9 Brewer’s Yeast Benefits, Sources, Dosage And Deficiency

Brewer's Yeast

Yeast and its many medicinal properties were discovered by the human race thousands of years ago. Almost all forms of yeasts thrive on organic elements and thus are not dependent on the Sun’s energy. Yeast is a living organism and it requires either an acidic pH or a neutral environment to grow and develop. As yeast grow and form colonies of cells they indulge in the process of fermentation whereby they release carbon dioxide and alcohol as byproducts.

One of the most popular types of yeast used by man since ages is the Brewer’s yeast. Many people think that Brewer’s yeast is only required for baking breads and brewing beers however, it is also used as a nutritional supplement and offers many medicinal benefits too. In this article we research in detail about the various properties, benefits, sources and the right dosage of Brewer’s Yeast.

What Is Brewer’s Yeast

In scientific terms, Brewer’s yeast contains a fungus called Saccharomyces cervisiae that is actively involved in the fermentation of carbohydrates and releases carbon dioxide. The carbon dioxide helps in the ‘brewing’ of the beer and the rising of the baker’s dough.

The most common use of Brewer’s yeast is for brewing beers. During the process of brewing the yeast is added to hops and malted barley to allow the fermentation process to initiate and to get it converted into alcohol. It takes more than one week for the yeast to ferment the beer completely and it is done under varying yet controlled temperature levels.

As mentioned above, apart from its culinary properties Brewer’s yeast is a known source of Vitamin B complex. The following B-Complex vitamins are found in the Brewer’s yeast – Vitamin B1 -Thiamine, Vitamin B2 – Riboflavin, Vitamin B3 – Niacin, Vitamin B5 – pantothenic acid, Vitamin B6- pyridoxine, Vitamin B7 – Biotin and Vitamin B9 – Folic Acid.
