NMN in Germany and the EU

Nicotinamide mononucleotide (NMN) is a small molecule your body uses to make NAD+ (nicotinamide adenine dinucleotide). NAD+ in turn helps every cell carry out the chemical reactions it needs to function. Its level is thought to fall with age. That idea grew into a whole supplement trend: top up NAD+ from the outside and you might slow some parts of ageing. Harvard's David Sinclair is its best-known advocate, and the human research is young: early trials show real signals, while the big questions are still open.

Those early signals come from small trials, each with a modest but real finding. In one, postmenopausal women with prediabetes and overweight or obesity took 250 mg of NMN a day for 10 weeks.^[5] Their muscles became more sensitive to insulin, the hormone that clears sugar from the blood.^[5] In older men the same daily dose raised blood NAD+.^[6] Walking speed and grip improved only slightly, a result the authors say larger studies need to confirm.^[6] Pooled together, they have not yet added up to a clear metabolic benefit in a review of 15 small trials.^[17] On the plus side, that review found no extra side effects over periods of up to 24 weeks.^[17] So NMN reliably raises a blood marker, NAD+, and was well tolerated in these short trials; whether that adds healthy years is the open question no trial has answered so far.

Because the science is still young, this guide sticks to the legal picture in Germany and the EU. It covers whether NMN may be sold, what the coming authorisation changes and what you can take legally in the meantime. The biology and the trial doses are in the NAD+ boosters section of our supplements guide, though those doses come from US and Asian trials, not from EU-authorised products. The only dose named here is the 300 mg a day that EFSA assessed and the draft authorisation sets as the maximum.^{[7, 13]} That figure is a legal ceiling, not dosing advice. Before any ceiling matters, though, the law has to allow the capsules in your online basket to be sold to you at all.

As of October 2026, NMN may not be sold as food or as a food supplement anywhere in the EU.^[1] That holds even though all 27 Member States approved an authorisation on 25 September 2026.^[14] The rule behind the ban is the EU Novel Food Regulation (Regulation (EU) 2015/2283). It treats as novel any ingredient that people in the EU did not eat in significant amounts before 15 May 1997.^[1] Such a food needs an authorisation before anyone may sell it.^[1] NMN falls under that rule, since EFSA assessed it under the regulation and the Commission is authorising it as a novel food.^{[7, 13]}

How far the authorisation has got

The first NMN to go through that process belongs to EffePharm, a company based in Shanghai that markets its NMN as Uthever®.^{[7, 13]} Its path through the EU system so far:

1. 2 August 2023: EffePharm applies for authorisation.^[13]
2. 11 May 2026: EFSA publishes its opinion that up to 300 mg a day is safe for adults, excluding pregnant and breastfeeding women.^[7]
3. 25 September 2026: the Member States' Standing Committee backs the Commission's draft authorisation, with all 27 countries in favour.^[14]
4. Still open (as of 21 October 2026): the Commission formally adopts the regulation and publishes it in the Official Journal; it enters into force 20 days after publication.^[13]
5. Then: for five years only EffePharm's NMN may be sold, and after that any NMN that meets the listed specification.^[13]

The science and the vote are done, but as of 21 October 2026 the regulation had not been published.^{[13, 14]} Until it is, NMN still may not be sold as a food supplement.

What the authorisation will allow

Once in force, the authorisation covers NMN in food supplements for adults at up to 300 mg a day, excluding pregnant and breastfeeding women. The label must call it "beta-nicotinamide mononucleotide" and say the supplement is for adults only, not for pregnant or breastfeeding women.^[13] Those 300 mg are also where EFSA's safety verdict stops. EFSA reviewed human studies that used up to 900 mg a day for 60 days or up to 250 mg a day for 24 weeks.^[7] Those studies reported no adverse effects, but that does not make higher routine intakes safe.^[7] None of the human safety data run longer than 24 weeks.^[7]

The animal data set the same boundary from the other side. In a 90-day rat study the highest dose changed the reproductive organs, while 400 mg per kg of body weight a day caused no harm.^[7] EFSA judged the gap between that harmless dose in rats and 300 mg a day in adults to be a sufficient safety margin.^[7]

The authorisation is also not open to every maker at first. For five years after the regulation enters into force, only EffePharm may place this NMN on the EU market.^[13] Any other company needs its own authorisation in that period, based either on its own data or on EffePharm's agreement to use the protected data.^[13] After that, any supplier may use the Union-list entry (the EU's list of authorised novel foods) if its NMN meets the listed specification.^[13] That means synthetic β-NMN, at least 99% pure, used under the same conditions.^{[1, 13]} NR, the NAD+ precursor that is already authorised, went the same way, and ChromaDex's exclusivity for it ended on 20 February 2025.^[2]

Outside the EU

Other countries treat NMN differently, but a product sold to someone in Germany has to meet EU food law wherever it comes from.^[1] The table shows the status in the neighbouring and supplier countries German buyers ask about (as of October 2026).

