Women receiving equol supplement showed improved arterial stiffness and climacteric symptoms. Significant improvement in skin auto-fluorescence and visceral fat area was observed in equol producers.
Almost all participants have equol producing bacteria, however, there are only 20% of equol producers. Equol producing ability is related to gut microflora diversity.

Equol production might not depend on the quantity, but on the quality of equol-producing bacteria. High microbial diversity might enhance equol production. Increasing microbial diversity through healthy lifestyle habits and habitual consumption of a wide variety of foods might be useful to maintain a healthy gut environment for equol production.
