7 Subtle Signs That You May Have a Vitamin D Deficiency

7 Subtle Signs That You May Have a Vitamin D Deficiency

Vitamin D is an extremely important vitamin that is very important for a healthy body. Unlike other vitamins, vitamin D acts as a hormone, and every cell in the body needs it. Usually we do not have to put a lot of effort into getting this vitamin because you absorb vitamin D as soon as your skin is exposed to the sun.

Certain foods, such as fish and dairy products, also contain a lot of vitamin D. Therefore, a vitamin D deficiency does not occur frequently in the summer, but as soon as the winter has arrived, more and more people suffer from unexplained symptoms that may be caused due to a vitamin D deficiency.

The recommended daily amount of vitamin D is set at 10 micrograms per day for men and women up to 70 years. For adults over 70, the recommended daily allowance is 20 micrograms per day, but many experts say that you actually need more. Unfortunately, vitamin D deficiency is common. An estimated 1 billion people worldwide have a low vitamin content in their blood. This is often because these people fall within a certain risk group. The 7 common risk groups for vitamin D deficiency are:

  • People with tinted or dark skin
  • People who are over 70
  • People who are overweight or obese
  • People who eat little or no fish or dairy (for example most vegans).
  • People who live far from the equator and therefore receive less sunlight
  • People who are usually inside

Most people do not realize that they are deficient because the symptoms are generally subtle and unobtrusive. You may not easily recognize them, even if they have a significant negative effect on your quality of life. The common symptoms of a vitamin D deficiency are:

You Often Get Sick


If you often get sick (such as a cold or the flu), low vitamin D levels can be a contributing factor. Various studies have shown a link between vitamin D deficiency and respiratory infections such as colds, bronchitis and pneumonia. A number of studies have shown that taking vitamin D supplements daily can reduce the risk of respiratory infections.

You Are Often Tired

If you feel tired it can have many causes, and vitamin D deficiency can be one of them. Unfortunately, this cause is often overlooked. Studies have shown that vitamin D deficiency can cause fatigue, which has a serious negative effect on quality of life. 

Bone and Back Pain

Vitamin D helps to maintain bone health in various ways. First, it improves the absorption of calcium in the body. Bone pain and lower back pain may be signs of insufficient vitamin D levels in the blood. Large studies have found a link between vitamin D deficiency and chronic (low) back pain.


Some people sometimes say that they have winter depression because they get sad of the cold and the rain. But a depressed mood can also be a sign of vitamin D deficiency. In overview studies, researchers have linked vitamin D deficiency to depression, especially among older adult

Slow Wound Healing

Slow healing of wounds after surgery or injury can be a sign that the vitamin D levels are too low. Results of a study suggest that the vitamin boosts the production of substances that are crucial to the formation of new skin as part of the wound healing process. 

Hair Loss

Hair loss is often attributed to stress, which is certainly a common cause. But when hair loss is a common occurrence, it can be due to an illness or a lack of nutrients. Hair loss among women has been associated with low vitamin D levels, although little research has yet been done. Vitamin D not only ensures that the hair falls out less quickly, but it also ensures a healthy structure of the hair.

Muscle Pain

The causes of muscle pain are often difficult to determine. There are indications that vitamin D deficiency can be a possible cause of muscle pain among both children and adults. In one study, 71% of people with chronic muscle pain appeared to be deficient. You can easily solve this by taking vitamin D supplements daily.
