Why doesn’t GeneWize use the supplement quercertin in their formulas?
In general, they like the clinical information about quercertin and up until recently they were planning on using quercertin in their formulas. However, they removed quercitin due to potential problems with this ingredient (and the FDA) involving its GRAS status (Generally Recognized as Safe). When the FDA finally rules on this ingredient’s status and they see more supporting information regarding its safety, they will consider adding it back in to their formulations where appropriate.
