Last updated: May 6, 2026 · By Eternal Elixir Science Team · 8 products tested

Anti-aging supplements have left the biohacker fringe. They are now mainstream longevity science.. According to PubMed, a 2024 Cell Metabolism review by Guarente, Sinclair and Kroemer ([DOI link](https://doi.org/10.1016/j.cmet.2023.12.007)) catalogued eight categories of compounds now in human anti-aging trials — including NAD+ precursors, spermidine, senolytics and TORC1 inhibitors. The challenge for Australians is that most “best of” guides on Google list overseas-only brands, ignore AUD pricing, and bury the per-dose cost behind huge bottle counts. We fixed that.

This guide tests eight anti-aging supplements you can actually buy in Australia today, ranks them by clinical evidence, dose, purity, AUD price-per-dose, and shipping speed. It tells you exactly which compound to start with based on your goal. Four of the eight come from Australian brands, three are pharmacy-available, and one is a premium iHerb import. We disclose where Eternal Elixir wins and where it doesn’t — Swisse genuinely owns “best in-pharmacy availability,” and that matters for some buyers.

Comparison Table: 8 Anti-Aging Supplements in Australia

Prices verified May 2026 from manufacturer websites and Chemist Warehouse listings. Prices may vary; check the seller for current pricing.

#1 — Eternal Elixir NMN 500mg | Best Overall NAD+ Booster

Quick take. Best NMN in Australia. Pure. Strong dose. Great price.

Key Specs: 500mg pure nicotinamide mononucleotide per capsule · 90 capsules per bottle · ≥99% purity (third-party tested) · Australian-warehoused · $74.95 AUD ($0.83/dose).

Nicotinamide mononucleotide (NMN) sits at the centre of modern anti-aging science because it is the closest precursor your cells turn into NAD+. NAD+ drives sirtuins. It drives DNA repair. It drives mitochondrial energy.. According to PubMed, a 2022 review in Molecular Biology Reports by Soma and Lalam ([DOI](https://doi.org/10.1007/s11033-022-07459-1)) summarised that systemic NAD+ decline correlates with virtually every hallmark of aging, and that NMN supplementation has shown therapeutic potential across diabetes, cardiovascular issues, and cognitive decline in human trials.

Eternal Elixir’s NMN delivers a clinically meaningful 500mg per single capsule, validated to ≥99% purity by third-party laboratory testing. The 90-capsule bottle is the formula’s structural advantage: most Australian competitors stop at 60 capsules at the same price point. This means 50% more doses per bottle. At 1g daily (Sinclair-protocol dosing of two capsules), a bottle lasts 45 days — versus 30 days for a 60-capsule competitor.

Pros: Highest-purity third-party-tested NMN available in Australia, clinically meaningful single-capsule dose, 90-capsule bottle delivers 50% more product than typical competitors, locally warehoused for fast dispatch, free shipping over $100 AUD.

Cons: NMN is intrinsically expensive globally — even at $0.83/dose this is the highest absolute spend in our top 4. People sensitive to capsule fillers should note this is HPMC vegetable capsule (non-animal).

Best for: Anyone over 35 starting their first serious longevity stack. NMN should be the foundation; everything else stacks on top.

Where to buy: eternalelixir.com.au/product/nmn-capsules — $74.95 AUD, ships from Australia in 2–4 business days.

#2 — Eternal Elixir Trans-Resveratrol 1200mg | Best Sirtuin Activator

Quick take. Top sirtuin support. High dose. Pairs with NMN.

Key Specs: 1200mg trans-resveratrol per capsule (98% trans isomer from Japanese knotweed) · 90 capsules · $59.95 AUD ($0.67/dose).

Trans-resveratrol is the active polyphenol that activates SIRT1 — the longevity gene that NAD+ powers. Dr David Sinclair’s personal protocol pairs 1g resveratrol with 1g NMN daily, taken with a fat source for absorption. The “trans” isomer matters: many cheap resveratrol products contain the inactive cis isomer, with only 50% trans content. Eternal Elixir specifies 98% trans-resveratrol — the highest-grade material on the Australian market.

