Performance-enhancing supplementation can play a controversial role in sports by potentially improving strength, endurance, and recovery. Substances like steroids, stimulants, and other ergogenic aids can provide an athletic advantage but often come with serious health risks and ethical implications. Many sports organizations regulate or ban specific supplements to maintain fairness, as their misuse can undermine the spirit of competition. Athletes are encouraged to focus on natural nutrition and training methods to enhance performance sustainably. Ultimately, the decision to use supplements should involve careful consideration of health consequences and adherence to sporting regulations.
