Isoflavones are naturally occurring compounds found predominantly in soybeans and other legumes. They belong to a class of phytoestrogens—plant-derived compounds with a chemical structure similar to human estrogen but with much weaker effects. Despite their structural similarity, extensive research has shown that isoflavones do not increase estrogen levels in humans nor do they adversely affect hormone balance. In fact, regular consumption of isoflavone-rich foods like soy has been associated with various health benefits, including a reduced risk of certain cancers, improved heart health, and alleviation of menopausal symptoms.
