  • Introduction: Vitamin D is a fat-soluble steroid that acts as a pre-hormonal in the body and regulates blood calcium and phosphate. It is also an anti-rickets vitamin that prevents many diseases in the body. Vitamin D is naturally produced in skin cells under the sun's ultraviolet rays and then becomes active in the liver and kidneys. Vitamin D can also be obtained from foods such as meat and fish liver and some kinds of mushrooms. Vitamin D has several forms, the two most well-known of which are D3 and D2, both of them can be absorbed in the gut.
  • Methods: Methods: In this study, several methods of vitamin D production were investigated. In the first method, the chemical production of vitamin D was investigated using lanoline extracted from sheep`s wool. In the second method, the use of probiotic bacteria to transfer vitamin D to the intestine and in the third method, the production of vitamin D using shiitake mushrooms treated with ultraviolet lamps was studied.
  • Results: The results of this study show that vitamin D deficiency has been observed in different parts of the world and always affects people's health. Also, various factors such as skin color and the direction of sunlight in any geographical area can affect the production of vitamin D in the body. In addition, several factors such as skin color and the direction of sunlight in any geographical area can affect the production of vitamin D in the body. But one of the most important issues is the way people use to wear clothes, which is more pronounced in Muslim-majority countries, in these country people cover most of the body surface and minimize the amount of sunlight received by skin cells (Especially in women).
  • Conclusion: Adequate amounts of vitamin D in the blood can prevent many diseases and abnormalities such as obesity, type 2 diabetes, preeclampsia, periodontitis, cancer death, etc., but many groups of people around the world for some reasons such as low sunlight in the living area they do, Excessive coverage or other items mentioned, producing insufficient amounts of vitamin D is not naturally possible in skin cells. Therefore, the importance of taking vitamin D orally can be seen here. It should be noted that in addition to foods that have different levels of vitamin D, tablets and capsules containing vitamin D are also a good way to compensate for the lack of this vitamin in the body.
