Tauroursodeoxycholic acid (TUDCA) is a bile acid that works inside cells as a chemical chaperone, assisting proper protein folding and lowering cellular stress. This action promotes healthy bile flow and liver function.
People take TUDCA to aid liver health and fat digestion. Some use it for general cellular upkeep, though that use remains investigational. The supplement is available as capsules or powder.
Clinical doses typically range from 1,000 to 1,500 milligrams per day, split into two or three doses and taken with food.
TUDCA may interact with medications that involve bile acid metabolism. As a bile acid, it could also alter how the body absorbs fat-soluble vitamins and certain drugs.
