Isoflavone Impurities refer to the presence of unwanted or undesired substances in isoflavone extracts. These impurities may result from various sources such as incomplete purification, contamination during processing, or degradation of the isoflavones themselves. The presence of impurities in isoflavones can affect their quality, efficacy, and safety, and therefore, it is important to ensure their removal or reduction during the extraction and purification process.
