Is NMN legal? Yes, as of September 29, 2025, the FDA has officially reversed its decision to ban NMN (Nicotinamide Mononucleotide). 

‍

The NMN FDA ban was initially put in place because NMN was being investigated as a new pharmaceutical drug, preventing it from being an allowable dietary supplement.

Frequently Asked Questions 

What is the controversy with NMN?

The NMN FDA ban caused controversy because it put the ingredient into a legal gray zone. 

‍

It’s important to note that NMN wasn’t banned due to safety concerns. NMN was excluded from the supplement market because of a “drug preclusion” clause in the Federal Food, Drug, and Cosmetic Act (FD&C Act).

‍

Why was NMN banned?

The NMN supplement was banned because ingredients can’t be marketed and sold as dietary supplements if they’re being investigated as pharmaceutical drugs. 

‍

Is NMN safe?

Yes, studies have shown that oral doses of up to 500 mg of NMN are safe and well-tolerated. It’s best to consult with a healthcare professional if you have any concerns.

‍

What are the benefits of NMN?

NMN is a precursor to NAD+ (nicotinamide adenine dinucleotide), which is a coenzyme that exists in all living cells. NAD+ plays an essential role in cellular metabolism and many other biological processes. As we age, NAD+ levels decrease. 

‍

NAD+ can’t be taken in its original form because it's poorly absorbed. When taken orally, NMN is synthesized into NAD+. 

‍

Simply put, taking NMN replenishes and boosts your NAD+ levels, supporting cell health and longevity.
