alkosel® R397 is a specific inactivated whole cell yeast (Saccharomyces cerevisiae) product containing the essential trace element selenium in its natural food form, L(+) selenomethionine.

It is produced by growing yeast in the presence of measured amounts of selenium. This specific yeast strain absorbs selenium and biochemically transforms it into the highly bioavailable L(+) selenomethionine and other seleno-proteins.

Selenomethionine is naturally found in edible plant protein but only at very low concentration.

It is the most suitable form of selenium for animal nutrition.

Registration
Europe: alkosel® R397 is registered (EC No.3b8.11) as a nutritional feed additive for all animal species. This registration is specific to the Lallemand yeast strain of Saccharomyces cerevisiae NCYC R397 used in the manufacture of alkosel® R397.
