11 Surprising Brewer’s Yeast Benefits – Nutrition, Uses

Brewer’s yeast is a nutrient-rich food with many health advantages. This budding yeast is very good for the gut and may boost both immunity and energy. But, it has some side effects and isn’t good for everyone. Keep reading to find out about the advantages and disadvantages of ingesting brewer’s yeast.

What’s Brewer’s Yeast?

Brewer’s Yeast was originally produced as a by-product of beer brewing and has a bitter taste. Nowadays, it’s dried and used as a nutritional supplement.

Especially, it’s produced from Saccharomyces cerevisiae, a type of yeast that has been used in baking and brewing since ancient times.

S. cerevisiae has a broad arrange of supposed beneficial health consequences like lowering cholesterol, boosting the immune system, and diminishing inflammation.

“Brewer’s yeast” can refer to:

  • The energetic type of S. cerevisiae that’s used for brewing
  • The leftover S. cerevisiae in the brewing process that’s used as a supplement. This type includes a strong bitter flavor
  • S. cerevisiae which was developed on grain

Supplemental brewer’s yeast is usually grown on a medium of corn and other types of grain.


Brewer’s yeast is full of protein, B-vitamins, and chromium (some of the newer “debittered” forms do not have chromium).

But, The nutrient profile changes depending on the grain on which the yeast is grown, how it’s processed, and whether it’s been fortified with additional nutrients.

Generally, S.cerevisiae includes:

  • B Vitamins (B1, B2, B3, B6, Folate)
  • Minerals (Potassium, Chromium, Zinc, Selenium, Lithium, Magnesium, Phosphorous, Copper)
  • Protein
  • Probiotics
  • Prebiotics (Mannan-oligosaccharides (MOS), beta-glucans)
  • Anti-inflammatories and immune stimulants (beta-glucans)
  • Nicotinamide riboside
  • Nucleotides: DNA and RNA
  • Ergosterol — those have pro and anti-estrogenic properties. It inhibits breast cancer.

Out of all these ingredients, the most interesting ones to many Contemporary researchers are beta-glucans, nicotinamide riboside, and DNA and RNA nucleotides. Nucleotides in whole meals have recently been associated with increased energy and maybe even cognitive functioning.

Can Be Brewer’s Yeast Exactly the Same as Nutritional Yeast?

Brewer’s yeast and nutrient yeast are near relatives, so it’s easy to confuse them. Nutritional yeast is also manufactured from S. cerevisiae; the difference is in how the yeast is cultivated.

Their Nutritional profile is also comparable. Both are a rich source of B vitamins, which support the metabolism of carbohydrates, fats, and proteins. Unlike nutritional yeast, brewer’s yeast is also saturated in iron, selenium, zinc, and potassium. Brewer’s yeast is also a fantastic source of protein, providing essential amino acids that the body doesn’t make by itself.

Even though Nutritional yeast is also a fantastic source of protein and B-vitamins, it includes little to no chromium. It’s usually fortified with vitamin B12 and folic acid (B9).

And unlike brewer’s yeast, nutritional yeast has at all times been cultivated especially for its nutrition. It’s grown on glucose medium, which makes it gluten-free; based on the medium it’s increased on, brewer’s yeast could contain gluten.

Nutritional yeast is S. cerevisiae that is grown solely for supplemental use. It is usually fortified with vitamin B-12 and folic acid.

Brewer’s yeast and nutrient yeast are both S. cerevisiae, but brewer’s yeast is a byproduct of grain fermentation, while nutrient yeast was grown specifically for supplemental use and is often fortified with B vitamins.

Benefits of Brewer’s Yeast

Supplemental Brewer’s yeast hasn’t been approved by the FDA for clinical use. Supplements generally lack solid clinical research. Regulations set manufacturing criteria for them but don’t guarantee that they’re effective or safe. Speak with your doctor before supplementing.

Insufficient Proof For

The following purported benefits are only supported by limited, Low-quality clinical studies. There is inadequate evidence to support the use of brewer’s yeast to get some of those below-listed uses. Don’t forget to speak with a doctor prior to taking brewer’s yeast as a supplement, rather than use it in place of something your physician recommends or prescribes.

