From: Soy isoflavones and their metabolites modulate cytokine-induced natural killer cell function

Soy isoflavones and their metabolite compounds. Genistein and daidzein are two of the most abundant isoflavones found in soy. Daidzein can be further metabolized into secondary compounds, O-demthylangolensin (O-DMA) and Equol.
