About Secoisolariciresinol (SECO)
Lignan
Secoisolariciresinol is the predominant lignan in flaxseeds (linseeds) and is also found in sesame, wholegrains and some vegetables. Gut bacteria convert it to the enterolignans enterodiol and enterolactone, which have weak phyto-oestrogenic activity.
⚠️ Too little
No deficiency disease; not an essential nutrient.
🚫 Too much
No adverse effects established from dietary intakes. Flaxseed is the richest source; raw flaxseed in very large amounts may contain cyanogenic compounds but amounts in normal use are safe.
