Isoflavone supplements are a type of dietary supplement that contain compounds found in soybeans and other legumes. These supplements are marketed as a natural way to support women's health, particularly during menopause, due to their ability to mimic the effects of estrogen in the body. Isoflavones have also been studied for their potential to improve bone density and reduce the risk of heart disease. While more research is needed to fully understand their benefits, isoflavone supplements are a popular choice for those looking to improve their overall health and wellbeing.
