Research & Evidence
Lariciresinol is a plant lignan present in a wide variety of seeds, grains, vegetables and other plant foods. Together with related dietary lignans such as secoisolariciresinol, it is metabolized by the gut microbiota into the “mammalian lignans” enterolactone and enterodiol, which have weak estrogen-like activity. For this reason lariciresinol contributes to the lignan content used when assessing phytoestrogen intake from the diet. Specific human health effects of lariciresinol alone are not well established.
Toxicity & Safety
As a normal component of a plant-based diet, lariciresinol is regarded as low in toxicity at the levels found in foods. It has not been characterized in detail as an isolated supplement.
