After years of uncertainty and legal disputes, the U.S. Food and Drug Administration (FDA) declared on September 29, 2025, that Beta Nicotinamide Mononucleotide (NMN) can be lawfully marketed as a dietary supplement. This decision comes after consistent pressure from the Natural Products Association (NPA) and years of debate around FDA’s interpretation of the Dietary Supplement Health and Education Act (DSHEA).
For businesses in the supplement industry, this ruling changes the landscape. If you manufacture or market NMN products, you need to understand what this decision means, how it impacts your compliance obligations, and what steps you should take moving forward.
Keep reading to learn how this development may affect your business.
FDA’s Reversal on NMN
The FDA previously attempted to block NMN, claiming it was first investigated as a drug. This triggered a major pushback from NPA, which filed a citizen petition, launched a lawsuit, and mobilized industry stakeholders. In response, the FDA acknowledged evidence showing NMN had been marketed as a dietary supplement in the U.S. as early as 2017. This acknowledgment was critical because it placed NMN within the definition of a dietary supplement under DSHEA.
The official response by FDA highlighted how it interprets the “drug preclusion” clause, which prevents ingredients studied as drugs from later being marketed as supplements if they were not already sold lawfully as supplements. While disagreements remain, the FDA’s latest decision affirms NMN’s place in the supplement market.
Why This Matters for Supplement Businesses
The confirmation that NMN is lawful in dietary supplements brings opportunities but also responsibilities. For example, retailers and e-commerce platforms can once again list NMN products with regulatory assurance. At the same time, businesses now have a clearer path to compliance with reduced risk of enforcement.
However, the FDA did not provide detailed interpretive guidance on exceptions to drug exclusion or what constitutes substantial investigations. This means some regulatory ambiguity remains, and companies must consider potential litigation risks and evolving FDA positions when planning their NMN strategy.
Furthermore, consumers can access NMN supplements knowing they meet FDA’s legal definition. This outcome also mirrors previous cases, such as NAC (N-acetyl-L-cysteine), where industry advocacy influenced FDA’s enforcement approach. Therefore, while the ruling offers clarity, businesses still need tailored compliance strategies to anticipate potential shifts in regulatory expectations.
Legal and Business Risks
Although FDA’s decision provides welcome clarity, several risks remain for companies entering or expanding in the NMN space. The legal environment continues to evolve, and recent court decisions have shown that agency interpretations may face closer judicial scrutiny. This could create uncertainty about whether FDA’s current position will be upheld if challenged.
In addition, future administrations may shift regulatory priorities, potentially reconsidering how NMN is treated under dietary supplement law. Businesses should also be aware of possible private litigation or state-level consumer protection claims, which could argue that NMN products are marketed unlawfully despite FDA’s statement.
These risks underscore the importance of proactive compliance strategies and legal review before bringing products to market.
Compliance Considerations for NMN Products
While NMN is now recognized as lawful in supplements, businesses must still ensure full compliance with FDA regulations. This includes:
- Submitting proper New Dietary Ingredient (NDI) notifications if required.
- Ensuring product labeling meets FDA standards.
- Verifying good manufacturing practices (GMP) are followed.
- Confirming claims made about NMN are structure-function claims and not drug claims.
