Beta-Alanine boosts muscle endurance and strength:
Beta-Alanine increases intra-muscular Carnosine concentrations, thereby improving working capacity and performance by up to 20%. Scientific research has demonstrated that Beta-Alanine taken with creatine monohydrate produced additional synergistic effects, including fat free mass gain, increased strength and increased body fat reductions. Beta alanine will give you a more effective workout and is the great addition to your supplement regimen.
Much of Beta-Alanine beneficial effects come through increasing the synthesis of carnosine, a powerful intracellular buffer. Carnosine is found in both type 1 and type 2 muscle fibers, though in significantly higher concentrations in type 2 fibers (the fibers we use in high intensity strength workouts and which are most responsive to growth). To function effectively, muscle cells rely on buffers like carnosine to avoid becoming acidic (low pH) during exercise. In order for muscles to remain strong and maintain powerful contractions, they need to be in an optimal pH range. If the pH drops below that optimal level your muscles will have significantly less strength and will fatigue more quickly.
You know the pH is dropping when you feel that familiar lactic acid burn in your muscles. Lactic acid builds up largely as a result of an increase in hydrogen ions which build up when you exercise. Beta-Alanine helps to increase carnosine which acts to buffer lactic acid and return pH level within muscle cells back to optimum levels.