The 1200mg per capsule is intentional: it slightly exceeds Sinclair’s 1g target in a single capsule, eliminating the need to swallow multiple capsules. Compare this to Swisse Resveratrol+ (#6 on our list), which delivers approximately 120mg per capsule — ten times less. At 1200mg, Eternal Elixir is the only mainstream Australian brand reaching the dose used in longevity clinical research.

Pros: 98% trans-resveratrol purity, dose matches Sinclair Protocol research benchmarks, 90 capsules at $59.95 = $0.67/dose (cheapest clinical dose in Australia), pairs natively with EE NMN.

Cons: Must be taken with fat for meaningful absorption — empty-stomach use is largely wasted. Dark capsule colour (resveratrol pigment) can mark countertops if spilled.

Best for: Anyone running the Sinclair Protocol, or already supplementing NMN and looking to amplify sirtuin activation. Take alongside NMN with breakfast that contains fat (yoghurt, eggs, MCT, avocado).

Where to buy: eternalelixir.com.au/product/resveratrol-capsules — $59.95 AUD, free shipping over $100.

#3 — Eternal Elixir Spermidine 10mg | Best Autophagy Inducer

Quick take. Strong autophagy push. Clean formula. Daily use.

Key Specs: 10mg spermidine per capsule (wheat germ extract, naturally bound) · 90 capsules · $59.95 AUD ($0.67/dose).

Spermidine is the polyamine that triggers autophagy — your cells’ built-in waste-clearance and recycling system. Without functional autophagy, damaged proteins and dysfunctional mitochondria accumulate, which is mechanistically linked to virtually every age-related disease. According to PubMed, Madeo and colleagues described spermidine in Autophagy (2018, [DOI](https://doi.org/10.1080/15548627.2018.1530929)) as a “physiological autophagy inducer acting as an anti-aging vitamin in humans,” noting that endogenous spermidine declines with age and that increased dietary spermidine intake associates with reduced cardiovascular and cancer mortality.

Eternal Elixir’s spermidine is sourced from wheat germ extract — the form used in nearly all human spermidine clinical trials, including the SmartAge cognitive trial. At 10mg per capsule and 90 capsules per bottle, this is a 90-day supply at the standard 10mg daily dose — three times longer than typical 30-capsule competitors. For Australians, this is the cheapest research-grade spermidine available, full stop.

Pros: Wheat-germ-derived (matches the form used in published human trials), 10mg single-capsule dose meets clinical research benchmarks, 90-day supply per bottle, no synthetic spermidine.

Cons: Wheat-germ source is unsuitable for severe coeliac disease sufferers (gluten cross-contamination risk despite extraction process). Effects are subtle and accumulate over months — this is not a stimulant supplement.

Best for: Autophagy-focused stacks, anyone past 40 who wants cellular cleanup mechanisms supported, fasting practitioners (spermidine extends the autophagic effect of intermittent fasting).

Where to buy: eternalelixir.com.au/product/spermidine-capsules — $59.95 AUD.

#4 — Eternal Elixir Ca-AKG 500mg | Best for Biological Age

Quick take. Targets biological age. Solid dose. Good value.

Key Specs: 500mg calcium alpha-ketoglutarate per capsule · 90 capsules · $49.95 AUD ($0.55/dose — cheapest per-dose on this list).

Calcium alpha-ketoglutarate (Ca-AKG) is the supplement form of α-ketoglutarate, a metabolite of the citric acid cycle that has emerged as one of the most credible anti-aging compounds based on epigenetic-age data. According to PubMed, a 2022 review in Aging Cell by Johnson, English, Sinclair and colleagues ([DOI](https://doi.org/10.1111/acel.13664)) identified alpha-ketoglutarate among the specific molecules associated with reductions in epigenetic age in human studies — alongside metformin and vitamin D3.

