Sel-Plex Video


Sel-Plex® is supplied in a form that can be readily stored in tissues because of similarities between methionine and selenomethionine that are interchangeable during protein synthesis. Selenium plays an essential role in metabolism, orchestrating normal growth, supporting normal reproduction, neutralizing free radicals and supporting the body’s normal defense mechanisms against infection. Selenium allows animals to optimize health status during periods of increased demand.

Sel-Plex is Alltech’s proprietary form of selenium-enriched yeast and is the first European Union-approved and only U.S. Food and Drug Administration-reviewed form of selenium-enriched yeast. Supported by more than 19 years of research, Sel-Plex is also the most proven form of selenium-enriched yeast. Alltech is currently the world’s largest producer of natural selenium.
