Best Pterostilbene Supplements in Australia 2026: 7 Trans-Pterostilbene Brands Compared

Last updated: September 28, 2026 · Originally published: April 30, 2026 · By Eternal Elixir Editorial

Quick answer: The best pterostilbene supplement in Australia for most buyers is Eternal Elixir Trans-Pterostilbene 500mg. Each capsule holds 500mg of trans-pterostilbene, the most per capsule of the seven products compared here, and a 90-capsule bottle costs $64.99, or $0.72 a day at the label serve of one capsule. That works out at $0.14 per 100mg of pterostilbene, the lowest in this list by a wide margin, and orders ship from Sydney within 24 hours. If you want the cheapest bottle, Pristine’s 100mg capsules cost $34.82 for 60. If you would rather stay inside the doses used in published human trials, a 100mg or 150mg product such as Double Wood or NusaPure fits that better than a 500mg capsule.

Eternal Elixir makes Trans-Pterostilbene 500mg. It is our pick, and every figure for the other six products comes from their own product page or the Australian store we link, checked in September 2026. We have not lab-tested any of them. If you are still deciding between the two stilbenes, start with our pterostilbene vs resveratrol comparison. This page is for buyers who have picked pterostilbene and now need to choose a product.

Comparison table: best pterostilbene supplements in Australia 2026

All prices are in AUD, as of Sep 2026. “Cost per serve” divides the price by the number of servings the label directs. “Cost per 100mg” divides it by the total pterostilbene in the pack, which is the fairest way to compare a 50mg capsule with a 500mg one.

Our price is from our live product page. Competitor prices were read from the linked pages in September 2026 and move with promotions and exchange rates, so check before you buy. “Not stated” means the listing we checked does not say whether the pterostilbene is the trans form.

How we ranked these pterostilbene supplements

Eternal Elixir makes the product at #1, so read this before you trust the order. We put our capsules first on three label facts: the most pterostilbene per capsule (500mg), the lowest cost per 100mg of pterostilbene ($0.14), and the most pterostilbene in one pack (45 g across 90 capsules). The table also shows where other products beat ours, and we have kept those labels on them. Pristine’s has the lowest price per serve and per bottle, and the 100mg and 150mg products sit inside the dose range that human trials have tested, which our 500mg serve does not.

We ordered the other six on four questions:

• How much pterostilbene is in a serve, and does the label name the trans form? The published human trials used trans-pterostilbene, so a label that says so tells you more than one that does not.
• What does 100mg of pterostilbene cost? Bottle prices hide a tenfold spread in dose, from 50mg to 500mg a serve.
• Is the product mostly pterostilbene? Combination formulas rank lower when pterostilbene is the minor ingredient.
• Can you buy it from an Australian store? Two of the cheaper listings ship from the United States through Amazon AU, which means a longer wait than a local order.

1. Eternal Elixir Trans-Pterostilbene 500mg: our pick

Label facts: 500mg trans-pterostilbene per capsule · 90 capsules per bottle · take 1 capsule daily · other ingredients: rice flour and a cellulose capsule · $64.99 · ships from Sydney within 24 hours.

This is the highest-dose pterostilbene capsule we found on sale to Australians, and the bottle holds 90 capsules where four of the five other capsule products hold 60. One bottle gives you 45 g of pterostilbene. The next largest amount in this list is Switch Nutrition’s tub at 21 g, and the 60-capsule 100mg bottles hold 6 g each. That is why our cost per 100mg lands at $0.14, less than half that of any other product in the table.

The label is short: pterostilbene, rice flour and the capsule shell. There is no blend to decode and no second active taking up space in the capsule. The product page also says you can ask for the current batch certificate of analysis.

The honest caveat is the dose. The human trials we cite below used 50mg to 250mg of pterostilbene a day, and the best-known safety trial stopped at 250mg a day for six to eight weeks. Our label serve of one 500mg capsule is twice that, so those trials do not cover our serve directly. If that matters to you, a 100mg or 150mg product is the more conservative choice, and we say so again in the verdict.

Who it suits: buyers who want the most pterostilbene per dollar, people who prefer a single-ingredient label, and anyone already buying our NMN or resveratrol who wants one order and one delivery.

Who it doesn’t suit: anyone who wants to stay within the doses tested in human trials, and anyone who wants resveratrol and pterostilbene in a single product (see Switch Nutrition below).

Buying ahead: on the product page two bottles save 10%, three save 15% and five save 20%, and orders over $100 ship free.

2. Switch Nutrition Resveratrol+: the most pterostilbene per serve after ours

Label facts: 30g powder · one 500mg scoop gives 350mg trans-pterostilbene and 150mg trans-resveratrol · 60 serves · 1 serve a day with food · $69.95 direct from Switch Nutrition.

