Daidzein is widely used in the health and wellness industry due to its potential benefits as a phytoestrogen. It is commonly incorporated into dietary supplements aimed at supporting hormonal balance, particularly in women experiencing menopause. Its estrogen-like properties help alleviate symptoms such as hot flashes and bone density loss. Additionally, daidzein is studied for its antioxidant and anti-inflammatory effects, making it a component in formulations targeting cardiovascular health and skin care. In the food industry, it is sometimes added to functional foods and beverages to enhance their nutritional profile. Research also explores its role in cancer prevention, particularly in hormone-related cancers, due to its ability to modulate cell growth and apoptosis.
