Lignans are a type of polyphenolic compound found in various plants, particularly in seeds, whole grains, and vegetables. They are one of the major classes of phytoestrogens, which are plant-derived compounds with estrogenic activity. Lignans are metabolized by the gut microbiota into enterolignans, such as enterodiol and enterolactone, which may have several health benefits, including potential anti-cancer properties.
