Beta-alanine does not increase muscle mass or burn fat; rather, it buffers against acid accumulation, allowing the individual to work out harder and for longer periods of time. The end consequence is, of course, more muscle building and fat reduction. Beta-alanine also has been shown to enhance performance of athletes who take it. Short-term use of high doses of beta-alanine may lead to weight loss, but long-term use could have the opposite effect. More research is needed on the effects of beta-alanine over time and at different dosage levels.
