Is it possible that some athletes have a competitive edge because of their use of supplements and well-planned diets? Several decades of research and clinical trials have shown that athletes benefit significantly from taking supplements and eating a healthy diet regularly. Branched-chain amino acids (BCAAs), creatine, and whey protein have helped athletes breakthrough peaks and reach new levels of physical and mental well-being thanks to these and other supplements. Whey protein is a source of protein, which is essential for the growth and development of muscle mass. Because it helps muscles utilise more ATP, creatine has recently become popular as a supplement. This has led to an improvement in muscle strength.
