NutraFeast® High Selenium Yeast 2000 is a selenium-enriched yeast derived from a non-GMO yeast strain. This high selenium yeast closely resembles the food-form of selenium available in dietary supplements. ‡
High selenium yeast contains three organic selenium compounds: selenomethionine, selenocysteine, and methylselenocysteine. This form of selenium is more bioavailable and easier for the body to absorb, compared to other types of selenium. ‡
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 protection from infection and oxidative damage.
NutraFeast High Selenium Yeast 2000 is derived from a non-GMO yeast strain, with a selenium salt introduced during active, aseptic, aerobic fermentation.‡
During fermentation, the temperature, pH, and growth rate are closely regulated to ensure proper mineral uptake. The yeast cells take the selenium from the culture medium and
organically bind it to their natural protein matrix, producing a selenium complex from which approximately 70% is selenomethionine. ‡
The resulting product is washed, separated, and held in refrigerated storage to ensure cell
viability and the absence of any “free” mineral. Prior to spray drying, the chilled yeast cream is pasteurized through a high temperature sterilization system to ensure it meets or exceeds established USDA food grade microbial requirements. ‡
The composite sample collected during spray drying and packaging is analyzed for nutrient and microbial composition by external, independent, and certified laboratories. Once the product has met all QA/QC requirements, it is released for sale with a supporting Certificate of Analysis.
High selenium yeast is researched for its potential health benefits: 2, 3, 4, 6, 7, 8, 9, 10, 11‡
High selenium yeast is widely researched and studied to understand its bioavailability and absorption when compared to other forms of selenium. Research is positive for enhanced absorption of high selenium yeast across a diverse population.
Research supports the hypothesis that high selenium yeast exhibits lower toxicity and higher digestibility, absorption, and retention than other forms of selenium.
While the U.S. FDA does not endorse a specific format of selenium in infant formulas, evidence suggests that selenium-enriched yeast is more effectively absorbed and retained than other selenium forms.
Research and clinical trials support the potential positive impacts of selenium supplementation for cancer status.
Lower toxicity and higher digestibility, absorption, and retention than other forms of selenium
May act as an antioxidant and free radical scavenger, thereby guarding against cellular oxidative stress
In general, selenium may provide immune system support
*FDA Qualified Health Claim: Selenium may reduce the risk of certain cancers. Some scientific evidence suggests that consumption of selenium may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive.
