21 Best High-Vitamin D Foods: Natural & Fortified Sources to Boost Your Levels
A balanced mix of natural and fortified foods makes hitting your vitamin D target simple.
Vitamin D is an essential fat-soluble nutrient with a pivotal role in the body’s bone, immune, and heart health. With few foods containing it naturally and limited sunlight exposure in many climates, understanding the best dietary sources is key for optimal wellness. This guide outlines the top foods high in vitamin D, explains its importance, and covers practical strategies for hitting recommended levels.
Why Vitamin D Matters for Your Health
Vitamin D is involved in several crucial body functions:
- Enhances calcium absorption for stronger bones and teeth
- Supports immune system function and helps reduce inflammation
- Plays a role in muscle health and nerve signaling
- Linked to lower risk of chronic diseases like osteoporosis and heart conditions
Deficiency can lead to rickets in children, increase the risk of bone fractures in adults, and contribute to fatigue, muscle weakness, and poor immunity.
How Much Vitamin D Do You Need?
The recommended dietary allowance (RDA) for vitamin D varies by age and life stage:
| Age Group | RDA Vitamin D (IU) | RDA Vitamin D (mcg) |
|---|---|---|
| Birth to 12 months | 400 IU | 10 mcg |
| 1-70 years | 600 IU | 15 mcg |
| 71+ years | 800 IU | 20 mcg |
| Pregnancy/Breastfeeding | 600 IU | 15 mcg |
While the body can produce vitamin D via sunlight, factors such as climate, skin tone, sunscreen use, and time spent indoors affect natural synthesis. Experts recommend getting most of your vitamin D through foods and supplements—especially in the winter or if you have limited sun exposure.
The Best Natural Food Sources of Vitamin D
Very few foods naturally contain vitamin D, but incorporating the following options can help you achieve optimal levels:
1. Fatty Fish
- Salmon: Wild-caught is best, with 556–924 IU (70–116% DV) per 3.5 oz serving. Farmed salmon averages 441 IU (55% DV).
- Mackerel: 643 IU per 3.5 oz (100g)—an excellent source.
- Swordfish: 566 IU per 3 oz cooked serving.
- Tuna: Canned light tuna offers 269 IU (34% DV) per 3.5 oz serving; fresh cooked tuna provides about 156 IU per 3 oz.
- Halibut: 190 IU per 3.5 oz (100g).
- Sardines (Fresh and canned): 167-193 IU per 3.5 oz (20-24% DV).
- Herring: 167 IU per 3.5 oz; pickled herring offers 113 IU, but is high in sodium.
Tip: Fatty fish are among the richest natural sources—aim for two servings per week for maximum benefit.

2. Cod Liver Oil
A classic supplement, cod liver oil provides about 1,360 IU (34 mcg) per tablespoon—over 200% of your daily need. However, it’s high in vitamin A, so moderation is crucial (less than 1 tsp per day is generally advised for adults).
3. Egg Yolks
Egg yolks have about 40–50 IU of vitamin D each, depending on the hen’s diet and sun exposure. Eggs from pasture-raised chickens or those given vitamin D-enriched feed can offer even more per yolk. While a few eggs won’t satisfy the full daily requirement, they’re a helpful addition for variety.
4. Mushrooms
Some mushrooms are unique in that they can make vitamin D when exposed to sunlight or ultraviolet (UV) light. Varieties and content include:
- UV-exposed maitake mushrooms: Over 2,000 IU per 3 oz serving (over 250% DV).
- Portobello (UV-treated): Can deliver 400-700 IU per cup, sliced and cooked.
- Wild mushrooms: More variable; cultivated mushrooms are usually low in vitamin D unless UV-exposed.
Check for packaging that states “UV-exposed” or “high in vitamin D.” Normal white or cremini mushrooms grown in darkness don’t provide significant amounts.
5. Beef Liver
Provides about 42 IU per 3 oz cooked serving. While not a large amount, it also packs iron and vitamin A, making beef liver a nutrient-dense choice to include occasionally.
Best Fortified Foods for Vitamin D
Since most plant-based or low-fat foods are poor natural sources of vitamin D, food fortification bridges the gap. Common fortified foods include:
- Cow’s Milk: Almost all cow’s milk in the U.S. is fortified, usually with about 120 IU per 8 oz (15% DV).
