What are some risks associated with excessive protein supplementation in athletes?

Excessive protein supplementation in athletes can pose several risks, primarily through kidney strain, dehydration, and nutrient imbalances. When protein intake is significantly higher than the body's needs, the kidneys must work harder to filter out the byproducts resulting from protein metabolism, particularly urea. This increased workload may lead to kidney strain, especially in individuals with pre-existing kidney conditions.

Additionally, high protein intake can lead to dehydration. This occurs because the body requires more water to eliminate the byproducts of protein digestion, potentially leading to a greater need for hydration, and if not met, may result in dehydration.

Finally, an imbalanced diet that focuses excessively on protein may lead to nutrient imbalances, whereby an athlete may miss out on essential carbohydrates and fats that are crucial for energy and overall health. This can negatively affect performance, recovery, and general well-being. Overall, while protein is vital for muscle repair and growth, moderation and balance with other macronutrients are key.
