What Is Brewer's Yeast?
Brewer's yeast is used to make beer, and people have taken it as a dietary supplement for many years. Brewer's yeast is made from a fungus, and it is highly nutritious. It contains iron, protein, and B vitamins, as well as chromium, selenium and other trace minerals. Brewer's yeast is also believed to be a galactagogue, used by nursing mothers to help make more breast milk.
