Calcium supplements appear to increase the risk of kidney stones (American Journal of Clinical Nutrition, Jul. 2011). Some people make more kidney-stone forming oxalate after large doses (2,000 mg) of vitamin C (Journal of Nutrition, Jul. 2005).
Other types of stones, and their underlying causes, include: 1  Struvite stones: Found more often in women, these are almost always the result of urinary tract infections. 2  Uric acid stones: These are a byproduct of protein metabolism. 3  Cystine stones: Represent a very small percentage of kidney stones.
