Selenium exists in all cells and is an essential component of many enzymes. The selenoproteine fulfil important functions in the body and are active in terms of cell protection in order to catch free radicals. In this context, selenium contributes to the protection of important cell components, such as the genetic information, from oxidative stress. Moreover, a sufficient supply with selenium is important for a normal function of the immune system and the thyroid. Likewise, selenium makes a contribution to the normal development of sperms and to the maintenance of normal hair and nails.
Since the body cannot build selenium, it has to be supplied daily. A selenium deficiency can develop in case of digestive disorders or insufficient supply via nutrition (e.g. vegetarians, vegans).
The selenium (sodium selenite), used in Cefasel, is directly available for the specific incorporation into the selenium-dependent enzymes.
Cefasel is available in different dosage forms (tablets, drops, ampoules) and strengths (50 µg, 100 µg, 300 µg selenium).
