Vitamin D is an extremely important vitamin that has strong effects on the human body. Unlike other vitamins, vitamin D acts like a hormone, and every single cell in our body has a receptor for it. It is also found in certain foods like fatty fish and fortified dairy products, although it is very difficult to get enough of it just from the diet.

The recommended daily intake of vitamin D is usually around 400-800 IU, but many experts say you should take more. Especially because vitamin D deficiency is very common and it is estimated that about one billion people worldwide have low levels of vitamins in their blood.

According to a 2011 study, 41.6% of adults in Americans are deficient in vitamin D, and these are the seven groups that are more likely to suffer from a deficiency of this vitamin:

  • people who have dark hair
  • elderly people who are overweight
  • people who don’t eat a lot of fish or dairy products
  • people who live in places with little sun
  • people who always use sunscreen
  • people who often and a lot stay indoors

Most people do not realize they have vitamin D deficiency because the symptoms are generally subtle and not easily recognized even though they have a significant and negative impact on quality of life, and these are the six most common symptoms.

One of the most important roles of vitamin D is to strengthen the immune system so that it can fight viruses and bacteria that cause disease. It communicates directly with the cells responsible for fighting the infection, and if you get sick often, especially when it comes to colds or flu, low levels of vitamin D can be a contributing factor. But numerous studies have found that taking vitamin D supplements at a dose of up to 4,000 IU a day can reduce the risk of a respiratory infection.
