Selisseo® 2% Se is an organic source of selenium consisting of hydroxy-selenomethionine or HMSeBA diluted on silica carrier, to be used in all species to supply 100% efficient selenium. Selisseo® 2% Se is the only pure source of hydroxy-selenomethionine on the market.
The selenium content of each ALKOSEL® R397 production batch is standardized using state of the art analytical techniques such as flame atomic absorption spectrometry (FAAS). The total selenium content in ALKOSEL®R397 is guaranteed to be 2000 ppm minimum and is almost totally in its organic form (>98%). Furthermore, the strain Saccharomyces cerevisiae NCYC R397 has been specifically selected for its selenium bioavailability properties.
