What is Vitamin D?
Vitamin D is a fat-soluble vitamin that plays a crucial role in calcium absorption, bone health, immune function, and overall well-being. It is unique because our bodies can produce it when exposed to sunlight. However, dietary sources and supplements are often needed to maintain optimal levels, especially for those with limited sun exposure.
What Does Vitamin D Do?
Vitamin D performs several critical functions in the body, including calcium absorption, regulation of phosphate levels, support of immune function, maintenance of muscle function, and regulation of cell growth.
- Calcium Absorption: One of vitamin D's primary roles is to enhance the absorption of calcium in the intestines, ensuring that your bones and teeth receive the necessary nutrients to stay healthy. Pairing vitamin D3 with K2 can further support this process by helping direct that absorbed calcium toward your bones rather than soft tissue.
- Regulates Phosphate Levels: Vitamin D helps regulate blood phosphate levels, which are important for bone formation and energy levels.
- Supports Immune Function: Vitamin D activates and regulates immune cells, helping the body respond effectively to pathogens and reducing inflammation.
- Maintains Muscle Function: Vitamin D supports muscle strength and function, reducing the risk of falls and injuries, particularly among older adults.
- Modulates Cell Growth: Vitamin D plays a role in cell growth, differentiation, and apoptosis, which is crucial for maintaining healthy tissues and preventing abnormal cell growth.
Understanding what vitamin D is good for and what it does can help highlight its importance in your daily routine.
Benefits of Vitamin D
Vitamin D has numerous benefits, including supporting bone health, immune function, cardiovascular health, mental health, and overall well-being.
- Bone Health: Vitamin D enhances calcium absorption, supporting bone density and reducing the risk of fractures and osteoporosis.
- Immune Function: It boosts the immune system by supporting the production and activity of immune cells, helping to fend off infections and maintain immune balance.
- Cardiovascular Health: Adequate vitamin D levels are linked to a lower risk of cardiovascular diseases, as it helps regulate blood pressure and heart function.
- Mental Health: Vitamin D influences mood regulation by aiding in the production of serotonin, reducing the risk of depression and mood disorders.
- Overall Well-being: Vitamin D supports various bodily functions, including muscle function and inflammatory response, contributing to overall health.
Incorporating vitamin D foods such as fatty fish, egg yolks, and fortified products into your diet, along with sensible sun exposure, can help maintain optimal levels. For those unable to get enough from diet and sunlight, supplements can be beneficial.
What are the different types of vitamin D?
Vitamin D comes in two forms, D2 and D3, which we'll break down below.
Vitamin D2
Vitamin D2 (ergocalciferol) is the plant-based form of vitamin D, found naturally in UV-exposed mushrooms and used to fortify foods like plant milks and cereals.
Unlike vitamin D3, which comes from animal sources and sunlight, D2 is synthesized by plants and fungi when exposed to ultraviolet light.
Your body can use D2 to raise vitamin D levels, but research shows it's less effective than D3 at raising and maintaining blood levels over time. For that reason, D2 is most commonly found in vegan and vegetarian supplements and fortified foods, rather than occurring naturally in a wide range of foods.
Vitamin D3
Vitamin D3 (cholecalciferol) is the animal-based form of vitamin D, found naturally in fatty fish, egg yolks, and cod liver oil, and produced in your skin when exposed to sunlight.
Unlike vitamin D2, which comes from plants and fungi, D3 is synthesized in the body itself or obtained from animal sources and fortified foods.
Your body uses D3 more efficiently than D2, raising and maintaining blood levels of vitamin D more effectively over time. For that reason, D3 is the form most commonly used in fortified foods and general-purpose supplements, and it's generally considered the preferred source when it's available.
Vitamin D2 vs. Vitamin D3: What's the Difference?
The main difference between vitamin D2 and vitamin D3 is their source and how effectively your body uses them.
Vitamin D2 comes from plants and fungi, while vitamin D3 comes from animal products and fortified foods, and raises blood levels more efficiently. Vitamin D2 shows up mainly in UV-exposed mushrooms and fortified plant milks and cereals, while vitamin D3 is found in fatty fish, egg yolks, cod liver oil, and fortified dairy.
Because vitamin D3 is absorbed more efficiently and stays active in the body longer, it's generally considered the more effective form for maintaining healthy vitamin D levels, which is why vegans and vegetarians relying on D2-fortified foods often need higher intakes or a vitamin D3 supplement to reach the same result.
The table below highlights the differences between Vitamin D2 vs. D3.
| Feature | Vitamin D2 (Ergocalciferol) | Vitamin D3 (Cholecalciferol) |
|---|---|---|
| Source Type | Plant-based | Animal-based & Sunlight |
| Food Sources | Mushrooms (UV-exposed), Fortified plant-based milk & cereals | Fatty fish, Egg yolks, Cod liver oil, Fortified dairy |
| Absorption Rate | Lower | Higher |
| Effectiveness | Less potent, shorter lifespan in the body | More effective in raising blood levels of Vitamin D |
| Best For | Vegetarians & vegans | Most effective for overall Vitamin D needs |
Vitamin D3 Foods: Which Foods Contain D3?
