The Performance Enhancing Molecule Known as Beta-Alanine

image_pdfimage_print

Beta-alanine is a modified version of the amino acid alanine. Once ingested, it turns into the molecule carnosine, which acts as a potent acid buffer in the body.

Carnosine is stored in body cells and released in response to drops in pH. Increasing body stores of carnosine can protect against diet-induced drops in pH (which might occur from ketone production in ketosis, for example) and protect from exercise-induced lactic acid production.

By buffering lactic acid, beta-alanine has been shown to enhance performance in muscular endurance.
