You may have heard a lot about vitamin D, but do you really know how crucial it is for your health? Without enough of this vitamin, you may struggle with many bodily functions, from supporting bone health to boosting your immune system. If you don’t get enough sunlight or don’t consume foods rich in vitamin D, chances are you may be lacking in this essential nutrient.
So, how to increase vitamin D levels in your body? The good news is there are plenty of natural vitamin D sources available that you can easily include in your diet. In this blog, we’ll explore where vitamin D comes from, what foods are high in vitamin D, and how you can incorporate these foods into your lifestyle.
Before you dive into what foods have vitamin D, let’s start with why this nutrient is essential for your health.
Importance of Vitamin D for Your Health
Let’s dive into the key reasons why vitamin D is vital for your well-being.
Essential for Bone Health and Development
Vitamin D plays a crucial role in keeping your bones strong and healthy. It helps your body absorb calcium and phosphorus, two minerals that are vital for building bone density.
- Vitamin D enhances the absorption of these minerals in your intestines, so your body can effectively use them.
- Without enough vitamin D, your body struggles to maintain the right balance of these minerals, which can lead to weakened bones and an increased risk of fractures.
- It’s especially important for growing children, as they need adequate vitamin D for proper bone development.
Research shows that children with sufficient vitamin D levels have a lower risk of developing conditions like rickets, a disease characterized by soft and weak bones.
Supports Immune and Nervous System Function
Your immune system is your body's defense mechanism which protects you from illnesses and infections. Vitamin D is like a shield that helps strengthen your immune response.
- Studies have shown that adequate vitamin D levels can lower the risk of respiratory infections and other diseases. It supports your body’s ability to fight off pathogens, making it essential for overall health.
- It also plays a vital role in your nervous system. It helps regulate mood and may reduce the risk of mood disorders.
By ensuring you have enough vitamin D, you’re not just taking care of your bones; you’re also supporting your mental well-being.

So, how do you spot a vitamin D deficiency? There are some common symptoms that can tell you if your body lacks vitamin D.
Recognizing Symptoms of Vitamin D Deficiency
Understanding the signs of vitamin D deficiency can be the first step in taking control of your health. Let’s explore some common symptoms you should watch for:
- Fatigue and Low Energy Levels: One of the most common signs of vitamin D deficiency is feeling tired all the time. If you find yourself dragging through the day, lacking motivation, or needing more sleep than usual, it could be due to low vitamin D levels.
- Mood Changes: Vitamin D plays a role in brain health, influencing the production of neurotransmitters that regulate mood. If you’ve noticed changes in your mood or feel more anxious or down than usual, it may be worth checking your vitamin D levels.

You might be thinking how much vitamin D is required daily to prevent a deficiency? Let’s break it down.
Daily Required Intake of Vitamin D
The daily requirement of vitamin D can vary based on several factors, including age, sex, and individual health conditions.
- Infants (0-12 months): 400 IU (International Units) per day
- Children (1-18 years): 600 IU per day
- Adults (19-70 years): 600 IU per day
- Adults (71 years and older): 800 IU per day
- Pregnant and breastfeeding women: 600 IU per day
Factors Influencing Vitamin D Needs
Your individual vitamin D needs can depend on various factors:
- Sun Exposure: Your body produces vitamin D when your skin is exposed to sunlight. If you live in a place with limited sunlight, especially during winter months, you may need to get more vitamin D from food or supplements.
- Skin Tone: Melanin in your skin affects how well you can produce vitamin D from sunlight. Individuals with darker skin may need more sun exposure to produce adequate amounts.
- Diet: Foods filled with vitamin D, such as fatty fish, fortified dairy products, and egg yolks, can help you meet your daily needs. If your diet lacks these foods, you might need to adjust your intake or consider supplements.
- Health Conditions: Certain medical conditions, like obesity or gastrointestinal disorders, can affect how your body absorbs vitamin D, leading to potential deficiencies.
Incorporating good sources of vitamin D into your meals is a great way to make sure you don’t lack this essential vitamin. Let’s see how to increase vitamin D with power-packed foods to help you meet your daily requirements.
Power-Packed Foods for Vitamin D
When it comes to enriching your diet with power-packed sources of vitamin D, certain foods stand out.
Fatty Fish
Fatty fish like salmon, trout, and mackerel are among the richest sources of natural vitamin D.
- Just a single serving of cooked salmon can provide you with around 570 IU of vitamin D.
- These fish are not only tasty but also offer healthy omega-3 fatty acids, which are great for heart health.
Canned Fish
If fresh fish isn’t always an option for you, consider canned fish like sardines and herring. These options are not only affordable and convenient but also rich in vitamin D.
- A 100 gram of canned sardines can provide around 193 IU of vitamin D. Plus, they are easy to add to salads, pasta, or even enjoyed straight from the can.
- Canned fish retains its nutrients, making it an excellent choice for those looking to increase their vitamin D.

