Patient Education

Biotin


What is it? Biotin (vitamin B7) is a vitamin found in foods like eggs, milk, and bananas. Biotin deficiency can cause thinning of the hair and a rash on the face.

Biotin is an important part of enzymes in the body that break down substances like fats, carbohydrates, and others. There isn't a good test for detecting low biotin levels, so it's usually identified by its symptoms, which include thinning hair and red scaly rash around the eyes, nose, and mouth.

Biotin is used for biotin deficiency. It is also commonly used for hair loss, brittle nails, and other conditions, but there is no good scientific evidence to support these uses. Biotin supplements might interfere with some lab tests. Talk with your doctor if you are taking biotin supplements and need to have any blood tests.
