Brewer's yeast contains many active ingredients with high nutritional value (vitamins, amino acids and minerals). These characteristics make brewer's yeast an excellent dietary supplement, ideal for strengthening hair and nails. Brewer's yeast is very rich in vitamin B, which promotes the growth of strong nails. This vitamin along with other proteins and minerals such as calcium, iron, folic acid or copper, are those that contribute to the health of the hair to make it look radiant. They also help to stop hair loss and strengthen it. This dietary supplement should not replace a varied and balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. Store in a cool, dry place. Keep out of reach of children.
