Every cell uses NAD+ to turn food into energy and to repair its DNA, and NAD+ levels fall as we age. NMN is the direct building block your body turns into NAD+. A daily capsule tops it back up.
Top up NAD+. Power every cell.
Human trial · 60 daysBlood NAD up 5.7×
Not just theory. In the human trials below, NMN raised blood NAD+, the molecule every cell runs on. It fuels your mitochondria, activates sirtuins and powers cellular repair.
Adults taking 600mg a day for 60 days walked 145m further in six minutes, against 5m on placebo.
Multicentre trial of 80 adults, 2023In older men, 12 weeks of NMN raised blood NAD+ and was well tolerated, with signs of better gait speed and grip strength.
Randomised controlled trial, 2022Muscle insulin sensitivity was 25% higher after 10 weeks of NMN, in a double-blind, placebo-controlled trial.
Published in Science, 2021NMN works at the cellular level, so the benefits build the longer you take it.
Many people feel more even energy through the day, with fewer afternoon slumps.
Clearer thinking and quicker recovery are common reports as the cellular benefits become more noticeable.
In the 2023 trial, average blood NAD was higher at day 60 than at day 30 in every NMN group.
One bottle lasts 90 days. Cellular benefits build with consistent, long-term use.
Typical experience based on customer feedback. Individual results vary.
NMN (nicotinamide mononucleotide) is the direct building block of NAD+. Each capsule holds 500mg of β-NMN, the form named on the label, so every capsule delivers the same dose.

NMN has been tested in four randomised, placebo-controlled trials in people, with 255 participants between them. Here is one clear result, then three more.
Adults took a placebo or 300mg, 600mg or 900mg of NMN a day. Blood NAD rose at every dose, and six-minute walking distance rose by 145m on 600mg, against 5m on placebo. One Eternal Elixir capsule is 500mg, which is not a dose this trial tested.

“Consistent product. No stomach upset, which is what put me off NMN before.”

Most NMN sold in Australia comes in 125mg or 250mg capsules, so a full 500mg serve takes two to four capsules. We priced every option by the 500mg serve, label by label.

NMN refills your NAD+. TMG covers what that refill uses up. Together they make a complete daily routine, not half of one.
One capsule gives your body 500mg of NMN, the direct building block for NAD+, the molecule every cell uses for energy and repair.
Each time NAD+ is used, your body clears the leftover nicotinamide through methylation, drawing on its supply of methyl groups.
TMG (trimethylglycine) is a methyl donor. 2,000mg a day restocks those methyl groups and supports healthy homocysteine levels.


Want resveratrol too? The NAD+ & Methylation Stack bundles all three and saves $24.98.
Refuel. Rebalance. Protect.






Take your NAD+ routine all the way. NMN builds your NAD+, TMG restocks the methyl groups your body spends using it, and trans-resveratrol brings antioxidant support. Three full-size bottles at stack pricing.
Want all three to run out together? The 90-day supply (1 NMN, 2 Trans-Resveratrol, 3 TMG) is $251.99, saving $62.95. That's a 3-month supply of all three for $2.80 a day.

NMN boosts NAD+ levels in your cells, which naturally decline with age. NAD+ is essential for cellular energy production, DNA repair, and activating sirtuins (longevity genes). Each capsule provides 500mg of pure NMN to restore NAD+ and support healthy aging at the cellular level.
Many users report increased energy within 1–2 weeks. Cellular-level benefits typically become more noticeable after 4–8 weeks of consistent daily use. For optimal longevity support, we recommend sustained daily use.
The label says to take 1 capsule a day on an empty stomach, or as directed by your physician. We suggest the morning, and many users report better daytime energy when they take it early.
Yes. NMN pairs well with other longevity supplements like resveratrol, which also activates sirtuins. Many people stack NMN with TMG (trimethylglycine) to support methylation. Always consult your healthcare provider about your specific supplement regimen.
In the 2023 trial above, daily NMN of up to 900mg for 60 days was well tolerated and no safety issues were found. The 2022 trial in older men also found it well tolerated. Follow the label. It is for adults only and not for use if you are pregnant or lactating. If you have a medical condition or take prescription medication, check with your doctor first.
At 1 capsule a day, as the label directs, a bottle lasts 90 days. Two bottles last six months, three last nine and five last fifteen. Take more than one a day and it runs out sooner.
We dispatch fast from within Australia, to every state and territory. Metro delivery usually takes 3 to 5 business days and regional delivery 5 to 7. Shipping is free over $100. Below that, standard shipping is $10, and express is $13 at checkout.

Sceptical for the first two weeks then it quietly clicked. Steadier energy, no jitters like coffee gives me.
Started half dose as I'm sensitive to most things. Built up fine, no flushing or palpitations.

Works well.
Good product.
Does what it says.
Decent, but I've had comparable for less.

Consistent product. No stomach upset, which is what put me off NMN before.
On the NMN capsules for about a month now. Steadier energy through the afternoon is what I notice most.
Great quality.
Happy overall. Courier left it at the door without a note once.

Bought the capsules on the back of some YouTube research. Hard to measure but I like how I've been feeling.
Easy to take.
Really happy with the Eternal Elixir products. Fast shipping and great quality. Would buy again!
Very prompt in delivery. Not seeing any results yet, but there's 3 months worth of tablets in this bottle so I'll check again once it's finished.
real deal nmn. i use it to help my energy levels
Great value NMN. I stack this with Eternal Elixir’s NR and also TMG as part of Dr Sinclair’s recommendations
I'm 52 and feel like I'm 40 again. The mental clarity and sustained energy throughout the day is incredible. Best anti-aging supplement I've tried.
After researching NMN extensively, I chose this brand for the quality and dosage. Two months in and I sleep better, recover faster from workouts, and have more mental energy. Highly recommend!
Started taking this based on longevity research. After 6 weeks, I notice better endurance during cardio and clearer thinking. Will continue using.
Tried several brands and this one gives the most consistent energy. No afternoon crashes anymore.
I'm a marathon runner and my recovery time has improved dramatically. Less muscle soreness and better endurance.
Pure NMN, good dosage. Effects were noticeable after about 2 weeks. Mental fog lifted and energy improved.
Unexpected benefit - my skin tone is more even and I have fewer fine lines. The anti-aging effects are real!
Consistent results month after month. Energy, mental clarity, and overall vitality are all improved. Worth the investment.
At 58, I feel better than I did at 48. This supplement is backed by science and it shows in the results.
Taking this as part of my healthy aging protocol. Noticed better energy and mental sharpness after a few weeks.
My NAD+ levels tested higher after 2 months. Energy is up, sleep is better, and I'm recovering faster from workouts.
High purity, proper dosage, and it works. I've tried other brands but keep coming back to this one.
Energy levels have definitely improved. Takes a few weeks to feel the full effects but worth the wait.
Clean product, effective dosage. My biohacker friends all use this brand. Noticeable improvements in vitality.
