Vitamin D for kids in India: why so many fall short, and what helps

It surprises most parents: India is one of the sunniest countries on earth, and yet studies have found vitamin D deficiency in roughly 70 to 90% of urban Indian children. If your child is indoors for school, tuition and screens, they are part of a very large group.

Why vitamin D matters for growing children

Vitamin D lets the body absorb the calcium it is given. Vitamin D3 and calcium together support healthy bones, and the years from 7 to 12 are when a great deal of bone is being laid down. Vitamin D also plays a part in normal immune function.

How much does a child need?

ICMR-NIN 2020 sets the Recommended Dietary Allowance for vitamin D at 15 micrograms (600 IU) a day for children. Very few foods carry much of it naturally, which is a large part of the problem.

Why city children miss out

• Time indoors. Classrooms, tuition and screens mean little midday sun on bare skin.
• Covered skin, sunscreen and pollution all reduce how much vitamin D the skin can make.
• Few natural food sources. Oily fish and egg yolks carry some; most vegetarian staples carry very little.

What helps

1. Outdoor play. Regular time outdoors with arms and legs uncovered helps the skin make vitamin D. Your paediatrician can advise on what is right for your child and your city.
2. Fortified foods. Look for vitamin D3 on the nutrition table, and check the %RDA column to see how much of the day one serving really covers.
3. Eggs and fish, where your family eats them.
4. Ask about testing. If you are worried, a simple blood test tells your doctor where your child stands.

Reading the label

Many products list vitamin D but deliver a small share of the day. One glass of Leap of Love Double Chocolate gives 15 mcg of vitamin D3, which is 100% of the day's requirement for children aged 7 to 9, alongside 330 mg of calcium (over half the day's need).
