❓ Frequently Asked Questions
Should I avoid calcium if I have calcium oxalate stones?
No — that's outdated advice. Dietary calcium actually binds oxalate in your gut, reducing absorption. Aim for 1,000-1,200 mg from food, not supplements.
What's the difference between food calcium and supplement calcium?
Calcium from food is protective — it binds oxalate in your digestive tract. Calcium supplements taken between meals may actually increase stone risk. Get calcium from food when possible.
How much calcium do I need?
The NKF recommends 1,000-1,200 mg of dietary calcium daily. The foods on this page help you get there from real food sources.
This is dietary reference information, NOT medical advice. Talk to your doctor or a registered dietitian before changing your diet. Oxalate tolerance varies by person, stone type, and medication.
