DoNotAge Review Australia 2026: Is It Worth It?

Last updated: September 25, 2026 · Originally published: August 15, 2026 · By Eternal Elixir Editorial

Quick answer: DoNotAge.org is a UK-based longevity brand that sells single-ingredient supplements and runs an Australian store priced in AUD. Its Pure NMN costs A$129 for 60 capsules of 500mg, and the page recommends 1,000mg a day, so a bottle lasts 30 days and costs $4.30 a day at that serving. Its bulk NMN powder is far cheaper per gram, down to $0.56 per 500mg in a 1 kg bag that costs A$1,124. Orders to Australia take 3 to 7 working days to arrive. For most Australian buyers, our pick is Eternal Elixir NMN 500mg: 90 capsules of 500mg for $59.99, one capsule a day at $0.67, sent from Sydney within 24 hours.

Eternal Elixir sells competing longevity supplements, so read this as a competitor’s review. NMN 500mg is our product and our pick. Every DoNotAge figure below comes from DoNotAge.org’s own Australian store pages, read in September 2026, and every study is described with who took part, how many people, the dose and what changed. We have not lab-tested DoNotAge’s products or our own for this review. If you are comparing several brands rather than just this one, our DoNotAge alternatives comparison covers eight options, and our longevity supplements comparison by daily cost ranks the wider Australian market.

DoNotAge Review Australia: The Short Verdict

DoNotAge (people also search for it as “Do Not Age”) sells NAD+ precursors, polyamines, resveratrol, TMG and a few formulas under its own name. Its Trustpilot profile lists the company in the United Kingdom.

Three things work in its favour. It sells single ingredients, so you can see exactly what you are taking. It states the amount per capsule or scoop on each page. And it says every batch of Pure NMN is third-party lab tested to a 99.8% purity standard, with certificates available on request.

For Australians, the catch is cost and distance. DoNotAge’s recommended NMN serving is two capsules, which doubles the daily cost of its capsules. Its cheapest per-gram prices need a large upfront order. And parcels come from overseas, with a stated 3 to 7 working days for rest-of-world delivery.

If you buy a year’s supply of powder at once, DoNotAge can be good value. If you want to try one bottle of capsules, a local brand costs less per day and arrives sooner. That is the whole decision, and it is similar to the trade-off in our guide to AgeMate alternatives for Australian buyers. Our Tru Niagen review for Australia covers a brand that takes a different route to NAD+, through NR.

What DoNotAge Actually Sells, and What It Costs in AUD

DoNotAge’s Australian store shows prices in AUD. The table puts its four core products next to our equivalents, with the cost of each label serving worked out from the stated amount per capsule and the serving each page recommends. Prices are as of Sep 2026.

Our prices come from our live product pages. DoNotAge prices were read from its Australian store in September 2026 and exclude subscriptions and multi-buy discounts. Check both before you buy.

Add NMN 500mg to cart · $59.99

The table cuts both ways, and it is fair to say so. DoNotAge’s 1 kg NMN powder works out at $0.56 per 500mg, cheaper than our capsules, and its 183 g bag at $0.66 is about level with them. Its TMG costs less per day than ours at each label’s serving, though our serving is twice the amount, so ours is cheaper per gram ($0.75 per 1,000mg against $1.07). Where local capsules win clearly is NMN in capsule form, resveratrol and spermidine, and on delivery time.

DoNotAge also sells larger 366-capsule containers (Pure NMN A$708, which is $1.93 per 500mg) and a Subscribe & Save option advertised at up to 43% off. Its subscriptions are sent as a single annual shipment, so they suit people committing to a year of one compound. Multi-buy prices on the 60-capsule NMN drop to A$116.10 each for three and A$103.20 each for six.

DoNotAge NMN: The 1,000mg Serving and What It Does to Cost

Each DoNotAge Pure NMN capsule holds 500mg, the same as ours. The difference is the recommended serving. DoNotAge’s page gives “Recommended daily serving: 1000mg NMN”, and its FAQ gives a range of 500mg to 1,000mg taken as one to two capsules. Our label directs one 500mg capsule a day.

