NDIN stands for New Dietary Ingredient Notification while GRAS stands for Generally Recognized as Safe. NDIN and GRAS designations are crucial because they ensure the safety of dietary supplements and food ingredients in the United States. Compliance with NDIN/GRAS (US/US FDA) regulations help food enterprises demonstrate the safety of their products to Regulatory authorities and consumers, building trust and confidence in the marketplace.

NDIN and GRAS (US/US FDA) – An Overview

For companies planning to market a dietary supplement or supply a new ingredient to the United States (US), it is important to determine when a New Dietary Ingredient Notification (NDIN) is required, along with what type of information is required to support a successful notification to the United States Food and Drug Administration (US FDA). In the US, food ingredients are considered either food additives or are Generally Recognized as Safe (GRAS) for explicit uses. An NDIN must be submitted to the US FDA for a dietary ingredient that had not been marketed in the US as a dietary supplement before October 15, 1994.

The significant distinction between a food additive and GRAS is the involvement of the US FDA, which is required for assessing the safety of food additives. There are two separate routes for getting GRAS acknowledgment: a GRAS notification submission to the US FDA and/or a self-GRAS determination or independent GRAS determination. To establish this recognition, a comprehensive safety assessment is required.
