The Active Ingredient Is: Beta-Alanine

Beta-Alanine is a conditional, non-essential amino acid found in meat and produced by your body. It helps raise muscle carnosine stores and assists buffering lactic acid during workouts. This form is a everyday amino acid supplement used to back athletic performance and endurance.

What role does Beta-Alanine play?

Beta-Alanine helps maintain muscular endurance by delaying fatigue during high-intensity activity, a function described in sports nutrition research [which is widely studied]. Dr. Derave at KU Leuven found that beta-Alanine increases muscle carnosine and delays fatigue. Scientific evidence suggests benefits in longer training sessions when paired with regular training.