At two capsules a day, a 60-capsule DoNotAge bottle lasts 30 days, and a 90-capsule bottle of ours lasts 90 days at one capsule a day. Compare the cost of the amount you actually plan to take, not the bottle price. Our NMN dosage guide for Australia walks through the doses used in trials, and the next section summarises them.

Whether 1,000mg does more than 500mg is not settled. In the largest dose-comparison trial so far, blood NAD+ was highest at 600mg and 900mg a day, and nobody has tested whether higher doses change anything people can feel over years.

The Science Behind DoNotAge’s Headline Ingredients

DoNotAge leans on published research more than most brands, so it is fair to judge the evidence on its own terms and to be precise about what kind of evidence it is.

NMN. The human trials are small, placebo-controlled and short:

• 80 healthy middle-aged adults took placebo or 300mg, 600mg or 900mg of NMN a day for 60 days. Blood NAD+ rose in every NMN group, highest at 600mg and 900mg, and six-minute walking distance improved more than with placebo (Yi et al., GeroScience, 2023).
• 108 older Japanese adults took 250mg of NMN or placebo once a day for 12 weeks. The group taking it in the afternoon showed the largest gains in a sit-to-stand test and the largest drop in drowsiness (Kim et al., Nutrients, 2022).
• A July 2026 pooled analysis of 15 randomised trials, at doses from 250mg to 2,000mg a day for up to 24 weeks, found no rise in adverse events or liver enzymes, and no clear effect on body weight, fasting glucose or blood fats (Yang et al., Nutrients, 2026).

Spermidine. The strongest results are in animals. Oral spermidine extended lifespan in mice and kept older mouse hearts working better (Eisenberg et al., Nature Medicine, 2016). In 829 adults aged 45 to 84 followed for about 20 years, higher spermidine intake from food was linked to lower death rates, which is an observational finding and cannot show cause (Kiechl et al., American Journal of Clinical Nutrition, 2018). In the one year-long capsule trial, 100 adults aged 60 to 90 took 0.9mg of spermidine a day or placebo for 12 months, and memory scores did not differ (Schwarz et al., JAMA Network Open, 2022).

Resveratrol. Results pull both ways. 46 healthy, overweight older adults who took 200mg a day for 26 weeks remembered more words than the placebo group (Witte et al., Journal of Neuroscience, 2014). But in 27 inactive men aged about 65 doing eight weeks of high-intensity training, 250mg a day of trans-resveratrol blunted the fitness and blood pressure gains seen with placebo (Gliemann et al., Journal of Physiology, 2013).

TMG. DoNotAge sells TMG to pair with NMN, and many people take the two together. We found no human trial showing that adding TMG changes what NMN does, so treat the pairing as a popular practice rather than a tested one.

Where any honest review should slow down is the jump from these findings to promises about human lifespan. The mouse data are strong. The human data are small, short or observational. Any brand, DoNotAge or ourselves included, that presents this as proof of longer human life is overselling it. We cover the polyamine evidence in more depth in our spermidine supplement comparison, and how the two compounds differ in our spermidine vs NMN breakdown.

Buying DoNotAge from Australia: Delivery, Currency and Reviews

DoNotAge’s Australian store shows prices in AUD, so you no longer need to convert from US dollars to compare. Delivery is the part that has not changed. The site lists delivery within 2 working days for the UK, 2 to 3 for the USA, 3 to 4 for the EU and 3 to 7 for the rest of the world, which includes Australia. Free shipping applies on worldwide orders over $300, compared with $50 or £50 in the USA and UK.

The one Australian retailer we found with a DoNotAge brand page, Fairfield Nutrition, listed only DoNotAge collagen (out of stock) and blue-light glasses when we checked, not NMN or spermidine.

