Are You Vitamin D Deficient? Signs, Symptoms, and What to Eat
Vitamin D is often called the "sunshine vitamin" — but millions of people are deficient in it, even those living in
sunny countries like Pakistan and UAE. If you constantly feel tired, your bones ache, or you get sick frequently, your
vitamin D levels may be the hidden culprit.
Why Vitamin D Matters More Than You Think
Vitamin D is not just a vitamin — it functions like a hormone in your body. Nearly every cell has receptors for it. It
plays a critical role in:
Bone strength — helps your body absorb calcium properly
Immune system — low levels are linked to frequent infections and slow recovery
Mood and mental health — deficiency is strongly linked to depression and anxiety
Muscle function — weakness and fatigue are early warning signs
Hormonal balance — especially important for women with PCOS and thyroid issues
Heart health — linked to blood pressure regulation
Who Is at Highest Risk?
You might assume vitamin D deficiency only affects people in cold, cloudy countries. But that is not the case.
Research shows that deficiency rates in Pakistan are between 70–80%, and in UAE over 60%, despite abundant sunshine.
This is because:
Most people spend the majority of their day indoors
Traditional clothing covers most of the skin
Dark skin pigmentation reduces vitamin D synthesis from sunlight
High-rise buildings and car culture reduce outdoor time
Diet is often low in vitamin D-rich foods
If you live in the UK or Canada, seasonal deficiency is almost guaranteed in winter months when sunlight is weak.
Signs You May Be Deficient
Physical Signs
Fatigue that does not improve with rest
Bone pain, especially in the back, hips, and legs
Muscle weakness or cramps
Frequent colds, flu, or infections
Slow wound healing
Hair loss
Mental and Emotional Signs
Low mood or depression
Anxiety or irritability
Brain fog and difficulty concentrating
Poor sleep quality
Important: These symptoms overlap with many conditions. The only way to confirm deficiency is a blood test. Ask your
doctor for a 25(OH)D test. Optimal levels are between 40–60 ng/mL.
Vitamin D and Pakistani Women: A Special Concern
Women who wear full hijab or niqab, spend most time indoors, or have darker skin are at significantly higher risk.
Vitamin D deficiency in women is linked to:
Worsening PCOS symptoms
Irregular periods
Difficulty conceiving
Increased risk of gestational diabetes during pregnancy
Postpartum depression
Osteoporosis after menopause
If you are a woman experiencing any hormonal issues, getting your vitamin D tested should be your first step.
Foods That Provide Vitamin D
Diet alone rarely fixes a serious deficiency — sunlight and supplements are usually needed. But these foods help
maintain your levels:
Animal Sources (Best Absorbed)
Fatty fish — salmon, mackerel, sardines (400–600 IU per 100g serving)
Egg yolks — 40 IU per yolk; do not discard the yolk
Liver — beef or chicken liver is a good source
Full-fat dairy — milk, yogurt, cheese contain small amounts
Fortified Foods
Fortified milk — many packaged milks now add vitamin D
Fortified cereals — check the label
Some orange juices — if fortified
Desi Foods That Help
Machli (fish) — any variety, especially oily fish cooked with minimal processing
Anda (eggs) — whole eggs, not just whites
Ghee — small amounts contain fat-soluble vitamins including D
Dahi (yogurt) — especially if made from full-fat milk
How to Maximize Vitamin D From Sunlight
Even 15–20 minutes of direct sunlight on your arms and legs between 10am and 2pm can significantly boost your levels.
Tips:
Do not apply sunscreen during this short window
Glass windows block UV rays — you must be outdoors
Morning walks are good for overall health but weak sunlight early morning produces minimal vitamin D
Midday sun (despite feeling harsh) is when UV-B rays are strongest
Should You Take a Supplement?
If your blood test shows deficiency, a supplement is the fastest and most reliable fix. Common recommendations:
Mild deficiency: 1000–2000 IU daily
Moderate deficiency: 2000–4000 IU daily
Severe deficiency: Your doctor may prescribe a high-dose weekly tablet (50,000 IU)
Always take vitamin D supplements with a meal containing fat — it is a fat-soluble vitamin and absorbs much better
with food. Pair it with vitamin K2 if possible, as it helps direct calcium to your bones instead of arteries.
The Bottom Line
Vitamin D deficiency is silently affecting millions of people across South Asia and beyond. The good news is it is
completely correctable. Start with a blood test, increase your intake of vitamin D-rich foods, get some midday
sunlight, and speak to a nutritionist or doctor about whether supplementation is right for you.
Small consistent actions — a daily egg, a piece of fish, 15 minutes of sunlight — add up to make a real difference in
how you feel.
