Vitamin D is an essential nutrient that assists in the absorption of calcium and maintains healthy bones and muscles in the body. Deficiency of this vitamin can lead to fatigue, muscle weakness, or bone-related complications. Dietary intake and sunlight exposure are helpful in increasing the level of vitamin D, but in case of vitamin D deficiency, supplementation under medical guidance is recommended.
5 Key Takeaways
- Vitamin D is required for maintaining strong bones, muscles, and teeth.
- Amongst all natural foods containing vitamin D, fatty fish are at the top.
- Eggs and other fortified products are also sources of vitamin D.
- Sunlight is an effective way to get vitamin D in the body.
- Deficiency might require supplement consumption along with diet changes.
What Is Vitamin D and Why Does Your Body Need It?
Vitamin D is one of the fat-soluble vitamins that help the body absorb calcium from food sources. The combination of both substances helps maintain strong bones.
Apart from the role in bone formation, vitamin D plays a part in proper muscle function and the immune system. You can build strong immunity naturally by combining key nutrients with a healthy diet. It can be produced by the body itself when the skin comes into contact with sunlight and through certain foods.
A person’s requirement of vitamin D depends on various factors such as age, among others. An adult’s daily intake is set at 600 IU (15 mcg), whereas adults older than 70 years should consume 800 IU (20 mcg) daily. (ods.od.nih.gov)
What Causes Vitamin D Deficiency?
There are various causes of vitamin D deficiency. A basic cause would be the lack of vitamin D in food and sunlight. However, there are other causes as well.
Individuals who mostly stay indoors will get less exposure to sunlight. Individuals with dark skin may also have low vitamin D synthesis from the same amount of sunlight due to a reduction in the skin’s ability to synthesize vitamin D as a result of melanin production.
Age can be another factor since older skin does not synthesize as much vitamin D. Medical conditions that interfere with fat absorption also affect vitamin D absorption. (ods.od.nih.gov)
So, simply eating more vitamin D foods may not solve the problem if there is another reason for the deficiency.
Vitamin D Deficiency Symptoms You Should Know
There may be signs of bone pain and muscle weakness when the deficiency worsens. When children suffer from vitamin D deficiency, it could result in rickets, and osteomalacia in adults. Other individuals will experience fatigue or body pain, but such symptoms are also caused by various other factors—often leading to questions on why body feel weak and tired. Therefore, don’t jump to the conclusion that fatigue indicates a deficiency in vitamin D.
Best Vitamin D Rich Foods
Now comes the most useful part.
There are not many foods that naturally contain large amounts of vitamin D. This is why it can be useful to include a mix of naturally rich foods and fortified foods.
1. Fatty Fish
Fatty fish are some of the best natural food sources of vitamin D.
Good choices include:
- Salmon
- Trout
- Sardines
- Tuna
- Mackerel
The exact amount of vitamin D can vary depending on the fish and how it is prepared. Many of these option are also notable omega 3 foods for heart health.
If you eat non-vegetarian food, adding fatty fish to your meals can be a simple way to increase vitamin D intake.
2. Egg Yolks
Egg yolks contain vitamin D, although the amount is much smaller than what you may get from fatty fish.
You can include eggs as part of a balanced diet, especially if you also need a good source of protein, given the many benefits of eating boiled eggs.
There is no need to eat huge numbers of eggs just to increase vitamin D.
3. Fortified Milk
Some milk is fortified with vitamin D. This means vitamin D has been added during processing.
Check the nutrition label because not every milk product contains added vitamin D.
Fortified milk can be a useful option for people who do not eat fish.
4. Fortified Plant Milk
Some soy, almond, oat, and other plant-based milks may also have vitamin D added to them.
Again, check the label because the amount can be very different between products.
Choose an unsweetened option if you are also trying to reduce added sugar.
5. Fortified Breakfast Cereals
Some breakfast cereals have vitamin D added to them.
Look at the nutrition label before buying one. A cereal can be fortified with vitamin D but still contain a lot of added sugar, so the overall nutrition matters too.
6. Mushrooms
Some mushrooms contain vitamin D, especially mushrooms that have been exposed to ultraviolet light.
However, the amount can vary a lot between different mushrooms and products. Be sure to follow proper food preparation safety when cleaning mushrooms.
They can still be a useful part of a balanced diet.
