Liver & bile support
Healthy bile flow. Easier digestion. Daily liver support.
TUDCA is a bile acid your liver already makes in small amounts. Ours gives you a full 500mg in one vegetarian capsule a day, with human clinical research behind it.
What one capsule a day does
Richer meals sit easier, with your liver backed every day
Your liver makes bile, which helps you digest fats and absorb vitamins A, D, E and K. TUDCA is one of the bile acids in it, and it's backed by a placebo-controlled human trial on liver and muscle metabolism.
How TUDCA works
Bile flowing. Liver supported.

Liver and metabolic support
In a 2010 placebo-controlled trial, 4 weeks of TUDCA raised insulin sensitivity in the liver and muscle by about 30%. On placebo, it didn't change. People who take it daily say richer meals sit easier, too.

Healthy bile flow
Bile breaks down the fats you eat and helps you absorb vitamins A, D, E and K. TUDCA supports healthy bile acid production and flow.
Fat digestion and fat-soluble vitamins
Liver cell protection
TUDCA eases cellular stress in the liver. Research published in Science showed how it protects liver cells.

Why a bile acid
Made by your liver. Topped up by one capsule.
Bile is how your body handles the fats you eat. TUDCA is one of the bile acids in it, and your body makes it in small amounts. One capsule adds a full 500mg.
Liver makes bile
Gallbladder stores it
Gut gets it with fat
The rest of the capsule is simple: a little rice flour and a cellulose shell. There's no proprietary blend, so you always know exactly how much TUDCA you're getting.
TUDCA has been tested in a placebo-controlled human trial, and lab research published in Science showed how it works in cells. Here is the clearest result, then three more.
Researchers describe TUDCA as a chemical chaperone that eases cellular stress and protects cells, from the liver and metabolic tissue to nerve and eye cells.
Take 1 capsule daily on an empty stomach, or as directed by your physician. That's the full 500mg serve.
Make it part of your day. No taste and nothing to measure, so it's an easy habit to keep.
Stay consistent for at least four weeks. Support builds with daily use. At 1 capsule a day, one bottle lasts 90 days.

Good to know. For adults only. Not for use if pregnant or breastfeeding, or if the seal is broken or missing. Check with your doctor first if you have a medical condition or take prescription medicine, including prescription ursodeoxycholic acid (UDCA), or if you have gallstones, a bile duct problem or a diagnosed liver or gallbladder condition. Taking antacids? Ask your pharmacist about spacing them from TUDCA. Store in a cool, dry place.

TUDCA supports healthy bile acid production and flow, which is essential for liver function and fat digestion. It also has cellular protective properties that help protect liver cells from stress and support overall liver health and detoxification.
Can TUDCA help with digestion?
Yes. By supporting healthy bile flow, TUDCA aids the digestion and absorption of fats and fat-soluble vitamins (A, D, E and K). Many users report better digestion, especially with higher-fat meals.
How much TUDCA is in a bottle, and how long does it last?
Each bottle holds 90 vegetarian capsules with 500mg of TUDCA in every capsule, 45g in total. At 1 capsule a day, 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. Many TUDCA products sold in Australia use 250mg capsules in 60-count bottles (15g per bottle), so compare the total TUDCA per bottle as well as the price.
How do I take it?
Take 1 capsule a day on an empty stomach, or as directed by your physician. Consistent daily use gives the best support. Talk to your doctor before taking more than one a day.
Is TUDCA safe for long-term use?
TUDCA has been used clinically for liver support and has an excellent safety profile when taken as directed. It's a natural bile acid derivative that works with your body's existing systems. As always, talk to your healthcare provider for advice that fits you.
Is TUDCA legal in Australia? Do I need a prescription?
Yes, it's legal, and no prescription is needed. TUDCA is sold openly in Australia as a supplement. Don't confuse it with ursodeoxycholic acid (UDCA), its parent bile acid, which doctors prescribe as a medicine.
Is TUDCA the same as milk thistle or NAC?
No. TUDCA is a bile acid. Milk thistle is a plant extract whose main active fraction is silymarin, and NAC is a form of the amino acid cysteine. All three are sold for liver support, but they work in different ways, so one is not a substitute for another.
Why can't I find TUDCA at Chemist Warehouse?
When we searched Chemist Warehouse online on 25 September 2026, it had no TUDCA products. Pharmacy liver ranges are built around herbal formulas such as milk thistle. Australians buy TUDCA from sports nutrition stores, marketplaces or direct from brands like us.
Who should not take TUDCA?
It's for adults only. Don't use it if you are pregnant or breastfeeding. If you have gallstones, a blocked bile duct or a diagnosed liver or gallbladder condition, or you already take prescription UDCA, speak to your doctor before starting. Ask your pharmacist about spacing it from antacids and about any prescription medicine you take.
Can I take it with glutathione or berberine?
Many people do, because each works on a different part of metabolism. Start them about a fortnight apart so you can tell how each one suits you. If you want all three, the Metabolic Wellness Stack already includes TUDCA, berberine and glutathione, so buy it instead of a separate TUDCA bottle.
How fast is shipping, and what does it cost?
We dispatch fast from within Australia. Metro areas usually receive orders in 3–5 business days, regional areas in 5–7. Shipping is free on orders over $100. Orders under $100 ship for $10 standard, and express is $13.
What if it isn't for me?
You're covered by our 30-day money-back guarantee. Contact us within 30 days of purchase to start a return, with the product in its original packaging. Return postage within Australia is yours to cover unless the product is faulty.
Can I pay with Afterpay?
Yes. Pay in 4 interest-free instalments with Afterpay. Cards and Apple Pay work too.
