Is NMN legal to sell as a supplement?

NMN has had an unusually bumpy regulatory history in the United States, which is worth understanding before you buy.

The short version

• The FDA signalled it did not consider NMN a lawful dietary-supplement ingredient, after it had been studied as a drug.
• The supplement industry (e.g. the NPA) pushed back legally, and the dispute has played out through filings and rulings.
• In practice, NMN remains widely available from many sellers, and community threads track the legal back-and-forth closely.

Because the situation can shift, two practical takeaways: buy from brands that are transparent about sourcing and testing, and if regulatory status genuinely matters to you, check the latest before purchasing. This is general information, not legal advice.
