Vitamin D is one of the essential vitamins for the proper functioning of our body.

It not only contributes to the health of bones and teeth but also plays a crucial role in maintaining the immune system and regulating the absorption of calcium and phosphorus.

What is Vitamin D and Why is it Important

Vitamin D is a fat-soluble vitamin that the body can obtain in two ways: through diet and through exposure to the sun.

When the skin is exposed to UVB rays from the sun, the body synthesizes vitamin D.

However, it is not always possible to get a sufficient amount of vitamin D from the sun alone, especially during the winter months or in areas with little sunlight.

The unit of measurement for vitamin D is IU, where 1 IU corresponds to 0.025 µg of vitamin D.

Benefits of Vitamin D

Bone and Teeth Health: Vitamin D is crucial for the absorption of calcium, essential for the formation and maintenance of healthy bones and teeth.

A deficiency of this important vitamin can lead to osteoporosis in adults and rickets in children.

Immune System Function: Vitamin D helps modulate the immune response, contributing to the prevention of infections and autoimmune diseases.

Muscle Health: Vitamin D is involved in muscle function, and a deficiency can lead to muscle weakness and pain.

Mood Regulation: Studies suggest that adequate levels of vitamin D can help prevent mood disorders such as depression.

How to Increase Vitamin D Intake Through Diet: Foods Rich in Vitamin D

Integrating vitamin D through diet is essential, especially when sun exposure is limited.

Here is a list of foods rich in vitamin D that you should consider including in your diet:

  1. Fatty Fish
    Fatty fish are one of the best sources of vitamin D. Among the richest are:
    Salmon - Not only is it an excellent source of protein and omega-3 fatty acids, salmon is also very rich in vitamin D.
    A 100-gram serving of salmon can contain between 361 and 685 IU of vitamin D.
    Mackerel - Another fatty fish rich in vitamin D is mackerel.
    A 100-gram serving can provide about 360 IU of vitamin D.
    Tuna - Canned tuna is a practical and affordable option.
    A 100-gram serving of canned tuna contains about 236 IU of vitamin D.
     
  2. Cod Liver Oil
    Cod liver oil is known for its high content of vitamin D and omega-3 fatty acids.
    Just one teaspoon of cod liver oil can provide about 450 IU of vitamin D, covering much of the daily requirement.
     
  3. Mushrooms
    Mushrooms are the only significant plant source of vitamin D.
    When exposed to UV light, mushrooms synthesize vitamin D2. Among the richest in vitamin D are:
    Shiitake Mushrooms - They are a good source of vitamin D, especially if exposed to sunlight or UV light.
    Maitake Mushrooms - Also known as "hen of the woods," maitake mushrooms are very rich in vitamin D.
     
  4. Eggs
    Eggs, particularly the yolks, are a good source of vitamin D, considering that one egg yolk contains about 41 IU.

    To maximize intake, it is preferable to choose eggs from free-range chickens, which have more opportunity to synthesize vitamin D due to sun exposure.
     
  5. Fortified Milk and Dairy Products
    In many countries, milk and some dairy products like yogurt and cheese are fortified with vitamin D.
    A glass of fortified milk can contain about 115-130 IU of vitamin D.
     
  6. Fortified Orange Juice
    Fortified orange juice is another good source of vitamin D, especially for those who are lactose intolerant or prefer plant-based alternatives.
    A glass of fortified orange juice can contain up to 100 IU of vitamin D.
     
  7. Fortified Cereals
    Many breakfast cereals are fortified with vitamins and minerals, including vitamin D.
    The amount of vitamin D in fortified cereals can vary, so it is important to read the nutritional label to know how much you are getting.

How to Ensure You Get Enough Vitamin D

In addition to including vitamin D-rich foods in your diet, there are other factors to consider to ensure you get an adequate amount of this essential vitamin:

Sun Exposure: Spending time outdoors and exposing your skin to sunlight is one of the most natural ways to get vitamin D. However, it's important to balance sun exposure to avoid skin damage.

Supplements: In some cases, it may be necessary to take vitamin D supplements, especially for people living in areas with little sunlight or who have a higher risk of deficiency.

Monitoring Levels: Consulting a doctor to check vitamin D levels can be helpful in determining whether you need to make changes to your diet or start taking supplements.


As we have seen, vitamin D is essential for many body functions.

Getting enough of this nutrient through diet and sun exposure is crucial for maintaining good health.

Incorporating vitamin D-rich foods such as fatty fish, mushrooms, eggs, and fortified products into your diet can help you meet the daily requirements of this important vitamin.

Consulting a health professional is always advisable for personalized advice and to ensure you maintain optimal vitamin D levels.
