Hello and hope you are doing well.

Quercetin does not appear to be FDA approved. FDA (Food and Drug Administration) is the controlling authority for all medications. If you see all the OTC's and some herbal medications will not have their approval. This is important because, it means that no scientific studies have been conducted for these medications hence interaction with other medications or their side effects would not have been studied. Hence it is difficult to comment on its effectiveness.

Warm regards.
