Dietary supplements can impact athletic performance by enhancing nutrient intake, promoting recovery, and improving overall health. Certain supplements, like protein powders, can aid in muscle repair and growth, particularly after intense exercise. Others, such as creatine or beta-alanine, may enhance performance by increasing endurance or strength during high-intensity workouts. However, it is important for athletes to consult healthcare professionals before taking supplements, as not all substances are regulated or necessary for everyone, and misuse can lead to negative health effects.