Egg Yolks
Egg yolks are another excellent source of vitamin D.
- While one egg yolk contains about 44 IU of vitamin D, it also provides high-quality protein and other essential nutrients.
- Including eggs in your breakfast or as part of your meals can help you incorporate this nutrient into your diet.
Fortified Foods
Many people find it challenging to get enough vitamin D through diet alone, which is where fortified foods come into the picture.
- Breakfast cereals and milk are commonly fortified with vitamin D, making them easy and accessible sources of this nutrient.
- A cup of fortified milk can contain about 120 IU of vitamin D, and many cereals offer similar amounts per serving.
Note: When shopping for cereals, look for those that specifically mention vitamin D on the label.

When it comes to ‘how to increase vitamin D’ with other options, one of the simplest and most effective ways is through sunlight exposure.
Sunlight Exposure
Have you wondered, ‘Where does vitamin D come from?’ Your body has a remarkable ability to produce vitamin D when your skin is exposed to UV (ultraviolet) rays from the sun. Let's explore how this process works and how you can safely enjoy the sun while maximizing your vitamin D levels.
- When your skin comes into contact with UVB rays from the sun, it triggers a chemical reaction that leads to the production of vitamin D.
- Specifically, UVB radiation converts a substance in your skin called 7-dehydrocholesterol into vitamin D3 (cholecalciferol).
- This form of vitamin D is then transformed by your liver and kidneys into its active form.
- Your body uses this to support various functions, such as bone health and immune system support.
Balancing Sun Exposure
Striking the right balance between gaining the benefits of sunlight and protecting yourself from its potential harm is important. Overexposure to the sun can lead to skin damage or cancer. Here are some tips to enjoy the sun safely:
- Limit Exposure: Aim for about 15 to 30 minutes of sun exposure a few times a week, depending on your skin type and the intensity of the sun.
- Apply Sunscreen: Once you've had enough unprotected sun exposure for vitamin D synthesis, apply sunscreen with at least SPF 30 to protect your skin.
- Seek Shade: If you're going to be outside for long periods, take breaks in the shade to avoid overexposure.
- Wear Protective Clothing: Light, breathable clothing can protect your skin from harmful UV rays while still allowing for some sun exposure on your face and arms.
- Know Your Limits: Pay attention to how your skin reacts to sun exposure. If you notice any redness or discomfort, it’s time to cover up or seek shade.
For people living in colder climates or with limited sun exposure, this Reddit thread discusses how people manage normal vitamin D intake without supplements.
When it comes to how to increase vitamin D, food and sunlight are fantastic ways to boost your levels naturally. But what if you're still falling short? That’s where supplementation comes into play.
Supplementation Strategies to Increase Vitamin D
Now, how to increase vitamin D levels in your body through supplementation?
One of the most popular and effective ways to supplement your vitamin D intake is through vitamin D3 (cholecalciferol) supplements. Here are some key points to consider:
- Vitamin D3 Supplements: These supplements are available over-the-counter in various forms, including soft gels, capsules, and gummies. They’re often recommended for individuals who have low levels of vitamin D, especially in regions with limited sunlight.
- Cod Liver Oil: This traditional supplement is rich in natural vitamin D. In addition to boosting your vitamin D levels, cod liver oil provides omega-3 fatty acids, which are known for their heart and brain health benefits. However, it’s important to keep in mind the dosage, as it can also contain high levels of vitamin A, which can be harmful in excess.
Before starting any supplement, it’s wise to consult with a healthcare professional. They can help you determine the right dosage based on your individual needs and health conditions.

