Dietary supplements can enhance workout performance by providing nutrients that may be lacking in an individual's diet, thereby optimizing physical output. For example, certain supplements like creatine and BCAAs have been shown to improve strength, endurance, and muscle recovery. Others, such as protein powders, can support muscle growth and repair post-workout. Additionally, vitamins and minerals play essential roles in energy production and overall metabolic function. While supplements can be beneficial, they should not replace a balanced diet; instead, they should complement a well-rounded nutritional plan to maximize workout effectiveness.
