Used in research for its potential neuroprotective and anti-addictive properties, particularly in studies related to alcohol consumption. It acts as a selective inhibitor of aldehyde dehydrogenase 2 (ALDH2), which contributes to the accumulation of acetaldehyde, a toxic byproduct of alcohol metabolism. This effect has made it a subject of interest in developing treatments for alcohol use disorders. Additionally, daidzin exhibits antioxidant and phytoestrogenic activities, supporting its investigation in metabolic and hormonal health. It is also utilized as a natural compound in dietary supplements and functional foods aimed at promoting general wellness.
