Key Takeaways
- People can get vitamin D from sunlight, food, and supplements.
- Food sources of vitamin D include fatty fish, egg yolks, and mushrooms.
- Certain foods, like cow’s milk, non-dairy milk, breakfast cereals, and orange juice, are also frequently fortified with vitamin D.
Healthy foods that are rich in vitamin D include fatty fish, mushrooms grown under ultraviolet (UV) light, and egg yolks, among others. Some foods, such as milk and breakfast cereal, are often fortified with vitamin D—meaning that it is added to them during manufacturing.
Fatty Fish

Oily, fatty fish, which also provide omega-3 fatty acids, are one of the best food sources of vitamin D. Examples of fish proteins that are rich in vitamin D include:
- Herring
- Salmon
- Mackerel
- Tuna
- Sardines
- Trout
- Swordfish
Mushrooms Grown Under UV Light

Mushrooms produce vitamin D if exposed to UV radiation during growth. Raw shiitake, chanterelle, and oyster mushrooms are particularly rich sources of vitamin D if grown in this way.
Cooking mushrooms in water doesn’t affect the amount of vitamin D content, but cooking mushrooms in fats like oil may reduce vitamin D content.
Eggs

Egg yolks provide another common source of vitamin D. The vitamin D content of eggs may be increased naturally by adding vitamin D to a hen’s diet or exposing egg yolks to UVB rays. Hens that are pasture-raised, and therefore exposed to more sunlight, also produce eggs with more vitamin D.
Vitamin D-Fortified Foods

Dairy products and other foods are often fortified with vitamin D. However, this is not always the case. Check the ingredient panel to see if vitamin D is listed for these typically fortified foods:
- Cow’s milk
- Soy milk
- Almond milk
- Oat milk
- Cheese
- Yogurt
- Breakfast cereals
- Orange juice
- Margarine
Many foods are fortified with vitamin D because relatively few foods naturally contain high amounts of it. Some clinicians argue that this is beneficial in preventing vitamin D deficiency and increasing the vitamin D intake in the general population, particularly among people with food allergies and those who follow vegan or vegetarian diets.

How Much Vitamin D Should You Get Daily?
Vitamin D is an essential micronutrient that helps your body absorb calcium, protects the health of your bones and teeth, reduces inflammation, regulates blood sugar, and boosts your immune response. While your body can produce vitamin D with exposure to sunlight, this can also increase the risk of skin cancer. That’s why foods rich in vitamin D are an important part of a healthy diet.
According to the U.S. Food and Drug Administration (FDA), the recommended daily intake of vitamin D is as follows (listed in both International Units and micrograms):
- 0-12 months old: 10 mcg/400 IU
- 1-13 years old: 15 mcg/600 IU
- 14-18 years old: 15 mcg/600 IU
- 19-70 years old: 15 mcg/600 IU
- 71+ years old: 20 mcg/800 IU
- Pregnant or breastfeeding: 15 mcg/600 IU
When to Take Vitamin D Supplements
Our bodies produce vitamin D in response to ultraviolet (UV) radiation from the sun. But in the U.S., many people don’t get enough vitamin D from sunlight, particularly because excessive amounts can lead to skin cancer.
If you think you may be at risk for vitamin D deficiency, your healthcare provider may recommend that you take a daily vitamin D supplement to lower your risk.
Vitamin D Supplements
If you are at risk for vitamin D deficiency, vitamin D supplements may help to prevent any complications. Risk factors for vitamin D deficiency include:
- Spending a lot of time indoors
- Living in a cold climate
- Having dark skin
- Being 65 years old or older
- Eating a plant-based diet, such as a vegan or vegetarian diet
- Allergies to foods that typically contain vitamin D
- Having had gastric bypass surgery
- Chronic kidney or liver disease
- Crohn’s disease
- Ulcerative colitis
- Celiac disease
- Taking certain medications, such as anti-seizure and cholesterol-lowering medications
Am I Getting Enough Vitamin D From My Diet?
If left untreated, a deficiency in vitamin D can lead to a number of health complications. These include:
- Rickets, a disorder that causes bone deformities in children
- Osteoporosis, a condition caused by bone loss and reduced bone density
- Osteomalacia, a “bone softening” disorder that primarily affects adults
- Muscle spasms
Vitamin D deficiency typically doesn’t cause many symptoms at first. The main way to tell if you have a vitamin D deficiency is through a blood test from your healthcare provider.
Can You Get Too Much Vitamin D?
Some researchers have argued that eating fortified foods may lead to excessive vitamin D intake, known as vitamin D toxicity.
Signs of vitamin D toxicity include:
- Dehydration
- Vomiting
- Reduced appetite
- Fatigue
- Confusion
- Frequent urination
- Constipation
- Muscle weakness
Consuming too much vitamin D may also lead to hypercalcemia (very high levels of calcium in the blood). Over time, hypercalcemia may lead to complications such as:
- Kidney failure
- Disorientation
- Arrhythmia (irregular heartbeat)
