Calcium keeps bones and teeth strong, and needs are higher in growing children, pregnancy and older age. Vitamin D is essential to absorb it, so the two go together.
Get enough vitamin D (sun + food) to absorb calcium
When to see a doctor urgently
Bone pain, easy fractures or loss of height (possible osteoporosis)
Numbness, tingling or muscle cramps (possible low calcium)
Very high-dose calcium supplements without advice (kidney-stone risk)
Calcium needs vitamin D. Calcium and vitamin D work together for bone health. Supplements help when diet and sun are not enough, especially in menopause and older age. MedDroid gives general information, not a personalised plan.
Frequently asked questions
Which foods are high in calcium?
Milk, curd, paneer and cheese are richest; vegetarian options include ragi, sesame seeds, almonds, tofu and green leafy vegetables.
How much calcium do I need?
Roughly 1000 mg a day for most adults, more in older age and pregnancy. Get it from food first, with supplements if needed.
Why do I need vitamin D with calcium?
Vitamin D helps the body absorb calcium — without enough, even a calcium-rich diet does not protect bones well.
