• How does beta-alanine work?

  • Beta-alanine works primarily by enhancing muscular endurance and performance, particularly in high-intensity exercises. It does so by increasing the concentration of carnosine in muscles. Carnosine is a dipeptide that serves to buffer acid in muscles, which improves endurance by allowing muscles to sustain high-intensity activity for longer periods before fatigue sets in. This buffering effect helps delay the onset of muscle fatigue and enhances overall performance during activities like weightlifting or sprinting, which typically last from 60 to 240 seconds. For a detailed explanation, it would be helpful to refer to episodes of the Huberman Lab podcast where Andrew Huberman discusses this topic.
