Think of your new dietary supplement as a house you’re building. You wouldn’t start putting up walls without first pouring a solid foundation. In the world of FDA regulations, that foundation is your safety data. If your product uses a new dietary ingredient—one not on the market before October 1994—you must lay this groundwork through a formal submission. A weak or incomplete file can cause your entire launch plan to crumble. The New Dietary Ingredient Notification Process is your blueprint for building a compliant product. By following it carefully and providing strong evidence, you ensure your business is built to last, avoiding costly delays and regulatory actions down the road.
Key Takeaways
- Build Your Case on Solid Safety Data: Your entire NDIN submission is an argument for your ingredient’s safety. Success depends on providing comprehensive scientific evidence, including detailed identity specifications and a history of safe use, to create a clear and convincing narrative for the FDA.
- Master the Process Through Preparation: The 75-day pre-market notification is a strict deadline. Avoid common delays and objections by gathering all required documentation well in advance, understanding the submission requirements, and being prepared to respond quickly to any FDA feedback.
- Treat Compliance as an Ongoing Commitment: A successful NDIN filing is the beginning, not the end, of your regulatory duties. You must continue to monitor your product’s safety, keep marketing claims consistent with your submission, and stay current with changing FDA guidelines to maintain your product’s standing.
What Is a New Dietary Ingredient (NDI)?
If you’re bringing an innovative dietary supplement to market, understanding the concept of a New Dietary Ingredient (NDI) is your first and most critical step. This classification is central to FDA compliance and determines the regulatory path you’ll need to follow. Getting this right from the start saves you time, money, and major headaches down the road. It’s all about ensuring your product is built on a foundation of safety and regulatory approval.
What It Is and Why It Matters
A “new dietary ingredient” is any dietary ingredient that was not sold in the United States in a dietary supplement before October 15, 1994. Think of this date as a line in the sand. Ingredients on the market before then are generally considered “old” or “grandfathered” in. Anything introduced after that date is an NDI. The reason this matters is simple: safety. The FDA requires manufacturers to demonstrate that any new ingredient is reasonably expected to be safe for consumers under its intended use conditions. This is done through the official New Dietary Ingredient (NDI) Notification Process, which you must complete before your product hits the shelves.
A Quick Look at the DSHEA
The entire framework for NDIs was established by the Dietary Supplement Health and Education Act of 1994 (DSHEA). This landmark legislation created the regulatory system that governs dietary supplements in the U.S. today. DSHEA defined what dietary supplements and dietary ingredients are, and it created the requirement for manufacturers to notify the FDA about any new ingredients. Essentially, DSHEA struck a balance between allowing consumers access to supplements and giving the FDA the authority to oversee the safety of new products entering the market. Understanding DSHEA helps you see that the NDI notification isn’t just arbitrary paperwork—it’s a legal requirement rooted in a foundational law.
How the NDI Notification Process Works
Getting a new dietary ingredient to market involves a specific, mandatory conversation with the FDA. This isn’t just about filling out a form; it’s about presenting a clear, evidence-based case that your ingredient is safe for consumers. The New Dietary Ingredient Notification (NDIN) process is your formal pathway to do this. Think of it as your ingredient’s official introduction to the regulatory world. You must notify the FDA at least 75 days before you plan to start selling your product. This 75-day window gives the agency time to review your safety data and ask any questions. The entire process is designed to protect public health, and getting it right from the start saves you time, money, and major headaches down the road. It requires careful preparation and a deep understanding of what the FDA expects to see in a submission.
The Core Steps for Submission
At its heart, the submission process is straightforward. If you’re a manufacturer or distributor, you must notify the FDA at least 75 days before your supplement containing any “new dietary ingredients” hits the market. A “new dietary ingredient” is defined as any ingredient that wasn’t sold in the U.S. before October 15, 1994. Your notification needs to include comprehensive information about the ingredient, from its name and chemical composition to a detailed description of your manufacturing process. You also have to clearly state how the ingredient will be used in your dietary supplement, including the dosage and serving size.
Do You Need to Submit an NDIN?
This is the first critical question to answer. You are required to submit an NDIN if your dietary supplement contains a new dietary ingredient that has not been present in the food supply as an article used for food in a form in which the food has not been chemically altered. It’s a mouthful, but the distinction is important. If your ingredient is truly new to the U.S. market or has been chemically changed from its natural food state, a notification is almost certainly necessary. Making this determination can be complex, as it often requires historical research and a nuanced understanding of FDA definitions. Getting this step wrong can lead to significant compliance issues later on.