Older guides, including an earlier version of this one, described this powder as a resveratrol product with a token amount of pterostilbene. The current label says otherwise: 70% of each scoop is pterostilbene. At 350mg a serve it is the closest product here to our dose, and at $0.33 per 100mg of pterostilbene it is the second-cheapest way to buy the compound in this list.

The trade-offs are the format and the second ingredient. You measure a small 500mg scoop rather than swallow a capsule, and you get 150mg of resveratrol whether you want it or not. The label says it is not recommended for children under 15 or for pregnant or breastfeeding women.

Who it suits: people who want both stilbenes in one daily serve and don’t mind a powder. Who it doesn’t: anyone who wants pterostilbene on its own, or a capsule.

3. NusaPure Pterostilbene 150mg: a 90-day bottle at a trial-range dose

Label facts: 150mg pterostilbene per 2-capsule serve · 180 vegetarian capsules · 90 serves · directions: 2 capsules daily, preferably with meals · $58.35 on Amazon AU (shipped from Amazon US) or $89.95 from Bodytonix.

NusaPure sells the only other 90-serve pack in this list. At 150mg a day its serve sits inside the 100mg to 250mg range used in the Riche trials, and at the Amazon AU price it costs $0.65 a serve. The listing does not say whether the pterostilbene is the trans form, and the two-capsule serve means 180 capsules to get through rather than 90. The Amazon AU price is for stock sent from the United States. Bodytonix sells the same product from Australia at a higher price.

Who it suits: buyers who want a moderate daily dose and a three-month bottle. Who it doesn’t: anyone who wants the trans form named on the label, or local delivery at the lower price.

4. Double Wood Pterostilbene 100mg: a familiar 100mg capsule

Label facts: 100mg pterostilbene per capsule · 60 capsules · $59.95 from Bodytonix, whose listing directs 1 capsule a day · $35.11 on Amazon AU, shipped from Amazon US, whose listing directs one serving once or twice a day.

Double Wood is a US brand that many longevity buyers already know, and this is a plain 100mg capsule. The Amazon listing says it is third-party tested and made in the USA, and it lists gelatin among the other ingredients, which matters if you avoid animal products.

The price depends on where you buy. From Bodytonix, an Australian store, it is $1.00 a capsule. From Amazon AU it is about $0.59 a capsule, but the bottle ships from the United States.

Who it suits: first-time buyers who want a well-known brand at a trial-range dose. Who it doesn’t: vegetarians, and anyone comparing on cost per 100mg, where it sits well behind the higher-dose products.

5. Pristine’s Pterostilbene 100mg: lowest price per serve

Label facts: 100mg pterostilbene per capsule · 60 capsules · one capsule a day · $34.82 from Nutricity, which ships from Perth.

This is the cheapest bottle and the cheapest daily serve in the list, at $0.58 a capsule. The listing says it is third-party tested and made in the USA. It does not name the trans form, and there is less published detail about this brand than about the others here. Nutricity quotes 3 to 6 days for delivery within Australia.

Who it suits: budget buyers who want a low daily dose. Who it doesn’t: anyone paying by the milligram. At $0.58 per 100mg it costs about four times as much per milligram of pterostilbene as our 500mg capsule.

6. Jarrow Formulas trans-Pterostilbene: the ingredient used in the Riche trials

Label facts: 50mg trans-pterostilbene (as pTeroPure) per capsule · 60 vegetarian capsules · 1 capsule a day · $43.67 from Ausherb.

Jarrow’s capsule uses pTeroPure, a branded trans-pterostilbene. The 2014 report of the Riche trial says its pterostilbene was supplied as pTeroPure, described as more than 99% all-trans-pterostilbene. If you want the same ingredient as the best-known human trial, this is it, although at 50mg its label serve is half the trial’s lowest daily dose of 100mg.

The label tells anyone with a medical condition (it names people being treated for blood glucose control), anyone pregnant, breastfeeding or trying to conceive, anyone under 18 and anyone taking medication to check with a health professional first. Mega Vitamins also lists this product but showed it out of stock when we checked.

Who it suits: buyers who want a named, trial-linked ingredient at a low dose. Who it doesn’t: anyone comparing on cost per 100mg, where it is $1.46 against our $0.14.

7. Dr. Mercola Quercetin and Pterostilbene: a combination formula

Label facts: each 2-capsule serve gives 500mg quercetin phytosome complex (34% quercetin) and 50mg trans-pterostilbene · 60 capsules · 30 serves · $90.62 from Mega Vitamins.

