There is some evidence to suggest that high-protein diets and excessive protein supplement use can increase the risk of kidney stones in some individuals. This is because a high-protein diet can lead to the production of excess nitrogen waste products, which can strain the kidneys and increase the concentration of substances in the urine that can lead to kidney stone formation.
However, for most healthy individuals, moderate protein intake from dietary sources or supplements is not associated with increased risk of kidney stones. Additionally, individuals with existing kidney problems or those who are prone to kidney stones may need to limit their protein intake, and should consult with a healthcare professional before using protein supplements.
It's important to keep in mind that a balanced diet, adequate hydration, and regular physical activity are important factors in maintaining kidney health and reducing the risk of kidney stones.
