Vitamin D3 deficiency is quietly common across Pakistan, and the numbers are striking. The National Nutrition Survey 2018 found that 54% of women of reproductive age in Pakistan are vitamin D deficient, and a study published in BMC Women’s Health found that 57% of women in Karachi had deficient levels despite living in one of the sunniest cities in the world. The paradox is real: abundant sunshine, yet chronically low vitamin D.
The reason is not just sun avoidance. Most Pakistanis eat a diet built around roti, dal, chawal, and sabzi, which are nutritious staples but naturally low in vitamin D3 (cholecalciferol), the form the body uses most efficiently. Darker skin tones, which are common across South Asia, also reduce how much vitamin D the skin synthesises from sunlight, meaning food sources matter more than most people realise.
Knowing which foods actually contain meaningful amounts of vitamin D3, and how to fit them into a typical Pakistani diet, is the practical starting point for fixing the gap.

What Is Vitamin D3 and Why Do Pakistanis Need It?
Vitamin D3, also called cholecalciferol, is the form of vitamin D that the body produces when skin is exposed to UVB sunlight, and the same form found in animal-based foods. It’s more effective at raising blood vitamin D levels than vitamin D2 (ergocalciferol), which comes mainly from plant sources.
Beyond bone health, vitamin D3 helps regulate calcium and phosphorus absorption, supports immune function, and plays a role in muscle strength. Deficiency over time can lead to osteomalacia (softening of bones) in adults and rickets in children, both of which are still seen in Pakistani clinical practice. Nutritionists at Marham frequently flag low vitamin D as one of the most commonly missed deficiencies in routine blood work across Lahore, Karachi, and Islamabad.
Key Takeaways
- Vitamin D3 (cholecalciferol) is the most bioavailable form, found in animal foods and made by skin in sunlight.
- Pakistan’s NNS 2018 found 54% of women of reproductive age are vitamin D deficient.
- Fatty fish (sardines, mackerel, trout) are the richest dietary sources of D3 available in Pakistan.
- Egg yolks, beef liver, and fortified milk are practical everyday options.
- Vitamin D3 is fat-soluble: eat these foods with a small amount of fat for better absorption.
- A 25-hydroxyvitamin D blood test (available at most labs in Pakistan for around Rs 1,500 to Rs 2,500) is the only reliable way to know your actual levels.
Top Vitamin D3 Rich Foods and Their IU Values
The foods below are ranked by the amount of vitamin D3 they naturally provide per standard serving, based on data from the USDA FoodData Central (2019) and published nutrition literature.
1. Fatty Fish: Sardines, Mackerel, and Trout
Fatty fish are the single richest natural source of vitamin D3 in any diet. Sardines (called chooti machli or palla in parts of Sindh) are widely available in Pakistan, both fresh and canned. A 100g serving of canned sardines provides roughly 270 to 380 IU of vitamin D, according to USDA data. Mackerel (bangda) is sold at most fish markets in Karachi and coastal cities and provides a comparable amount. Rainbow trout, increasingly available in Islamabad and Lahore supermarkets, provides around 645 IU per 85g serving according to USDA figures.
Salmon is often cited in global articles but is expensive and not widely stocked in local wet markets. For most Pakistani households, sardines and mackerel are the practical, affordable choices. Baking or grilling the fish with a small amount of ghee or cooking oil helps absorption, since vitamin D3 is fat-soluble.
2. Cod Liver Oil
Cod liver oil is one of the most concentrated sources, providing around 1,360 IU per tablespoon, according to USDA data. It’s available at pharmacies in Pakistan in capsule or liquid form. One important caution: cod liver oil is also very high in vitamin A, and taking large amounts can cause vitamin A toxicity. Limit use to less than one teaspoon per day if using the liquid form, and consult a doctor before adding it to a child’s routine.
3. Egg Yolks
Eggs are a daily staple in Pakistani households, and the yolk is where the vitamin D lives. One large egg yolk contains roughly 40 to 50 IU of vitamin D3, per USDA data. That’s modest on its own, but two to three eggs a day across anda paratha, omelette, or fried eggs adds up meaningfully. Free-range or desi eggs from chickens that have outdoor access tend to have higher D3 content than commercially farmed eggs, because the hen’s own sun exposure affects the yolk.
