Only a few foods naturally contain much vitamin D. Salmon and trout are the strongest everyday sources; eggs and UV-exposed mushrooms add smaller or variable amounts. In the US, fortified milk, plant milks, and breakfast cereals often supply much of what children get from food. The amounts below describe vitamin D in food, not a child's vitamin D level. NIH vitamin D reference

That short list changes the shopping question. With iron or calcium, a varied plate usually includes several useful sources. With vitamin D, many ordinary foods—bread, rice, beans, fruit, most vegetables—contain essentially none, so it helps to know exactly which items on the list are doing the work.

For an explanation of what vitamin D does and the daily reference amounts by age, see our existing vitamin D guide.

Natural sources: the short list

These approximate values come from the NIH food table. Its reference portions are standard comparison amounts, often larger than a young child eats; the portion section below shows how to scale them.

Vitamin D in foods that contain it naturally: reference portions
FoodReference portionApproximate vitamin D
Rainbow trout, farmed, cooked3 ounces, about 85 g16.2 mcg
Sockeye salmon, cooked3 ounces, about 85 g14.2 mcg
White mushrooms exposed to UV light, raw, sliced½ US cup9.2 mcg
Atlantic sardines, canned in oil, drained2 sardines1.2 mcg
Egg, scrambled1 large1.1 mcg
Light tuna, canned in water, drained3 ounces, about 85 g1.0 mcg
Cheddar cheese1.5 ounces, about 43 g0.4 mcg

Values: NIH Office of Dietary Supplements, Vitamin D: Table 3. The same table lists ½ cup of raw portabella mushrooms that were not UV-treated at 0.1 mcg, and chicken breast at 0.1 mcg per 3 ounces.

The mushroom line depends on how the mushrooms were grown or treated. Ordinary mushrooms contain very little; look for packaging that says the mushrooms were exposed to UV light or are a source of vitamin D.

Fortified foods: where much of it comes from

Vitamin D in fortified foods: reference portions
FoodReference portionApproximate vitamin D
Milk, 2% fat, vitamin D fortified1 US cup2.9 mcg
Soy, almond, or oat milk, vitamin D fortified1 US cup2.5–3.6 mcg, depending on brand
Breakfast cereal fortified with 10% of the Daily Value1 serving2.0 mcg

Source: NIH vitamin D food table. Fortification is a product decision, not a property of the food category. Two oat drinks, or two cereals, on the same shelf can differ.

These figures describe US products. In the UK, cows' milk is generally not fortified with vitamin D, so the milk value above does not transfer to a UK carton. NHS: sources of vitamin D

Read the label: from %DV to micrograms

US Nutrition Facts labels list vitamin D in micrograms and as a percent Daily Value (%DV). On a standard label, the Daily Value for vitamin D is 20 mcg. FDA: Daily Values on food labels

That number is not the same as a child's reference amount. The US Recommended Dietary Allowance for children aged 1 to 18 is 15 mcg a day, so %DV understates how much of a child's reference amount a serving represents.

For a fictional example, an oat drink labeled 10% DV per 1-cup serving contains about 2 mcg. If your child drinks half a cup, count about 1 mcg—not the full label amount. Nutrient figures scale with the portion consumed. FDA label guide

If you switch brands, check the vitamin D line again. A new carton can look the same and contain a different amount, or none.

Scale the portion to your child

The FDA's fish advice for children suggests serving sizes of about 1 ounce at ages 1 to 3, 2 ounces at ages 4 to 7, 3 ounces at ages 8 to 10, and 4 ounces from age 11, with two servings a week from its “Best Choices” list. Salmon, sardines, freshwater trout, and canned light tuna are all on that list. FDA and EPA advice about eating fish

Using the NIH value for salmon, a 2-ounce serving for a 5-year-old works out to about 14.2 × 2 ÷ 3 ≈ 9.5 mcg. A 1-ounce serving for a 2-year-old is about 4.7 mcg.

Now a day without fish: 1 cup of fortified milk (2.9 mcg), a serving of cereal fortified at 10% DV (2.0 mcg), and a scrambled egg (1.1 mcg) add up to about 6.0 mcg. That is roughly 40% of the 15 mcg reference—from a day that already includes three of the more useful foods.

The arithmetic explains why fish and fortified foods matter. It does not show that a child is short of vitamin D. The reference amount assumes minimal sun exposure, and a child's vitamin D status depends on more than one day's food. NIH: vitamin D intake and status

Five ways to bring these foods to the table

Salmon in something familiar. Flake cooked salmon into pasta with a mild sauce, or shape it into fishcakes with mashed potato. Check carefully for bones.

Sardines on toast. Mash canned sardines with a little butter or cream cheese and spread thinly. Mash well and remove any bones you can find, especially for younger children.

Eggs more than once a week. Scrambled eggs, an omelet with cheese, or egg fried rice. One egg is a modest contribution, but an accepted one is useful.

UV-exposed mushrooms in sauce. Chop them finely into a tomato or meat sauce for pasta. Check the packaging, since ordinary mushrooms add very little.

A fortified breakfast pair. A cereal with vitamin D on the label, served with fortified milk or a fortified plant drink, gives two sources in one bowl. Confirm both labels rather than assuming.

Adapt texture and size to your child's eating skills. CDC: food preparation and choking

Sunlight, seasons, and supplements

Food is only one source. The skin makes vitamin D in sunlight, but the amount varies with season, latitude, time outdoors, clothing, sunscreen, and skin pigmentation, and sun exposure carries skin-cancer risk. In the UK, the NHS says sunlight between October and early March is not strong enough for the body to make enough vitamin D. NHS: vitamin D and sunlight

Public-health advice on supplements differs by country and age. The NHS, for example, advises a daily vitamin D supplement for children aged 1 to 4 throughout the year, and advises everyone older to consider one in autumn and winter. US advice is framed differently. Ask your pediatric clinician what applies to your child.

This guide does not recommend a supplement dose. More is not always better: too much vitamin D from supplements over time can cause harmful calcium buildup. NHS: taking too much vitamin D

Can a food log tell me my child's vitamin D level?

No. A food record can show which vitamin D sources your child regularly eats, but it cannot measure vitamin D status. If you are concerned about your child's diet, growth, bones, or time outdoors, talk to a pediatric clinician.

A useful first shopping list could be one fish your family will eat, eggs, and a milk or plant drink and cereal with vitamin D on the label.
