Supplements can impact an athlete’s performance by providing essential nutrients that may be lacking in their diet. Certain supplements, like protein powder, enhance muscle recovery and growth, while others, such as creatine, can improve strength and power output during high-intensity exercise. Additionally, branched-chain amino acids may help reduce muscle soreness and fatigue. However, the efficacy and necessity of supplements can vary based on individual dietary needs and exercise goals. Athletes should consult a healthcare professional before incorporating supplements, ensuring they complement a balanced diet.