1) Gut Health & Diarrhea

Cerevisiae is believed to promote bowel health by:

  • Clearing away bad germs while supporting good bacteria
  • Preventing harmful germs and fungal toxins from adhering to the intestines
  • Preserving gut barrier integrity
  • Decreasing inflammation
  • Fighting infections

A number of these effects are mediated by the presence of prebiotics at S.cerevisiae (i.e. beta-glucans and mannan-oligosaccharides) in addition to nucleotides.

Brewer’s yeast improved the results of C. difficile-associated diarrhea in humans, but the evidence is restricted to a few human cases.

However, brewer’s yeast lacks the probiotic effects, such as improved nutrient absorption and additional intestine microbiome benefits. All these are confined to supplements with residing S. cerevisiae.

Saccharomyces boulardii is the only form of yeast currently approved for probiotic Use in humans because of its clinical efficacy in treating diarrhea and other bowel disorders. Talk with your doctor before using brewer’s yeast to handle diarrhea or some other gut condition.

Brewer’s yeast is thought to be a beneficial species for the human gut flora. It might have some advantages for nausea.

2) Type 2 Diabetes

Brewer’s Yeast is obviously full of the glucose tolerance factor (GTF), a compound that includes a biologically-active form of chromium.

GTF diminished blood sugar, creatine, and LDL (“bad”) cholesterol levels and increased amounts of HDL (“good”) cholesterol in rats and humans with type 2 diabetes.

Additionally, it prevented eye and kidney injury in diabetic animals.

The glucose tolerance variable achieves these effects by mimicking insulin. It can:

  • Trigger proteins involved in insulin signaling pathways.
  • Enhance glucose transport.
  • Promote glycogen storage.

The glucose tolerance factor additionally enhanced the action of insulin, helping it to bind to cells.

Though Some human studies have produced promising results, much more study is required to ascertain whether brewer’s yeast has a part in managing diabetes.

Brewer’s yeast includes glucose tolerance factor, a compound that decreased blood glucose and enhances cholesterol profile in human trials.

3) Energy and Mood

S.cerevisiae is a natural dietary source of nucleotides. Nucleotides enhanced endurance and post-workout recovery in athletes, which may indicate a usage for brewer’s yeast in reducing fatigue.

Patients with chronic fatigue syndrome Are often deficient in many nutrients, which may worsen symptoms. A nutritional supplement according to brewer’s yeast (Nagipol) improved cognitive function and mood in chronic fatigue syndrome sufferers. The authors indicated that brewer’s yeast may be a useful remedy for this poorly-understood disorder.

Brewer’s yeast contains lithium, an element traditionally used to treat mood disorders. Obviously lithium-rich brewer’s yeast enhanced mood in former drug users.

However, This proof is still considered insufficient to recommend brewer’s yeast for exhaustion. Future studies will determine whether it’s safe and effective for this use.

Nutrients in brewer’s yeast can reduce fatigue and improve recovery following physical exertion.

4) Healthy Skin

Cosmetic products containing S.cerevisiae extract enhanced skin moisture, brightness, and smoothness in volunteers.

These outcomes could be explained by the abundant proteins, beta-glucans, minerals and vitamins in S.cerevisiae. These elements are thought to have wound healing, hydrating, and antioxidant properties.

5) Healthy Weight

In a study of 54 obese women and men, yeast hydrolysate reduced body fat and stomach fat without any negative effects on lean body mass.

All these Results coincide with data from previous animal and human studies demonstrating decreased body weight and body fat following yeast hydrolysate supplementation.

Yeast hydrolysate is a nutritional supplement with refined and concentrated S. cerevisiae, and brewer’s yeast may not have the very same results on weight reduction.

Yeast (from S.cerevisiae) lessens the hunger hormone ghrelin in mice, which may partly explain the reduction in body fat.

It also decreases fat manufacturing by lowering the action of liver enzymes required for producing fatty acids.

In Addition, nicotinamide riboside (found in brewer’s yeast) increases enzymes involved in fat burning (sirtuins) and energy usage, thereby raising weight loss.

The Best way to drop weight is to eat a healthy diet and commit to a workout program. Brewer’s yeast might be a part of that healthful diet, however, it’s important to speak to your doctor before using it, in order to prevent unexpected interactions or side effects.

In limited clinical trials, supplementing with brewer’s yeast promoted weight loss and diminished fat production.

6) Heart Disease

Dietary Brewer’s yeast is under investigation because of its potential against heart disease since it has enhanced cholesterol and blood pressure levels in animals and humans.

