Why is vitamin D deficiency so common in Pakistan?
It seems surprising in such a sunny country, but studies consistently find high rates of vitamin D deficiency across Pakistan. The main reasons are limited direct skin exposure to sunlight (clothing, indoor lifestyles, heat avoidance), widespread sunscreen use, urban air pollution that blocks UVB, and naturally darker skin that produces vitamin D more slowly.
What are the signs of low vitamin D?
- Persistent tiredness and low energy
- Bone pain and muscle aches or weakness
- Frequent colds and infections (weaker immunity)
- Low mood, especially in winter
- Hair thinning and slow wound healing
These symptoms overlap with many conditions, so a blood test (25-hydroxy vitamin D) is the only way to confirm deficiency.
How do I get more vitamin D?
1. Sensible sunlight
Short, regular exposure of the arms and face to midday sun helps the skin make vitamin D. Balance this with skin-cancer and heat precautions.
2. Food sources
Few foods are naturally rich in vitamin D. Fatty fish, egg yolk and fortified milk or cereals contribute small amounts. Omega-3 fish oil supplements often provide some vitamin D too.
3. Supplements
For most people with deficiency, a daily vitamin D supplement or a complete multivitamin is the reliable way to restore and maintain levels. Your doctor may prescribe a higher weekly dose to correct a confirmed deficiency, followed by a maintenance dose.
Everyday sources compared
| Source | Reliability | Notes |
|---|---|---|
| Sunlight | Variable | Depends on exposure, skin, pollution |
| Diet | Low | Few foods are naturally rich in vitamin D |
| Daily supplement / multivitamin | High | Consistent, easy to dose |
Who is most at risk?
Women who cover most of their skin, older adults, people who work indoors, pregnant and breastfeeding women, and anyone with darker skin are at higher risk and may benefit most from testing and supplementation.
