Vitamin D and bone nutrition in IBD

Low vitamin D is common in IBD. Bone health also depends on calcium intake, weight-bearing activity when safe, inflammation control, and steroid history.

Why vitamin D matters

Vitamin D supports bone mineralization and is often repleted when labs are low.

Sunlight, fortified foods, and supplements may all play roles; dosing should follow labs and clinician advice.

Calcium food sources

Dairy if tolerated, fortified alternatives, canned fish with bones, and tofu set with calcium are frequent options.

If dairy triggers symptoms, plan alternatives with a dietitian rather than dropping calcium entirely.

Steroids and screening

Repeated systemic steroids raise bone-loss risk.

Ask about DEXA timing and steroid-sparing plans.

Practical tips

• Recheck vitamin D rather than guessing high doses
• Pair with bone health article
• Mention fracture history and menopause status at visits

Common questions

What vitamin D level should I target?

Targets vary by lab and clinician. Ask for your number and the plan to recheck after repletion.

Do I need calcium pills if I eat dairy?

Not always. Total intake from food and supplements matters. Your team personalizes this, especially with kidney stone history.
