Explore whether creatine supplementation Can Creatine Cause Kidney Stones?, based on a case report and scientific evidence. Learn about the effects of creatine monohydrate on renal function and kidney stone recurrence.
Creatine monohydrate supplementation (CMS) is widely used by athletes to enhance performance, particularly in high-intensity, short-duration exercises. While decades of research have shown that creatine is generally safe for healthy individuals, concerns have been raised about its potential effects on kidney function and the risk of kidney stones. This article examines whether creatine can cause kidney stones, based on a case report involving an athlete with a history of kidney stones.
Do Bodybuilders Get Kidney Stones?
Bodybuilders and athletes often consume dietary supplements, including creatine, to improve performance and muscle mass. However, the relationship between creatine supplementation and kidney stones remains unclear. In the case of a 28-year-old bodybuilder with a history of kidney stones, creatine monohydrate supplementation for two months did not lead to the recurrence of kidney stones.
The athlete, who had previously passed a small kidney stone, underwent extracorporeal shock wave lithotripsy (ESWL) to break down an 11 mm kidney stone. After the procedure, he started taking creatine monohydrate (5 grams/day) for two months. A follow-up ultrasound 14 months later showed no new kidney stone formation.
This case suggests that creatine supplementation may not increase the risk of kidney stones in athletes, even those with a history of the condition. However, more research is needed to confirm these findings.
What Supplements Cause Kidney Stones?
While creatine does not appear to cause kidney stones, other supplements and dietary factors may contribute to their formation. High doses of vitamin C, calcium, and protein supplements have been linked to an increased risk of kidney stones. Additionally, dehydration and excessive sodium intake can also play a role.
In the case of the bodybuilder, his diet and hydration levels were monitored, and he reported drinking enough water during the creatine supplementation period. This may have helped prevent the formation of new kidney stones.

Based on the available evidence, creatine monohydrate supplementation does not appear to cause kidney stones in athletes, even those with a history of the condition. However, individuals with a history of kidney stones should consult a healthcare professional before starting creatine or any other supplement.
