What is Genistein?
Genistein is a naturally occurring isoflavone — a type of plant-based compound that can bind to estrogen receptors in the body. This unique property allows genistein to mimic some of estrogen’s effects, though more gently, which can help balance hormones naturally.
You’ll find genistein primarily in:
- Soybeans and soy products (tofu, tempeh, soy milk)
- Chickpeas
- Fava beans
- Certain supplements standardized for isoflavone content
