How long does it take FDA to respond to GRAS Notification?
The FDA responds to GRAS Notifications within 180 days from the date of original filing. However, the Authority also reserves the right to extend the review timeline by 90 days. So the total number of days can be 270. FDA will respond to GRAS notice in one of three ways:
1. FDA has no questions or comments for the notifier and the contents of the GRAS dossier.
2. FDA concludes there isn’t sufficient data or that the data raises potential issues that the substance is safe.
3. The notifier requests the FDA to stop evaluating the GRAS notice.
