Brewer's Yeast

Dry brewer's yeast is a unique and natural product that is rich in protein, minerals, and B group vitamins.

100 grams of dry yeast contain 40-48 grams of complete, quality protein, enriched with group B vitamins and microelements, about 2 grams of fat and about 38-52 grams of carbohydrates.


Yeast proteins consist of 16 different amino acids. Composition of brewer's yeast proteins is very similar to animal proteins, which are easily taken up by the body and are of good quality. They are well-absorbed and can be used for eliminating eating disorders caused by protein deficiency or the need of intensive growth.


Vitamins which are in dry bewer's yeast strengthen the body and protect against diseases. These vitamins are not produced by organism, so they must come with the food.


100 g of brewer's yeast contains following B vitamins:

Vitamin B1 plays an important role in the metabolism of carbohydrates and proteins to produce energy for the body. Because the heart, brain and nervous system all require high levels of energy for proper functioning, vitamin B1 is essential for the health of these body systems. Vitamin B1 helps the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy, also helps the body metabolize fats and protein. B1 is needed for healthy skin, hair, eyes, and liver, also helps the nervous system function properly, and is needed for good brain function. A deficiency of Vitamin B1 will result in beriberi, and minor deficiencies may be indicated with extreme fatigue, irritability, constipation, edema and an enlarged liver. Forgetfulness, gastrointestinal disturbances, heart changes, irritability, labored breathing and loss of appetite may also be experienced.


Vitamin B2 is required by the body to use oxygen and the metabolism of amino acids, fatty acids, and carbohydrates. It is further needed to activate vitamin B6, helps to create niacin and assists the adrenal gland. It eases watery eye fatigue and may be helpful in the prevention and treatment of cataracts. Vitamin B2 is required for the health of the mucus membranes in the digestive tract and helps with the absorption of iron and vitamin B6. Although it is needed for periods of rapid growth, it is also needed when protein intake is high, and is most beneficial to the skin, hair and nails. A shortage of this vitamin may manifest itself as cracks and sores at the corners of the mouth, eye disorders, inflammation of the mouth and tongue, and skin lesions. Dermatitis, dizziness, hair loss, insomnia, light sensitivity, poor digestion, retarded growth, and slow mental responses have also been reported. Burning feet can also be indicative of a shortage. Vitamin B2 is a water-soluble vitamin, one that cannot be stored by the body except in insignificant amounts. It must be replenished daily.


Vitamin B6 helps the body to make antibodies which are needed to fight many diseases. It maintains normal nerve function, makes hemoglobin which carries oxygen in the red blood cells to the tissues. Much of the body's chemistry depends upon enzymes which are proteins that help chemical reactions take place. Because vitamin B6 is involved with more than 100 enzymatic reactions, its function in the body is diverse and far-reaching. Vitamin B6 helps the body make several neurotransmitters, chemicals that carry signals from one nerve cell to another. It is needed for normal brain development and function, and helps the body make the hormones. Vitamin B6 deficiency symptoms – irritability, nervousness and insomnia as well as general weakness, skin changes such as dermatitis and acne as well asthma and allergies might develop when pyridoxine is in short supply. Symptoms may include nails that are ridged, an inflamed tongue as well as changes to your bones - which can include osteoporosis and arthritis. Kidney stones may also appear.


Vitamin B3 is required for cell respiration, helps in the release of energy and metabolism of carbohydrates, fats, and proteins, proper circulation and healthy skin, functioning of the nervous system, and normal secretion of bile and stomach fluids. It is used in the synthesis of sex hormones, treating schizophrenia and other mental illnesses, and a memory-enhancer. A shortage of niacin may be indicated with symptoms such as canker sores, depression, diarrhea, dizziness, fatigue, halitosis, headaches, indigestion, insomnia, limb pains, loss of appetite, low blood sugar, muscular weakness, skin eruptions, and inflammation.


Vitamin B5 plays an important role in the secretion of hormones, such as cortisone because of the role it plays in supporting the adrenal gland. These hormones assist the metabolism, help to fight allergies and are beneficial in the maintenance of healthy skin, muscles and nerves. Pantothenic acid is also used in the release of energy as well as the metabolism of fat, protein and carbohydrates. It is used in the creation of lipids, neurotransmitters, steroid hormones and hemoglobin. With Vitamin B5 in short supply symptoms like fatigue, headaches, nausea, tingling in the hands, depression, personality changes and cardiac instability have been reported. Deficiency symptoms – frequent infection, fatigue, abdominal pains, sleep disturbances and neurological disorders including numbness, paresthesia (abnormal sensation such as "burning feet" syndrome), muscle weakness and cramps are also possible indications that this nutrient is in short supply. Biochemical changes include increased insulin sensitivity, lowered blood cholesterol, decreased serum potassium, and failure of adrenocorticotropin to induce eosinopenia.


Vitamin B9 is required for DNA synthesis and cell growth and is important for red blood cell formation, energy production as well as the forming of amino acids. It is essential for creating heme, the iron containing substance in hemoglobin, crucial for oxygen transport. It is important for healthy cell division and replication, since its involvement as coenzyme for RNA and DNA synthesis. It is also required for protein metabolism and in treating folic acid anemia. Vitamin B9 also assists in digestion, and the nervous system, and works at improving mental as well as emotional health. Shortage of B9 may be indicated with diarrhea, heartburn and constipation. It is very important in the development of the nervous system of a developing fetus. Long term deficiency may result in anemia and later in osteoporosis, as well as cancer of the bowel and cervix.


Vitamin B7 (H) is used in cell growth, the production of fatty acids, metabolism of fats, and proteins. It plays a role in the process when energy is released from food. It is also indicated for healthy hair and skin, healthy sweat glands, nerve tissue, and bone marrow, and assisting with muscle pain. Vitamin B7 not only assists in various metabolic chemical conversions, but also helps with the transfer of carbon dioxide. It is also helpful in maintaining a steady blood sugar level. A shortage of Vitamin B7 is very rare, it can happen and may result in dry scaly skin, fatigue, loss of appetite, nausea and vomiting, mental depression as well as tongue inflammation and high cholesterol.


Yeast proteins consist of 16 different amino acids. Quantities of beer yeast proteins are as follows:


Amino acids

Quantity g/kg


































Controlled intake of amino acids stimulates the hormonal system, promotes growth. During intense workouts amino acids are used for production of energy. After a workout the body is trying to recover these losses by increasing protein synthesis.


Brewer’s yeast is found in various trace elements. Each trace has its own function: one is influencing height, another helps nerve impulses to pass, and others perform the function of building materials in the body. So, due to its unique composition, brewer's yeast is a valuable supplement to diet, suitable not only for healthy, but also to sick.


Dry brewer's yeast is particularly valuable because it doesn’t have live yeast cell, has a long shelf life, is convenient to transport.