On Trustpilot’s Australian site, DoNotAge.org had a TrustScore of 3.9 out of 5 from 564 reviews when we checked. 81% of those reviews were five stars and 11% were one star, so experiences are mostly good but not uniform. Read the recent one-star reviews for the issues that matter to you, such as delivery times, before a large order.

Who DoNotAge Suits, and Who It Doesn’t

DoNotAge suits you if you want single-ingredient products, you are happy to buy NMN as powder in bulk, and you plan to take one compound for a year. Its 183 g and 1 kg powders are competitive on price per gram, and its annual subscriptions cut the cost further.

DoNotAge is a poor fit if you want capsules, you want to trial one bottle before committing, or you want your order this week rather than after an international delivery window. At two capsules a day, its 60-capsule NMN costs $4.30 a day, several times the cost of a one-capsule local 500mg product. Australian buyers in that group are usually better served by a local brand.

You may see scepticism about DoNotAge’s marketing in forums. Marketing style is not evidence about what is in a capsule either way. The useful check is the batch certificate, which DoNotAge says it provides on request.

The Australian Alternative: Eternal Elixir NMN 500mg

Eternal Elixir NMN 500mg holds 500mg of NMN in each capsule, and the label directs one a day, preferably in the morning. A bottle holds 90 capsules and lasts three months, and at $59.99 each serve costs $0.67.

• Lower daily cost in capsule form: $0.67 a day against $4.30 for DoNotAge’s capsules at its recommended serving, or $2.15 per 500mg.
• Local dispatch: orders ship from Sydney within 24 hours, and orders over $100 ship free.
• Batch testing on request: our product page says every Eternal Elixir batch is third-party lab tested for purity and potency, and that you can ask for the current batch certificate of analysis.
• Savings on more bottles: two bottles save 10%, three save 15% and five save 20%. A 30-day money-back guarantee applies, and Afterpay is available.

Who it suits: Australians who want plain 500mg NMN in one capsule a day, at a low daily cost, delivered locally. Who it doesn’t suit: anyone who wants NMN as a powder, or who wants to take 1,000mg a day from a single product without doubling up. It is not for use in pregnancy or breastfeeding, or by anyone under 18, and if you take prescription medicines, talk to your doctor first.

If you want to rebuild a DoNotAge-style routine locally, our range covers the same compounds: NMN, Spermidine 10mg, Trans-Resveratrol and TMG. Our Cellular Longevity Stack ($139.99) combines NMN, spermidine and trans-pterostilbene in one order. Our NMN and TMG stack comparison and longevity stack comparison explain how people combine them, and our NMN vs NR comparison helps if you are still choosing a precursor.

Does NMN really work?

In placebo-controlled trials, NMN raised blood NAD+ levels and was linked to small improvements in walking distance and sit-to-stand tests in middle-aged and older adults. The trials were small and lasted weeks, not years, and pooled data show no clear effect on weight, glucose or blood fats. No NMN trial has shown longer life in people.

Which DoNotAge products compare with Eternal Elixir’s?

Four overlap directly: NMN, resveratrol, spermidine and TMG. Ours cost less per label serve for NMN capsules, resveratrol and spermidine. DoNotAge’s TMG costs less per day at its smaller serving, and its bulk NMN powder costs less per 500mg if you buy 183 g or more.

The Verdict

DoNotAge is a credible single-ingredient brand with open testing practices and an Australian store in AUD. For Australians, its best value is bulk NMN powder bought a year at a time. For capsules, and for anyone who wants a supplement in hand within days, a local brand costs less per day.

Our pick for Australian buyers: Eternal Elixir NMN 500mg, at $0.67 a day for one 500mg capsule, in a 90-capsule bottle sent from Sydney within 24 hours.

If you want bulk NMN powder and can wait: DoNotAge’s 183 g or 1 kg bags, at $0.66 and $0.56 per 500mg.

Whichever you choose, settle on the daily dose you intend to take before you compare prices. A bottle is only cheap if it lasts as long as you think it will.
