Last updated: 27 August 2026 · By Eternal Elixir Editorial · 6 products compared

Searching for Double Wood supplements Australia usually ends the same way: you find the brand on a US site or a marketplace listing, the sticker price looks reasonable, and then the currency conversion and international freight arrive. Double Wood is a well-known American supplement company with a large catalogue and a loyal following, but it does not run an Australian storefront, and its prices are set in US dollars.

This guide compares Double Wood against five TUDCA options an Australian can actually buy in AUD, ranked on cost per 500mg serve, local availability, dose depth and reputation. Every price below was read directly from the seller on 27 August 2026. If you want the wider category view first, start with our complete guide to the best TUDCA supplements in Australia.

Double Wood does not sell directly in Australia; Australian buyers pay in US dollars and wait on international shipping, so locally stocked TUDCA is usually cheaper and faster.

Key numbers:

• Cheapest TUDCA per 500mg serve in this comparison: $0.67 (Eternal Elixir, $59.99 for 90 capsules)
• Dearest AUD-priced option: $3.33 per 500mg (Nutricost 500mg, 30 capsules, $99.95)
• That is a 4.9x spread between the cheapest and dearest AUD-priced products on the same 500mg unit
• Double Wood’s listed price is US$27.95 per bottle, set in US dollars and dispatched from the United States

Double Wood alternatives in Australia compared on cost per 500mg

The best Double Wood alternatives in Australia separate on one number, so every row is normalised to the same unit: AUD cost per 500mg of TUDCA. That matters because pack sizes and capsule strengths differ wildly in this category, and a 250mg capsule at a low sticker price is not the bargain it looks like next to a 500mg capsule.

Prices read from each seller on 27 August 2026 and will move with promotions. Two products are marked n/a because the seller does not publish a capsule count, so an honest per-serve figure cannot be calculated. Cost per 500mg assumes a single 500mg serving; check each label, since TUDCA dosage recommendations vary between brands.

#1. Eternal Elixir TUDCA 500mg — best overall value in Australia

Eternal Elixir TUDCA 500mg is the cheapest way to buy TUDCA in this comparison on a like-for-like basis. At $59.99 for a 90-capsule bottle with 500mg per capsule, a single daily capsule works out at $0.67 — roughly two-fifths of the next AUD-priced option and less than a quarter of the dearest.

The bottle size is the quiet advantage. Ninety capsules at one a day is three months of continuous use, where most competitors sell 30 or 60. That matters for a compound people typically take in blocks rather than for a week, and it removes two reorder cycles from the year.

Key specs: 500mg TUDCA per capsule, 90 capsules per bottle, one capsule per serving, third-party lab tested, dispatched from Australia within 24 hours on business days.

Pros:

• Lowest cost per 500mg serve of any product compared here at $0.67
• 90 capsules per bottle — three months at one capsule daily
• Full 500mg in a single capsule, so no doubling up
• Australian dispatch with free shipping over $100 and a 30-day money-back guarantee
• Sits alongside a deep longevity range if you are stacking

Cons:

• Certificates of analysis are supplied on request rather than published on the product page, so you have to email to see the batch certificate before ordering
• Only a handful of verified customer reviews on site, well behind the international brands
• No 30-capsule trial size if you want to test a small quantity first

Best for: Australians who want the lowest ongoing cost per serve, a full 500mg dose and local dispatch, and who are comfortable requesting a certificate of analysis rather than viewing one online.

Price: $59.99 AUD at Eternal Elixir. For how this fits a wider liver protocol, see our roundup of liver support supplements in Australia.

#2. Emrald Labs TUDCA — best lower-dose starting point

Emrald Labs TUDCA is an Australian-brand option carried by Elite Supps at $49.90 for 60 capsules of 250mg. On the shelf it is the cheapest bottle in this comparison, and for someone easing into TUDCA that lower per-capsule dose is a genuine feature rather than a compromise.

Normalised, though, the picture shifts. Sixty 250mg capsules is 15,000mg of TUDCA in total, so a 500mg serving costs $1.66 — about two and a half times the Eternal Elixir figure. The bottle is cheaper; the compound is not.

Key specs: 250mg TUDCA per capsule, 60 capsules per bottle, 60 serves at one capsule or 30 at two, Australian brand, widely stocked through Australian retail.

