How is vitamin D produced?

Our body, our skin, can produce vitamin D3 under the influence of sunlight. The ultraviolet radiation (UV-B) from sunlight activates the production of provitamin D, which is then converted into vitamin D3 (cholecalciferol). This sounds simple, but there are a number of conditions attached to it. This process is only started when the sun power is at least 3. For sufficient vitamin D production, it is recommended to expose yourself to the sun for at least a quarter to half an hour between 12:00 and 15:00. In addition, children, the elderly and people with a tinted or dark skin tone produce less vitamin D.
