About Daidzein

Isoflavone

Daidzein is an isoflavone found alongside genistein in soya-based foods. It can be converted by gut bacteria to equol, which may enhance its biological activity. It has phyto-oestrogenic properties and is associated with modest benefits for menopausal symptoms in some studies.

⚠️ Too little

No deficiency disease; not an essential nutrient.

🚫 Too much

Intakes from food are considered safe for most people. High-dose supplements are not recommended without medical advice during pregnancy or for hormone-sensitive conditions.
