High Selenium Yeast 1200

SelenoExcell® High Selenium Yeast 1200 is a selenium-enriched yeast and is the closest food-form of selenium available as a supplement. It is trusted by leading academic and health institutions.

SelenoExcell is the first selenium yeast product to achieve Generally Recognized as Safe or GRAS status in food. There are also Qualified Health Claims for selenium. This GRAS designation means SelenoExcell can be used across different functional food and beverage categories, including fruit juices, medical foods, grain products and pasta, baked goods, and milk products.

Selenium is an essential nutrient for humans. This trace element is a constituent of over two dozen selenoproteins, with roles in DNA synthesis, thyroid hormone metabolism, reproduction, and immune health and oxidative stress.1, ‡

What is SelenoExcell®?

SelenoExcell® is an organically-bound high selenium yeast originating from a non-pathogenic, non-GMO Saccharomyces cerevisiae yeast strain. During its growth, it creates compounds resembling food forms of selenium, similar to those found in Brazil nuts, eggs, peas, and meats.


The S. cerevisiae cells in SelenoExcell® are inactive, and only the nutritional properties remain. The cells cannot reproduce in the human body when consumed because they are no longer alive.


SelenoExcell®'s yeast fermentation process replicates the natural course in which plants absorb and transform minerals from the soil into a more bioavailable form, supporting the nutrition and health potential of selenium. The yeast accumulates, encouraging the incorporation of selenium into the protein structure, supporting antioxidant properties that may reduce oxidative stress in the body.


Research and testing comparing SelenoExcell® to other non-food forms of selenium suggest potential positive impacts.10

What is High Selenium Yeast?

High selenium yeast is a selenium supplement derived from the cultivation of the Saccharomyces cerevisiae yeast strain. Yeast cells absorb selenium and transform it into selenomethionine, a form of selenium that is naturally present in food. 2

Research shows that high selenium yeast exhibits lower toxicity and exhibits higher digestibility, absorption, and retention than other forms of selenium. 3, 4

Selenium is an essential mineral, providing antioxidant, immune system, and thyroid hormone support. 1, 5, ‡



  The 1996 Nutrition Prevention Cancer Trial (NPCT) Phase 3 supplementation trial, published in the Journal of American Medical Association (JAMA), supported positive results for individuals with cancer. In this clinical study, individuals received a daily 200 µg selenium supplement of SelenoExcell. 7
