Companies intending to market new food ingredients in the United States – whether in conventional foods or dietary supplements – must register their products either through a GRAS (Generally Recognized as Safe) determination or a New Dietary Ingredient Notification (NDIN). It is also legal to use the self-affirmed GRAS route without filing with the FDA. However, GRAS Notices are often submitted to the FDA, primarily at the request of U.S. clients. There is no equivalent self-affirmed registration pathway for NDIs; filing a notification with the FDA is always required.
The US Health Secretary Robert F. Kennedy Jr. has initiated a major regulatory shift by directing the FDA to close the self-affirmed GRAS loophole, aiming for greater transparency and safety in the U.S. food supply.
The process is still in its early stages, with rulemaking and legislative efforts expected to follow. For now, the current GRAS system remains unchanged, but significant reforms can be on the horizon.
In this webinar, you will hear about complex US food regulations and how they can change. You will learn how to choose the correct registration route for your food ingredient, GRAS or NDI. We will also summarise the main requirements of GRAS and NDI registration and highlight the differences.
The webinar is aimed at all interested parties who are planning the US registration for their new food ingredient from startups to SME and big companies.
You will learn:
- How GRAS and NDI registrations work and how they differ
- How to choose the correct registration pathway for your food ingredient or dietary supplement
- What upcoming FDA changes may mean for future US market access
