Support for the hardest-working organ you ignore
Your liver processes everything you throw at it. TUDCA is the bile acid researchers reach for when they study helping it cope.
Liver support
TUDCA is a bile acid your liver already makes in small amounts — supplementing supports its daily workload.*
Bile flow & digestion
Healthy bile flow keeps fat digestion comfortable and helps move what the liver processes out.*
Cellular protection
Studied for supporting the cell's protein-folding machinery under stress — resilience at the cellular level.*
Gut-liver axis
Bile acids are signalling molecules in the gut; TUDCA supports that conversation.*
Demanding lifestyles
A favourite of people who ask a lot of their liver — training hard, travelling, or running on rich food.*
High-purity, full dose
500 mg of TUDCA per serving, disclosed on the label. No 'liver blend' padding.

The bile acid your liver already knows
Most liver products are herb assortments hoping something sticks. TUDCA takes the direct route: it is a bile acid — the liver's own working chemistry — supplied at a meaningful dose.
- A molecule your liver already knows — TUDCA is a natural human bile acid
- 500 mg per serving, the range most commonly used in the research
- No herb-blend filler — just TUDCA and cholic acid, disclosed in full
TUDCA vs the typical liver blend
When you want to support the liver, speak its language.
Common questions
What is TUDCA?
Tauroursodeoxycholic acid — a water-soluble bile acid your body produces naturally in small amounts. It has decades of research behind it for liver and bile function, and a growing literature on cellular protection.*
Who is it for?
People who ask a lot of their liver: heavy training, demanding travel and diet, or anyone who wants targeted liver support with a disclosed dose instead of an herbal lottery. If you have a gallbladder or bile-duct condition, talk to your physician first.
Why is cholic acid included?
Cholic acid is another primary bile acid. A small 55 mg inclusion rounds out the bile-acid profile alongside the 500 mg of TUDCA.
How should I take it?
Take one serving daily with food. Some people prefer it with their largest meal, when bile demand is highest.
What does it stack well with?
Sulforaphane is the natural partner — TUDCA supports bile flow while sulforaphane supports the liver's phase II detox enzymes. AstaKrill's choline also plays on the same team.*
