Brewer's yeast is made from different yeast (Saccharomyces) species. It’s "harvested" during the beer-brewing process. It can also be grown in a nutrient broth for improved yield. This can also change its mineral content.
It’s a good source of protein. Protein makes up 52% of its weight. It’s also a good source of B-complex vitamins. The mineral content of brewer's yeast can be controlled by adding minerals to the solution in which the yeast is grown. Adding chromium increases the chromium content of the yeast. Adding selenium increases its selenium content.
Domesticated yeasts have been used for centuries. They’ve been used to raise bread, brew beer, and make wine and alcoholic beverages. Brewer's yeast has been used as a nutritive supplement for B vitamins. More recently, it’s been used as a supplement for minerals. These include chromium and selenium.
