Pure NMN 500mg Capsules in the UK: Human People, Naturecan, ViVa, Voyager Life and Pure Vitamins Compared

Reviewed and updated: 31 October 2026

Pure NMN, in UK shops, usually means a capsule or powder with NMN as the only active ingredient, and the fairest way to compare them is on NMN per daily serving, price per day and what else is (or is not) in the pack. I have put four popular UK “pure NMN” products side by side with our own NMN formula below, using prices and labels checked on 31 October 2026, so you can choose the one that suits you.

Pure Vitamins UK is an independent British brand. We are not connected to, endorsed by or affiliated with Human People, Naturecan, ViVa NMN, Voyager Life or their owners. These brand names are trademarks of their respective owners and are named here only to identify the products compared.

Pure NMN 500mg capsules: the quick answer

• Most single-ingredient NMN capsules hold 500 mg per capsule and suggest one a day. Human People, Naturecan and ViVa all follow that pattern.
• Powder is the low-cost route per gram. Voyager Life’s 100 g powder worked out at £0.30 per gram of NMN on the day we checked.
• Our NMN Supplement is not a pure NMN product. It gives 500 mg NMN across two capsules, plus TMG, resveratrol, pterostilbene, quercetin, CoQ10 and piperine. It suits people who want those together in one routine.
• One thing to know: NMN is under Novel Food assessment in the UK, and research in people is still early, so think of any product as a considered personal choice rather than a sure thing.

Our pick for this guide

Want NMN and TMG in the same capsules?

500 mg NMN per daily serving of two vegan capsules, alongside 500 mg TMG, 100 mg trans-resveratrol, 50 mg pterostilbene, 125 mg quercetin, 100 mg CoQ10 and 5 mg piperine, every dose listed on the pouch. A food supplement, not a replacement for medical advice.

What shoppers mean by “pure NMN”

When people type “pure NMN” into Google, they are normally asking one of three things. Is NMN the only ingredient? Has the raw material been tested for purity? And are there any fillers? Those are fair questions, and the product pages we checked answer them in slightly different ways.

Human People says there are no fillers or bulking agents and quotes 99.5% purity. Naturecan lists NMN and the capsule shell only, with a stated purity of 99%+. Voyager Life sells NMN powder as the single ingredient and quotes 99.9%. ViVa describes its capsules as “500mg pure NMN per capsule” and says its products are tested by an accredited laboratory, without giving a percentage on the page.

So “pure” here is really a description of the formula. It tells you what is not in the capsule. It does not, on its own, tell you how much NMN you get per day or what that costs, which is where a side-by-side view helps. If you are newer to all this, my guide to choosing an NMN supplement in the UK covers the basics first.

Pure NMN UK products compared side by side

Every figure below was read from each brand’s own product page on 31 October 2026. Where a page did not state something, I have left it out rather than guess. Price per day is simply the pack price divided by the number of daily servings, and cost per gram of NMN is the pack price divided by the total NMN in the pack.

At a glance:

• NMN per day at the suggested serving: 500 mg for Naturecan, ViVa and ours; 500 to 1,000 mg for Human People; 1,000 mg for Voyager Life powder.
• Price per day at the suggested serving: Voyager Life £0.30, Naturecan £0.40, ours £0.83, ViVa £1.00, Human People £1.63 (one capsule).
• Single ingredient or formula: the four competitor products are NMN only; ours is a seven-active formula.

Dose: how much NMN per capsule and per day

This is the first number I would look at. Human People, Naturecan and ViVa put 500 mg of NMN in a single capsule. Human People suggests one or two a day; Naturecan and ViVa suggest one. Voyager Life’s scoop gives 1 g, so a level scoop is double a typical capsule.

Ours splits 500 mg of NMN across two capsules, 250 mg in each. That is not because there is less NMN per day. It is because each serving also carries 880 mg of other ingredients, 1,380 mg in total, which is more than one capsule can hold. If you only want NMN and like the idea of one capsule a day, the single-ingredient capsules are simpler.

On the research side, the human studies so far have used a range of daily amounts. An 80-person, 60-day trial in healthy middle-aged adults tested 300, 600 and 900 mg a day and reported that NMN was well tolerated at all three amounts (Yi et al., 2022). A smaller four-week study gave healthy adults 1,250 mg once a day and reported no changes beyond normal variation in the safety measures it tracked (Fukamizu et al., 2022). Both were short, and both were funded or run by NMN producers, so they are useful on tolerability rather than the final word.

It is also worth knowing that in May 2026 the European Food Safety Authority published a safety opinion on one manufacturer’s NMN, considering 300 mg a day safe for the general adult population, excluding pregnant and breastfeeding women (NutraIngredients report). That is an EU assessment of one supplier’s ingredient, not a UK decision, and every product in this comparison, ours included, suggests more than 300 mg a day. If that matters to you, a lower daily amount is easy to choose with powder or by checking with your GP first.

Price per day and cost per gram

Price is where these products differ most, and the honest picture is that ours is not the lowest cost way to buy NMN on its own.

• Voyager Life powder: £29.95 ÷ 100 days = £0.30 a day at 1 g. If you halve the scoop to 500 mg, that becomes about £0.15 a day.
• Naturecan 120 capsules: £47.79 ÷ 120 = £0.40 a day (£0.43 at the regular £51.99 price).
• Pure Vitamins NMN Supplement: £24.99 ÷ 30 = £0.83 a day for 500 mg NMN plus six other actives.
• ViVa 30 capsules: £29.99 ÷ 30 = £1.00 a day.
• Human People 30 capsules: £49.00 ÷ 30 = £1.63 a day at one capsule, or £1.58 a capsule on its subscribe-and-save price of £44.10 for 28.

