Introduce and benefits
Selenium-enriched yeast , produced by fermenting Saccharomyces cerevisiae in a selenium-rich media, is a recognized source of organic food-form selenium. In this process, virtually all of the selenium structurally substitutes for sulfur in the amino acid methionine thus forming selenomethionine via the same pathways and enzymes that are used to form sulfur-containing methionine. Owing to its similarity to S-containing methionine, selenomethionine is taken up nonspecifically and becomes part of yeast protein. It is this metabolic route that makes selenium-enriched yeast  valuable in animal and human nutrition, since selenium-enriched yeast offers the same organic form of selenium produced by food-chain autotrophs
 
Selenium-enriched yeast supplementation of food-animal diets has an added nutritional benefit to human consumers of food-animal products. Dietary selenomethionine-containing plant or yeast protein can be also stored nonspecifically in animal protein, which can result in nutritionally useful selenium content in meat, milk, and eggs. Consequently, strategies to supplement animal feed with selenium yeast have led to the development of selenium-rich functional foods, including selenium-enriched eggs and meats for human consumption.
