If you have searched for NMN at Boots, you are asking a sensible question: NMN (nicotinamide mononucleotide) is one of the most talked-about longevity supplements in the UK, and Boots is the country's most trusted high-street pharmacy. So does Boots actually sell it — and if so, is buying your NMN there the best choice? The short answer is yes, but the range is narrow and availability is patchy. If you want a wider, third-party-tested choice, you can buy NMN supplements in the UK from a specialist instead, with the Welzo Ultra Purity NMN Pro 1000 as our 99% β-NMN pick at a full 1,000 mg daily dose. For the background, our pillar guide to longevity supplements shows where NMN sits among the alternatives, our NMN benefits, side effects and dosage guide covers the evidence in full, and you can browse the wider anti-ageing and longevity range. This guide covers exactly what Boots stocks, how much it costs, what the science says, and how the options compare with buying NMN from a specialist.
Quick answer: Boots sells NMN online through the third-party brand NMN Bio, offering NMN capsules (250 mg and 500 mg), plus TMG, a NAD+ brain formula and magnesium. Stock is often limited to home delivery and can show as "temporarily unavailable". Boots does not currently stock its own-brand NMN.

Yes. Boots sells NMN through its online marketplace, supplied by the UK longevity brand NMN Bio, which describes itself as the first NMN supplement to be listed at Boots UK. The products are sold as food supplements — meaning no prescription is needed — and you can collect Advantage Card points when you buy them.
There are a few things to know before you rely on Boots as your NMN source:
Boots' longevity offering centres on the NMN Bio range, with a handful of NAD+-adjacent products from other brands. Here is what has been listed:
The core products are NMN Bio NMN 250 mg (30 capsules) and NMN 500 mg (30 capsules). Both contain nicotinamide mononucleotide with a simple vegetable-cellulose capsule shell and no unnecessary fillers. Boots' own guidance for the 500 mg product suggests one capsule daily, preferably on an empty stomach about an hour before breakfast — advice that lines up with the wider evidence on when to take NMN. If you are unsure which strength suits you, our guide to NMN dosage by age is a useful starting point.
Boots also lists NMN Bio TMG 500 mg (90 capsules). TMG is a methyl-group donor that is often paired with NMN because NAD+ metabolism can consume methyl groups. Whether you actually need it depends on your diet and other supplements — we cover this in detail in do I need TMG with NMN? and in our guide to buying TMG in the UK.
The NAD+ Brain formula (90 capsules) is a nootropic-style blend combining ingredients such as citicoline, L-theanine, L-tyrosine, apigenin, fisetin, inositol, phosphatidylserine and a modest dose of caffeine, alongside B-vitamins, vitamin C and zinc. It is aimed at focus and cognitive support rather than being a pure NAD+ precursor.
Beyond NMN Bio, Boots has stocked a small number of related products, including a Bettervits NMN Complex with resveratrol and quercetin (60 capsules), a SWIISH NAD+ booster with NRC and resveratrol, high-strength CoQ10, and NMN Bio's Oh!Mg magnesium glycinate. If you are trying to build a routine rather than buy one product, our longevity supplements guide and the popular NMN, TMG and resveratrol stack explainer will help you understand how these fit together.
Looking for a higher-strength option?
Most Boots NMN listings top out at 500 mg per capsule. If you want a 1,000 mg dose in a single capsule, see NMN Pro 1000 or browse the full Welzo NMN supplements collection.
Prices vary by product and change frequently, and some lines move in and out of stock. The table below reflects prices seen at the time of writing; always check the Boots website for the current figure before buying.

