No evidence for an impact of selenium supplementation on environment associated health disorders – a systematic review

The role of organic selenium in cadmium toxicity: effects on broiler performance and health status

“…Several studies showed that the organic form of Se has higher bioavailability and provides better antioxidant protection than inorganic form (Mahmoud and Edens, 2003;Lacour et al, 2004). In the present study, addition of 10 mg/kg Cd to broilers' diets showed no negative effects on performance and mortality, whereas addition of 100 mg/kg Cd caused significant negative effects on performance such as reduced body mass, decreased feed consumption and increased FCR.…”

Supplementation of cultivated mushroom species with selenium: bioaccumulation and speciation study

“…Moreover, the presence of inorganic Se species in fruiting bodies does not reduce the nutritional value of studied mushrooms, as supplementation of both forms, organic and inorganic, was found to generate desired clinical outcomes [39]. In the present work, which is a continuation of our previous research [26], the Se content in organic compounds was determined as a summary value, without determining the content of particular organic forms of this element: selenomethionine Se-O, S-(methylseleno)cysteine and selenomethionine [40][41][42]. Despite contradictory results on the significance of particular organic Se forms (selenomethionine vs Se-(methyl)selenocysteine) in prevention of certain diseases such as cancer [6], all organic forms are well absorbed [43] and used for selenoprotein biosynthesis [44].…”

Arzneiverordnungs-Report 2010

“…Bei stationären Patienten wird dagegen eine Hypomagnesiämie in 6-11% der Fälle beobachtet (Manz et al 1990. Insbesondere gibt es keine Belege für den Nutzen einer Selensupplementation bei geriatrischen Patienten (Lacour et al 2004). B.…”
