German Federal Environmental Agency
The German Federal Environmental Agency states 1-2 µg selenium per kg body weight, corresponding to a quantity of 50-200 µg selenium for an adult per day, as ideal daily selenium supply .
However, with 0.67 µg per kg body weight, the selenium intake per day in Germany is only in the area of the estimated minimum demand of 45 µg selenium per day [1, 2].
European Food Safety Authority EFSA
According to the latest reports of the European Food Safety Authority, an adequate selenium supply can be stated at present only be means of estimated values which are based on experimental values. Accordingly, the estimated selenium supply for adolescents from 15 years and adults per day is 70 µg selenium. This supply quantity shall as well be valid for adult pregnant women. Due to the loss by means of breast-feeding, 85 µg selenium are allocated to breast-feeding mothers. The estimated values for children (from 7 months) and younger adolescents (up to 14 years) are adapted to age and weight with 15-55 µg selenium/day .
However, in principle, the selenium demand is dependent on the individual state of nutrition, selenium metabolism, selenium status and state of health. If the consumption of meat, sausage, fish and nuts is rather low, there is the possibility of the development of a selenium undersupply. If there are additionally problems with the absorption of nutrients in the bowel, the danger for a selenium deficit rises even more. The measurement of the selenium value in blood serum or whole blood can show if the selenium supply via nutrition is reached or if selenium should additionally be taken in.