Larger packs usually bring the daily cost down, and both Naturecan and ViVa list bigger sizes. Delivery also changes the real cost: ViVa states free UK delivery on all orders, Human People and Voyager Life calculate shipping at checkout, and we offer free UK delivery over £25. Prices move often, so please recheck on the day you buy.

Formula: NMN alone, or NMN with TMG and friends

This is the real fork in the road. A pure NMN product gives you one ingredient and lets you build the rest of your routine yourself. Many people like that control.

Our NMN Supplement takes the opposite approach. Alongside 500 mg NMN, each two-capsule serving contains 500 mg TMG (trimethylglycine, also called betaine), 100 mg trans-resveratrol from Japanese knotweed, 50 mg pterostilbene, 125 mg quercetin, 100 mg CoQ10 and 5 mg piperine from black pepper. Every amount is listed on the pouch, with no proprietary blend. I explain why those ingredients sit together in NMN with TMG and resveratrol, and when to take it.

The practical difference is simple. If you already buy TMG or resveratrol separately, a combined formula can mean one pouch instead of three. If you do not want those extras, or you already take one of them at a different amount, a single-ingredient NMN product avoids doubling up.

Capsules or powder?

Capsules are tidy and consistent. You swallow one or two and you are done, and the amount is fixed. Every capsule product here uses plant-based HPMC shells where the page says so (Human People, Naturecan and ours; ViVa’s page does not say).

Powder costs less per gram and lets you choose your own amount, which is handy if you want to stay lower. The trade-off is measuring it out each day. Voyager Life supplies a 1 g scoop and suggests one level scoop a day.

Testing, sourcing and where each is made

Each brand describes its quality checks in its own words. Naturecan states its purity has been verified by an accredited laboratory and shows a certificate of analysis, and states its capsules are made in Europe. ViVa says its NMN is made in the UK and tested by an accredited laboratory. Human People says its NMN was tested in the UK by an ISO-certified laboratory. Voyager Life says its powder was lab tested in the UK in July 2026.

Ours is formulated in the UK and made in a GMP-certified facility, and every batch is tested for active content, microbes and heavy metals before release. We publish the full Certificate of Analysis for our NMN Supplement, with all seven actives checked against the label, so you can read it before you buy.

Whichever product you consider, my best tip is to open the certificate of analysis and check that the batch, the test method and the NMN amount match what the label says.

Which one suits you

There is no single right answer here, and I would rather you buy the product that fits than the one with our name on it.

• Choose Voyager Life powder if you want NMN on its own at the lowest cost per gram and do not mind measuring a scoop.
• Choose Naturecan’s 120-capsule pack if you want single-ingredient 500 mg capsules and a larger pack that keeps the daily cost down.
• Choose ViVa if you want one 500 mg capsule a day in a smaller pack with free UK delivery on every order.
• Choose Human People if you like its no-fillers approach and the option of one or two capsules a day, or want a regular subscription.
• Choose our NMN Supplement if you want NMN together with TMG, resveratrol, pterostilbene, quercetin and CoQ10 in one daily routine, with every dose declared and a published batch certificate.

If a doctor, pharmacist or practitioner suggested a particular product, please check with them before switching, because they may have chosen it for a reason. And if you are still deciding whether NMN is for you at all, my honest take is in is NMN worth taking?.

NMN, NAD+ and why people look into it

NMN (nicotinamide mononucleotide) is a compound related to vitamin B3 that the body uses on the way to making NAD+, a molecule found in every cell and involved in how cells handle energy. Research has shown that NAD+ levels tend to be lower in older tissue, which is why scientists have been studying precursors like NMN and NR. You can read more in what NAD+ is and why it matters and in NMN vs NR.

The human research is still young: most trials are small, short and in healthy adults. That is the honest backdrop to any NMN purchase, whichever brand you choose.

A few cautions worth knowing

• NMN is under Novel Food assessment in the UK.
• Not for under-18s, or for anyone pregnant or breastfeeding.
• If you take medication or have a medical condition, speak to your GP or pharmacist first. Resveratrol, quercetin and piperine in combined formulas are worth mentioning to them specifically.
• Stick to the suggested amount on whichever product you choose.

Frequently asked questions

Is Pure Vitamins the same company as Human People, Naturecan, ViVa or Voyager Life?

No. Pure Vitamins UK is an independent British brand with no connection to any of those companies. Their names appear here only so you can see which products are being compared.

What does “pure NMN” mean on a label?

Usually that the capsule or powder contains NMN as its only active ingredient, often with a stated purity percentage for the raw material. It is a description of the formula, so check the ingredients panel and the certificate of analysis to see exactly what is inside.

Is the Pure Vitamins NMN Supplement a pure NMN product?

No. Ours is a combined formula: 500 mg NMN per daily serving plus TMG, trans-resveratrol, pterostilbene, quercetin, CoQ10 and piperine, each listed separately. If you want NMN as the only ingredient, one of the single-ingredient products above is the closer fit.

Which of these works out cheapest per gram of NMN?

On the prices checked on 31 October 2026, the Voyager Life powder was £0.30 per gram and the Naturecan 120-capsule pack was £0.80 per gram. Prices change often, so recheck on the day you buy.

Is NMN allowed in the UK?

NMN is under Novel Food assessment in the UK. In the EU, EFSA published a safety opinion in May 2026 on one manufacturer’s NMN, but that is not a UK authorisation. If you have a medical condition, take medication, or are pregnant or breastfeeding, speak to your GP or pharmacist before taking it.
