Up to 42% of people in the U.S. are deficient in vitamin D, with the percentage rising significantly for those with darker skin. Although sunlight naturally triggers vitamin D production, many still do not reach the recommended daily intake of 400–800 IU. Adding foods high in vitamin D to your meals is an effective, sustainable way to improve your levels.
Besides spending more time outdoors, dietary choices are a practical method to enhance vitamin D intake. While only a few foods naturally contain vitamin D, many are fortified to help meet daily requirements. Even vegetarians and vegans have several fortified options.
Vitamin D is crucial for multiple aspects of health: it supports the immune system, aids calcium absorption for strong bones, enhances brain function, stabilizes mood, and can contribute to weight management. Ensuring adequate intake helps maintain energy and overall wellness.
Top 10 Foods to Boost Vitamin D
1. Fortified Tofu
Fortified tofu is an excellent vegan source of vitamin D. Modern brands enrich it with bioavailable D2 or D3 from algae, making it easier to meet daily requirements.
2. Fatty Fish: Rich in Vitamin D and Omega-3
Fatty fish provide both vitamin D and essential omega-3 fatty acids. Wild-caught salmon is highly recommended for its nutrient content, but bluefish and catfish are also good choices. One serving often covers your daily vitamin D needs. Cooking methods and sourcing can influence the amount of vitamin D retained.
More budget-friendly options include sardines, herring, and canned tuna (consume tuna no more than once a week). Oysters and shrimp offer additional variety.
3. Eggs
Vitamin D is concentrated in the yolk. One egg typically provides around 50 IU of vitamin D. Eggs from hens fed vitamin-enriched diets can contain 200–8,000 IU, depending on fortification.
4. Cod Liver Oil
Cod liver oil is a traditional and potent source of vitamin D, vitamin A, and omega-3s. Capsules are convenient, but avoid excessive intake because of vitamin A content.
5. Fortified Milk and Plant-Based Alternatives
Milk has long been fortified to prevent rickets, with one cup providing roughly half of a child’s daily vitamin D requirement. Yogurt often retains similar levels. Vegans can choose fortified almond, soy, or rice milk to meet daily needs. Outdoor activity also supports natural vitamin D production.
6. Mushrooms
Certain mushrooms exposed to UV light convert it into vitamin D, similar to how humans produce it from sunlight. UV-treated mushrooms are the most reliable source among plant foods.
7. Fortified Orange Juice
Fortified orange juice provides a plant-based source of vitamin D, typically offering around 100 IU per serving. Check labels to ensure the juice is fortified.
8. Beef or Calf Liver
Liver contains vitamin D, roughly 50 IU per serving. It is nutrient-dense but should be consumed in moderation due to high vitamin A levels, which can be toxic in excess.
9. Caviar
A tablespoon of caviar provides approximately 20 IU of vitamin D. It’s nutrient-rich but should be eaten in moderation due to fat and calorie content.
10. Fortified Cereal
Fortified cereals are a convenient way to boost vitamin D. Choose whole-grain, low-sugar options and check labels carefully—fortification alone does not guarantee a healthy cereal.
Conclusion
Many Americans need to increase vitamin D through diet, supplementation, or more sun exposure. Persistent fatigue, low immunity, or joint pain may indicate deficiency, which a blood test can confirm. Maintaining a balanced diet and consulting a nutritionist can help ensure you get sufficient nutrients for a healthy, active lifestyle.
