The Vitamin D 20 µg contains the by the DGE (German Association for Nutrition) as appropriate considered intake of 20 µg for vitamin D for the daily supply of the body.
With regular exposure to sunlight, Vitamin D can be formed by the body itself. This self-production is not always sufficient due to various factors e.g. solar radiation in autumn and winter months, too short stays outdoors etc.
Vitamin D has a key role for the health of the human body. It’s involved in thousands of regulation processes in the human somatic cells. Therefore, a lack of vitamin D increases monumentally the risk of disease.
