Rating (out of 5): 4

Soybean is used to support the hormone system, particularly in relation to estrogenic activity, because it is a rich source of isoflavones—phytoestrogens that can bind to estrogen receptors in the human body. Numerous scientific studies have examined the effects of soybean isoflavones (such as genistein and daidzein) on hormone-related processes. For example, research shows that isoflavones may help alleviate menopausal symptoms like hot flashes and may contribute to bone health by mimicking some effects of estrogen. Clinical trials and meta-analyses suggest that regular consumption of soy isoflavones can modestly reduce the frequency and severity of menopausal symptoms in women. Additionally, there is evidence that soy intake may impact cholesterol metabolism and cardiovascular health, in part due to its influence on hormonal pathways.

However, the estrogenic effects of soy are weaker than those of endogenous estrogen, and the impact can vary depending on individual metabolism and gut microbiota. While there are some concerns about soy consumption in individuals with hormone-sensitive conditions, the majority of research indicates that moderate soy intake is safe and may be beneficial for hormonal health, especially during menopause. Therefore, the use of soybean to support the hormone system is supported by scientific evidence, particularly regarding menopausal symptom relief and moderate estrogenic activity.