- Plant-Based Milks: Soy, almond, and oat milks are often fortified, providing 100-140 IU per cup. Always check the nutrition label.
- Breakfast Cereals: Fortified cereals offer around 80 IU per serving. Choose whole-grain, low-sugar varieties.
- Orange Juice: Fortified versions contain about 100 IU per 8 oz (15% DV).
- Yogurt: Certain brands fortify their yogurt with about 116 IU per cup.
- Tofu: Some packaged tofu is fortified and may provide up to 140 IU per serving. Not all tofu is fortified, so checking the label is important.
- Cheese: Some processed cheeses are fortified, but the amount varies widely.
Pro tip: Double-check labels, as vitamin D content can vary even within the same product type.
Additional Tips for Maximizing Vitamin D Intake
- Prioritize variety: Rely on a mix of natural and fortified foods rather than a single food source.
- Safe sun exposure: When possible, brief periods of sunlight (5–30 minutes, 2–3 times a week) can help—preferably with skin protection to avoid burn and cancer risk.
- Consider supplements: If you have limited dietary options (e.g., vegan, lactose-intolerant, or low seafood intake), a multivitamin or dedicated vitamin D supplement may be recommended, especially for older adults.
Signs of Vitamin D Deficiency
- Fatigue and general tiredness
- Weak or aching muscles
- Bone or back pain
- Mood changes, including depression
- Impaired wound healing
- Frequent infections or weakened immunity
If you experience these symptoms or belong to higher-risk groups (older adults, people with darker skin, little sun exposure, restrictive diets), speak with a healthcare professional about checking your vitamin D status.

Special Considerations: Who is Most at Risk for Low Vitamin D?
- Older adults (age 65+), due to decreased skin synthesis and dietary intake
- People with darker skin, as melanin reduces natural production from sunlight
- Those with limited sun exposure (indoor lifestyles, northern climates, sunscreen use)
- Vegans and strict vegetarians not consuming fortified products or fish
- People with certain digestive or kidney conditions affecting absorption or activation of vitamin D
- Infants who are exclusively breastfed and not given a supplement
Frequently Asked Questions (FAQs)
What are the top three food sources of vitamin D?
The best natural sources are fatty fish (like salmon and mackerel), cod liver oil, and UV-exposed mushrooms. Fortified cow’s milk and plant-based beverages are also top contributors for many people.
Can you get enough vitamin D from food alone?
For many people, it is difficult to achieve optimal vitamin D intake through food alone, especially if you avoid fortified foods or fish. Supplements or brief sun exposure are sometimes necessary to reach recommended levels.
Are eggs a good source of vitamin D?
Egg yolks provide small but helpful amounts. For those who eat several eggs a week, they can contribute meaningfully, especially if the eggs are from pasture-raised or vitamin D-enriched hens.
What’s the difference between vitamin D2 and D3?
Vitamin D2 (ergocalciferol) is mostly found in plant sources (some fungi/mushrooms), while vitamin D3 (cholecalciferol) is found in animal-based foods (fish, eggs) and is more efficiently absorbed and utilized by the body.
Should you worry about vitamin D toxicity?
Toxicity is rare from food or sun, but can occur with excessive supplement use (above 4,000 IU per day long-term). Always consult with a healthcare provider before taking high-dose vitamin D supplements.
How do I know if my foods are fortified with vitamin D?
Check the nutrition facts label. It will list vitamin D content per serving, as a percentage of daily value (%DV) and usually in micrograms (mcg) or International Units (IU). Not all brands of milk, yogurt, or plant-based alternatives are fortified, so review labels carefully.
Expert Tips for Meeting Your Daily Vitamin D Needs
- Incorporate fatty fish, eggs, and vitamin D-fortified products into your regular meal planning.
- If following a vegetarian or vegan diet, prioritize UV-exposed mushrooms, fortified soy or almond milk, cereals, and tofu.
- Consider low-dose supplements in consultation with your healthcare provider, especially during winter or if you are in a risk group.
Key Takeaway
Vitamin D is essential for your long-term health and immunity. Because very few foods naturally provide adequate amounts, a balanced approach using fish, eggs, fortified foods, and—when appropriate—supplements is the most reliable way to meet your needs and support overall wellness.
