Supplements for Sports Performance

What the Research Shows

Scientific research identifies a small number of supplements with clear benefits for athletic performance. Creatine monohydrate and caffeine possess strong evidence for improving strength, power output, and endurance. Beta-alanine is supported by moderate evidence for buffering lactic acid during high-intensity exercise, while Rhodiola is considered to have moderate evidence for reducing perceived exertion and fatigue. However, many popular supplements lack rigorous backing. Evidence for most branched-chain amino acids (BCAAs) is weak or conflicting, as their benefits often depend on overall protein intake. For many other performance boosters, evidence remains insufficient due to small sample sizes or poor study designs. Because individual responses vary and long-term data are often missing, the effectiveness of these substances can be inconsistent across different sports and fitness levels.
