Vitamin D and calcium: why they work together
Calcium builds bone, and vitamin D helps the body absorb it. Here is what that means in daily life.
2 November 2026
Calcium is the main mineral in your bones. Vitamin D helps your body absorb calcium from food, so the two work as a team.
Everyday sources
- Calcium: milk, curd, paneer, ragi, leafy greens and sesame seeds.
- Vitamin D: safe sunlight, fatty fish, eggs and fortified foods.
Do you need a supplement?
Some people need extra calcium or vitamin D, including many older adults, pregnant women and people with little sun exposure. A simple blood test and a talk with your doctor can show what is right for you. Avoid taking high doses without medical advice.
