Optimin SeY

Optimin SeY is an inactivated yeast enriched with selenium (Se). Its production process imitates the natural way organic selenium is incorporated into plants. Like plants, the specific strain used in Optimin SeY (Saccharomyces cerevisiae) absorbs inorganic selenium and converts it into organic selenium, which is incorporated mainly into selenomethionine (SeMet) and selenocysteine (SeCys). Optimin organic selenium provides a combination of various forms of natural organic selenium. It contains both selenomethionine (SeMet) and selenocysteine (SeCys) as well as other seleno-compounds unlike synthetically produced seleniums that contain only selenomethionine. This accounts for the superior bioavailability of Optimin SeY.

About Optimin

ORGANIC trace minerals​

Trace minerals are essential to maintain fertility, health and immunity. The nutritional success of any organic trace mineral depends on the ability of the organic escort to hold onto and protect the mineral from undesirable reactions. Optimin’s superior chelation stability maintains the chelate’s integrity and keeps the organic mineral in its original form during digestion and help it survive the environment of the gastrointestinal tract until its absorption.
