Can I Buy NMN in the USA?
Yes, you can still buy NMN in the USA, even though it's not officially recognized as a dietary supplement by the FDA. Many reputable companies continue to sell NMN online and through direct-to-consumer websites.
The FDA's decision hasn't removed NMN from the market entirely. It’s widely available as a “research-use-only” product or sold through companies operating within regulatory gray areas.
You’ll often see NMN labeled carefully to avoid supplement language, but it's still accessible for personal use. Just make sure to buy from trusted sources and check for third-party testing to avoid low-quality or counterfeit products.
What Is NMN and Why Is It So Popular?
NMN, short for Nicotinamide Mononucleotide, is a molecule that your body uses to make NAD+, a compound that helps turn food into energy and supports cellular repair.
Interest in NMN has grown quickly thanks to studies linking it to longevity and age-related health benefits. As NAD+ levels decline with age, many people turn to NMN supplements for support. Here's why it’s so popular:
The FDA’s Stance on NMN: What You Need to Know
As of October 2024, the FDA has paused enforcement of its ban on NMN as a dietary supplement while it reviews a legal petition. During this time, NMN supplements are still being sold, although their regulatory status may change.
The issue began in late 2022, when the FDA stated that NMN could not be sold as a dietary supplement because it was under investigation as a new drug.
This decision came after the agency reviewed notifications tied to MIB-626, a pharmaceutical form of NMN being studied by Metro International Biotech. The FDA concluded that NMN was excluded from the supplement category under existing rules.
Several companies, including Effepharm and SyncoZymes, attempted to submit NMN for approval under the FDA’s New Dietary Ingredient Notification (NDIN) pathway, but were rejected in early 2023.
In response, groups like the Natural Products Association and Alliance for Natural Health challenged the FDA’s position. They filed formal petitions and, in August 2024, launched a federal lawsuit seeking to reinstate NMN as a legal supplement.
Thanks to this legal action, the FDA announced on October 24, 2024, that it would temporarily pause enforcement of its 2022 decision. This means companies can continue selling NMN, provided it would otherwise meet dietary supplement requirements.
While the situation is still evolving, this pause gives consumers and brands some breathing room. Buyers should stay informed, as future rulings may affect how NMN can be marketed and sold in the U.S.

Where Can I Buy NMN in the USA?
You can still buy NMN in the USA through online retailers, direct-to-consumer websites, and some specialty health stores. While large platforms like Amazon have removed most NMN listings, many trusted brands continue to offer it under “research use” or non-supplement labels.
If you’re looking for NMN, here are your best options:
Direct from manufacturers: Many companies sell NMN through their official websites with detailed product info, lab testing, and subscription discounts.
Niche supplement retailers: Sites that cater to biohackers and longevity enthusiasts often carry NMN, including trusted names like Omre, which offers clean, lab-tested formulas designed for cellular health and aging support.
Specialty health stores: Some physical and online stores may stock NMN, but inventory varies based on location and enforcement.
International sellers: Some buyers report ordering NMN from overseas with personal import allowances, though this may involve customs checks.
When shopping, focus on brand transparency, third-party testing, and clear sourcing info. Avoid suspiciously low prices or vague product labels.
How to Buy NMN Safely in the USA
With NMN’s regulatory status in flux, quality control is a top concern. Since it’s not regulated as a dietary supplement, there’s a risk of inconsistent potency or contamination. To buy NMN safely, follow these practical tips:
Research the Brand: Opt for companies with a strong reputation and clear information about their sourcing and production processes.
Look for Third-Party Testing: Reputable sellers provide certificates of analysis from independent labs, verifying the product’s purity and NMN content.
Avoid Bargain Deals: Extremely cheap NMN might be diluted or counterfeit. Quality supplements come at a reasonable cost reflective of production standards.
Check Reviews: Customer feedback can reveal insights about a product’s effectiveness and reliability.
Consult a Professional: Before starting NMN, talk to a doctor or nutritionist, especially if you’re on medication or have health conditions.
Taking these steps ensures you’re getting a legitimate product that aligns with your health goals.
Is NMN Safe to Use?
NMN is generally well-tolerated, with studies suggesting it’s safe at moderate doses (typically 250-500 mg daily). Reported side effects are rare and mild, including:
Nausea or stomach upset
Headaches
Fatigue (in some cases)
However, because human trials are limited, long-term safety remains under investigation. Pregnant or breastfeeding individuals, as well as those with chronic conditions, should avoid NMN until more data is available. Always start with a low dose to assess tolerance.
Potential Benefits of NMN
While research is ongoing, NMN’s potential benefits make it a compelling option for many. Beyond boosting NAD+ levels, it may:
Enhance physical endurance and recovery
Support cardiovascular health
Improve cognitive function
Aid in weight management by optimizing metabolism
These effects are based on preliminary studies, primarily in animals, so results in humans may vary. Still, the promise of these benefits drives demand for NMN supplements in the USA.
Alternatives to NMN
If you’re unsure about NMN’s legal gray area, there are other NAD+ boosters worth considering.
One of the most popular is Nicotinamide Riboside (NR). It’s legally sold as a dietary supplement in the U.S. and has been shown in human studies to effectively raise NAD+ levels. Brands like Tru Niagen use this form.
Other NAD+ support options include:
Niacin (Vitamin B3): An older and more affordable way to support NAD+, though higher doses can cause flushing.
Fasting and calorie restriction: Shown to naturally stimulate NAD+ production in cells.
Regular exercise: A proven way to promote healthy mitochondrial function and NAD+ activity.
While NMN may offer a more direct path to NAD+, these options can still support energy, metabolism, and healthy aging, especially if you're looking for clarity and legal peace of mind
The Future of NMN in the USA
The legal status of NMN in the U.S. is still in flux. Several health and supplement groups are pushing back against the FDA’s 2022 decision, arguing that NMN occurs naturally in food and has a history of safe use before drug trials began. If these efforts succeed, NMN could regain recognition as a legal dietary supplement.
For now, NMN remains available but under watch. The FDA has paused enforcement while it reviews petitions and legal challenges, giving brands and consumers more time to access the product. That said, this pause is temporary. Future rulings could change the game again.
Keeping an eye on FDA updates and industry news can help you stay ahead if the situation shifts. For now, buying from reputable sources and staying informed is the best approach.
