Benefits of Brewer’s and Nutritional Yeasts
1) Brewer’s Yeast is Beneficial for Type 2 Diabetes
Brewers yeast is naturally rich in glucose tolerance factor (GTF), a compound that contains a biologically-active form of chromium [R].

GTF decreased blood sugar, triglyceride, and LDL (“bad”) cholesterol levels and increased levels HDL (“good”) cholesterol in diabetic rats and humans with type 2 diabetes [R].

It also prevents kidney and eye damage in diabetic animals [R].

Glucose tolerance factor achieves these effects by mimicking insulin. It can:

activate proteins involved in insulin signaling pathways [R]
enhance glucose transport [R]
promote glycogen storage [R]

Glucose tolerance factor also enhances the activity of insulin by helping it bind to cells [R,R].

2) Brewer’s and Nutritional Yeast Help with Weight Loss
In a study (DB-RCT) of 54 obese men and women, brewer’s yeast reduced body weight and stomach fat without any negative effects on lean body mass [R].

These results coincide with data from previous animal and human studies (DB-RCT) showing decreased body weight and body fat after yeast supplementation [R, R].

Yeast (from S.cerevisiae) reduces the hunger hormone ghrelin in mice, which may partly explain the loss in body weight [R, R].

It also decreases fat production by reducing the activity of liver enzymes required for making fatty acids [R].

In addition, nicotinamide riboside (found in brewer’s and nutritional yeast) increases enzymes involved in fat burning (sirtuins) and energy usage, thereby increasing weight loss [R].

3) Brewer’s and Nutritional Yeasts May Prevent Heart Disease

A diet rich in brewer’s or nutritional yeasts may lower the risk of heart disease by improving cholesterol and blood pressure levels [R, R, R].

Brewer’s and nutritional yeasts contain many cholesterol-lowering vitamins and minerals:

Beta-glucans [R]
Niacin (which also increases HDL levels) [R]
Nicotinamide riboside [R]
Glucose tolerance factor (only in Brewer’s yeast) [R]
Consuming brewer’s yeast daily lowered LDL cholesterol and triglyceride levels and increased HDL cholesterol in type 2 diabetic patients with high blood cholesterol [R].

Aside from lowering cholesterol, brewer’s yeast also reduces blood pressure. One study (DB-RCT) in 90 adults with type 2 diabetes found that brewer’s yeast significantly lowered both diastolic and systolic blood pressure [R].

The high amounts of potassium, magnesium, and calcium in brewer’s and nutritional yeasts may explain this reduction in blood pressure. According to some studies, a greater intake of these minerals can reduce the risk of high blood pressure, heart disease, and stroke [R, R].

Brewer’s and nutritional yeasts also contain proteins that help decrease blood pressure by decreasing the activity of angiotensin-converting enzyme (ACE). A higher activity of this enzyme is linked to high blood pressure [R, R, R].

4) Brewer’s and Nutritional Yeasts are Good for the Gut
S. cerevisiae helps promote optimal gut function by:

Clearing away bad bacteria while supporting good bacteria [R, R, R, R, R, R]
Preventing harmful bacteria and fungal toxins from sticking to the intestines [R, R, R, R, R]
Aiding nutrient absorption by increasing gut surface area [R, R]
Breaking down phytate, which increases the absorption of minerals like iron, zinc, calcium, and magnesium [R, R, R]
Preserving gut barrier integrity [R, R, R]
Decreasing inflammation [R]
Fighting infections [R]
Many of these effects are mediated by the presence of prebiotics and probiotics in S.cerevisiae (i.e. beta-glucans and mannan oligosaccharides as well as nucleotides [R, R, R].

Because of this, S.cerevisiae may help treat some gut diseases.Brewer’s yeast improved the outcome of C. difficile-associated diarrhea in animals and humans [R, R].

S.cerevisiae also eased stomach pain and discomfort in patients with irritable bowel syndrome (IBS) disease in one study (DB-RCT) [R].

However, Saccharomyces boulardii is the only variant of S. cerevisiae currently approved for probiotic use in humans because of its clinical effectiveness in treating diarrhea and other gut disorders [R, R].

5) Brewer’s and Nutritional Yeast Boost the Immune System
Beta-glucans (sugars found in the cell walls of yeast, bacteria, and fungi) can activate the immune system and boost immune response [R].

These sugars enhance the function of the main cells in the innate immune system including macrophages, neutrophils, and natural killer cells [R].

Beta-glucans bind to specific receptors on these cells, initiating a wide variety of beneficial immune responses (e.g., anti-inflammatory cytokine production) [R].

However, not all beta-glucans are equal. Beta-glucans derived from different sources have unique structures that result in different effects [R].

Research indicates that beta glucans from yeast (i.e., beta-1–3-glucan) have the greatest capacity to activate the immune system [R].