The 2021 TruDiagnostic/Ponce de Leon Health pilot trial reported an average 8-year reduction in biological age (DNA-methylation-based) in participants taking AKG over seven months. While replication trials are still ongoing, AKG’s safety profile and metabolic familiarity make it one of the lowest-risk longevity additions you can make.

Eternal Elixir’s Ca-AKG delivers 500mg per capsule, the dose used in the original human pilot data, in. The 90-capsule bottle lasts three months at 1g daily. At $0.55 per 500mg dose, it’s the cheapest per-dose AKG product available in Australia.

Pros: Cheapest per-dose AKG in Australia, calcium-bound form for stomach tolerability, 90-capsule bottle (most competitors are 60), strongest emerging biological-age evidence on this list.

Cons: Newer to the longevity stack discussion than NMN/resveratrol — fewer practitioners have direct experience guiding dosing. Not a “feel-it” supplement; effects are slow and only measurable via biological-age testing.

Best for: Quantified-self users tracking epigenetic age (TruAge, GlycanAge), anyone over 40 building a comprehensive longevity stack, fans of the David Sinclair / Aubrey de Grey / Andrew Steele school of biological-age intervention.

Where to buy: eternalelixir.com.au/product/ca-akg-capsules — $49.95 AUD.

#5 — Bulk Nutrients NMN Capsules | Best Budget Bulk-Order NMN

Quick take. Cheap. Bulk packs. Lower per-cap dose.

Where to buy: Bulk Nutrients NMN Capsules (official site)

Key Specs: 250mg NMN per capsule · 60 capsules · $59.00 AUD ($0.98 per 500mg dose).

Bulk Nutrients is one of Australia’s largest direct-to-consumer supplement brands and their NMN product gives the local market a credible second option to Eternal Elixir. The product is third-party tested, manufactured in Australia, and ships from Tasmania.

The trade-offs: at 250mg per capsule, you’ll need two capsules to reach a clinically relevant 500mg dose, and four to match Sinclair’s 1g protocol. At $59 for the smaller bottle (= 30 doses of 500mg), Bulk’s per-500mg-dose cost is $0.98. That is about 18% pricier per equivalent dose than our brand. Bulk also doesn’t pair NMN with adjacent longevity products (no resveratrol, no spermidine, no Ca-AKG), so it’s not a one-stop longevity stack.

Pros: Australian manufacturer, third-party tested, established brand reputation, often runs sale pricing.

Cons: Smaller per-capsule dose forces you to swallow more capsules, more expensive per-equivalent-dose than EE, no companion longevity products for stacking.

Best for: Existing Bulk Nutrients customers consolidating to a single brand, people who specifically want lower-dose flexibility (e.g., 250mg titration).

#6 — Swisse Resveratrol+ | Best Pharmacy Availability

Quick take. Found in pharmacies. Modest dose. Brand trust.

Where to buy: Swisse Resveratrol+ (official site)

Key Specs: Approximately 120mg trans-resveratrol per capsule plus B-vitamins · 30 capsules · $39.99 AUD at Chemist Warehouse.

Swisse genuinely owns the Australian pharmacy shelf for resveratrol — you can walk into any Chemist Warehouse, Priceline or Coles pharmacy and buy this off the shelf. For some buyers (older parents, gift purchases, no-online-shopping households), that pharmacy availability is worth more than perfect dosing.

The honest critique: at ~120mg trans-resveratrol per capsule, this is roughly one-tenth the dose used in longevity research. It’s better classified as a general antioxidant with a B-complex than a serious anti-aging intervention. Per-mg cost is the highest on this list once you adjust for actual resveratrol content.

Pros: In every Australian pharmacy, well-known brand, formulated with B-vitamins for general wellness, 30-day moneyback at most retailers.

Cons: Sub-clinical resveratrol dose, contains additional ingredients you may not want, expensive per mg of active resveratrol.

Best for: Pharmacy-only buyers, people who want a “wellness” supplement rather than a research-dose longevity intervention, gift purchases.

#7 — Life Extension GEROPROTECT Longevity A.I. | Best Imported Senolytic Blend

Quick take. Imported blend. Senolytic angle. Premium price.

