The SEL-PLEX® Advantage

The central advantage of supplying selenium as SEL-PLEX is the ability of the animal to store its natural form. Tissue reserves of selenium are critical during times of increased need, such as immune challenge and reproduction. Benefits will be seen in terms of animal health, productivity and increasing the nutritional value of animal products for humans.

Why is Selenium Important?

Selenium is an essential nutrient for animals and people. Selenium plays an essential role in metabolism, assisting normal growth, supporting reproductive efforts, neutralizing free radicals and supporting the body’s normal defense mechanism against infection.


SEL-PLEX is Alltech’s proprietary organic form of selenium yeast manufactured to mimic Mother Nature, thus better absorbed, stored and utilized by the animal than inorganic selenium. Supported by more than 20 years of research, SEL-PLEX is the most researched and proven form of organic selenium available and has consistently been shown to improve animal performance and the quality and nutritional value of meat, milk and eggs.

SEL-PLEX is also the only FDA reviewed form of organic selenium, and is the first strain specific form of organic selenium to be EU approved for all species. Alltech is currently the world’s largest producer of natural, organic selenium yeast.
