Tauroursodeoxycholic acid (TUDCA) is a type of bile acid that has been found to support cellular health and promote optimal digestive system function.
Discover five impressive TUDCA benefits and learn how to use this health-promoting bile acid to enhance health and overall well-being.
What is TUDCA?
TUDCA is a water-soluble bile acid that plays a vital role in supporting liver and digestive health and has been linked to various benefits for cellular function and neurological integrity.
The body produces small amounts of TUDCA naturally through a microbial process where gut bacteria convert the bile acid chenodeoxycholic acid (CDCA) into ursodeoxycholic acid (UDCA), which is then conjugated with taurine to form TUDCA.
Along with other bile salts, TUDCA is stored in the gallbladder as part of the body’s bile acid pool, which is secreted into the small intestine to aid in fat digestion and nutrient absorption.
TUDCA has been used for centuries in traditional Chinese medicine to promote liver function, maintain healthy bile flow, and support the health and function of liver cells.
Traditionally derived from bear bile, which is exceptionally high in TUDCA, modern dietary supplements are synthesized in laboratories.

TUDCA benefits and how it works
Because of TUDCA’s unique chemical structure, it has a high affinity for interacting with liver cells and bile components, which explains its powerful benefits for liver function and digestive health.
Here are five potential health benefits of TUDCA.
1. Supports healthy bile flow
TUDCA is highly water-soluble and helps improve bile acid solubility, which plays a crucial role in maintaining optimal bile flow and gallbladder health.
Evidence published in Cells highlights TUDCA’s ability to enhance the solubility of the bile salt pool, a key factor linked to improved bile flow and a range of digestive health benefits.1
By keeping bile thin and soluble, bile acids can freely flow into the small intestine, where they’re needed for digestive functions and the absorption of dietary fats and fat-soluble vitamins.
This improved bile flow helps prevent bile sludge and stagnation, reducing the risk of gallbladder issues and liver stress.
2. Enhances nutrient absorption
TUDCA promotes efficient bile flow, which enhances the body’s ability to digest and absorb fats and fat-soluble nutrients, including vitamins A, D, E, and K.
These essential vitamins require the presence of bile and dietary fat to be absorbed through the intestinal lining and transported into the circulation.
“By supporting bile acid release, TUDCA not only aids fat digestion but also supports the body’s nutrient status,” explains Dr. Berg. “This is critical to maintaining immune function, bone health, vision, hormonal balance, and antioxidant protection.”
3. Supports digestive health
Due to its ability to promote gallbladder function and healthy bile flow, TUDCA has long been valued for its role in supporting gut health and digestive functions.
Additionally, bile acids, including TUDCA, help maintain a balanced environment in the digestive tract. This supports a diverse gut microbiome, which is critical for optimal nutrient absorption, immune function, and overall intestinal health.
Although only studied in animal models so far, TUDCA may also support intestinal barrier function, as reported by evidence published in the Journal of Animal Science and Biotechnology.2
Maintaining robust intestinal barrier function is vital for preventing the leakage of pathogens and environmental toxins into the bloodstream, thereby promoting balanced immune responses and overall digestive health.
4. Promotes liver function
TUDCA supports healthy gallbladder function, which helps the liver efficiently eliminate toxins, as bile is a primary detoxification route.
By improving bile flow, TUDCA can reduce the buildup of harmful toxins in the liver, relieving stress on liver cells and supporting optimal liver enzyme activity.
In addition, TUDCA has been found to possess antioxidant properties that help neutralize reactive oxygen species in liver cells, thereby reducing oxidative stress and protecting against cellular damage and cell death.
This protective effect helps maintain the integrity of liver cells, making TUDCA a powerful tool for liver support and cellular health.
5. Neuroprotective properties
Research published in Neural Regeneration Research suggests that TUDCA, beyond its well-known benefits for digestive and liver health, may also play a critical role in protecting neuronal function.3
This emerging evidence points to TUDCA’s potential to lower inflammation within the central nervous system, making it a promising compound for supporting brain health and cognitive function.
How and when to take TUDCA
While dosage recommendations can vary based on individual needs, a standard TUDCA regimen typically involves taking around 250 to 500 mg daily.
It’s generally advised to start with a lower dose, especially for individuals new to bile acid supplementation, and gradually increase as needed.
For optimal results, TUDCA should be taken twice daily, typically in the morning and the afternoon. This helps maintain consistent levels of TUDCA in the body throughout the day.
Depending on your health goals, TUDCA supplements can be taken with or without food.
Taking it on an empty stomach may enhance its absorption for liver and cellular benefits, while taking it with meals can support bile flow and improve fat digestion. This may be especially beneficial for individuals following a high-fat ketogenic diet.
Potential side effects of TUDCA
While TUDCA is generally considered safe when taken in appropriate dosages, it can trigger mild side effects such as bloating, diarrhea, or nausea in some sensitive individuals.
This has been confirmed by research published in eClinicalMedicine stating, “TUDCA was well-tolerated, except for a minority of patients who discontinued treatment due to side effects, primarily gastrointestinal and mild in severity.”4
However, individuals with bile duct obstruction or liver cirrhosis should avoid taking TUDCA, as this could potentially worsen these conditions or lead to adverse effects.
Pregnant or breastfeeding women, as well as those taking medications that affect bile acid metabolism, should consult a healthcare provider before incorporating TUDCA into their routine.
Key takeaways
TUDCA benefits include promoting healthy bile flow, supporting liver detoxification, and protecting liver cells from free radical damage.
In addition to its liver and digestive support, TUDCA may promote brain health by offering neuroprotective effects and reducing oxidative stress within the central nervous system.
While TUDCA is generally well tolerated, it may cause mild gastrointestinal discomfort, particularly when taken in higher doses. To ensure safety and optimal use, it’s advisable to consult a healthcare provider before adding TUDCA to your routine.
FAQ
