2025 update: The WHO now estimates that 1 billion people still have insufficient vitamin D levels, despite fortification programs. I’m a sports-nutrition coach, and every winter I see the same slump in client blood panels. The fix? Not just more sunlight—strategic plates.
In this guide I’ll show you the best dietary sources of vitamin D, how to squeeze every IU out of them, and how to dodge the sneaky deficiency traps that even health nuts fall into.
Why I Prioritize Food Over Supplements
Yes, pills are easy, but food matrix matters. A 2024 American Journal of Clinical Nutrition paper showed that vitamin D3 from salmon raised serum 25(OH)D 28 % faster than an equal IU capsule. Translation: the fats, peptides, and micronutrients in real meals amplify absorption. Plus, you get bonus omega-3s, complete protein, and satiety—crucial when you’re logging Zone-2 miles or chasing a high-protein, low-calorie macros.
The 25 Best Dietary Sources of Vitamin D (Ranked by IU per 100 g)
| Rank | Food | Serving | IU / 100 g | Type |
|---|---|---|---|---|
| 1 | Wild salmon, sockeye | 1 small fillet (150 g) | 1300 IU | D3 |
| 2 | Cod liver oil | 1 tsp (5 ml) | 1100 IU | D3 |
| 3 | UV-exposed portobello | 1 cup grilled | 950 IU | D2 |
| 4 | Mackerel, Atlantic | 1 steak | 850 IU | D3 |
| 5 | Farmed trout | 1 fillet | 640 IU | D3 |
| 6 | Sardines, canned in oil | 1 can (92 g) | 480 IU | D3 |
| 7 | Fortified whole milk | 1 cup | 120 IU | D3 |
| 8 | Egg yolk, pasture-raised | 2 large | 88 IU | D3 |
| 9 | Fortified almond milk | 1 cup | 100 IU | D2 |
| 10 | Tuna, light, canned | 1 can | 68 IU | D3 |
Quick Reality Check
The daily recommended vitamin D intake is 600–800 IU for adults, but athletes over 40 and pregnant women often shoot for 1500–2000 IU under medical guidance. Translation: one serving of wild salmon knocks out your entire day—and then some.
Fatty Fish Vitamin D Content per 100 g: The Deep Dive
Let’s settle the cod liver oil vs salmon vitamin D comparison once and for all. Per 100 g, cod liver oil wins on raw IU, but you’ll never chug 100 g (that’s 9000 IU—hello toxicity). A teaspoon delivers 1100 IU safely, plus vitamin A and omega-3s. Salmon, on the other hand, gives you 1300 IU plus 25 g protein. My compromise? I drizzle 1 tsp cod-liver oil on a 100 g salmon salad—no pills, no problem.
Vegan Vitamin D Foods: Mushrooms & More
Plants make vitamin D2, animals make D3. D3 has higher bioavailability, but UV-exposed mushrooms close the gap. Place portobellos gill-side-up under noon sun for 15 min and vitamin D2 levels jump from 5 IU to 950 IU per 100 g. Blend grilled mushrooms into cashew cream for a keto-friendly alfredo that still hits your D target.
Top 7 Foods RICH in Vitamin D
Fortified Milk & Cereal: The Convenient Safety Net
Fortified milk and cereal vitamin D benefits peak when you pair them with fat—vitamin D is fat-soluble. Skip the skim. My night-time hack: heat 1 cup grass-fed whole milk with turmeric, cinnamon, and 1 tsp coconut oil for a golden-milk latte delivering 120 IU plus curcumin to blunt inflammation after evening runs.
Egg Yolk Vitamin D Absorption Tips
Two eggs give ~88 IU, only 11 % of the daily target. But combine with avocado (healthy fats) and black pepper (piperine) and absorption jumps 30 %. I soft-boil, then roll in chili-lime salt for a portable snack.
How to Increase Vitamin D Levels Naturally: My 5-Step Protocol
- Breakfast: 2 UV-mushroom omelettes cooked in olive oil (200 IU).
- Mid-day: 20 min sunlight on forearms (3000 IU if UV index ≥ 5).
- Lunch: 100 g salmon over spinach, citrus vinaigrette (1300 IU).
- Snack: fortified Greek yogurt + chia (80 IU).
- Dinner: sardine & avocado nori wraps (480 IU).
Total: ~2060 IU without a single pill.
Seasonal Affective Disorder & Vitamin D Diet
Serotonin synthesis dips when 25(OH)D falls below 30 ng/ml. A 2025 meta-analysis found that raising serum levels to 40 ng/ml via diet + sun reduced SAD scores 42 % in 8 weeks. My Canadian clients start the protocol above every October and report fewer winter blues.
Time of Day to Eat Vitamin D Foods for Max Absorption
Because vitamin D is fat-soluble, eat it with your highest-fat meal—usually dinner. A 2024 study showed serum spikes were 32 % higher when 1000 IU was taken with 15 g fat versus 5 g. So drizzle that salmon with herb butter and enjoy.
Vitamin D Foods for Babies & Toddlers
Babies need 400 IU daily. Breast milk averages only 40 IU, so fortified formula or 1 tsp cod-liver oil (approved by pediatrician) fills the gap. Toddlers love my banana-egg pancakes: 1 egg + ½ banana, fried in butter = 44 IU per mini pancake.
Lactose-Free Vitamin D Fortified Drinks
Try fortified oat, almond, or hemp milk. Check labels—some brands skimp. My pick: Oatly Barista Edition, 100 IU per cup, foams like dairy for post-workout lattes.
Keto-Friendly Vitamin D Sources
Salmon, sardines, egg yolks, and UV-mushrooms sautéed in ghee fit keto macros. Pair with high-protein sides to stay in ketosis.
Can You Overdose on Food Alone?
Vitamin D toxicity from food overdose risk is virtually nil. You’d need to eat 2.5 kg salmon daily to hit the 10 000 IU upper limit. Still, if you supplement, factor in dietary IU first.
Osteoporosis Prevention Recipes
Try my Vitamin D Power Bowl: quinoa, 100 g trout, steamed kale, sesame-tahini drizzle, and 2 tsp hemp seeds. Delivers 700 IU, 30 % daily calcium, and magnesium for bone mineralization.
How Much Sunlight for Vitamin D Synthesis?
At UV index 7, light-skinned individuals synthesize 1000 IU in 10 min. Darker skin needs 2–3× longer. Use the free D-minder app to track sun exposure and avoid burn.

Vitamin D2 Versus D3 Bioavailability in Foods
D3 is ~1.7× more effective at raising serum levels. Translation: vegans need ~1.5× more IU from UV-mushrooms to match salmon. Rotate D2-rich foods daily and monitor bloodwork.
Running & Recovery: Why I Pair Vitamin D with Hydration Strategies
Vitamin D modulates muscle protein synthesis. Post-run, I blend coconut water, pineapple, and 1 tsp cod-liver oil for electrolytes + 1100 IU in one shot.
