Vitamin D is a fat-soluble micronutrient that can be found in very few foods. Vitamin D is called sunshine vitamin because it is synthesized by the body when the skin reacts to sunlight. When the summer months begin, most people get the sun from March to September. It is in the cold regions and faces problems and shortcomings during the winter.

Vitamin D can also be absorbed from certain food sources such as fish, egg yolks, fortified dairy, and fish liver oil. Vitamin D is very important because it regulates the body's use of calcium and phosphorous.

Vitamin D deficiency is very common all over the world because it synthesizes from sunlight. About 1 billion people are deficient in this vitamin. Therefore, it is important to understand how to identify the symptoms of vitamin D deficiency and find the right treatment for vitamin D deficiency.

Vitamin D deficiency is known to cause rickets in children and osteomalacia in adults. Rectus is a condition that affects the bones, making them weak and supple. These are known as vitamin D deficiency diseases.

Vitamin D3 was first identified by scientists trying to understand how cod liver oil helps fight rickets. But it's not just the strength of the bones that can be gained from vitamin D.

Symptoms of vitamin D deficiency can range from anything from muscle weakness to mental health. Vitamins are essential for the proper development of nerve functions in the fetuses and also strengthen our immune system. A deficiency can affect brain function.

What causes vitamin D deficiency?

The main reason a person is deficient in this vitamin is exposure to the sun. Combined with low sun exposure, a person may be allergic to milk, which is usually stronger than vitamin D.

People who live in the equatorial get plenty of sunlight and are less likely to be deficient in vitamin D. Here are some other common causes of vitamin D deficiency.

  • Strict adherence to a vegan diet means that there is no possibility of adding vitamin D to any food source.
  • Having very deep skin means a high synthesis of melanin in the skin. When exposed to the sun, it inhibits the synthesis of vitamin D.
  • Older people have less ability to make vitamin D, even if exposed to the sun.
  • Obesity can be detrimental to the production of vitamin D, which is produced by our body's cholesterol when it is exposed to sunlight. Obesity causes cholesterol to build up in the arteries and prevents changes in vitamin D.
  • Regular use of sunscreen when you are out can also stop the production of vitamin D.

What are the symptoms of vitamin D deficiency in adults?

There are several symptoms of vitamin D deficiency. As mentioned earlier, vitamin D deficiency diseases such as rickets are very common due to the skin. Vitamin D deficiency in adults, although less common, manifests as osteoporosis and fragile bones. Other symptoms are listed below.

Getting sick or getting an infection very easily: Because vitamin D is essential for a strong immune system, vitamin D deficiency can make a person very sick. Vitamin D is directly linked to fighting germs that cause infections. Respiratory tract infections that reoccur easily have been linked to vitamin D deficiency symptoms.


Fatigue and Weariness: Observational studies have linked fatigue to low levels of vitamin D in the blood. It is important to take supplements, especially for adult women, when vitamin D levels are dangerously low. If they fail to do so, they run the risk of becoming very tired and exhausted.

Chronic back and joint pain: People with low levels of vitamin D have been reported to have back pain, especially back pain. When there was a deficiency of vitamin D, the bones of the ribs, elbows and knees were also badly affected.

Depression and Anxiety: Mood swings and anxiety can be a sign of vitamin D deficiency. Studies show that low levels of vitamins may be responsible for depression and poor health in many people. It has also been observed that seasonal depression occurs during the colder months when a person is deficient in sun and therefore has a low amount of vitamin D.


Reduced wound healing potential: Studies show that vitamin D deficiency can cause skin tissue to slow down. This means that burns, cuts, and post-surgery tissues will heal very slowly. Vitamin D is also known to reduce inflammation to improve healing. Adequate vitamin deficiencies can adversely affect healing abilities.

Bone loss: Vitamin D deficiency, especially in women, can lead to bone density because vitamin D deficiency indicates that the bones are not properly calculated. Vitamin D deficiency causes poor absorption of calcium and phosphorous in the body and breaks bones.

Hair Loss: Hair loss is usually linked to stress, diabetes, or even post-traumatic stress disorder. But one of the main reasons for this may be the lack of important nutrients in the body. Low levels of vitamin D are known to cause alopecia areata.

Painful muscles: Muscle pain can be caused by a number of reasons. One of them is vitamin D deficiency, which is thought to be a symptom of vitamin D deficiency, as muscle soreness due to the acquisition of nerves that realize that there is less vitamin D and less pain. This can increase pain sensitivity.
