Liver and bile support from a bile acid your body naturally makes in small amounts.
250 mg per capsule • 500 mg per serving • 30 daily servings
You slice an avocado, dress the greens with olive oil, and sit down to lunch. You can see the care you put into that meal. The next part is hidden. In your small intestine, bile salts help disperse the fat so digestive enzymes can reach it. That step helps your body make use of the foods you chose.
TUDCA is short for tauroursodeoxycholic acid, one of the bile acids found in human bile. If you want to focus specifically on liver and bile support, Double Wood puts a measured amount of that one active ingredient in each capsule.

Oil and water separate in a jar of salad dressing. Your intestine faces a similar problem. Its contents are mostly water, yet some of the nutrients you need travel with fat. Bile salts have a surface that interacts with water and another that interacts with fat. That chemistry helps disperse large fat droplets into smaller ones.
Smaller droplets expose more surface area to lipase, the enzyme that breaks down fat. Bile salts then help form tiny particles called micelles that carry the products of digestion and vitamins A, D, E, and K toward the intestinal lining. See how digestion works.
Your body recycles its bile acids. It reabsorbs about 95% of its bile acids and returns them to the liver. The same pool can help with multiple meals. Scientists call this the enterohepatic circulation. Read about bile acid recycling.
Bile is a fluid. Bile acids are ingredients in it. Water, bile salts, phospholipids, cholesterol, and bilirubin all travel in bile. Each has a different job.
The liver, gallbladder, pancreas, and small intestine each do a different part of the job.
Turn over a bottle of Double Wood TUDCA and the first question is easy to answer. What supplies the 500 mg? All 500 mg in a serving comes from TUDCA. The capsule ingredients are listed separately, so you can see exactly what you are adding to your routine.
That clarity matters if you already take digestive enzymes, taurine, or an herbal liver formula. Each has a different composition. The Supplement Facts make it easy to compare.
The front of the bottle lists 500 mg per serving. The serving is two capsules, so each contains 250 mg. A bottle of 60 supplies 30 labeled servings.
Historically, bear bile was a source of TUDCA. Double Wood states that its active ingredient is made synthetically. The capsule shell contains gelatin, which matters if you follow a vegetarian or vegan diet.
The current label lists gelatin, rice flour, vegetable stearate, and silica as other ingredients. Double Wood identifies this formula as gluten-free, soy-free, and non-GMO.
Think of the olive oil on your salad. In your small intestine, bile salts help disperse that oil into tiny droplets. This gives lipase, a digestive enzyme made by your pancreas, more surface to work on as it breaks down the fat for absorption. TUDCA belongs to the bile acid family. That’s why its label lists milligrams, while a lipase label typically lists units of enzyme activity.
At $27.95 for 30 servings, the cost is approximately $1.77 per day. The labeled serving stays the same regardless of the size of your meal.
Bile acids differ in how readily they interact with fats and water. TUDCA sits toward the more water-friendly end of that range. Researchers have followed this property from studies of human bile to experiments on how cells handle stress.

The label directs people who are pregnant, nursing, or under 18 to avoid use. If you have a liver or gallbladder condition or take prescription medicines, check with your clinician before adding TUDCA. Stop use if you develop an adverse reaction.
