Beta-Alanine is an amino acid that is naturally made by the body but also found in animal products (especially chicken breast meat and fish). Beta-Alanine is important in the production of a protein called Carnosine which can buffer (“soak up”) acid byproducts produced during high intensity exercise. You may know this as lactic Acid
During high intensity exercise, energy production results in an increase in hydrogen ions that increase the acidity in the muscle (decrease muscle pH) which can cause fatigue and impair performance. Carnosine acts by “soaking” up these hydrogen ions to regulate muscle acidity (pH) and increase fatigue resistance and potentially increase training capacity and performance.
