Why TUDCA
Support for the organ that handles your fats.
Your liver makes bile, which helps your body digest fats. TUDCA is a bile acid your body already makes in small amounts. One capsule adds a full 500mg to the pool.
Healthy bile flow
TUDCA supports healthy bile acid production and flow. That helps you digest fats and absorb vitamins A, D, E and K. Many users report better digestion, especially with richer meals.
Liver health and function
Supports liver function, natural detoxification and overall liver health.
Liver cell protection
TUDCA has cellular protective properties. It helps reduce cellular stress in the liver and protect liver cells.
Metabolic and mitochondrial support
Supports mitochondrial health, healthy cellular function and overall metabolic health.
What to expect
Your first 90 days on TUDCA.
At 1 capsule a day, one bottle covers all 90 days. Here's what daily use typically looks like.
- Week 1–2
An easy daily habit
One capsule a day. No taste, no after-burps. Richer meals start to sit easier as your bile flow gets daily support.
- Week 3–8
Steady support builds
Consistent daily use supports healthy bile flow, fat digestion and liver function. Expect quiet, steady support rather than a jolt.
- Month 3
Bottle one done
The point many of our reviewers get their liver markers rechecked with their GP.
- Month 4+
Keep it going
Consistent daily use gives your liver the best support. At 1 capsule a day, that’s one bottle every 90 days, or four orders a year.
What's inside
One active ingredient. Nothing you don't need.
Each vegetarian capsule holds 500mg of TUDCA. The only other ingredient is rice flour, so the capsule carries the full daily serve and little else.

Backed by research
Studied in clinical trials and published in Science.
From a randomised clinical trial to the lab work that explained how it acts on cells.
Higher insulin sensitivity in the liver and muscle
Liver
TUDCA≈ +30%
PlaceboNo change
Muscle
TUDCA≈ +30%
PlaceboNo change
In a double-blind trial, adults with obesity took TUDCA or a placebo for 4 weeks. Insulin sensitivity in the liver and muscle rose by about 30% on TUDCA and didn’t change on placebo.

Less cellular stress in the liver
TUDCA reduced endoplasmic-reticulum stress in the liver and restored insulin sensitivity. This study established the cellular mechanism behind its metabolic effects.

A chemical chaperone for your cells
Researchers describe how TUDCA reduces cellular stress and protects cells. The evidence spans liver and metabolic tissue, and reaches as far as nerve and eye cells.

How does TUDCA support liver health?
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, 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. 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?
Follow the label: 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 the label says.
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.