Sources: EU regulation, draft act and vote^{[1, 13, 14]} FDA letter,^[4] EFSA opinion,^[7] EU food fraud report.^[19]

The US row has the most history behind it. The FDA moved NMN out of the dietary supplement category in late 2022 because of a parallel drug filing for the same molecule.^[4] After the Natural Products Association and the Alliance for Natural Health petitioned, the agency reversed that decision itself, without a court ruling, in a response letter of 29 September 2025.^[4] NMN now counts as a US dietary supplement again, but EU food law still decides what may be sold to a buyer in Germany.^{[1, 4]}

You can still find NMN in German online shops in October 2026, but no shop may sell it for people to take. The risk that comes with an unchecked product is yours, so four things are worth knowing before you order.

1. It is sold anyway, and authorities act on it. NMN turns up in shops in Germany, Austria and Switzerland as well as elsewhere in the EU, usually labelled "laboratory chemical" or "research use only". That label does not make NMN a legal food or take the seller outside food law, and all it really tells you is that nobody has assessed the product for human use. In 2021 a Bavarian court upheld a ban on all NMN products of a German online shop, finding that calling a product a chemical is not enough when it is obviously sold for people to take.^[18]

Shipping from another EU country does not make the sale legal either. Parcels within the EU pass no customs check, so nobody stops them at a border. The rules still apply, though, and authorities act on them: in January 2025 Germany reported an NMN supplement from Czechia to the EU's food fraud network.^[19]

2. There is no normal prescription. There is no approved NMN medicine in Germany, so there is no normal prescription for it, including the pink Kassenrezept used for public health insurance. Some private longevity clinics offer NAD+ infusions instead, which are a different substance under different rules and are covered with the legal alternatives.

3. Nobody vouches for what is inside. Without an authorisation there is no legally fixed specification these capsules have to meet. Food inspectors can take samples, as the Bavarian food safety authority did in the case behind the 2021 ruling.^[18] A spot check like that still does not tell you what is in the batch you buy, so purity, the real NMN content and the label are only as good as the seller makes them. That is why an independent lab certificate matters if you decide to buy before the authorisation.

4. Health claims are banned. For a food supplement, slogans like "NMN rejuvenates cells" or "NMN extends life" are banned by the EU Health Claims Regulation (Regulation (EC) No 1924/2006, called HCVO in Germany).^[12] It only allows claims that are scientifically proven and on the EU's authorised list.^[12] Once a claim turns medical, for example "NMN prevents Alzheimer's", Germany's Heilmittelwerbegesetz (HWG), the law on advertising medicines and treatments, adds its own rules.^[3]

Once the authorisation is in force, a legal NMN supplement will be easy to recognise. Its label will name "beta-nicotinamide mononucleotide", keep to at most 300 mg a day and say it is for adults only, not for pregnant or breastfeeding women.^[13] For the first five years, NMN from other makers stays unauthorised unless it gets its own authorisation.^[13] A product without those marks is therefore still a grey-market buy.

The legal alternative in Germany is nicotinamide riboside chloride (NR), another molecule the body turns into NAD+. The EU authorised it as a novel food in 2020, so it may be sold here as a food supplement.^[2] Vitamin B3 in its forms niacin and nicotinamide (also sold as niacinamide) has been allowed for much longer and is cheap. NAD+ drips, by contrast, are a medical procedure rather than a supplement. The table compares the four on legal status, the maximum amount and whether they raise NAD+ in human blood (as of October 2026).

Nicotinamide riboside (NR). NR has the broader human trial record of the two precursors: it reliably raises NAD+, and turning that into measurable health gains is the step the trials are still working on. On the first point the trials agree. Single doses of 100 to 1,000 mg raised NAD+ markers in the blood, and the higher the dose, the bigger the rise.^[8] In healthy middle-aged and older adults, 500 mg twice a day for six weeks also raised NAD+ and was well tolerated.^[9] Health outcomes are where the research still has work to do. In a 12-week trial in obese, insulin-resistant men, 1,000 mg twice a day did not improve insulin sensitivity, meaning how well the body responds to insulin.^[10] Daily totals of 1,000 and 2,000 mg in the two longer trials are three to seven times the EU maximum of 300 mg a day for NR.^{[2, 9, 10]} That makes them no guide to dosing.

Where NMN and NR both stand. Both raise NAD+ in blood, to a similar degree in a head-to-head trial.^[16] Neither, however, has a trial in people showing a longer life or fewer diseases of ageing. The largest NR outcome trial so far gave 410 people with early Parkinson disease 1,000 mg a day for a year.^[21] Their symptoms did not improve, and their scores came out slightly worse than on placebo.^[21] That dose is more than three times the EU maximum, and the trial says nothing about healthy people taking permitted doses. The rejuvenation effects that made the field famous come mostly from rodents and cell lines, promising groundwork that human trials still need to confirm.