4. Beef Liver (Kaleji)
Kaleji is a well-loved part of Pakistani cuisine, eaten at Eid, in karahi, and at roadside dhabas. A 100g serving of beef liver provides roughly 40 to 50 IU of vitamin D3 alongside significant amounts of iron, vitamin B12, and zinc. It’s not a high-dose source, but it contributes to overall intake. People with cardiovascular disease or fatty liver should moderate their kaleji intake because of its cholesterol content.
5. Fortified Milk and Dairy
Milk does not naturally contain much vitamin D3, but many brands available in Pakistan now fortify their products. A cup (240ml) of fortified cow’s milk typically contains around 100 to 120 IU of vitamin D, per USDA data. Check the nutrition label on packaged milk brands sold in supermarkets across Lahore and Karachi: look for the words “fortified with vitamin D” or “vitamin D added.” Loose milk from a local doodhwala is generally not fortified.
6. Mushrooms (Sun-Exposed)
Mushrooms are the only meaningful plant-based source of vitamin D, though they produce mostly D2 rather than D3. Commercially grown mushrooms kept in dark storage contain very little. However, placing fresh mushrooms gill-side up in direct midday sunlight for 15 to 20 minutes can substantially boost their vitamin D content. This is a practical tip for Pakistani households, given the abundant sunshine available for most of the year outside of monsoon season.

How to Add Vitamin D3 Rich Foods to a Pakistani Diet
Fitting these foods into everyday Pakistani meals is simpler than it sounds. Here’s a practical approach:
- Start with eggs at breakfast. Two anda (eggs) at sehri or breakfast, cooked as you like, give you 80 to 100 IU before the day begins. Desi eggs from a local poultry market are a slightly better option.
- Add canned sardines to your weekly grocery run. A can of sardines from any Imtiaz or Metro store costs around Rs 150 to Rs 250 and provides a solid dose of D3. Mash them with lemon and green chilli and eat on roti for a quick meal.
- Cook kaleji once a week. Eid is not the only time for kaleji. A small serving once or twice a week adds D3, iron, and B12 to your diet without overloading on cholesterol.
- Switch to fortified packaged milk. When buying doodh, choose a packaged brand that states vitamin D fortification on the label. Two glasses a day adds roughly 200 to 240 IU.
- Sun your mushrooms before cooking. Buy fresh mushrooms from a supermarket, place them gill-side up in sunlight for 20 minutes before the afternoon cooking session, then use them in your sabzi or omelette.
- Use cod liver oil capsules carefully. If fish is not a regular part of your diet, one cod liver oil capsule daily (not a tablespoon of liquid) is a reasonable supplement, but check with a doctor first, especially if you are pregnant.
- Pair vitamin D foods with a fat source. Vitamin D3 is fat-soluble, meaning it absorbs best when eaten with some fat. Cooking fish in a little oil or ghee, or eating eggs with their yolk intact, naturally handles this.
Why Sun Alone Is Not Enough in Pakistan
Pakistan gets plenty of sunlight, yet deficiency rates remain high. Several factors explain this. Darker skin tones, common across South Asia, require longer sun exposure to produce the same amount of vitamin D3 as lighter skin, because melanin reduces UVB penetration, as noted by researchers at Harvard T.H. Chan School of Public Health. Women who remain largely indoors, wear full-coverage clothing, or apply high-SPF sunscreen get minimal synthesis. Winter months in cities like Islamabad and Peshawar also reduce UVB intensity. Food sources therefore cannot be treated as optional supplements; for many Pakistani families, they are the primary reliable route.
Who Should Be Careful
Vitamin D3 is fat-soluble, meaning the body stores it rather than excreting excess amounts quickly. Toxicity from food sources alone is essentially impossible, but taking very high-dose supplements without medical supervision can lead to hypercalcemia (excess calcium in the blood), which may cause nausea, weakness, and in severe cases kidney problems. People with kidney disease, sarcoidosis, or certain lymphomas should not take vitamin D supplements without a doctor’s guidance, as their bodies may process it differently.
Pregnant women should note that beef liver is high in vitamin A, which can be harmful in large amounts during pregnancy. Stick to eggs, fortified milk, and fish as the safer D3 sources during pregnancy.
