What is TUDCA?

Tauroursodeoxycholic acid, or TUDCA for short, is a kind of bile acid made naturally in your body's liver but only in small amounts. It is also found in much larger quantities in certain animals, particularly bears.

TUDCA is a version of another bile acid called ursodeoxycholic acid (UDCA), however additionally linked to a compound called taurine. TUDCA is additionally called Ursodoxicoltaurine, sometimes known as taurursodiol.

TUDCA and UDCA play important roles in our bodies. They are involved in the production and release of bile, a substance our bodies use to break down fats. UDCA has been used in medicine for a long time to provide health in certain liver diseases and to help dissolve gallstones.

UDCA was first approved by the U.S. Food and Drug Administration (FDA) in 1987 for the dissolution of gallstones and for primary biliary cirrhosis in 1996.

In 2022, the FDA approved a medication that combines TUDCA with another substance, sodium phenylbutyrate. This medication, called Relyvrio, is used to treat a condition called Amyotrophic Lateral Sclerosis (ALS).

Researchers are also looking into whether TUDCA could be used to treat other conditions that affect the brain and nervous system, such as Alzheimer’s disease and Parkinson’s disease.

Health benefits of TUDCA

TUDCA has become popular recently as a supplement for bile acid health and liver support. Nowadays, these supplements are primarily created in a lab rather than sourced directly from animals. It is more water-soluble and less toxic than UDCA, due to conjugation with taurine. This potentially also allows for the body to absorb and use it more easily.

TUDCA is known for its role in promoting liver health, but it has other potential benefits. It has been associated with various positive health effects, which we will discuss below.

Fostering liver health

Studies have shown that TUDCA may help improve liver health. For instance, it has been found to lower the levels of certain enzymes in the blood that are often elevated in people with liver disease. This was observed in patients with liver cirrhosis who were treated with TUDCA for six months. However, it is important to note that TUDCA did not decrease the levels of markers associated with liver fibrosis in these patients.

In another study involving patients with primary biliary cholangitis (PBC), TUDCA supplementation for six months reduced serum Alkaline Phosphatase (ALP) levels compared to baseline. ALP is a type of enzyme that is often elevated in liver disease.


TUDCA, similar to UDCA, is beneficial in gallstone dissolution due to its hydrophilic and less toxic nature. It is used for oral litholysis (dissolution) of small cholesterol gallstones in patients with a functioning gallbladder.

Administering TUDCA at bedtime is recommended as it maintains the hepatic bile acid secretion rate overnight, reducing the secretion of supersaturated bile and increasing the dissolution rate.

However, less than 10% of patients with cholesterol-enriched gallstones are amenable to oral dissolution therapy with UDCA or TUDCA.


Cholesterol is an essential substance in the body, but when its levels become too high, it can lead to health issues such as gallstones, and increase the risk of cardiovascular complications.

Oral supplementation of TUDCA for two weeks has been shown to reduce serum total cholesterol, triglyceride, and LDL cholesterol levels in patients with gallstones. This finding is significant because high levels of these substances can contribute to the formation of gallstones.


Cholestasis is a condition characterized by the slowing or stoppage of bile flow from the liver. When the flow of bile is disrupted, it can lead to an accumulation of bile in the liver, which may cause liver damage.

TUDCA has been found to be beneficial in addressing this condition. Experiments conducted on rat models of the liver revealed that TUDCA may increase bile flow. By potentially enhancing the flow of bile, TUDCA may help to reduce the accumulation of bile in the liver, thereby mitigating the risk of liver damage.

Blood glucose

Researchers found that when the pancreatic islets of the mice were treated with TUDCA, these cells released more insulin in a glucose-dependent manner compared to untreated cells. This suggests that TUDCA may improve insulin secretion, resulting in better control of blood glucose levels. However, more research is needed to confirm this effect in living organisms.

In an experiment involving old mice, TUDCA injections of 300mg/kg for 20 consecutive days improved glucose tolerance, increased insulin sensitivity, and reduced fed glycemia.

TUDCA vs. other liver health supplements

Other supplements recognized for their potential benefits in promoting liver health include milk thistle and vitamins such as E, D, and B-complex.

Milk thistle is known for its active ingredient called silymarin. It is often used for its potential liver-protective properties and is believed to support liver cell regeneration and reduce inflammation. While it may offer broad-spectrum liver support, TUDCA's potential action on bile salts and cholesterol management provides a more targeted approach to specific liver issues, particularly those involving bile ducts and gallbladder function.

Vitamin E is known for its antioxidant properties, which may help protect the liver from oxidative damage. In addition, vitamin D may help to reduce inflammation and supports our immune system. Also, B vitamins like B9 (folic acid) and B12 (cobalamin) are essential for metabolic processes in the liver. While TUDCA may offer targeted benefits for certain liver conditions like cholestasis, these vitamins provide more general support for liver health and function.

TUDCA use and side effects

According to TUDCA clinical trial safety data, it is well-tolerated up to 2g/day with minimal gastrointestinal side effects. Some mild effects that have been reported include diarrhea, abdominal pain, nausea and vomiting, and less frequently, rashes and itching.

TUDCA has been reported to interact with several enzymes and efflux transporters in the body. Therefore, people taking this supplement may face increased risk of drug interactions if the individual is on any medication or using other supplements.

Pregnant or nursing women should not use TUDCA supplements, as there is a lack of research on TUDCA use in these populations.

Best TUDCA supplement: conclusion

TUDCA supplements are a promising option for those seeking liver health support, with additional potential benefits extending beyond liver care. However, as with any supplement, it is important to consult with a healthcare professional before starting any new regimen.

We recommend prioritizing quality and safety when choosing your TUDCA supplement.