Where to buy: Life Extension GEROPROTECT Longevity A.I. (official site)

Key Specs: Multi-ingredient blend (quercetin, ginger root, fisetin proxies) · 30 capsules · ~$78 AUD via iHerb AU.

Life Extension is the legacy US longevity supplement brand. Their GEROPROTECT Longevity A.I. blend was algorithmically designed to mimic gene expression patterns associated with longer-lived organisms and includes quercetin and ginger compounds with senolytic activity (clearing senescent “zombie” cells).

Practical reality: importing from iHerb to Australia adds 7–14 days shipping, GST is added at the cart, and at $78 AUD per 30-day bottle this is the most expensive product on our list per dose. The proprietary blend means exact mg of each active is not disclosed — a transparency disadvantage compared to single-ingredient products.

Pros: Established US brand with deep R&D, novel multi-mechanism formulation, includes senolytic compounds not found in other entries on this list.

Cons: Expensive per dose, slow shipping to Australia, proprietary blend obscures exact dosing of actives, not Australian-warehoused.

Best for: Experienced biohackers already running NMN+resveratrol who want to layer in senolytic compounds, people willing to pay premium for a brand-name imported product.

#8 — Herbs of Gold AstaPure Astaxanthin | Best Single-Ingredient Antioxidant

Quick take. Single antioxidant. Algae-sourced. Easy add-on.

Where to buy: Herbs of Gold AstaPure Astaxanthin (official site)

Key Specs: 12mg natural astaxanthin per capsule (Haematococcus pluvialis algae) · 60 capsules · $59.95 AUD.

Astaxanthin is the carotenoid pigment that makes salmon pink and is one of the most potent fat-soluble antioxidants on earth — protecting cell membranes and mitochondria from oxidative damage. While astaxanthin is not a longevity-pathway intervention like NMN or resveratrol, it sits well in an anti-aging stack as a skin-, eye- and mitochondrial-protection compound.

Herbs of Gold’s AstaPure uses 12mg of algae-sourced natural astaxanthin (synthetic astaxanthin is significantly less bioactive and should be avoided). This is one of the highest doses available in Australian pharmacy distribution.

Pros: 12mg dose at the upper end of clinical research, natural algae source, well-distributed in Australian health stores, vegetarian.

Cons: 60-capsule format means a 60-day supply (vs EE’s 90), addresses a different mechanism than the longevity-pathway products higher on this list.

Best for: Skin-aging and eye-health focused stackers, athletes adding mitochondrial protection, anyone wanting a single-ingredient antioxidant to add to a longevity stack.

How We Evaluated These Anti-Aging Supplements

Our scoring methodology weights criteria toward what actually moves the needle for Australian longevity buyers — not the manufactured “best of” listicles ranked by affiliate margin.

Quality and purity (30%) — third-party laboratory testing, specified isomer content (e.g., 98% trans-resveratrol vs unspecified mixes), source documentation (e.g., wheat-germ vs synthetic spermidine), and absence of unnecessary fillers.

Australian availability and shipping (20%) — local warehousing, dispatch speed, free-shipping thresholds, and whether the product is reliably re-stocked. Imports lose points for 7–14 day delivery windows.

Price per dose in AUD (20%) — calculated on actual clinical dose, not bottle-shelf price. Products that force you to swallow 4 capsules to reach the studied dose lose ground here.

Product range for stacking (15%) — can you build a complete longevity protocol from one brand without paying multiple shipping fees? Eternal Elixir’s 19-product catalogue scores top here; single-product brands lose ground.

Customer reviews and reputation (15%) — independent review aggregation across ProductReview.com.au, Trustpilot, and Reddit longevity communities.

How to Build an Anti-Aging Stack — Beginner to Advanced

Beginner stack (foundation): Eternal Elixir NMN 500mg (1 cap morning) + Eternal Elixir Trans-Resveratrol 1200mg (1 cap morning with fat). This is the Sinclair Protocol at a clinically meaningful dose. Total: ~$135 AUD/month, free shipping.