When to See a Doctor About Vitamin D Deficiency
Symptoms of deficiency can be vague: persistent fatigue, bone aches, muscle weakness, and a tendency to fall sick frequently. These overlap with many other conditions, so symptoms alone are not diagnostic. The only reliable way to know your vitamin D status is a 25-hydroxyvitamin D blood test, which most labs in Pakistan offer for around Rs 1,500 to Rs 2,500. If your result is below 20 ng/mL, clinical guidelines generally classify this as deficiency. A result between 20 and 29 ng/mL is considered insufficient by many clinicians.
If you’ve been experiencing bone pain, unexplained fatigue, or frequent infections and suspect a deficiency, it’s worth getting checked. Consulting a nutritionist in Pakistan can help you build a diet plan that addresses the gap before a supplement prescription becomes necessary. For patients with confirmed deficiency, an endocrinologist or general physician will typically guide the supplement dose based on your blood results, not a fixed number from the internet.

Get Expert Dietary Advice from Marham
Many Pakistanis discover their vitamin D deficiency only after a routine blood test ordered for something else entirely. By that point, levels can be quite low and diet alone may not be enough to correct them quickly. If you’re unsure whether your diet is covering your needs, or if you’ve already received a low vitamin D result and don’t know what to do next, speaking to a specialist is the sensible next step.
Marham connects you with verified nutritionists in Pakistan who consult online from anywhere in the country, including cities where specialist access is limited. A short online consultation, typically 15 to 20 minutes, can help you understand whether your current diet is adequate, whether a supplement is needed, and what dose is appropriate for your age and health status. You don’t need to wait for symptoms to become serious before asking.
Frequently Asked Questions
Which food has the highest vitamin D3 content?
Cod liver oil is the most concentrated single source, providing around 1,360 IU per tablespoon according to USDA data. Among whole foods eaten regularly in Pakistan, fatty fish like sardines and mackerel come closest, offering 250 to 380 IU per 100g serving.
Can I get enough vitamin D from food alone?
For most people, food alone is unlikely to meet the full daily requirement of 600 IU (for adults under 70), especially in a typical Pakistani diet. A combination of moderate sun exposure, regular consumption of vitamin D3 rich foods, and a supplement if blood levels are low is the most reliable approach.
What are the symptoms of vitamin D deficiency?
Common symptoms include fatigue, bone aches, muscle weakness, and getting sick frequently. These are non-specific and overlap with many other conditions, so a 25-hydroxyvitamin D blood test is the only reliable way to confirm deficiency rather than guessing from symptoms.
Is egg yolk a good source of vitamin D3?
Yes, though the amount is modest. One large egg yolk provides roughly 40 to 50 IU of vitamin D3. Eating two to three eggs daily contributes meaningfully to overall intake, and desi or free-range eggs tend to have slightly higher levels than commercially farmed ones.
Which vegetables are rich in vitamin D?
Almost no vegetables naturally contain vitamin D3. Mushrooms exposed to UV sunlight are the only plant-based source, and they produce mainly vitamin D2 rather than D3. Placing fresh mushrooms in direct sunlight for 15 to 20 minutes before cooking can increase their vitamin D content noticeably.
How much vitamin D do I need per day?
For most adults aged 19 to 70, the Recommended Dietary Allowance (RDA) set by the US National Institutes of Health is 600 IU per day, rising to 800 IU for those over 70. People with confirmed deficiency may need higher doses under medical supervision. Do not self-prescribe high-dose supplements without a blood test.
When is the best time to take vitamin D supplements?
Taking vitamin D with your largest meal of the day, which typically contains some fat, tends to improve absorption. Morning or midday is generally preferred. Some healthcare providers suggest avoiding it at night, though the evidence on this is not definitive.
Conclusion
For Pakistani families, the vitamin D3 gap is real but fixable with a few targeted food choices. Sardines, mackerel, eggs, kaleji, and fortified packaged milk are all accessible, affordable, and meaningful contributors to daily intake. No single food solves the problem on its own, but combining two or three of these regularly, alongside sensible sun exposure, moves the needle. If you have reason to suspect your levels are low, a simple blood test is the clearest first step.
