Serum Isoflavone Levels in Phytoestrogen-rich (Phyto-600) vs. Phytoesterogen-low (Phyto-Free) Fed Male Rats at 75-Days of Age. For each phytoestrogen measured the Phyto-600 animals displayed significantly higher (** p < 0.01) isoflavone levels compared to Phyto-free fed rats. ODMA = O-desmethylangolensin. Equol levels in Phyto-600 animals accounted for approximately 78% of the total phytoestrogen levels.
