Why Do Athletes Use It?*

Some athletes say that branched-chain amino acids helps improve strength-training and endurance results.

What Do the Advocates Say?*

A good deal of research has been done on branched-chain amino acids (BCAAs) in athletes, but results are quite mixed. BCAAs do not seem to enhance training benefits or exercise performance in most situations. Some athletes, however, may experience increased mental clarity during exercise or may be less susceptible to infections caused by the stress of exercise. Performance under extreme conditions, such as high altitude or heat, may also be improved with BCAAs.

*Athletes and fitness advocates may claim benefits for this supplement based on their personal or professional experience. These are individual opinions and testimonials that may or may not be supported by controlled clinical studies or published scientific articles.