Vitamin D Rich Foods for Vegetarians
If you are vegetarian, getting vitamin D only from natural foods can be a little difficult because there are fewer naturally rich plant-based sources. Explore other valuable options when looking for protein for vegetarians.
You can include vitamin D-fortified foods such as fortified milk or plant-based milk and some fortified cereals. UV-exposed mushrooms can also provide vitamin D.
For vegetarians who have a confirmed deficiency, food alone may not provide enough vitamin D. A doctor may recommend a supplement depending on the blood test and the person’s needs.
This is why there is no need to follow a very restrictive diet just to get vitamin D.
How to Increase Vitamin D Naturally?
Food is only one part of the answer.
Your skin can make vitamin D when it is exposed to sunlight. However, the amount your body makes depends on several things, including skin colour, age, location, time of day, season, clothing, and sunscreen use. (ods.od.nih.gov)
This means there is no single sunlight rule that works for everyone.
Also, you should not deliberately stay in the sun for long periods without protection just to increase vitamin D. Too much UV exposure increases the risk of skin cancer.
A better approach is to get sensible sunlight exposure while protecting your skin from excessive UV exposure.
Can You Cure Vitamin D Deficiency Naturally?
This depends on how low your vitamin D level is and why it became low. If your vitamin D level is only slightly low, improving your diet, getting appropriate sunlight, and following your doctor’s advice may help. But if you have a significant deficiency, food and sunlight may not be enough.
Doctors may recommend vitamin D supplements to bring levels back to a healthy range. The amount needed can vary, so taking very high doses on your own is not a good idea. Too much vitamin D can cause calcium levels in the blood to become too high, which can lead to problems such as nausea, weakness, confusion, and kidney stones. You can read more about the signs of too much vitamin d to stay safe. So “natural” does not always mean “better” when treating a confirmed deficiency.
A Simple Vitamin D Diet Chart
Here is an easy example of how you can include vitamin D sources in your normal diet.
| Meal | Example |
|---|---|
| Breakfast | Fortified milk + oats/whole-grain cereal + egg |
| Mid-morning | Fruit + a few nuts |
| Lunch | Roti/rice + dal + vegetables + curd |
| Evening | Fortified milk or another fortified food |
| Dinner | Grilled fish + vegetables, or paneer/tofu with vegetables |
| Optional | UV-exposed mushrooms added to a meal |
This is only an example, not a treatment plan for vitamin D deficiency.
If you are vegetarian, you can choose fortified foods and mushrooms instead of fish.
Can Vitamin D Help With Tiredness?
Low vitamin D can result in conditions such as fatigue and weak bones in cases of serious deficiency. However, there are several reasons for fatigue. You can learn more about brain fog vitamin deficiency connections as well.
Fatigue can occur due to lack of proper sleep, stress, anemia, thyroid dysfunction, infection, or inadequate nutrition. This means that if you are experiencing fatigue all the time, do not jump to the conclusion that your problem is low vitamin D. A medical professional can help you discover the exact cause.
Does Vitamin D Help With Weight Loss?
Vitamin D is essential for overall well-being; however, taking more vitamin D is not an effective solution for losing weight.
If you lack this vitamin, it is essential to compensate for its deficiency. However, it doesn’t mean that the intake of vitamin D will cause weight loss for sure.
Weight management implies proper nutrition, exercise, healthy sleep, and adequate consumption of calories.
Do not purchase large amounts of vitamin D supplements because of weight loss claims on packaging.

When Should You Get Your Vitamin D Checked?
If you experience symptoms that may indicate a lack of vitamin D, you should seek the opinion of a doctor. People who are at a higher risk of being deficient can also consider getting professional help.
A blood test can determine your vitamin D level when required by a healthcare professional. You should not take a mega dose of vitamin D because of fatigue and body aches.
Final Thoughts
Vitamin D plays an essential role in proper bone strength, muscle functioning, and body processes. The consumption of various types of food, such as oily fish, eggs, fortified milk, fortified plant milk, and UV-exposed mushrooms, will help you receive enough vitamin D with your diet. The other source of vitamin D that can provide your body with it is sun exposure; however, you do not have to spend too much time outdoors unprotected.
When you think about ways to boost your levels of vitamin D, you should focus on your diet and the appropriate sun exposure. Should the test results show your real deficiency in the vitamin, you may need to take some supplements. The key point here is not to consume a large amount of the substance yourself; rather, it is vital to use an appropriate amount.
