TUDCA: What It Is, What the Research Says and Who It Suits

TUDCA (tauroursodeoxycholic acid) is a bile acid. Your body makes small amounts of it, and it is closely related to ursodeoxycholic acid (UDCA), a prescription medicine doctors use for some liver and gallbladder conditions. As a supplement, TUDCA is mostly sold for liver support.

Why people take TUDCA

Bile acids help you digest fat and help the liver move bile out to the gut. TUDCA is popular with people who want general liver and digestive support, and with gym-goers who train hard and take a lot of supplements.

What the research says

Most research on TUDCA and UDCA is in people with diagnosed liver conditions or comes from lab and animal studies. There is much less evidence in healthy people, and TUDCA has not been shown to protect the liver from harm caused by alcohol, medicines or performance-enhancing drugs. It is not a reason to take risks with your liver, and it does not replace medical care.

If you are worried about your liver, see your GP. A simple blood test can check your liver function, which tells you far more than any supplement can.

How to take it

Supplements usually provide 250 to 500 mg per serve. Follow the directions on your product's label and do not exceed the stated dose.

Who should not take it, or should check first

• People with a diagnosed liver, gallbladder or bowel condition, or a history of gallstones.
• People who take regular medication, including cholesterol medicines and any prescribed bile acid medicine.
• People who are pregnant or breastfeeding, and anyone under 18.

Some people notice loose stools or an upset stomach. Stop and see your doctor if you notice yellowing of your skin or eyes, dark urine or pain under your right ribs.
