Supplementation plays a critical role in diets for high performers by filling nutritional gaps and enhancing physical performance. For athletes and individuals with high physical demands, supplements such as protein powders, vitamins, and minerals can provide essential nutrients that may be lacking in regular diets. These supplements aid in recovery, muscle repair, and energy replenishment. However, it is essential for high performers to consult with a healthcare professional to tailor supplementation to their specific needs and avoid excessive intake.
