Used in dietary supplements for its antioxidant properties, supporting hormonal balance and menopausal symptom relief. Found in plant-based extracts, particularly in flaxseed and sesame seeds, it acts as a phytoestrogen that may help reduce the risk of hormone-related conditions. Also studied for potential benefits in cardiovascular health and cancer prevention due to its ability to modulate estrogenic activity and inhibit certain enzymes involved in hormone metabolism.
