ABSTRACT

Lignans are plant-derived biphenolic compounds with multiple hydroxyl groups, which, upon ingestion, are metabolized by gut microbiota into enterolignans—enterolactone and enterodiol. These mammalian metabolites exhibit structural similarity to estradiol, enabling lignans to modulate hormonal balance and exert estrogen-like effects. A growing body of evidence highlights their broad spectrum of health-promoting properties, including antioxidant, anti-inflammatory, and hormone-regulating effects. Lignans have shown potential in alleviating menopausal symptoms, preventing estrogen-dependent cancers, and mitigating conditions such as cardiovascular disease, diabetes, and metabolic syndrome. Additionally, their antimicrobial activity against bacteria, fungi, and viruses is being increasingly recognized. This review provides a comprehensive and up-to-date synthesis of current knowledge. It uniquely integrates the latest insights into lignan biosynthesis, gut microbiota-mediated metabolism, and clinically relevant outcomes. Importantly, this review incorporates recent findings from prospective cohort studies and meta-analyses and sheds light on emerging therapeutic applications, including antifungal activity—an area rarely covered in earlier literature. By presenting a holistic perspective, this review advances our understanding of lignans as multifaceted compounds with significant potential in preventive and therapeutic health strategies.
