Equol is a non-steroidal estrogen-like compound produced by the intestinal bacterial metabolism of daidzein, a type of isoflavone found in soybeans and soy products. It is noteworthy for its potent ability to bind to estrogen receptors, particularly estrogen receptor beta, exhibiting both estrogenic and anti-estrogenic activities depending on tissue type. Equol has attracted significant research interest due to its potential health benefits, including relief of menopausal symptoms, support for bone health, improvement of skin aging, and possible protective effects against hormone-related conditions.
