Your Guide to GRAS & NDIN Compliance for Ingredients

Expanding into the U.S. ingredient market can feel overwhelming, with strict FDA rules to follow. That’s why we offer support with GRAS notices, self‑affirmed GRAS reviews, and NDI notifications. From identifying the right pathway to preparing submissions, we’re here to ease the process and help you move forward with your ingredient launch. 

Why Ingredient Compliance Matters

ChatGPT said:

Launching an ingredient in the U.S. offers great opportunities but requires meeting FDA expectations. GRAS (Generally Recognized as Safe) applies to food ingredients proven safe through expert review, while NDIN (New Dietary Ingredient Notification) is needed for dietary ingredients not sold before October 15, 1994.

Both demand solid documentation and planning. With the right approach, compliance enables faster approvals, smoother market entry, and stronger trust with regulators and partners. Our team helps you meet requirements, avoid pitfalls, and move forward confidently.
