Abstract

Currently, the supplement market has gained a large dimension, promising products that can increase performance and muscle hypertrophy. This review aimed to address which are the main single-component products suggested and how effective they are without intending to cover the entire subject. For that, we use our previous work and what is in the field. As main results, we observed that some supplements, such as caffeine and creatine, have a robust body of evidence regarding their effectiveness. Other products, such as beta alanine, BCAA, sodium bicarbonate, arginine, present several favorable results for their use, however, with some studies not proving this effectiveness. Thus, future well-controlled studies are suggested to clarify some controversies observed.