Proving Your Ingredient Is Safe
The most crucial part of your NDIN is demonstrating that your ingredient is reasonably expected to be safe under its proposed conditions of use. The responsibility to provide this proof rests entirely on you, the manufacturer or distributor. Your notification must include a robust history of use or other evidence of safety, which typically means providing scientific studies and data. According to FDA guidance, simply sending abstracts or summaries isn’t enough; you need to include full copies of any published articles or reports that support your safety claims. This evidence forms the backbone of your submission and is what the FDA will scrutinize most closely during its review.
What to Include in Your NDIN Submission
Putting together your New Dietary Ingredient Notification is a bit like building a case. Your goal is to present the FDA with a clear, comprehensive, and convincing argument that your ingredient is safe for consumers. A well-organized submission not only demonstrates your diligence but also makes the review process smoother for everyone involved. The FDA has specific requirements for what this package must contain, so getting the details right from the start is crucial. Let’s break down exactly what you need to include to create a strong and complete submission.
Your Documentation Checklist
Think of your submission as having three core pillars. First, you need to establish the identity of your New Dietary Ingredient (NDI). This includes its name, chemical composition, and characteristics. Second, you must provide a detailed description of the dietary supplement that will contain the NDI, explaining how it will be marketed and used by consumers. Finally, and most importantly, you need to supply the safety data. This is the scientific evidence that forms the basis of your notification, proving your ingredient is reasonably expected to be safe under its intended conditions of use. The FDA provides official guidance on the NDIN process that details these requirements.
Detail Your Formulation and Intended Use
The FDA needs to understand not just what your ingredient is, but how you plan to use it. Your notification must clearly show that the NDI is safe for its specific intended use in your product. This means providing robust scientific evidence, like toxicology studies or other research, that supports your safety claims. You’ll also need to describe the manufacturing process in detail. This isn’t the time to be vague. The FDA’s background for industry explains that this context is essential for their safety assessment. Be prepared to share the ingredient’s name, its properties, and the exact conditions of use, including serving size and daily intake.
How to Protect Your Trade Secrets
It’s completely understandable to be concerned about sharing proprietary information. The good news is that the FDA has a system in place to protect your confidential business information. When you submit your NDIN, the entire file is kept confidential for 90 days after the filing date. After this period, the notification becomes publicly available. However, you can—and should—clearly mark any information that qualifies as a trade secret. The FDA’s NDI notification process allows for these designated sections to be excluded from the public record, protecting your valuable intellectual property while still allowing for regulatory transparency.
What to Expect from the NDIN Timeline
The New Dietary Ingredient Notification (NDIN) process follows a clear, regulated timeline. Knowing the key milestones helps you plan your product launch, manage inventory, and set realistic expectations with your team and investors. While the official review period is 75 days, the entire journey—from preparing your data to responding to potential FDA feedback—takes much longer. Think of it less like a sprint and more like a well-planned expedition where preparation is everything.
The timeline officially begins the moment the FDA receives your submission and logs it into their system. From that day forward, a 75-day clock starts ticking for the agency to review your safety data and ingredient information. During this period, it’s essential to be prepared for potential communication from the FDA. A smooth process depends entirely on the quality and completeness of your initial submission. A well-organized, scientifically sound notification is your best tool for a straightforward review. The FDA provides a detailed overview of the New Dietary Ingredient Notification Process, which is a great resource to keep handy. Partnering with a regulatory expert can help you prepare a thorough submission that anticipates the FDA’s requirements and sets you up for a positive outcome.
Prepare for Your Submission
Your NDIN must be submitted to the FDA at least 75 days before your dietary supplement is introduced onto the US market. This is a strict deadline, not a suggestion. You cannot legally sell your product until this 75-day period has passed and the FDA has not objected to your submission. It’s wise to treat this as the final phase of your pre-market journey. The real work of compiling safety evidence, documenting your manufacturing processes, and writing the notification itself should begin many months earlier. Rushing this stage is a common misstep that can lead to an incomplete file and significant delays.
