SpectraSoy® features high quality soy concentrate†, which supplies a full spectrum of isoflavones including glucoside and aglycone forms of genistin, daidzin, and glycitin, plus other beneficial compounds naturally found in soybeans and soy foods. Careful extraction techniques ensure that the natural profile and ratios of isoflavones are maintained as they would be found in traditional soy foods. SpectraSoy is so highly concentrated that just one tablet provides 45 mg of isoflavones, an amount similar to the average daily intake in Japan.
