Isoflavone

Isoflavones are a type of naturally occurring isoflavonoids, many of which act as phytoestrogens in mammals. Isoflavones are produced almost exclusively by the members of the bean family, Fabaceae.

Chemical structure

Isoflavones have a similar chemical structure to our body's own estrogen, and can bind to the same receptors as the natural hormone. This can either have weak estrogenic effects or block the effects of estrogen, depending on the circumstance.

Dietary sources

Isoflavones are found in high amounts in soy and soy products. Other sources include chickpeas, fava beans, pistachios, peanuts, and other fruits and nuts.

Health effects

Isoflavones have been studied for their potential health benefits, including their potential to reduce the risk of heart disease and breast cancer. However, the evidence is not conclusive and more research is needed.