This is a quercetin product first. Pterostilbene is the smaller ingredient at 50mg a serve, and at $6.04 per 100mg it is the most expensive way in this list to buy pterostilbene. Buy it for the quercetin phytosome, not as your main pterostilbene source.

Who it suits: people who already want quercetin and like one combined product. Who it doesn’t: anyone buying for the pterostilbene.

What the research on pterostilbene shows, and what it does not

Pterostilbene is a close chemical relative of resveratrol. Two of resveratrol’s hydroxyl groups are methoxy groups in pterostilbene, which makes the molecule more fat-soluble and slower to be broken down. Reviews of the research describe this higher bioavailability as its main advantage over resveratrol (Estrela et al., 2013). Most of the antioxidant research summarised in those reviews is cell and animal work (McCormack and McFadden, 2013).

The figure most guides quote, “80% versus 20%”, comes from rats. In a 2011 study, rats were given the two compounds by mouth for 14 days, and about 80% of the pterostilbene dose reached the bloodstream against about 20% of the resveratrol (Kapetanovic et al., 2011). We found no equivalent head-to-head measurement in people, so treat the figure as the reason pterostilbene is interesting, not as a number that applies to you.

The human evidence is small. The main trial (Riche et al.) enrolled 80 adults whose total or LDL cholesterol was above set cut-offs. They took 50mg twice a day, 125mg twice a day, 50mg with grape extract, or a placebo for six to eight weeks.

• Safety: the 2013 report found no adverse effects on liver, kidney or blood glucose markers and no significant self-reported side effects. The authors concluded that pterostilbene is generally safe for use in humans up to 250mg a day.
• LDL cholesterol: the 2014 report found that LDL rose by 17.1 mg/dL (about 0.44 mmol/L) in people taking pterostilbene on its own. The rise was not seen in the group taking it with grape extract, and it appeared smaller in people already taking cholesterol medicine.
• Blood pressure: in the 250mg-a-day group, systolic blood pressure fell by 7.8 mmHg and diastolic by 7.3 mmHg. This was a short trial in 80 people, so it is a finding to watch rather than a reason to take pterostilbene.

A second trial combined pterostilbene with nicotinamide riboside (NR), an NAD+ precursor. In 120 adults aged 60 to 80, a daily 250mg of NR plus 50mg of pterostilbene raised whole-blood NAD+ by about 40% after four weeks, and double that dose raised it by about 90%, with the rise holding through eight weeks (Dellinger et al., 2017). The company that sells the combination funded the trial, and the design cannot tell you what pterostilbene does on its own. LDL cholesterol also rose slightly in the treated groups.

What has not been shown: there is no long-term human trial of pterostilbene, most of the brain and ageing research is in animals, and a 2018 review found that human trials so far, all using resveratrol, have not shown a benefit for memory or thinking (Lange and Li, 2018). The review’s authors call for long-term human trials of both compounds.

How much pterostilbene should you take a day?

The published human trials used 50mg to 250mg a day. The labels in this list direct anywhere from 50mg (Jarrow) to 500mg (ours) per daily serve. Follow the label on the product you buy and don’t take more than it directs.

Our label serve is one 500mg capsule a day, which is above the highest dose in the Riche safety trial. We state that plainly because it is the main reason a buyer might choose one of the 100mg or 150mg products instead. If you want the most pterostilbene for your money, ours is the better buy. If you want to stay within tested amounts, choose a lower-dose product. For the related compound, our resveratrol dosage guide covers how much to take and when.

Who should check with a doctor first

• Anyone taking prescription medicine, especially for cholesterol or blood pressure, because the Riche trial saw changes in both.
• Anyone who has been told their LDL cholesterol is high, given the LDL rise seen in that trial.
• Anyone taking medicine to manage blood glucose. Jarrow’s label names this group.
• Pregnant or breastfeeding women and anyone under 18. The trials did not include them, and the Jarrow and Switch Nutrition labels tell these groups to avoid the product or get advice first.

Stop taking it and speak to your doctor if you notice anything unusual after you start.

Pterostilbene vs resveratrol: which to buy

Buy pterostilbene if you want the compound that is absorbed better in animal studies and comes in smaller daily amounts. Buy resveratrol if you want the compound with far more human research behind it, most of it at much larger daily amounts. Many people take both. Our Trans-Resveratrol 1200mg label serve is two capsules (1,200mg) a day, with or without food, and our resveratrol supplement comparison ranks it against other brands sold in Australia.

Stacking pterostilbene with NMN and spermidine

The usual reason to pair pterostilbene with an NAD+ precursor is the reasoning behind the NR trial above: the precursor raises NAD+, and stilbenes are studied in the lab for their effect on sirtuins, the enzymes that use it. The only human data for a pterostilbene pairing come from that NR trial. No trial has tested NMN with pterostilbene, so that pairing rests on the reasoning, not on a result. Our NMN and resveratrol guide covers the same logic for resveratrol.