The main vitamin D3 foods are fatty fish (salmon, trout, sardines, canned tuna), cod liver oil, egg yolks, and beef liver, since D3 is the form animals produce. Fortified milk is also commonly made with D3. The picture is less clear for other fortified foods: plant milks, tofu, cereal, and orange juice may use D2 or D3 depending on the brand, so check the label. UV-exposed mushrooms provide mainly D2. For exact IU amounts per serving, see the full list of the 15 best vitamin D foods below.
The Role of Sunlight in Vitamin D Production
Sunlight is an excellent natural source of Vitamin D3. When UVB rays from sunlight penetrate the skin, a chemical reaction occurs, converting a precursor molecule into Vitamin D3. However, several factors can influence the body's ability to produce Vitamin D3 from sunlight, including skin pigmentation, time of day, latitude, and sunscreen use. Therefore, spending a brief amount of time outdoors without sunscreen is recommended to allow the skin to produce Vitamin D3 naturally.
Vitamin D Deficiency: Causes and Symptoms
Vitamin D plays a crucial role in maintaining your health, from supporting bone strength to enhancing immune function. When you don't get enough Vitamin D, it can lead to a range of health issues. Understanding the causes and symptoms of Vitamin D deficiency can help you address this common problem effectively.
Vitamin D Deficiency Causes
Vitamin D deficiency arises primarily from limited sun exposure, insufficient dietary intake, and factors such as skin pigmentation and age-related changes that reduce the body's ability to synthesize and absorb vitamin D. Individuals living in high latitudes, those with darker skin, and older adults are particularly at risk. Additionally, certain medical conditions can impair Vitamin D metabolism, further contributing to deficiency.
- Limited Sun Exposure: Since Vitamin D is synthesized in the skin upon exposure to sunlight, inadequate sun exposure is a major cause of deficiency. People living in areas with long winters, high latitudes, or those who spend most of their time indoors are at higher risk.
- Dietary Insufficiency: Relying solely on dietary sources for Vitamin D can be challenging. Foods rich in Vitamin D, such as fatty fish, egg yolks, and fortified products, may not always be consumed in sufficient quantities to meet daily requirements.
- Skin Pigmentation: Individuals with darker skin have higher melanin levels, which can reduce the skin's ability to produce Vitamin D from sunlight. This can increase the risk of deficiency, particularly in regions with limited sunlight.
- Age-Related Factors: As people age, their skin becomes less efficient at synthesizing Vitamin D. Additionally, older adults often have reduced dietary intake and vitamin D absorption, increasing their risk of deficiency.
- Medical Conditions: Certain medical conditions, such as gastrointestinal disorders (e.g., Crohn’s disease, celiac disease) and chronic kidney disease, can impair Vitamin D absorption and metabolism, leading to deficiency.
Symptoms of Vitamin D Deficiency
- Bone Pain and Weakness: One of the most common symptoms of Vitamin D deficiency is bone pain and muscle weakness. Deficiency can lead to conditions such as osteomalacia in adults and rickets in children, both of which are characterized by weakened bones.
- Fatigue and Weakness: Low Vitamin D levels can lead to general fatigue, weakness, and reduced energy, affecting overall quality of life.
- Mood Changes: Vitamin D deficiency has been linked to mood disorders, including depression and seasonal affective disorder (SAD). This nutrient plays a role in regulating neurotransmitters and stabilizing mood.
- Frequent Infections: A compromised immune system due to insufficient Vitamin D can lead to frequent infections, particularly respiratory illnesses.
- Hair Loss: In some cases, Vitamin D deficiency can contribute to hair loss or thinning, as this vitamin plays a role in the health of hair follicles.
Addressing Vitamin D deficiency involves increasing sun exposure, consuming Vitamin D rich foods, and considering supplements if necessary. Monitoring your Vitamin D levels and consulting with a healthcare provider can help you effectively manage and prevent Vitamin D deficiency.

Because vitamin D occurs naturally in so few foods, most people end up meeting their needs through a mix of these sources rather than any single food alone.
Regularly eating the vitamin D-rich foods listed above is a strong foundation, but how much of that vitamin D your body actually uses depends on more than just what's on your plate. Because vitamin D is fat-soluble, factors like timing, pairing with dietary fat, and even which nutrients you take alongside it can significantly change how much you absorb. If you want to get the most out of every source on this list, here's how to maximize your vitamin D absorption.
Vitamin D Foods for Vegetarians
Most natural sources of vitamin D are found in animal-based foods, which presents a significant challenge for vegans. If you follow a plant-based diet, you likely already know the difficulties of getting enough vitamin D through your diet. Discover how to get enough Vitamin D on a plant-based diet to maintain optimal vitamin D levels as a vegetarian or vegan.
Do Fruits and Vegetables Have Vitamin D?
Despite how often people search for vitamin D fruits or vitamin D vegetables, produce isn't a meaningful source of this nutrient. The one exception is mushrooms exposed to UV light, which convert a plant compound into usable vitamin D. Foods like spinach, carrots, oranges, and bananas are excellent sources of other nutrients, but they won't move the needle on vitamin D unless they're fortified. If you're building a vitamin D-rich diet from plants, look to fortified plant milks, cereals, and tofu instead of fresh produce.
