Vitamin D

Nutrition & Diet

Vitamin D helps the body absorb calcium and keeps bones, muscles, nerves, and the immune system working. Despite year-round sunshine, 70–80% of urban Indians are vitamin D deficient — it is probably our most common vitamin shortfall.

Also known as: Cholecalciferol, Ergocalciferol

About Vitamin D

About this summary: Written by Swasthya Plus for Indian readers, using MedlinePlus, National Library of Medicine as a reference source. For personal guidance, please consult a qualified Health Expert.

Vitamin D helps the body absorb calcium and keeps bones, muscles, nerves, and the immune system working. Despite year-round sunshine, 70–80% of urban Indians are vitamin D deficient — it is probably our most common vitamin shortfall.

Why Indians are short on it

  • Indoor work, long hours at screens, little outdoor time.
  • Darker skin needs 3–5× longer sun exposure than lighter skin to make the same vitamin D.
  • Traditional clothing and religious practice that cover most skin.
  • Urban air pollution cuts UV-B reaching the skin.
  • Diets low in fish, eggs, and fortified dairy — especially in pure vegetarians.
  • Older adults make less vitamin D from sun even with exposure.

How to get enough

  • Sunlight: 15–30 minutes on arms and face between 10 am and 3 pm, most days, without sunscreen on that area. Early morning and late evening sun has little UV-B.
  • Food: oily fish (rawas/salmon/sardines), egg yolks, mushrooms, fortified milk and curd.
  • Supplement if confirmed deficient on a blood test. Don't start high-dose vitamin D on your own — it is fat-soluble and toxic in excess.

Daily requirement

  • Infants 0–12 months: 400 IU.
  • Children, teens, adults up to 70: 600 IU.
  • Adults over 70: 800 IU.
  • Pregnant/breastfeeding: 600 IU (often more, doctor-guided).

When to get tested

  • Bone pain, muscle weakness, unexplained fatigue.
  • Osteoporosis or a fracture without much trauma.
  • Chronic kidney or liver disease, malabsorption (coeliac, Crohn's, after weight-loss surgery).
  • In pregnancy, or in infants who are exclusively breastfed.
