Sources and absorption of vitamin D
In the area of proper human nutrition, both vitamin D2 and D3 play the crucial role. In the human body, these vitamins are formed under the influence of sunlight (vitamin D3) or supplied with food (vitamins D2 and D3).
The most common cause of vitamin D deficit is the lack of exposure to sunlight due to lifestyle (working indoors), as well as fear of exposure to the sun and the use of cosmetics with UV filters improperly.
