Used in research related to gut microbiota and metabolic health due to its role as a mammalian lignan metabolite. It is studied for potential antioxidant, anti-inflammatory, and hormone-modulating properties. Investigated for possible protective effects in cardiovascular disease, certain cancers (especially hormone-related types like breast and prostate), and menopausal symptoms. Also used as a biomarker for dietary lignan intake and gut microbial activity in nutritional and clinical studies.
