Research & Evidence
Genistin is the 7-O-glucoside of genistein and one of the common storage forms in which soy isoflavones occur in legumes. After ingestion, the sugar is cleaved by gut enzymes and microbiota to release the aglycone genistein, which is the more biologically active form. It is therefore studied largely as a dietary precursor to genistein.
Toxicity & Safety
As a normal constituent of soy and related foods, genistin is considered well tolerated at dietary levels. Its hormonal activity derives mainly from the genistein released after digestion.
