Curated, not stocked.
TUDCA earns its place on our shelves because the underlying bile acid science is substantive, not speculative. It is one of the more clinically discussed compounds in liver support, with a plausible and reasonably well-characterised mechanism. Double Wood Supplements is a brand known for straightforward single-ingredient formulations. We recommend it for specific, informed use cases — not as a general wellness add-on.
About this product
TUDCA
TUDCA (tauroursodeoxycholic acid) is a bile acid that occurs naturally in the body in small amounts. Double Wood Supplements' TUDCA delivers it in concentrated capsule form, primarily studied for its role in supporting liver health and bile flow.
In the liver, TUDCA is thought to protect cells from bile acid-induced stress — a mechanism relevant to conditions of impaired bile clearance. It may also support the unfolded protein response, a cellular process that helps manage stress in the endoplasmic reticulum. This gives it a broader profile than a typical "liver tonic", and it is studied across hepatic health, eye health, and neuroprotection, though the liver evidence is the most developed.
Who might consider it: people with a history of elevated liver enzymes, those using medications with a known hepatic burden (always discuss with your doctor first), or individuals supporting recovery after periods of significant dietary stress. It is also used by some during courses of oral supplements that place additional load on the liver.
TUDCA is not an everyday baseline supplement for the general healthy population — it suits a specific clinical or contextual need. As with any targeted bile acid supplement, it is worth reviewing with a clinician if you have an existing liver or gallbladder condition. Follow the dosage guidance on the packaging and check for interactions if you take other medications.

Common questions
Frequently asked
Who is TUDCA most suited to?
It is most relevant for people with a specific reason to support liver health — for example, those with a history of elevated liver enzymes confirmed on a blood panel, or individuals taking supplements or medications that carry a hepatic load. It is not a supplement most healthy people need without a clinical reason.
Is it safe to take alongside other liver supplements or medications?
TUDCA is a bile acid and may interact with medications that affect bile flow or liver metabolism. If you take any prescribed medication, particularly immunosuppressants or drugs with known hepatic effects, check with your GP or pharmacist before starting. Do not self-prescribe if you have an active liver or gallbladder condition.
How long before I notice any effect?
TUDCA does not produce a perceptible short-term effect in most people — its benefits are biochemical and longer-term. If you are monitoring liver enzymes, blood tests at 8–12 weeks would give a more meaningful picture than subjective feel.
Is TUDCA the same as UDCA (ursodeoxycholic acid)?
They are closely related but not identical. TUDCA is the taurine-conjugated form of UDCA and is considered to have good bioavailability. UDCA is a prescription medicine in the UK for certain bile duct conditions; TUDCA as a supplement operates in a different regulatory category. If you have been prescribed UDCA, do not substitute without speaking to your doctor.
Can I take this if I have gallstones or gallbladder disease?
You should consult a doctor before taking any bile acid supplement if you have a known gallbladder condition. While bile acids like TUDCA have been studied in some cholestatic conditions, supplementing without medical oversight in the context of gallstones or gallbladder disease is not advisable.
