Dietary supplement based on brewer's yeast. Brewer's yeast is a microscopic fungus found naturally in the skin of certain fruits and beer wort. It does not produce fermentation, so it is suitable for direct consumption, being also easily digestible and quickly absorbed by the body. It is rich in B vitamins, mineral salts and amino acids. It contains relevant amounts of lysine, threonine and isoleucine, has a significant amount of phosphates and potassium, and being low in sodium is suitable for hypertensive. It helps in skin care (especially indicated in acne), in cases of fragile hair and brittle nails, in situations of fatigue and asthenia, to supplement vegan diets, to regulate bowel function and to strengthen the immune system. * Dietary supplements should not be used as a substitute for a varied and balanced diet.
