Vitamin D Deficiency: Why It's Common

Vitamin D is an essential nutrient for our body. It helps absorb calcium and helps maintain strong bones. However, many people do not get enough vitamin D. In this article, we look at why vitamin D deficiency is common.

Causes of vitamin D deficiency

1. Lack of sunlight

Vitamin D can be produced by the body itself when the skin is exposed to UV-B rays. However, if you live in a country with little sun or spend a lot of time indoors, your body may not be able to make enough vitamin D.

2. Dark skin

People with dark skin have more melanin and can therefore produce less vitamin D than people with light skin.

3rd age

As we age, skin becomes thinner and produces less vitamin D. Older people often also have weaker immune systems and are less able to absorb vitamin D from food.

4. Nutrition

Vitamin D is found in some foods, such as fish, mushrooms and eggs. However, it can be more difficult to get enough vitamin D on a vegetarian or vegan diet.

5. Diseases

Certain diseases can prevent the body from properly absorbing or metabolizing vitamin D.

Symptoms of vitamin D deficiency

A lack of vitamin D can cause a number of symptoms:

  • fatigue
  • muscle weakness
  • bone pain
  • mood swings
  • infections

Prevent vitamin D deficiency

There are several ways to ensure you're getting enough vitamin D :

  • Spend more time outdoors and expose your skin to sunlight. Be careful not to burn yourself!
  • In your diet, pay attention to foods containing vitamin D such as oily fish, eggs and mushrooms.
  • Use supplements if you're not getting enough vitamin D from sunlight and food. Make sure you stick to the recommended dosage.


Vitamin D deficiency is common and can lead to a variety of symptoms. Getting enough sunlight and eating a balanced diet are important to ensure your body is getting enough vitamin D. If you're concerned about your vitamin D status, talk to your doctor.
