About GRAS

Navigating the introduction of novel ingredients in the U.S. market involves proper classification—be it as Generally Recognized as Safe (GRAS), or as a New Dietary Ingredient (NDI) or Old Dietary Ingredient (ODI). Our focus here is on our specialized GRAS services, recognizing it as a commonly chosen pathway to market success. However, if your ingredient falls under an NDI or ODI classification, rest assured that dicentra can offer you tailored support and expertise to meet your unique needs.

There are two separate routes for obtaining GRAS recognition: a GRAS Notification submission to the FDA, where the government issues a letter after an assessment, or a Self GRAS Determination where the FDA is not involved and the stakeholder is responsible for verifying safe use with the review of an expert panel.

In either case, the applicant needs to demonstrate that the substance will not cause harm when the ingredient is ingested under the intended use.