Brewer’s yeast Includes many cholesterol-lowering vitamins and minerals:

  • Beta-glucans
  • Niacin (which also increases HDL levels)
  • Nicotinamide riboside
  • Glucose tolerance factor

Consuming brewer’s yeast every day lowered LDL cholesterol and triglyceride levels and increased HDL cholesterol in a little analysis of 55 types 2 diabetic patients with high blood glucose.

Aside From lowering cholesterol, brewer’s yeast may also decrease blood pressure. 1 research in 90 adults with type 2 diabetes found that brewer’s yeast significantly lowered blood pressure.

The high levels of magnesium, potassium, and calcium In brewer’s yeast can explain this decrease in blood pressure. According to some studies, a larger intake of these minerals can reduce the risk of hypertension, heart disease, and stroke.

Brewer’s Yeast also comprises proteins that help reduce blood pressure by decreasing the activity of the angiotensin-converting enzyme (ACE). Higher activity of the enzyme is linked to high blood pressure.

Brewer’s Yeast has not yet been approved for the purpose of reducing cholesterol and shouldn’t be utilized in place of strategies and therapies recommended by your health care provider.

Brewer’s yeast supplementation improved cholesterol profile also reduced blood pressure in clinical trials.

7) Brain Health and Cognitive Role

Brewer’s yeast is a natural supply of nicotinamide riboside, a kind of vitamin B3 that’s a precursor to nicotinamide adenine dinucleotide (NAD).

Nicotinamide riboside safely raised levels of NAD in animals and humans.

Higher levels of NAD protect nerve cells and may prevent neurodegenerative disease.

Increasing NAD amounts with nicotinamide riboside restored cognitive function in a mouse model of Alzheimer’s disease.

Additionally, nicotinamide riboside slowed nerve degeneration by arousing NAD pathways, which could help preserve brain cells following injury.

More Human research will be required to determine what impact brewer’s yeast might consistently have on cognitive function and neural health.

Nutrients in brewer’s yeast improved NAD, a marker of cognitive functioning, in a small human trial. But, brewer’s yeast supplementation has not been directly linked to cognition.

8) Premenstrual Syndrome

Brewer’s Yeast in combination with minerals and vitamins relieved premenstrual pain in 40 women with mild to moderate premenstrual syndrome.

Larger, more robust studies will be required to verify this benefit.

Animal & Cell Research (Lacking Evidence)

No Clinical evidence supports the use of brewer’s yeast to get some of the conditions listed in this part. Below is a list of the present creature and cell-based research, which ought to guide additional investigational efforts. However, the research listed below should not be interpreted as encouraging of any health advantage.

9) Immunity

Beta-glucans (sugars found in the cell walls of yeast, bacteria, and fungi) can activate the immune system.

They enhance the purpose of the primary immune system cells, including macrophages, neutrophils, and natural killer cells.

Beta-glucans Bind to specific receptors on these cells, initiating a wide variety of beneficial immune reactions (e.g., anti-inflammatory cytokine generation).

However, Not all of the beta-glucans are equivalent. Beta-glucans derived from different sources have unique structures that lead to different effects.

Cell research indicates that beta-glucans from yeast (i.e., beta-1–3-glucan) have the best capability to trigger the immune system.

Beta-glucans derived from S.cerevisiae have revealed promising results such as:

  • Reduced prevalence of the viral, bacterial, and fungal disease in mice and humans
  • Reduced allergy symptoms in mice and humans
  • Reduced occurrence of post-operative disease in humans and animals
  • Reduced inflammation and quicker wound healing in animals and humans
  • Reduced speed of cancer tumor size and increase in animals
  • Enriched regeneration of white blood vessels after radiation from mice
  • Reduced inflammation in mouse models of arthritis

Cell studies suggest that beta-glucans from brewer’s yeast could activate elements of their immune system, however, this hasn’t yet been verified in humans.

10) Hearing Loss

Nicotinamide riboside, a kind of vitamin B3 found in brewer’s yeast, averted noise-induced hearing loss in mice. It decreased nerve cell damage caused by noise exposure.

This impact has not yet been replicated or even tested in people.

11) Pregnancy

S.cerevisiae is a rich dietary source of folate, a vitamin that will help prevent major birth defects.

