Are the isoflavones contained in soy as beneficial as red clover isoflavones from Novogen?
Although much literature indicates that soybeans may contain the highest levels of isoflavones of any plant, soybeans do not contain all four isoflavone groups. Soy contains only the two isoflavones daidzein and genistein. Novogen research suggests that red clover may contain 10 to 20 times the isoflavones found in soy.