Intermediate stack (autophagy layer): Add Eternal Elixir Spermidine 10mg (1 cap any time of day). The combination of NAD+ raising, sirtuin activation, and autophagy induction covers three of the major aging hallmarks. Total: ~$195 AUD/month.

Advanced stack (biological-age intervention): Add Eternal Elixir Ca-AKG 500mg (1–2 caps daily) for epigenetic-age impact. Optionally layer in a senolytic blend like Life Extension GEROPROTECT during a quarterly “senolytic week” rather than continuously. Track biological age every 6 months via TruAge or GlycanAge to confirm the stack is working.

Frequently Asked Questions

What is the best anti-aging supplement in Australia?

Eternal Elixir NMN 500mg is our top pick. It raises NAD+ directly. NAD+ drives every major longevity pathway. at a competitive AUD price point of $0.83 per dose with 90 capsules per bottle and free Australian shipping over $100. For sirtuin activation, pair it with Eternal Elixir Trans-Resveratrol 1200mg following the Sinclair Protocol.

Where can I buy anti-aging supplements in Australia?

The most reliable Australian sources are direct from manufacturer websites such as eternalelixir.com.au (locally warehoused, free shipping over $100), bulknutrients.com.au, or Chemist Warehouse for mainstream brands like Swisse. Imported premium options like Life Extension are available via iHerb AU, though shipping takes 7–14 days versus 2–4 days for locally stocked products.

Do anti-aging supplements actually work?

Research suggests several compounds — including NAD+ precursors, spermidine and alpha-ketoglutarate — can influence biological aging markers in human studies. According to PubMed, a 2024 Cell Metabolism review by Guarente, Sinclair and Kroemer ([DOI](https://doi.org/10.1016/j.cmet.2023.12.007)) covered eight clinically tested anti-aging compounds with promising data. They are not a substitute for diet, sleep and exercise — but stack on top for compounding effects.

What is the Sinclair Protocol?

The Sinclair Protocol refers to Harvard geneticist Dr David Sinclair’s personal longevity stack centred on NMN (1g daily) plus trans-resveratrol (1g daily) taken with a fat source. NMN raises NAD+ levels which sirtuins require, and resveratrol activates those sirtuins. Eternal Elixir’s NMN 500mg and Trans-Resveratrol 1200mg are formulated to deliver this protocol at Australian pricing.

How much do anti-aging supplements cost in Australia?

Quality anti-aging supplements in Australia range from approximately $40 AUD for basic resveratrol up to $120+ AUD for premium NAD+ stacks. Eternal Elixir products sit in the $49.95–$74.95 AUD range with 90 capsules per bottle, working out to roughly $0.55–$0.83 per dose — significantly cheaper per-dose than 60-capsule competitors at the same shelf price.

Can I take NMN, resveratrol and spermidine together?

Yes — these three compounds target different but complementary pathways: NMN raises NAD+, resveratrol activates sirtuins, and spermidine triggers autophagy (cellular clean-up). They are commonly stacked in longevity protocols. Take NMN and resveratrol together in the morning with a fat source for absorption, and spermidine can be taken at any time of day.

Is NMN or NR better for anti-aging?

Both raise NAD+ levels effectively in human studies. NMN is one biosynthetic step closer to NAD+ in the cell and has more clinical trial data behind specific anti-aging endpoints. NR has a longer commercial history and is well-tolerated. For Australians prioritising cost-per-dose and clinical depth, NMN at 500mg is generally the better starting point. See our deeper comparison: NMN vs NR: the Australian verdict.

What dose of resveratrol is needed for anti-aging benefits?

Most longevity researchers including Dr David Sinclair use 1000mg of trans-resveratrol daily. Eternal Elixir’s 1200mg formula slightly exceeds this benchmark in a single capsule. Always take with a fat source (yoghurt, MCT oil, or a meal containing fat) to dramatically improve absorption — resveratrol bioavailability is poor when taken on an empty stomach.
