decrease in pH, thereby regulating their acidity. The more carnosine in the muscles, the longer your workout will last. Increase the duration and intensity of your workout. Reduces muscle fatigue. Increases carnosine levels.