Oxidative stress is a significant cause of hypertension in pregnancy that ends in complications to the mother and fetus. S. cerevisiae diminished oxidative stress in bronchial cord red blood cells, And the authors indicated that it could possibly be useful in reducing oxidative damage to the embryo. But this was a cell study, and their theory has not been examined in living animals or humans.

Even though The requirement for folate during pregnancy is well-established, the impact of brewer’s yeast on a pregnant woman or her unborn child isn’t certain. If you are pregnant, talk with your doctor about whether brewer’s yeast could be an appropriate addition to your diet.

Brewer’s yeast is full of folate, which is required for a healthy pregnancy and birth. On the other hand, the security profile of brewer’s yeast during pregnancy has not been studied.

12) Aging

Nicotinamide riboside (that can be found in brewer’s yeast) prolonged the lifespan of yeast by increasing NAD synthesis and sirtuin activity.

It also promoted longevity in mice by enhancing mitochondrial function. Mitochondrial dysfunction is an integral component of aging.

All these effects have not yet been analyzed in human studies. Much more research will be required to set up a connection between brewer’s yeast and lifespan.

Side Effects & Precautions

This May not be a complete collection of the possible side effects and interactions of brewer’s yeast. Speak with your physician before supplementing to avoid unexpected adverse events.

  • People allergic to candida, mold, or yeasts may react badly to brewer’s yeast.
  • Dietary intake of brewer’s yeast might increase the intensity of Crohn’s disease and celiac disease in patients who have antibodies to S.cerevisiae.
  • Individuals who have kidney stones and gout should avoid brewer’s yeast (because of its high purine content).
  • Brewer’s yeast may worsen symptoms in people with eczema.
  • Some brands of brewer’s yeast contain gluten and must be prevented in celiac disease patients.

Active Yeasts used for fermentation (brewing and baking) have been observed to cause illnesses in people with candida or diminished immune system. On the other hand, supplemental brewer’s yeast contains killed S. cerevisiae with no potential to cause or worsen infections.

Brewer’s yeast might not be safe or suitable for those who have mold allergies, digestive ailments, kidney stones, gout, eczema, and celiac disease. Talk with your physician to prevent adverse effects.

Medication and Gene Interactions

Brewer’s yeast may interact with diabetes medications and lead to low blood glucose.

Has substantial amounts of tyramine, which may interact with monoamine oxidase inhibitors (MAOIs) and cause very high blood pressure.

Individuals with MTHFR polymorphisms (MTHFR C677T and A1298C) have a reduced ability to process folic acid entirely and consequently should avoid brewer’s yeast fortified with synthetic folic acid.

Individuals with mutations in the Dectin-1, STAT1, STAT3, TLR4, And CARD9 genes may want to prevent brewer’s yeast because these variants are associated with impaired immunity and increased risk of fungal and yeast infections.

Genetic Variations in the mannan-binding lectin (MBL) gene can lead to mannose-binding lectin deficiency, which is associated with higher anti-Saccharomyces cerevisiae antibody(ASCA) amounts in Crohn’s disease patients.

It’s important to speak with your physician before adding brewer’s yeast into your daily diet or nutritional supplement regimen to prevent these or some other unanticipated consequences.

How is Brewer’s Yeast Used

Brewer’s and nutritional yeasts can be found in powder, liquid, or pill form.

Individuals who choose brewer’s yeast as a supplement regularly take one or two tablespoons daily.

The Powder form is usually blended with water. You may also combine it into other beverages, such as juice, or add it to your smoothies. Have in mind that it’ll include a slightly bitter taste to the beverage. Some aren’t fans of this sour aroma, but others love it. It actually comes down to experimentation with the tastes and finding the combination you like best.

Also, Be Certain to check the quality of the powder or tablets You are buying. The powders are generally cheaper, but higher-quality nutritional supplements are less likely to comprise additives or added sugars.


Brewer’s yeast is a nutrient-rich food with a variety of health benefits, such as gut health support and preventing diarrhea.

This Yeast is high in B vitamins, minerals, pre- and enzymes, and other healthy substances that are active. Its characteristic bitter taste may give your juice or smoothies a unique note. Individuals who dislike bitter flavors may not like the flavor of brewer’s yeast.

Notice that a few brewer’s yeast products contain gluten. If you’re allergic to glutenfree, look For fermented Mailbox’s yeast, such as the type increased on beets.
