Glycitein
A minor soy isoflavone and phytoestrogen, present in smaller amounts than genistein and daidzein.
Where Does It Come From? (1)
Glycitein is a naturally occurring isoflavone (phytoestrogen), found in Soybean. It is well tolerated orally (low toxicity).
Research & Evidence
Glycitein is one of the three main soy isoflavones, alongside genistein and daidzein, though it is usually present in smaller amounts. It is a methoxylated isoflavone and a weak phytoestrogen, and it makes up a larger proportion of the isoflavones in soy germ. It is studied as part of the overall isoflavone profile of soy rather than as a standalone agent.
Toxicity & Safety
As a normal dietary constituent of soy, glycitein is considered well tolerated. Like the other soy isoflavones it has weak hormonal activity, which is the usual context for any caution.