Long-term high doses carry one more caveat. When the body breaks down excess vitamin B3, it makes two end products called 2PY and 4PY. In an analysis of heart patients, higher blood levels of both were linked to more heart attacks and strokes over three years.^[11] NMN raises both, and in an early human study they rose with the NMN dose.^[15] Since the heart study did not test NMN or NR, this is a link rather than proof of harm. Still, it is a reason not to take high doses for years.

Niacin and nicotinamide (vitamin B3). Vitamin B3 is the old and cheap route to NAD+, though not a sure one. Niacin (nicotinic acid) causes the classic warm facial flush, and nicotinamide does not. In a 14-day randomised trial, 500 mg of nicotinamide a day raised blood NAD+ only briefly after each dose, while NR and NMN raised it lastingly.^[16] Higher doses have limits of their own. For adults, the EU tolerable upper intake levels are 900 mg a day for nicotinamide and 10 mg a day for nicotinic acid.^[20] They mark the most a day not expected to cause harm, and none were set for pregnancy and breastfeeding because the data are inadequate.^[20] The missing EU-wide maximum for supplements does not mean any dose is safe, so talk to your doctor before taking more.

NAD+ IV drips. NAD+ drips are offered by some private practices and by Heilpraktiker offering longevity services, Germany's licensed non-medical practitioners. They are a medical procedure, not a supplement, so ask who makes the infusion product and who is responsible if something goes wrong. Evidence for lasting effects is thin, the sessions are expensive, and you pay for them yourself.

Lifestyle. Exercise, enough sleep and not overeating need no authorisation, stay the foundation and are worth doing for their own sake. How much they change NAD+ in people is not well established, though. Among the supplements, NR is the authorised NAD+ precursor you can try today, within its limits.^[2] It raises blood NAD+ dependably, which makes it a sensible experiment for the curious, and whether that higher level adds healthy years is the open question it shares with NMN.

If you buy NMN before the authorisation is in force, you are buying an unauthorised product. Six checks decide how much risk you take on with it. Overblown longevity or disease claims are the quickest warning sign, because they point to a careless seller and are likely illegal under EU rules as well.^[12]

1. Where is the seller based? Every product sold to people in the EU has to meet EU food law, wherever it was made.^[1] What differs is enforcement: a recall, a complaint or a liability claim is much harder to pursue against a seller outside the EU.

2. Is there an independent certificate of analysis (COA)? A serious maker hands over a COA, a test report on your batch from an independent lab. It should confirm that the powder really is NMN and state both its purity and how much NMN it contains, and the list below shows the details worth checking.

What an NMN certificate of analysis should show:

• Batch or lot number that matches the bottle you received
• Assay method: how the lab measured the content, ideally HPLC, which separates the compounds in a sample and measures each one, or qNMR, a magnetic-resonance method that measures how much of a substance is present
• Purity: at least 99%, the specification EFSA assessed and the draft authorisation lists.^{[7, 13]}
• Heavy metals: lead, cadmium and mercury within the EU limits for food supplements (3, 1 and 0.1 mg/kg); the draft specification also caps arsenic at 0.05 mg/kg^{[7, 13]}
• Microbiology: within the limits in the specification, for example no Salmonella in 25 g^[13]
• Testing lab: an independent third-party lab, not the maker's in-house lab

Even a clean certificate has a limit. Never inject or infuse NMN or NAD+ powder bought online, because a lab certificate does not make a powder sterile or fit for injection.

3. How is the product labelled? "Dietary supplement" means the seller is using the regulated food channel, which is not allowed for NMN without novel food authorisation^[1] "Research use only" or "not for human consumption" does not make the sale legal either.^[18]

4. What does your doctor say? A doctor who knows the NAD+ research is a good sounding board, and in Germany that conversation often happens in a self-pay longevity appointment.

5. Are the promised effects realistic? Serious sources talk about NAD+ levels and mechanisms. A product or seller that promises longer life, rejuvenation or disease prevention likely breaches the EU Health Claims Regulation,^[12] and the HWG as well if it is framed as medical treatment.^[3]

6. Do you have a cancer history? If you have an active or recently treated cancer, be careful here. Lab and mouse studies suggest that NAD+ metabolism can feed tumour growth and inflammation. That is not proof of harm in humans, but it is reason enough to use NMN or NR only together with your oncology team.

In our reading, an NAD+ precursor is a reasonable experiment for a curious adult, and the lower-risk ways to run it are to wait for the labelled, authorised NMN or to take authorised NR in the meantime.^{[2, 13]} Set a fixed trial period and note how you feel and perform before and after, so you can judge it on your own results. If you take NR, stay within its limits: 300 mg a day for adults and 230 mg in pregnancy and breastfeeding.^[2]
