Daidzein

Daidzein structurally belongs to the group of isoflavones.

Daidzein can be found in food such assoybeans and soy products like tofu and textured vegetable protein. Soyisoflavones are a group of compounds found in and isolated from the soybean. Ofnote, total isoflavones in soy beans are—in general—37 percent daidzein, 57percent genistein and 6 percent glycitein, according to USDA data. Soy germcontains 41.7 percent daidzein.

Scientific studies of daidzein's antioxidantabilities have given contradictory results: some studies have shown antioxidantproperties in laboratory experiments on cells, but in other experimentsdaidzein has caused oxidative stress on cells.