Beta-glucans derived from S.cerevisiae have shown promising results including:

Reduced incidence of bacterial, viral, and fungal infection in mice and humans [R, R, R, R]
Decreased allergy symptoms in mice and humans [R, R, R]
Reduced occurrence of post-operative infection in animals and humans [R]
Decreased inflammation and faster wound healing in animals and humans [R, R, R]
Reduced rate of cancer tumor size and growth in animals [R]
Increased regeneration of white blood cells after radiation in mice [R]
Decreased inflammation in mouse models of arthritis [R]
6) Brewer’s and Nutritional Yeasts have Anti-Cancer Effects
Brewer’s and nutritional yeasts contain ergosterol, a compound that inhibits the growth of human breast cancer cells [R].

One study found that S.cerevisiae killed breast cancer cells by causing programmed cell death (apoptosis) [R].

Brewer’s and nutritional yeasts are excellent sources of selenium, a mineral that has anti-cancer effects [R].

7) Brewer’s and Nutritional Yeasts May Enhance Energy Levels and Improve Mood
S.cerevisiae is a natural dietary source of nucleotides. Nucleotides enhanced endurance and post workout recovery in athletes (DB-RCT), indicating that brewer’s and nutritional yeast may be used to reduce fatigue [R, R].

Patients with chronic fatigue syndrome are often deficient in many nutrients, which can worsen symptoms. A nutritional supplement based on brewer’s yeast (Nagipol) improved cognitive function and mood in chronic fatigue syndrome patients. These effects suggest that brewer’s yeast may be a useful treatment for this disorder [R, R].

Brewer’s and nutritional yeast contains lithium, an element traditionally used to treat mood disorders. Naturally lithium-rich brewer’s yeast improved mood in former drug users (DB-RCT) [R].

8) Brewer’s and Nutritional Yeasts May Promote Healthy Skin
Cosmetic products containing S.cerevisiae extract improved skin moisture, brightness, and smoothness in volunteers [R].

These effects likely stem from the abundant amount of proteins, beta-glucans, vitamins and minerals in S.cerevisiae that have wound healing, hydrating, and antioxidant properties [R, R, R].

9) Brewer’s and Nutritional Yeasts May Improve Brain Health and Cognitive Function
Brewer’s and nutritional yeast are natural sources of nicotinamide riboside, a form of vitamin B3 that is a precursor to nicotinamide adenine dinucleotide (NAD) [R].

Nicotinamide riboside can safely raise levels of NAD in animals and humans [R].

Higher levels of NAD protect nerve cells and may prevent neurodegenerative disease [R, R].

Increasing NAD levels with nicotinamide riboside restored cognitive function in a mouse model of Alzheimer’s disease [R].

In addition, nicotinamide riboside slowed axonal degeneration in cells by stimulating NAD pathways. Preventing axonal damage can help preserve brain cells after injury [R].

10) Brewer’s and Nutritional Yeast May Protect Against Hearing Loss

Nicotinamide riboside, a form of vitamin B3 found in brewer’s and nutritional yeasts, prevented noise-induced hearing loss in mice. It reduced nerve cell damage caused by noise exposure [R].

11) Brewer’s and Nutritional Yeasts May Promote a Healthy Pregnancy
S.cerevisiae is a rich dietary source of folate, a vitamin that helps prevent major birth defects [R, R].

Oxidative stress is a major factor in preeclampsia, a pregnancy disorder that results in complications to the mother and fetus. S. cerevisiae reduced oxidative stress in maternal cord red blood cells, indicating that it may be useful in reducing oxidative damage to the pre-eclamptic fetus [R, R].

12) Brewer’s Yeast Alleviates Premenstrual Syndrome
Brewer’s yeast in combination with vitamins and minerals relieved premenstrual pain in 40 patients with mild to moderate premenstrual syndrome [R].

13) Brewer’s and Nutritional Yeast Have Anti-Aging Properties
Nicotinamide riboside (which is found in brewer’s and nutritional yeast) extended the lifespan of yeast by increasing NAD synthesis and sirtuin activity [R].

It also promoted longevity in mice by improving mitochondrial function. Mitochondrial dysfunction is a key component in aging [R, R].

14) Brewer’s and Nutritional Yeasts May Improve Thyroid Function
Brewer’s and nutritional yeasts are good sources of selenium, a mineral essential for thyroid gland function and thyroid hormone production. Selenium supplementation decreases anti-thyroid antibody levels in patients with Hashimoto’s disease [R, R, R].

Selenium treatment also restores thyroid gland function in Grave’s disease patients [R, R].

15) Brewer’s and Nutritional Yeasts May Promote Fertility
Brewer’s and nutritional yeast contain zinc, a mineral critical for male reproductive health. Increasing zinc levels in infertile men improves sperm count, quality of sperm, and male fertility [R, R].