A 30-capsule pack at one capsule a day is a one-month supply, so the per-month cost of NMN can add up quickly compared with larger pack sizes sold elsewhere. If value is your priority, compare against our roundups of the cheapest NMN in the UK and where to buy NMN in the UK before committing.
NMN is a direct precursor to NAD+ (nicotinamide adenine dinucleotide), a coenzyme found in every cell that is essential for energy production, DNA repair and the activity of "longevity" enzymes called sirtuins. NAD+ levels are known to fall as we age, and this decline has been linked in the research literature to several aspects of cellular ageing. The theory behind NMN supplementation is straightforward: supply the body with more of the raw material it uses to make NAD+, and you may help support NAD+-dependent processes. Our NAD+ supplement guide unpacks this pathway in plain English.
NMN is genuinely backed by peer-reviewed human trials — a rarity in the supplement world — although the evidence is still early and most studies are small.
Importantly, the evidence base is not uniformly positive: some NAD+ precursor trials have shown no performance benefit, and long-term outcome data in healthy people is limited. NMN should be seen as a supplement with encouraging early human data, not a proven anti-ageing treatment. If you are weighing this up honestly, our companion article is NMN a scam? reviews both sides.
None of these are dealbreakers, but they explain why many regular NMN users buy from a specialist longevity retailer instead. To see how Boots stacks up against the alternatives, our NMN at Holland & Barrett and NMN on Amazon UK comparisons are worth a read.
Because NMN is a premium ingredient, quality varies widely — and this is a purchase where cutting corners rarely pays off. Whether you buy from Boots or anywhere else, use the same checklist.
Look for a clearly stated NMN content per capsule (commonly 250–1,000 mg) and a purity figure, ideally 99% or higher. Be wary of "proprietary blends" that hide how much actual NMN you are getting.
The single most useful quality signal is independent lab verification. Reputable brands publish a batch certificate of analysis (CoA) and use third-party testing to confirm identity, purity and the absence of contaminants. If you can't find this information, that is a reason for caution.
Standard capsules are fine for most people, but some prefer sublingual NMN or liposomal NMN for absorption reasons. The evidence on superiority is mixed, so match the format to your preference and budget.
UK or EU manufacture under GMP conditions, clear labelling and honest marketing (no "reverse ageing" cure claims) are all good signs. If you are just getting started, our guide on how to start longevity supplements walks through building a sensible routine.
Human trials have used doses ranging from 250 mg to around 1,000 mg per day, and NMN Bio's own guidance suggests starting lower and building up. Many people begin at 250–500 mg daily. The right amount depends on your age, goals and budget — see NMN dosage by age for a structured approach.
NMN is commonly taken in the morning, often on an empty stomach, in line with Boots' own dosing note for the 500 mg product. There is ongoing debate about food and timing, which we cover in when to take NMN.
In the human trials to date, NMN has generally been well tolerated at typical doses, with no serious adverse effects reported in short-term studies.4 Mild, occasional digestive upset is the most commonly mentioned complaint anecdotally. As with any supplement, more is not necessarily better; our article on NMN overdose explains sensible upper limits. NMN should not be taken if you are pregnant, breastfeeding or under 18, and Boots' own labelling advises consulting a doctor before use if you have, or suspect you have, a medical condition.
Some users add TMG to replenish methyl groups used during NAD+ metabolism, which is why Boots lists the two together. Whether it is necessary for you is individual — read do I need TMG with NMN? before adding it.
Boots is far from your only option. NMN is legally sold as a food supplement across the UK, so you can also buy it from:

Boots does sell NMN and a small selection of longevity supplements, supplied by NMN Bio. If you value buying from a familiar high-street pharmacy and want to earn Advantage Card points, it is a legitimate, convenient option. The trade-offs are a narrow range, frequent stock gaps, smaller pack sizes, a 500 mg maximum strength and limited shelf-level transparency on testing.
For occasional or first-time buyers, Boots is perfectly reasonable. For anyone building a consistent, cost-effective longevity routine — or who wants higher strengths and published certificates of analysis — a specialist retailer usually offers better value and choice. Either way, focus on purity, third-party testing and a sensible dose, and treat NMN as a supporting act to the fundamentals of sleep, movement and a good diet. To go deeper, start with our pillar guide to NMN benefits, side effects and dosage.
Yes. Boots sells NMN online through the third-party brand NMN Bio, including 250 mg and 500 mg capsules, plus TMG and a NAD+ brain formula. These are food supplements, so no prescription is needed, though stock and delivery can be limited.
NMN Bio products are primarily listed online and dispatched directly from the supplier. Some items offer a "find in store" option, but in-store stock is not guaranteed, so it is best to check availability before travelling.
No. Boots does not manufacture its own NMN. Its NMN offering comes from NMN Bio and a few other third-party brands.
Prices vary and change often. Related NMN Bio products such as TMG have been listed at around £29, and combination formulas around £45. Check Boots directly for the current price of the NMN capsules, as figures are subject to change and offers are common.
NMN Bio is a UK-based, scientist-founded brand that manufactures in the UK, which is reassuring. As with any NMN, look for stated purity and independent lab testing. Our third-party testing guide explains what to check.
NMN is sold in the UK as a food supplement and is available without a prescription both online and on the high street, as its listing at Boots demonstrates. It is not a licensed medicine, so it is not intended to treat or prevent disease.
Human studies have used 250–1,000 mg daily. Many people start at 250–500 mg and adjust. See our NMN dosage by age guide, and always follow the product label.
NMN is usually taken in the morning, often on an empty stomach — this matches Boots' own dosing note for the 500 mg capsule. Read when to take NMN for the nuances.
Not necessarily. TMG replenishes methyl groups that NAD+ metabolism can use, which is why the two are often paired, but whether you need it is individual. Our article do I need TMG with NMN? covers this.
Not usually. Because Boots sells smaller 30-capsule packs at up to 500 mg, the cost per gram can be higher than larger specialist packs. Compare options in our cheapest NMN in the UK roundup and the Welzo NMN collection.
