Brewer's yeast is made from different yeast (Saccharomyces) species. It’s collected
during the process of brewing beer. It can also be grown in a nutrient broth. This
can change its mineral content.
Brewer's yeast is 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. For
example, adding chromium increases the chromium content of the yeast, and adding selenium
increases its selenium content.
Medically valid uses
Yeasts have been used for centuries in a variety of ways. They’ve been used to raise
bread, brew beer, and make wine and alcoholic drinks. Brewer's yeast has been used
as a supplement of B vitamins. More recently, it’s been used as a supplement for minerals.
These include chromium and selenium.
There may be benefits that have not yet been proven through research.
Yeast may help treat eczema, gout, infectious diarrhea, and some heart problems. It
may help lower cholesterol and boost the immune system. It may also improve physical
and mental health. Brewer’s yeast may also help control diabetes. It does this by
aiding in sugar metabolism (yeast with a high chromium content only) and reducing
appetite. It also reduces the side effects of contaminants and pollutants.
The suggested dose varies.
Women who are pregnant or breastfeeding should ask their healthcare providers before
taking any supplements.
Side effects, toxicity, and interactions
Brewer’s yeast may cause gas. If you are prone to migraines, taking brewer's yeast
may cause them.
Brewer’s yeast may interact with medicines to treat depression called monoamine oxidase
inhibitors (MAOIs). People with gout or Crohn's disease should not take brewer’s yeast.
There are differences between brewer's yeast, baker's yeast, nutritional yeast, and
torula yeast. Brewer's yeast and nutritional yeast have many of the same nutrients.
