Selenium is one of the essential trace elements. In food, it occurs mainly in the form of selenium-containing amino acids - in plant-based foods mostly as selenomethionine and in animal-source foods as selenocysteine. Since the selenium concentrations in food depend on the concentrations in the soil and thus on the selenium uptake of plants and animals, they can vary greatly depending on the region. In Germany, fish, meat, sausage and eggs are the best natural sources of selenium.

In brief:

Tabelle Selen_en

The German Society for Nutrition (DGE) recommends a daily intake of 60-70 micrograms (µg) of selenium in the diet - an amount that is generally achieved through a balanced diet.

Proposed maximum level for the addition of selenium to food supplements (per daily dose of an individual product):


In order to provide consumers with a significant additional nutrient intake via food supplements when needed and at the same time protect well-supplied people from excessive intake, the German Federal Institute for Risk Assessment (BfR) recommends not adding more than 40 µg of selenium per daily dose to a food supplement.
