Biotin is contained in various
food products, but little is
known about it. Recently, biotin
has been found to be greatly
involved in our health. In this
report, we will discuss the role
of biotin in a living body,
particularly, the involvement of
biotin in dermatopathies, such
as atopic dermatitis, which is
attracting great attention in
recent years. Furthermore,
since biotin will soon be
approved as a food additive, we
will introduce the importance of
biotin as a dietary supplement.
