Selenium (Se) is an essential nutrient for life, with established requirement from 0.1 – 0.3 ppm to support basic functions.

While inorganic Se are commonly used for feed supplements, the recent research has firmly confirmed that organic Se, specifically seleno-methionine (Se-Met) or hydroxy-selenomethionine (OH-SeMet), is much easily integrated into body metabolism.

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 that exists in both forms : powder and liquid.
