According to the National Institute of Health, selenium helps make special proteins, called antioxidant enzymes, which play a role in preventing cell damage.
Selenium intake depends largely on soil conditions in the region food is grown or raised. And, certain types of soils prevent selenium from being taken up by crops and pasture grasses. Thus, selenium intake can vary depending on geographic region. Unless all your food comes from a single known region, it’s difficult to know exactly how much selenium you are getting in your diet.
SelenoExcell originates from a non-pathogenic, non-GMO Saccharomyces cerevisiae yeast strain. It creates a product that is the closest to food forms of selenium, like what is found in Brazil nuts, eggs, peas, poultry, and meats. We do this because we believe it is important to consume minerals and vitamins that are as close to a natural food form as possible. However, the S. cerevisiae cells in SelenoExcell are dead or inactive, and only the nutritional properties remain. The cells cannot reproduce in the human body when consumed because they are no longer alive.
In the case of SelenoExcell, S. cerevisiae is used as a means to an end. The yeast fermentation process replicates the natural course in which plants absorb and transform minerals from the soil into a more bioavailable form that improves the nutrition and health properties of selenium. This particular yeast is able to accumulate and incorporate selenium into the protein structure, which enhances the antioxidant properties, which fight oxidative stress in the body.
Selenium from ‘high selenium yeasts’ contain as much as 1,000 to 2,000 micrograms of selenium per gram. The form of selenium in SelenoExcell is what researchers call organic, meaning it is attached to several amino acids. This factor may make it more bioavailable than others.