Pros:

• Lowest entry price of the AUD-priced products at $49.90
• 250mg capsules make it easy to start low or split a dose across the day
• Australian brand with established retail distribution
• Second-cheapest per 500mg of anything here

Cons:

• $1.66 per 500mg is roughly 2.5x the cost of the cheapest option
• Two capsules needed to reach the 500mg dose most protocols use
• 60 capsules is one month at a 500mg-equivalent daily dose

Best for: First-time TUDCA users who want a low entry price and a smaller capsule to titrate with. Our Elite Supps review for Australian buyers covers the retailer in more detail.

#3. Double Wood TUDCA — the best-known international name

Double Wood Supplements is the brand most people are searching for when they land on this page, and its reputation is deserved. It is a large American supplement company with an unusually broad single-ingredient catalogue, it publishes certificate-of-analysis imagery directly on its product listings, and it has accumulated a review base no Australian brand in this category comes close to.

Where it struggles is Australian logistics. The TUDCA listing is priced at US$27.95 and dispatched from the United States. That price is not directly comparable to the AUD figures in the table above: by the time an Australian buyer adds currency conversion, any card foreign-transaction fee and international shipping, the landed cost is materially higher than the sticker suggests, and delivery takes considerably longer than a domestic dispatch.

Double Wood also does not state a capsule count in its published product data, so we have not calculated a per-serve figure for it. There is no Double Wood Supplements Australia warehouse either, so every order is an international one.

Key specs: 250mg TUDCA per capsule, synthetic and not animal-derived, soy-free, gluten-free, non-GMO, priced in US dollars, shipped internationally.

Pros:

• Strong international reputation and by far the largest review base of any brand here
• Certificate-of-analysis imagery published openly on the listing
• Explicitly synthetic rather than bile-derived, which matters to a lot of buyers
• Very wide catalogue if you want to consolidate an order

Cons:

• No Australian storefront — you buy in USD and pay conversion plus international freight
• Long delivery times compared with a domestic dispatch
• Capsule count is not published in the product feed, so true cost per serve is hard to pin down before purchase
• Returns and support are handled from the United States

Best for: Buyers who specifically want the Double Wood label, already order from US supplement sites, and are relaxed about lead times and conversion costs.

#4. Body Essentials TUDCA 500 — best for two-capsule protocols

Body Essentials TUDCA 500 is sold through Supps247 at $169.95 for 60 capsules of 500mg. The listing is built around a 1,000mg daily intake — two capsules — which is a heavier protocol than most people need but is popular in the bodybuilding corner of this category.

At $2.83 per 500mg it is one of the dearest options in this comparison, and at the listing’s own suggested two-capsule intake a bottle lasts a month. It earns its place because it delivers a genuine 500mg per capsule from an Australian reseller, but the price premium is steep.

Key specs: 500mg TUDCA per capsule, 60 capsules, listing suggests 1,000mg per day, shipped by an Australian reseller.

Pros:

• Full 500mg per capsule
• Stocked and dispatched within Australia
• Suits users already running a higher two-capsule protocol

Cons:

• $2.83 per 500mg — more than four times the cheapest option here
• Only 30 days of supply at the intake the listing itself suggests
• Little published information about the manufacturer

Best for: Buyers committed to a 1,000mg daily protocol who want it from an Australian warehouse. Before going to that intake, read our guide to TUDCA side effects and safety.

#5. Nutricost TUDCA 500mg — best for a short trial run

Nutricost is another large American brand, but unlike Double Wood it reaches Australia through local resellers, which means you pay in AUD and receive a domestic dispatch. Supps247 lists the 500mg product at $99.95 for 30 capsules.

That is $3.33 per 500mg serve, the highest of any AUD-priced product in this comparison — you are paying a substantial importer margin for the convenience of local fulfilment. The 30-capsule pack does make it the lowest-commitment way to try a full 500mg dose without importing.

Key specs: 500mg TUDCA per capsule, 30 capsules, sold in AUD through an Australian reseller.

Pros:

• Full 500mg per capsule in a small, low-commitment pack
• Priced and shipped in Australia despite being a US brand
• Well-established international manufacturer

Cons:

• $3.33 per 500mg — the dearest AUD-priced option compared here
• Only 30 capsules, so a month at most
• Reseller pricing sits well above what the same brand costs in its home market

Best for: Someone who wants a genuine 500mg capsule, in AUD, in the smallest pack available, and is willing to pay for that. If you are wondering about availability more broadly, see whether TUDCA is sold at Chemist Warehouse.

#6. LVLUP Tudca Double Strength 500mg — best if you already use LVLUP

LVLUP Health has a following among Australian buyers who already use the brand’s other formulations, and Supps247 lists its Double Strength TUDCA at $139.95 with 500mg per capsule.

