TUDCA stands for Tauroursodeoxycholic acid, which is a water-soluble bile acid that is naturally produced in the body and also found in traditional Chinese medicine. TUDCA is allegedly known for its benefits in supporting liver health by reducing liver enzymes, inflammation, and apoptosis. It may even promote the healthy flow of bile, protecting liver cells from damage, and improving overall liver health.

In addition, TUDCA has been shown to support retinal health and has anti-inflammatory and anti-oxidative properties.

It is important to note that TUDCA is not an FDA-approved medication although many market it as a beneficial supplement. TUDCA is available for research studies and should not be purchased as a support supplement.

TUDCA Tauroursodeoxycholic Acid Product Details

TUDCA is a water-soluble bile acid that has been utilized in traditional Chinese medicine for centuries due to its potential therapeutic benefits, such as to support eye health. It is one of the eight bile acids in the body and has been found to improve insulin sensitivity and cholesterol levels in clinical studies. TUDCA is naturally produced through a microbial process, where ursodeoxycholic acid (UDCA) in the lower intestine conjugates with taurine to form TUDCA.

Potential Benefits of TUDCA

TUDCA (Tauroursodeoxycholic acid) is a bile salt that has been shown to have various potential health benefits in research studies. Many leading online stores sell TUDCA, such as Double Wood Supplements and rcd.bio.

However, it is essential to note that these findings are still preliminary and that TUDCA is not a cure for any disease or an approved dietary supplement. The article presents seven potential health benefits of TUDCA based on existing research.


TUDCA could potentially address Alzheimer’s disease in pre-clinical studies. TUDCA has been found to inhibit apoptosis in the primary culture of rat cortical neurons, suggesting that it may delay the neurodegenerative process in individuals with AD. [R] [R]

Hepatitis C

TUDCA for its effects on hepatitis C, a liver disorder that affects millions of people worldwide. A multi-center, placebo-controlled study found that TUDCA treatment produced a consistent decrease in aminotransferase serum levels (ALT) in patients with hepatitis C, indicating an improvement in their condition. [R] [R]


TUDCA has shown promising results in treating cholestasis, a disease that impairs the healthy flow of bile acids from the liver. A randomized, double-blind trial found that TUDCA treatment reduced serum alkaline phosphatase (ALP) levels, which are typically elevated in patients with cholestasis. [R] [R]

Liver Cirrhosis

TUDCA has also been studied as a potential medication for liver cirrhosis, an incurable disease that affects a significant number of adults in the US. A double-blind, placebo-controlled trial found that TUDCA therapy was safe and more effective than FDA-approved dietary supplements in treating liver cirrhosis. [R] [R]

Insulin Sensitivity

TUDCA has shown the potential to improve insulin sensitivity, which is a measure of how sensitive the body is to insulin. A trial involving 20 obese men and women with insulin resistance found that TUDCA treatment improved insulin sensitivity in the liver and muscle. [R] [R]


TUDCA has been studied as a potential treatment for high cholesterol levels, which can increase the risk of developing life-threatening conditions. However, a small study found that while TUDCA treatment reduced total cholesterol levels in cirrhosis patients, it also reduced high-density lipoprotein (HDL) cholesterol levels. [R] [R]


A double-blind, placebo-controlled study found that TUDCA improved ALSFRS-R levels in patients with amyotrophic lateral sclerosis (ALS), a rare and fatal neurological disease. [R]

In summary, TUDCA has shown potential in treating various health conditions, but more research is needed to confirm its effectiveness and safety. It is important to note that TUDCA is not a cure for any disease, and individuals should always consult with a healthcare provider before taking any dietary supplements. [R]

How It Works

Tauroursodeoxycholic Acid (TUDCA) has been gaining attention in recent years for its potential health benefits. TUDCA is a type of bile salt that is naturally produced in the liver and has a long history of use in traditional medicine. Studies have shown that TUDCA can promote liver health, support a healthy flow of bile, and even benefit eye health.

The mechanism of action of TUDCA in the human body is multifaceted. One of its primary functions is to promote liver health. TUDCA has been shown to reduce liver inflammation and oxidative stress, which can help to prevent liver damage and improve liver function. It also works by protecting liver cells from damage caused by toxins, such as alcohol and drugs.

Another benefit of TUDCA is its ability to support a healthy flow of bile. Bile is essential for digesting fats, and a healthy flow of bile is crucial for proper fat digestion. TUDCA works by stimulating the production and secretion of bile, which can help to prevent the formation of gallstones and improve digestion.

TUDCA also has potential benefits for eye health. It works by reducing oxidative stress in the eye and protecting against damage to the retina. This makes it a potential treatment option for conditions such as macular degeneration and diabetic retinopathy.


While TUDCA has a long history of usage and is generally considered safe in small amounts found in food, it should not be used to diagnose, treat, or cure any medical condition. Certain studies also suggest that researchers should not provide more than six capsules.

Test subjects with pre-existing medical conditions, especially those related to the liver. TUDCA may not be appropriate for clinical participants with severe liver damage or those who rely solely on TUDCA to support liver health.

Potential Side Effects

TUDCA has been generally considered safe for use in humans, with minimal side effects reported in clinical trials. Some of the potential side effects of TUDCA include mild digestive discomfort, such as nausea, diarrhea, and abdominal pain, which are generally temporary and resolve on their own.


In conclusion, TUDCA, or Tauroursodeoxycholic Acid, has shown promise in promoting liver support and eye health. The recommended dosage for this capsule is high quality and manufactured in the USA, with rice flour as a filler instead of bear bile. TUDCA is a naturally produced bile salt in small amounts in the body, and supplementing it with a high-quality product can provide neuroprotective benefits and support liver health.

It is important to note that this product is for reference purposes only and should not be relied on to diagnose, treat, cure, or prevent any medical condition. Its usage in traditional Chinese medicine has a long history, and its safety profile is generally considered good.

Overall, we recommend taking TUDCA under the guidance of a healthcare professional and ensuring product quality before use.

RCD. Bio also provides TUDCA in a powdered appearance. 

The powdered TUDCA has a white or off-white appearance and is extensively used in diverse research investigations. It allows for effortless measurement and the ability to tailor the dosage according to specific clinical trial demands. Conversely, liquid TUDCA is typically obtainable as a concentrated solution, offering a convenient and rapidly absorbable alternative. The decision to use either the powdered or liquid form of TUDCA depends on the particular objectives of one’s research or experiment, allowing researchers to choose the most appropriate form for their requirements.