The 75-Day FDA Review
Once you submit your NDIN, the FDA has 75 days to review it. During this time, the agency evaluates the safety information you’ve provided to determine if the new dietary ingredient is reasonably expected to be safe under its proposed conditions of use. It’s also important to know that your notification is kept confidential for the first 90 days after filing. After that 90-day mark, your submission becomes public, with the exception of any information that is protected as a trade secret. This review period is an active evaluation, so having all your documentation in order from the start is critical for a smooth process.
What Happens After You Submit
Within the 75-day review window, the FDA will send you a response. If your submission is complete and the agency has no safety concerns, you may receive an acknowledgment letter, sometimes called a “good day” letter. However, the FDA may also respond with questions or a request for more information. This is a normal part of the process and an opportunity to clarify your data. If the FDA finds the notification incomplete or has significant safety concerns, it may issue an objection letter. It’s important to understand that if your notification is incomplete, your product is considered adulterated under the law until the issues are resolved.
Avoid These Common NDIN Submission Hurdles
Submitting a New Dietary Ingredient Notification can be a complex process. Even small missteps can lead to delays or objections from the FDA, so knowing the common hurdles is the best way to prepare. Let’s walk through some of the most frequent challenges and how you can get ahead of them.
Gathering the Right Data and Documents
The most common reason for an incomplete NDIN is simply missing information. Your notification needs to tell a clear and complete story about your ingredient’s safety. The FDA requires you to provide the right information about the NDI’s identity, a description of the supplement containing it, and data proving its safety. Think of it as building a case with solid evidence. This means detailed chemical identity specifications, a history of use, and comprehensive toxicological studies. Rushing this step or submitting an incomplete package is the surest way to receive an objection letter.
Handling Complex Regulations
Bringing a new product to market involves more than just the science. Manufacturers often face internal challenges like staffing and external pressures like supply chain disruptions. These factors can complicate your NDIN submission. For instance, a change in suppliers could alter your ingredient’s identity profile, potentially invalidating your safety data. The regulatory landscape doesn’t stand still, so it’s crucial to have a system to manage these variables. A clear regulatory strategy ensures your business operations and compliance efforts are perfectly aligned, preventing these issues from derailing your submission.
How to Respond to FDA Feedback
After you submit your NDIN, the FDA has 75 days to review it and may have questions. It’s important to be prepared to respond promptly and thoroughly, as a slow response can lead to an objection. The goal is to give the FDA the information it needs to feel confident in your ingredient’s safety. It’s also helpful to know that the FDA keeps your notification confidential for 90 days. After that, it becomes public, excluding trade secrets. Understanding this timeline, as detailed in the FDA’s final guidance, helps you protect your intellectual property while engaging with the agency.
How to Set Your NDIN Up for Success
Submitting an NDIN can feel like a final exam, but with the right preparation, you can approach it with confidence. The key is to present a clear and convincing case for your new dietary ingredient. By focusing on quality data, proactive communication, and the right support, you can improve your chances of a smooth review. Let’s walk through three essential strategies to help you succeed.
Provide Thorough Safety Data
Your entire NDIN submission hinges on proving your ingredient is safe for its intended use. The FDA needs a complete picture, so your submission must include robust safety data. This isn’t the place to be vague. You’ll need to provide a detailed identity of your new dietary ingredient, a description of the supplement containing it, and all scientific evidence supporting its safety. The FDA outlines the important aspects of the NDIN process in its guidance, and being thorough here builds a foundation of trust, making it easier for reviewers to give your submission a green light.
Consult with the FDA Early
One of the smartest moves you can make is to engage with the FDA before you submit your notification. The agency encourages manufacturers to seek preliminary feedback, and you should take them up on it. A pre-submission meeting allows you to ask questions, clarify potential issues, and understand the agency’s expectations. This proactive approach helps you spot and fix weaknesses in your submission ahead of time. It shows you’re committed to getting things right and helps align your notification with the FDA’s final guidance, which can streamline the official review.
Work with a Regulatory Expert
You don’t have to go through the NDIN process alone. The regulations are complex, and a single misstep can lead to delays or rejection. Working with a regulatory expert can make all the difference. These professionals live and breathe FDA compliance. They can help you determine if your ingredient qualifies as “new,” develop a strategic plan, and compile your data into a compelling narrative. Experts in NDI compliance ensure your submission is complete and persuasive, giving you peace of mind and a much stronger chance of success.
