Lignan

Abundant phytoestrogens in flaxseeds and seeds with antioxidant and anti-inflammatory properties.

Definition

Polyphenolic ligands that weakly interact with estrogen receptors, abundant in flaxseeds, whole grains, and dried fruits.

How it works

Lignans are dimeric polyphenolic compounds present naturally in many plants, particularly flaxseeds. These molecules are converted by the intestinal microbiome into enterolignans, which can exert modest phytoestrogenic effects. Lignans also possess strong antioxidant and anti-inflammatory properties. They play a role in cardiovascular, bone, and hormonal health.

Role

Phytoestrogen antioxidant promoting cardiovascular, bone, and hormonal health.

Examples

  • Ground flaxseeds
  • Sesame
  • Dried fruits
  • Pumpkin seeds
  • Whole grains

Recommendations

Consume 1-2 tablespoons of ground flaxseeds daily for optimal lignan intake. Vary seed and dried fruit sources. Drink enough water to facilitate digestion of fiber associated with lignans.

Key takeaway

Lignans from flaxseeds and other natural sources offer antioxidant protection and hormonal benefits through intestinal microbiome action.
