Zinc Excell® Yeast 1.5% originates from a non-pathogenic, non-GMO Saccharomyces cerevisiae yeast strain. We believe it is important to consume minerals and vitamins that are as close to the natural food form as possible, and at the same time can have consistent composition in every batch. 
 
The S. cerevisiae cells in Zinc Excell® 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. 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. The yeast is able to accumulate and incorporate zinc into the protein structure, enhancing the effectiveness of the mineral.