Stay Compliant After Your NDI Is Filed
Successfully filing your New Dietary Ingredient Notification is a huge milestone, but your work isn’t over just yet. Think of it as getting your driver’s license—you’ve proven you know the rules, and now you have to follow them every day. Maintaining compliance is an ongoing commitment that protects both your customers and your business. After the FDA gives you the green light, your focus should shift to long-term vigilance.
This means you have a continuing responsibility to ensure your product remains safe, your marketing stays honest, and you keep up with any regulatory changes. Failing to do so can lead to warning letters, product recalls, or other enforcement actions that can damage your brand’s reputation. Building a solid post-market compliance plan is just as important as preparing your initial submission. It’s about creating sustainable practices that integrate regulatory awareness into your daily operations, ensuring your product’s success and safety for years to come.
Monitor Your Product’s Safety
Your duty to ensure your product’s safety doesn’t end once it hits the shelves. The evidence of safety you provided in your NDIN was the foundation, but now you must actively monitor your product in the real world. This involves establishing a system for tracking and evaluating any adverse event reports from consumers.
Staying current with scientific literature related to your ingredient is also essential. If new studies emerge that question its safety, you need to be aware of them and prepared to act. This proactive approach not only fulfills your regulatory obligations but also reinforces your brand’s commitment to consumer well-being, building trust and loyalty with your audience.
Keep Your Labels and Marketing Compliant
The claims you make on your product labels and in your marketing materials must be consistent with the information you submitted in your NDIN. The comprehensive information about your ingredient’s identity and intended use sets the boundaries for how you can present it to the public. This means you can’t suddenly start making new health claims that weren’t part of your original safety assessment.
Every piece of marketing copy, from your website to your social media posts, should be reviewed for compliance. The FDA closely monitors how dietary supplements are marketed to ensure companies aren’t misleading consumers. Sticking to your approved claims is the simplest way to stay off the FDA’s radar and maintain your brand’s integrity.
Keep Up with Changing FDA Guidelines
The regulatory world is not static. The FDA periodically updates its guidance and enforcement priorities, and it’s your responsibility to stay informed. What is considered compliant today might change tomorrow, so you need a reliable way to keep track of any new developments. This could involve subscribing to FDA newsletters, participating in industry trade groups, or partnering with regulatory experts.
Having a process to monitor for updates or changes in guidelines ensures you can adapt quickly and avoid falling out of compliance. Being proactive about regulatory intelligence allows you to anticipate shifts and adjust your strategy accordingly, rather than reacting to a warning letter after it’s too late. This foresight is a hallmark of a mature and responsible company.

Frequently Asked Questions
What if my ingredient was sold in the U.S. before October 1994? If you have solid proof that your dietary ingredient was marketed in the United States before that date, it is likely considered a “grandfathered” or “old” dietary ingredient. In that case, you would not need to submit a New Dietary Ingredient Notification. The key here is having strong, verifiable documentation to support that history, as the FDA can ask you to prove its pre-1994 status at any time.
Can I use an ingredient if another company has already filed an NDIN for it? This is a common point of confusion. An NDIN is specific to the ingredient as submitted by the original notifier, including its unique identity, manufacturing process, and intended conditions of use. If you source the same ingredient from a different supplier or plan to use it in a different way, the original notification may not apply to your product. It is highly likely you will need to file your own NDIN to establish the safety of the ingredient as you intend to use it.
Is the 75-day review period a guarantee that my product will be approved? The FDA does not “approve” New Dietary Ingredients in the same way it approves drugs. The 75-day period is the window the agency has to review your safety data. If the FDA does not object to your notification within that time, you can legally market your product. However, this lack of objection is not a formal endorsement. If the agency finds your submission incomplete or has significant safety concerns, it will send an objection letter, and you cannot proceed to market.
What’s the single biggest mistake companies make in their NDIN submissions? The most frequent reason for an objection is providing incomplete or unconvincing safety data. The entire responsibility for proving an ingredient is reasonably expected to be safe rests on the manufacturer. Submitting a notification with weak scientific evidence, missing studies, or a poorly constructed argument about the ingredient’s identity is the fastest way to receive an objection letter from the FDA and cause significant delays.
What happens if I sell a product with a new dietary ingredient without filing a notification? Selling a dietary supplement containing a new dietary ingredient without first submitting the required NDIN is against the law. The FDA considers such a product to be “adulterated.” This can lead to serious consequences, including FDA warning letters, product seizures, import detentions for international goods, and other enforcement actions that can jeopardize your business and brand reputation.
