Soy Isoflavones Metabolism.

Soy Bean Extract INCI Name Glycine Soja Extract Soy Isoflavones Genistein Daidzein CAS 84776-91-0 Genistein CAS 446-72-0 Daidzein CAS486-66-8 photo picture image The biological effects of soy isoflavones are strongly influenced by their metabolism, which is dependent on the activity of bacteria that colonize the human intestine. For example, the soy isoflavone daidzein may be metabolized to equol, a metabolite that has greater estrogenic activity than daidzein, and to other metabolites that are less estrogenic.

 Studies that measure urinary equol excretion after soy consumption indicate that only about 33% of individuals from Western populations metabolize daidzein to equol. Thus, individual differences in the metabolism of isoflavones could have important implications for the biological activities of these phytoestrogens.

 Soy Bean Isoflavone is called "Phytoestrogen", because its chemical structure is similar to that of the female hormone estrogen. It is considered to act like a weak female hormone in the body.
