Vitamin D Foods: 8 Best Sources for Better Health
Vitamin D foods include fatty fish, egg yolks, certain mushrooms, and products fortified with vitamin D. This nutrient helps your body absorb calcium and supports healthy bones. It also plays a role in normal muscle and immune function. Few foods naturally contain large amounts of vitamin D. Some products, such as milk, breakfast cereals, and plant-based drinks, may contain added vitamin D. Knowing which foods provide this nutrient can help you make informed choices and maintain a balanced diet. What Is Vitamin D? Vitamin D is a fat-soluble vitamin that helps the body absorb calcium and maintain normal calcium and phosphorus levels. These minerals are important for healthy bones and teeth. There are two main forms of vitamin D: Both forms can increase vitamin D levels in the body. The amount you get from food depends on the type of food, serving size, and whether the product has been fortified. Why Does Your Body Need Vitamin D? Vitamin D has several important functions. Supports Bone Health Vitamin D helps the intestines absorb calcium from food. Calcium and phosphorus help build and maintain bones. Severe vitamin D deficiency can cause rickets in children and osteomalacia in adults. Both conditions affect bone health. Helps Maintain Muscle Function Vitamin D plays a role in normal muscle function. Severe deficiency can contribute to muscle weakness, although muscle symptoms can have many other causes. Supports Normal Immune Function Vitamin D also contributes to normal immune system function. However, getting extra vitamin D does not guarantee protection against infections. The main established nutritional role discussed here is its contribution to bone health and calcium absorption. 8 Best Food Sources of Vitamin D Adding foods that contain vitamin D to your meals can help increase your dietary intake. The following options include natural sources and products that may contain added vitamin D. 1. Fatty Fish Fatty fish are among the best natural food sources of vitamin D. They also provide protein and other nutrients. Examples include: The vitamin D content varies by fish type and serving size. According to the US National Institutes of Health (NIH), a 3-ounce serving of cooked sockeye salmon provides about 570 IU (14.2 micrograms) of vitamin D. The same serving size of cooked rainbow trout provides about 645 IU (16.2 micrograms). Fish can be prepared in different ways, including baking, grilling, or cooking in a curry. The vitamin D content of a meal will depend on the fish used and the serving size. 2. Egg Yolks Egg yolks contain small amounts of vitamin D. The amount can vary depending on the hen’s diet and other factors. According to NIH food data, one large scrambled egg provides about 44 IU (1.1 micrograms) of vitamin D. Eggs are also a source of protein and other nutrients. You can include boiled eggs, scrambled eggs, or omelets in a balanced diet. However, eggs generally provide less vitamin D per serving than fatty fish. 3. Fortified Milk Some milk products contain added vitamin D. This process is called fortification, which means that a nutrient is added to a food during production. In the United States, many milk products are fortified with vitamin D. One cup of fortified 2% milk provides about 120 IU (3 micrograms), according to NIH data. However, milk fortification varies between countries and brands. Do not assume that every milk product contains added vitamin D. Check the nutrition label to see whether the product provides this nutrient. 4. Fortified Plant-Based Milk Plant-based drinks may also provide vitamin D when manufacturers add it during production. Examples include: The amount varies by brand. Some products contain added vitamin D, while others do not. For example, NIH data for selected fortified plant-based drinks lists approximately 100–144 IU (2.5–3.6 micrograms) per cup. These values do not apply to every product. Check the nutrition label before choosing a plant-based drink as a vitamin D source. 5. Mushrooms Mushrooms can provide vitamin D2. Their vitamin D content varies according to the type of mushroom and its exposure to ultraviolet light. Some commercially available mushrooms are exposed to UV light to increase their vitamin D content. NIH data lists about 366 IU (9.2 micrograms) in half a cup of sliced white mushrooms exposed to UV light. Ordinary mushrooms may contain much less. For this reason, do not assume that all mushrooms provide the same amount of vitamin D. Mushrooms can be added to soups, omelets, vegetable dishes, and other meals. When available, check the packaging for information about UV treatment and vitamin D content. 6. Fortified Breakfast Cereals Some breakfast cereals contain added vitamin D. The amount depends on the product and the level of fortification. For example, the NIH lists approximately 80 IU (2 micrograms) per serving for a ready-to-eat cereal fortified with 10% of the US Daily Value for vitamin D. This figure applies to that stated fortification level, not every breakfast cereal. Check the nutrition label for vitamin D per serving. It is also useful to compare sugar and fiber content when selecting a cereal. 7. Fortified Orange Juice Some orange juice products contain added vitamin D, but many do not. If you want orange juice to contribute to your vitamin D intake, check the product label. The amount can vary between brands, so there is no single value that applies to every serving. Fortified orange juice can contribute to your daily intake, but it should be considered one option among several dietary sources. 8. Beef Liver and Cheese Beef liver and cheese contain small amounts of vitamin D. They also provide other nutrients, but their vitamin D content is generally lower than that of fatty fish. NIH food data lists approximately 42 IU (1 microgram) in a 3-ounce serving of braised beef liver and about 17 IU (0.4 micrograms) in 1.5 ounces of cheddar cheese. The amounts vary with the food and serving size. These foods can contribute to your intake, but they are not as concentrated a source as certain fatty fish. How Much Vitamin