Safety Considerations and Potential Side Effects
Here are some safety considerations to keep in mind:
- The daily requirement of vitamin D varies by age, health status, and lifestyle. Generally, adults need about 600 to 800 IU (International Units) of vitamin D per day, but some people may require more based on their specific circumstances.
- Taking too much vitamin D can lead to toxicity, which can cause symptoms such as nausea, vomiting, weakness, and serious complications like kidney damage.
- If you’re taking other medications, be sure to discuss vitamin D supplementation with your healthcare provider. Some medications can interfere with how your body metabolizes vitamin D.
- Regular blood tests can help ensure your vitamin D levels are in the optimal range. This is especially crucial if you’re taking supplements. You should check that you’re maintaining the right balance without risking deficiency or toxicity.
Regular testing can help identify if you’re not getting enough vitamin D, allowing you to adjust your diet, sun exposure, or supplements accordingly. If you’ve started taking supplements, tracking your levels will show whether your efforts are worth it.
Still, some people are more prone to vitamin D deficiency than others, even if they try to eat well or spend time outdoors. Identifying these at-risk groups is important because it helps you understand if you or your loved ones need to pay closer attention to your vitamin D intake.
At-risk Groups for Deficiency
Below, we’ll cover who might be at a higher risk and how to increase vitamin D levels for each group.
Individuals with Limited Sun Exposure
- Indoor Workers: If you spend most of your day inside an office, at home, or in school, your chances of getting adequate sunlight are low.
- Residents in Cold or Cloudy Regions: Living in places with long winters or overcast skies limits your ability to soak in the sun.
- Sunscreen Users: While sunscreen protects your skin, it also blocks UV rays, reducing your body’s ability to produce vitamin D.
People with Darker Skin Tones
Darker skin contains more melanin, a pigment that reduces the skin’s ability to produce vitamin D3 from sunlight. Research shows that people with higher melanin levels often have lower vitamin D levels, especially if they don’t spend enough time outdoors.
Dietary Restrictions or Absorption Issues
- Vegans or Vegetarians: Since many vitamin D3 foods come from animal sources (like fish, eggs, and dairy), plant-based eaters may struggle to get enough vitamin D. Some fortified plant milk and cereals can help close the gap, but additional care is often needed.
- Lactose-Intolerant Individuals: If you avoid dairy due to intolerance, you might miss out on foods containing high vitamin D. In such cases, non-dairy alternatives with added vitamin D, such as fortified almond or soy milk, can be helpful.
- Malabsorption Conditions: People with conditions like Crohn’s disease, celiac disease, or chronic liver disorders may struggle to absorb vitamins efficiently. This makes it harder to meet the daily requirement of vitamin D, even with a balanced diet.
Final Thoughts
In conclusion, how to increase vitamin D? It primarily comes from two sources: food and sunlight. Start by including foods strong in vitamin D—like salmon, egg yolks, and fortified milk—into your daily routine. Pairing these vitamin D3 foods with moderate sun exposure ensures that your body can maintain healthy levels naturally.
If you live in areas with limited sunlight or follow a diet that restricts foods containing high vitamin D, supplements are a practical option. Taking vitamin D3 (the most effective form) or cod liver oil can fill in any gaps.
Although a balanced mix of food, sunshine, and supplements can work wonders, it’s important to consult your healthcare provider for personalized advice. They can help monitor your levels and recommend specific doses if needed.
