The Amazing Health Benefits of Brewer’s Yeast

Brewer’s yeast, scientifically known as Saccharomyces carlsbergensis, Saccharomyces uvarum, Saccharomyces cerevisiae, and Saccharomyces pastorianus, is very rich in amino acids, vitamins, and trace minerals. Adding this inactive yeast to your diet can strengthen your immune system.

Brewer’s yeast is a type of inactive fungus that is widely used commercially to brew beer as well as an important ingredient in baking bread. It is also being used as a nutritional supplement for years. When brewer’s yeast is combined with carbohydrates, for instance grains, they ferment them to produce what is branded as beer. When it comes to baking, it is the brewer’s yeast that causes the dough to gradually rise. Several vitamins and minerals essential to the human body can be found on the brewer’s yeast that is why it is being used as a nutritional supplement.

Nobody wants to miss out on the numerous benefits this yeast has to offer. Here are a few of its amazing nutritional benefits:

Vitamin B Complex

Brewer’s yeast contains vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin) and B9 (folic acid). These vitamins aid body functioning especially in the breakdown of fats, proteins, and carbohydrates to produce energy. These vitamins also assist the nervous system and help sustain the digestive muscles for proper digestion.

Essential Trace Minerals

These minerals are necessary for our body’s daily functions. Our body cannot produce them on its own so they have to be ingested.

Brewer’s yeast is one of the richest sources of the essential mineral called chromium. This mineral is an antioxidant that combats free radicals in our body that may cause cancer and degenerative diseases. It also helps the body in maintaining normal blood glucose levels by facilitating effective use of insulin. Insulin serves as a key to unlock the conversion of carbohydrates, proteins, and fats to energy that our body can use. Without that key (which is insulin), the glucose levels in the blood increases radically. When this increase in blood glucose level is prolonged, it may lead to diabetes and other complications.

Another essential trace mineral that is abundant in brewer’s yeast is selenium. It improves immune system and thyroid functions. It also acts as an antioxidant that combat free radicals that can cause cellular damage.


Brewer’s yeast contains all the essential amino acids. Like essential trace minerals, they have to be ingested because our body is not capable of producing them. Our body uses all the 22 amino acids to construct 50,000 more proteins we need in order to be healthy. Although of these 22 amino acids, only 8 are classified as essential. Protein has many functions in our body like building and repairing tissues, muscles and bones.


Remember that just like any medication, brewer’s yeast is not well-tolerated by every individual. It is advisable not to take in massive amounts as it may cause side effects such as gas, bloating, headache, and itching. In other words, consume brewer’s yeast under moderation. Consult your physician when you experience any problem in using brewer’s yeast.
