Soy isoflavones are a group of naturally occurring plant compounds found predominantly in soybeans. They are a type of phytoestrogen, which means they have a chemical structure similar to the human hormone estrogen. Due to this similarity, soy isoflavones can interact with estrogen receptors in the body, influencing a variety of physiological processes. One of the areas where soy isoflavones have shown potential benefits is in bone health, particularly in the stimulation of osteoblasts.
