Brewer's yeast is used for its high nutritional value; it is rich in proteins (50%), carbohydrates (35%), minerals (10%), and B-complex vitamins. First, the proteins it contains are of high biological value. It provides both essential and some non-essential amino acids. For example, the aspartic acid content helps protect the liver from possible intoxications, particularly from ammonic derivatives. Second, the carbohydrates it contains are compounds, that is, polysaccharides, some of them fibers (cellulose) and other carbohydrates with slow absorption, which means sustained energy without an increase in the glycemic index. Third, in minerals, the potassium and phosphorus content is important, and to a lesser extent, magnesium, selenium, calcium, and manganese. Finally, brewer's yeast contains significant amounts of B-complex vitamins, particularly B1 (thiamine). Dosage: It is recommended to take 4 to 5 tablets a day, between meals. Ingredients: Per 1 tablet: Brewer's yeast 485.5 mg (Saccharomyces cerevisiae), anti-caking agents: silicon dioxide (E-551) and magnesium stearate (E-470b).