We have not calculated a cost per serve for it, because the listing does not state how many capsules are in the bottle. That is not a small omission at this price point, and it is the single reason it sits last here rather than mid-table. If you are considering it, ask the retailer for the capsule count before ordering and run the arithmetic yourself.

Key specs: 500mg TUDCA per capsule, capsule count not stated on the listing, sold through an Australian reseller.

Pros:

• Full 500mg per capsule
• Australian reseller with domestic dispatch
• Familiar brand for existing LVLUP customers

Cons:

• Capsule count is not published, so cost per serve cannot be verified before purchase
• High absolute price at $139.95
• Limited independent information about the formulation

Best for: Existing LVLUP customers who will contact the retailer to confirm the pack size first.

How we evaluated the best Double Wood alternatives in Australia

Eternal Elixir sells TUDCA, so it is fair to ask how a guide like this stays honest. Two rules govern it. First, we did not test any competitor product — this is a comparison built from published specifications and live retail pricing, not a laboratory exercise, and nothing below implies otherwise. Second, the criteria were fixed before the prices were collected, and the ranking is whatever those criteria produced.

• Quality and purity (30%) — stated TUDCA content per capsule, transparency of labelling, and whether certificates of analysis are published or available on request.
• Australian availability and shipping (20%) — whether the product is priced in AUD and dispatched domestically, and what shipping costs.
• Price per dose in AUD (20%) — every product normalised to cost per 500mg of TUDCA, using the seller’s stated capsule strength and count.
• Product range for stacking (15%) — whether the brand carries complementary products so one order covers a protocol.
• Customer reviews and reputation (15%) — depth and independence of the available review base.

On that scoring, Double Wood clearly wins the reputation criterion — its review base dwarfs everything else here, and it publishes certificate imagery openly, which Eternal Elixir currently does not. It loses the Australian availability and price criteria outright, because it neither prices in AUD nor ships domestically. Eternal Elixir takes price, availability and range, and that is why it finishes first for an Australian buyer specifically. In a US-focused comparison the order would look different.

What the research on TUDCA actually shows

TUDCA (tauroursodeoxycholic acid) is a bile acid the body produces in small quantities. Human research on it is real but narrower than marketing copy usually implies, and it is worth knowing what has and has not been studied.

In a randomised controlled trial published in Diabetes, researchers led by Kars and colleagues reported that four weeks of tauroursodeoxycholic acid appeared to improve liver and muscle insulin sensitivity in obese men and women — but not insulin sensitivity in adipose tissue. That mixed result is the honest summary: a measurable effect in two tissues, no effect in a third (PubMed 20522594).

TUDCA has also been through formal clinical trials in a pharmaceutical context. A randomised phase II trial published in The New England Journal of Medicine tested taurursodiol — the pharmaceutical name for TUDCA — in combination with sodium phenylbutyrate in people with amyotrophic lateral sclerosis (PubMed 32877582). That study examined a combination prescription product in a specific patient population, not a supplement in healthy adults, and it says nothing about what a TUDCA capsule will do for you. It is cited here only to show that the compound has been studied under trial conditions.

Everything else you will read about TUDCA — bile flow, digestion, cellular stress response — rests largely on preclinical and mechanistic work. Studies suggest a plausible role in each, but the human evidence base is small. Anyone taking TUDCA alongside medication or with an existing liver condition should speak to their doctor first. Our explainer on TUDCA, bile flow and the microbiome goes deeper on the mechanism.

Stacking TUDCA with the rest of a liver protocol

Most people who buy TUDCA are not buying it in isolation. It usually sits inside a broader routine, and that is one of the practical reasons a domestic brand with a deep catalogue tends to beat an overseas single-product order: one checkout, one shipment, one delivery window.

The most common pairing is with glutathione. TUDCA works on bile flow and cellular stress response, while glutathione is the body’s principal endogenous antioxidant, so the two are addressing different parts of the same picture rather than duplicating each other. Eternal Elixir’s Reduced L-Glutathione 2000mg is the usual partner at $39.99 for 90 capsules. If you want the mechanistic differences spelled out, our comparison of glutathione supplements available in Australia is the place to start.

The second common pairing is metabolic rather than hepatic. People taking TUDCA for insulin-sensitivity reasons — the outcome measured in the Diabetes trial cited above — often run it alongside Berberine HCl 500mg, which acts through the AMPK pathway rather than through bile acids. Different mechanism, overlapping goal.

