What is the NDC Number for Dietary Supplements?

2 min read

The FDA reports that, unlike pharmaceuticals, dietary supplements are regulated as food products, meaning they are not assigned a National Drug Code (NDC). This fundamental distinction means that consumers should not expect to find an NDC number for dietary supplements, as it is a unique identifier reserved exclusively for drugs in the United States.

Quick Summary

This article clarifies why dietary supplements do not have a National Drug Code (NDC), explaining that this unique identifier is for drugs only. It details the separate regulatory pathways for supplements and drugs under the FDA, highlighting the key labeling and approval differences consumers need to know.

Key Points

  • No NDC for Supplements: Dietary supplements are not assigned a National Drug Code (NDC) because this unique identifier is reserved for human drugs in the United States.

  • Different Regulatory Paths: The FDA regulates dietary supplements as a category of food under DSHEA, while drugs are regulated under a separate, stricter process.

  • No Pre-Market Approval: Unlike drugs, dietary supplements do not require FDA approval for safety and effectiveness before being marketed.

  • Mandatory Disclaimers: Supplement labels making structure/function claims must include a disclaimer that the FDA has not evaluated the statement and that the product is not intended to treat, cure, or prevent disease.

  • Labeling Requirements: Key information on a supplement label includes the "Supplement Facts" panel, manufacturer contact details, and the net quantity of contents.

  • Third-Party Verification: Independent seals of approval from organizations like USP or NSF indicate that a product has been voluntarily tested for quality and purity, which can help build consumer trust.

  • Printing an NDC is Misbranding: It is illegal and considered misbranding for a manufacturer to print an NDC number on a dietary supplement label.

No NDC for Supplements: The Fundamental Difference

The National Drug Code (NDC) is a specific identifier used by the FDA for human drugs. Dietary supplements, however, are regulated as a category of food, not drugs, under the Dietary Supplement Health and Education Act (DSHEA) of 1994. Consequently, they are not assigned an NDC, and including one on a supplement label is considered misbranding.

Why Dietary Supplements Don't Get NDCs

The primary reason dietary supplements don't have NDCs is their distinct regulatory classification. This results in key differences compared to drugs:

  • Regulatory Classification: Supplements are classified as food; drugs are separate and more strictly regulated.
  • Pre-Market Approval: Drugs require FDA approval for safety and effectiveness before being sold. Supplement manufacturers are responsible for ensuring safety and compliance but do not need prior FDA approval.
  • NDC Assignment: The FDA assigns NDC labeler codes to drug manufacturers and lists drugs in the NDC Directory, not supplements.
  • Labeling Claims: Supplements can make structure/function claims with a specific FDA disclaimer. Drug claims on supplements are prohibited.

Comparing Regulatory Pathways: Supplements vs. Drugs

This table highlights the differences in how dietary supplements and drugs are regulated, explaining the absence of NDCs for supplements:

Feature Dietary Supplements Drugs
FDA Oversight Regulated as a category of food under DSHEA. Regulated under the Federal Food, Drug, and Cosmetic Act.
Pre-Market Approval Not required; manufacturer ensures safety. Required for safety and effectiveness.
Unique Identifier No NDC assigned; printing one is prohibited. Assigned a unique National Drug Code (NDC).
Manufacturing Standards Must adhere to cGMP for supplements. Must adhere to more stringent cGMP for pharmaceuticals.
Labeling Claims Can make structure/function claims with FDA disclaimer. Can make disease claims with FDA approval.
Post-Market Enforcement FDA acts against unsafe products after they are on the market. FDA monitors and enforces safety continuously.

What to Look for on a Dietary Supplement Label

Since an NDC isn't relevant, consumers should examine other label elements. Key features include the Supplement Facts Panel, manufacturer information, and any FDA disclaimers. Third-party certification seals can also indicate testing by independent organizations. Adherence to Good Manufacturing Practices (cGMP) should also be noted.

The Importance of Independent Verification

Because supplements don't undergo pre-market FDA approval, third-party testing offers valuable assurance about product quality, verifying ingredients and checking for contaminants.

Conclusion

The absence of an NDC number on a dietary supplement is normal due to its classification as a food product. Consumers should focus on label information like the "Supplement Facts" panel, manufacturer details, FDA disclaimers, and consider products with third-party verification for quality assurance. Understanding these regulatory distinctions helps consumers make informed choices.

Frequently Asked Questions

An NDC, or National Drug Code, is a unique 10-digit, 3-segment number used by the FDA to identify and track human drug products in the United States.

Dietary supplements do not have an NDC because they are regulated as a category of food under different FDA regulations than drugs, for which the NDC is intended.

No, the FDA does not approve dietary supplements for safety and effectiveness before they are marketed. It is the manufacturer's responsibility to ensure the product is safe and labeled correctly.

Yes, printing an NDC number on a dietary supplement label is prohibited by the FDA and is considered misbranding.

Consumers should look for the 'Supplement Facts' panel, the manufacturer's information, and the correct FDA disclaimers. Third-party certification seals also indicate quality testing.

The FDA regulates dietary supplements primarily through post-market enforcement. This means they can take action against a product that is found to be unsafe, misbranded, or adulterated after it has reached the market.

The Dietary Supplement Health and Education Act (DSHEA) of 1994 is the law that defines dietary supplements and establishes the framework for their regulation under the FDA, classifying them as a subcategory of food.

A third-party seal from organizations like USP or NSF means that an independent group has verified the product's contents match the label and that it is free of harmful contaminants. It does not guarantee the product's effectiveness.
