WHAT IS BIOTIN (B7)

Biotin, also known as vitamin B7 or vitamin H, is a water-soluble vitamin that plays an important role in various bodily functions. It is involved in the metabolism of carbohydrates, fats, and proteins, and is important for the health of the skin, hair, and nails.

Biotin is found in many foods, including eggs, liver, nuts, seeds, and certain vegetables. It can also be taken as a dietary supplement, either alone or as part of a multivitamin.

Deficiency of biotin is rare, but can occur in people who consume large amounts of raw egg whites, which contain a protein called avidin that binds to biotin and prevents its absorption. Symptoms of biotin deficiency may include skin rash, hair loss, and brittle nails.

Biotin supplements are sometimes used for the treatment of various conditions, including hair loss, brittle nails, and skin rash. However, the evidence for the effectiveness of biotin supplementation for these conditions is limited, and it is generally recommended to obtain biotin from a balanced diet rather than relying on supplements.