If you would rather not assemble a protocol capsule by capsule, the Metabolic Wellness Stack bundles the metabolic side into a single purchase at $126.99, and the Cellular Longevity Stack at $139.99 covers the healthy-ageing angle for people whose interest in TUDCA started there. If a bundle is more than you want right now, NMN 500mg is the single-capsule entry point most people begin with, and it stacks cleanly alongside any of the best Double Wood alternatives in Australia. Whatever combination you land on, introduce one product at a time rather than three at once — if something disagrees with you, you want to know which thing it was.

And if you take prescription medication, particularly anything affecting the liver or bile, clear the whole protocol with your doctor before starting.

Frequently asked questions about Double Wood supplements in Australia

Does Double Wood ship to Australia?

Double Wood dispatches from the United States and prices its products in US dollars. Australian orders are therefore subject to currency conversion, potential card foreign-transaction fees and international shipping times. There is no Australian storefront, so there is no domestic returns address either.

Locally stocked TUDCA avoids all of that.

What is the best Double Wood alternative in Australia?

On cost per 500mg serve, Eternal Elixir TUDCA 500mg is the strongest alternative at $0.67 per serve, with 90 capsules per bottle and Australian dispatch.

Emrald Labs TUDCA is the next best at $1.66 per 500mg and suits anyone wanting a smaller 250mg capsule to start with.

How much does TUDCA cost in Australia?

Across the six products in this comparison, AUD pricing runs from $0.67 to $3.33 per 500mg serve — close to a fivefold spread for the same compound.

Bottle prices ranged from $49.90 to $169.95. Comparing bottle prices alone is misleading, because capsule strengths differ between 250mg and 500mg.

Is Double Wood TUDCA better quality than Australian brands?

Double Wood publishes certificate-of-analysis imagery on its listings and states that its TUDCA is synthetic rather than bile-derived, which is a genuine transparency advantage. Australian options in this comparison state the same 250mg or 500mg per capsule; Eternal Elixir provides batch certificates on request rather than publishing them. Quality claims should always be checked against the certificate for the batch you receive.

How many capsules of TUDCA should I take a day?

Most product labels in this category suggest one 500mg capsule daily, though some list 1,000mg. Doses used in published human research vary considerably. Follow the label on the product you buy and speak to a healthcare professional before increasing an intake, particularly alongside medication.

Where can I buy TUDCA in Australia?

TUDCA is sold by specialist online supplement retailers and direct-to-consumer brands rather than mainstream chemists. We cover the specifics in our guides on buying TUDCA in Australia and TUDCA at Chemist Warehouse.

Is TUDCA the same as NAC or milk thistle?

No. They work through different mechanisms — TUDCA is a bile acid, NAC is a precursor to glutathione, and milk thistle supplies silymarin. People often compare them because all three are marketed for liver support.

We break the differences down in our TUDCA vs NAC vs milk thistle comparison.

Why is cost per 500mg the fairest way to compare?

Because capsule strengths in this category range from 250mg to 500mg and pack sizes from 30 to 90 capsules.

A $49.90 bottle of 250mg capsules and a $59.99 bottle of 500mg capsules look close on the shelf, but the second contains three times as much TUDCA. Normalising to a single 500mg unit is the only way to see what you are actually paying for.

The verdict for Australian buyers

Double Wood is a good brand with a real reputation, and nothing here suggests otherwise. It is simply not set up for Australian buyers: US dollar pricing, US dispatch and an unpublished capsule count make it hard to know what you are paying per dose until the order lands. That is why the best Double Wood alternatives in Australia are the ones that price in the dollars you actually pay and ship from a domestic warehouse.

For an Australian buyer the Double Wood Supplements Australia question is a freight and currency question, not a formulation one. If cost per dose is what matters, Eternal Elixir TUDCA 500mg is the clear pick at $0.67 per 500mg, and the 90-capsule bottle removes two reorders a year.

If you are new to TUDCA and want a smaller capsule and a lower entry price, Emrald Labs TUDCA at $49.90 is the sensible starting point. If you are running a 1,000mg protocol and want it from an Australian warehouse, Body Essentials TUDCA 500 does that job at a premium. And if you want the Double Wood label specifically, buy it with open eyes about conversion and freight.

Whichever you choose, check the capsule strength and the capsule count before comparing prices — in this category those two numbers matter more than the figure on the front of the bottle. For the full field, our best TUDCA supplements in Australia guide covers the category in depth, and our explainer on the benefits of a TUDCA supplement answers the most common question we get about the compound.
