Dihydrodaidzein is primarily used in the field of nutrition and health supplements due to its potential bioactive properties. It is often studied for its role as a metabolite of daidzein, which is a compound found in soy products. Research suggests that it may contribute to the health benefits associated with soy consumption, including supporting bone health and reducing the risk of certain chronic diseases. Additionally, it is being explored for its antioxidant properties and its potential to support cardiovascular health. In the cosmetic industry, dihydrodaidzein is sometimes included in formulations aimed at promoting skin health and reducing signs of aging due to its potential to protect against oxidative stress. Its applications are still under investigation, with ongoing research to better understand its full range of benefits and mechanisms of action.