If you want to try it, the simplest combination from our range is one Trans-Pterostilbene capsule and one NMN 500mg capsule a day, each at its label serve. The two bottles come to $124.98 for 90 days, which clears the $100 free-shipping line.

If you also want spermidine, the Cellular Longevity Stack ($139.99) already contains our NMN, spermidine and trans-pterostilbene, so don’t buy it together with a separate pterostilbene bottle. Our guide to building a longevity stack and our longevity stack comparison explain how the pieces fit together.

What to check on a pterostilbene label in Australia

• The trans form. The human trials used trans-pterostilbene. Three labels in our list do not say which form they contain.
• Milligrams per serve, not per capsule. NusaPure’s 150mg serve takes two capsules, and so does Dr. Mercola’s 50mg.
• Total pterostilbene in the pack. Multiply the serve by the number of serves. Our bottle holds 45 g, the 60-capsule 100mg bottles hold 6 g, and Jarrow’s holds 3 g.
• Other actives. Combination products can make pterostilbene the minor ingredient.
• Where it ships from. The lower Amazon AU prices on some of these products are for stock sent from the United States.
• Fillers and capsule material. Look for a short ingredient list, and check for gelatin if you avoid animal products.

Our guide to reading an Australian supplement label for fillers and fake dosages covers the same checks for any product.

Add Trans-Pterostilbene 500mg to cart · $64.99

Where can I buy pterostilbene in Australia?

Mostly from brand and retailer websites. In this comparison that means Eternal Elixir (ships from Sydney), Switch Nutrition’s own store, Bodytonix (Double Wood and NusaPure), Nutricity (Pristine’s, ships from Perth), Ausherb (Jarrow) and Mega Vitamins (Dr. Mercola). Amazon AU also lists Double Wood and NusaPure, shipped from Amazon US.

Is pterostilbene better than resveratrol?

In rats, far more of it reaches the bloodstream: about 80% of an oral dose against about 20% for resveratrol. Resveratrol has much more human research. Neither has long-term human trial evidence for ageing outcomes, and many people take both. Our pterostilbene and resveratrol comparison goes through the evidence in detail.

How much pterostilbene should I take a day?

Follow your product’s label. Human trials have used 50mg to 250mg a day for up to eight weeks, and the labels in this list direct 50mg to 500mg a day. Our 500mg serve is above the highest trial dose, so choose a 100mg or 150mg product if you want to stay within tested amounts.

Is pterostilbene safe to take every day?

In the 80-person Riche trial, up to 250mg a day for six to eight weeks caused no adverse effects on liver, kidney or glucose markers, though LDL cholesterol rose in people taking pterostilbene alone. There are no long-term human safety data. Talk to your doctor first if you take prescription medicine, are pregnant or breastfeeding, or are under 18.

Can I take pterostilbene with NMN?

Many people do, each at its own label serve. The human trial of a pterostilbene pairing used nicotinamide riboside, not NMN, and showed a rise in blood NAD+ levels. No trial has tested NMN with pterostilbene. Our range sells both, and the Cellular Longevity Stack combines them with spermidine.

Does pterostilbene cross the blood-brain barrier?

Research reviews, drawing mostly on animal studies, report that both pterostilbene and resveratrol cross it. That does not show a benefit for memory or thinking in people, and the human trials so far have used resveratrol without showing one.

How much does pterostilbene cost in Australia?

In our September 2026 check, bottles ranged from $34.82 (Pristine’s, 60 capsules of 100mg) to $90.62 (Dr. Mercola, a quercetin combination). Per 100mg of pterostilbene, costs ranged from $0.14 (Eternal Elixir) to $6.04 (Dr. Mercola). Cost per 100mg is the fairer comparison when doses differ tenfold.

The verdict: which pterostilbene supplement should you buy?

For most buyers: Eternal Elixir Trans-Pterostilbene 500mg. It has the most pterostilbene per capsule and per bottle and the lowest cost per 100mg in this list, and it ships from Sydney within 24 hours.

For resveratrol and pterostilbene in one serve: Switch Nutrition Resveratrol+.

For a dose inside the tested range: NusaPure 150mg or Double Wood 100mg.

For the lowest bottle price: Pristine’s 100mg.

For the ingredient used in the best-known trial: Jarrow’s pTeroPure capsules.

If you already buy NMN or resveratrol from us: add Trans-Pterostilbene to the same order. Two bottles save 10%, three save 15%, and orders over $100 ship free.
