Micronutrients & recovery
Dietary calcium intake reduces the risk of kidney stones, whereas supplemental calcium intake (especially without meals) may increase the risk.
If you are prone to kidney stones, prioritize getting calcium from food sources like dairy or leafy greens. If you must take supplements, take them with meals to help bind oxalate, as taking them between meals may increase your risk of stone formation.
GoodQualifiesHIGH confidence
high intake of dietary calcium or supplemental calcium (>500 mg/d) could lower urinary oxalate levels, subsequently decreasing the risk of kidney stones formation... high dietary calcium could reduce the risk of kidney stones, whereas the risk would be increased in women with high supplemental calcium.
Why this rating
Supported by large prospective studies and mechanistic explanations, though some small trials show no significant effect.
