Ox Bile
At a glance
- Best for
- people without a gallbladder or with bile-acid insufficiency causing fat malabsorption
- Typical dose
- 100–500 mg with fatty meals
- Time to effect
- Meal-to-meal
- Main caution
- Can cause diarrhea; avoid with bile-duct obstruction
What is it
Ox bile is a dried extract of bile from cattle, supplying bile acids (conjugated cholic and deoxycholic acids) that help emulsify and absorb dietary fats and fat-soluble vitamins. It is used as a digestive aid, most rationally in people who lack their own bile flow, such as after gallbladder removal. Its supportive use rests on physiology rather than large clinical trials.
Is it worth it for you?
Worth considering if…
- You have had your gallbladder removed and get fatty stools or post-meal discomfort
- You have documented fat malabsorption from low bile output
- You react to high-fat meals with bloating after cholecystectomy
Probably skip if…
- You have normal bile production and no malabsorption
- You have any bile-duct obstruction
- You expect it to treat unrelated digestive problems

| Goal | Evidence | Effect | Best fit | Time |

fat malabsorption after gallbladder removal or bile insufficiency
Corrects deficiencyBile acids are physiologically required to emulsify fat and absorb fat-soluble vitamins, so supplementing them is rational when endogenous bile is inadequate, such as after gallbladder removal. Direct controlled trials of ox bile supplements for these symptoms are limited, and most support comes from physiology and clinical experience. Benefit is most plausible in genuine bile insufficiency rather than general digestion.
Bottom line: Physiologically sound for bile-acid insufficiency, though formal trial evidence is thin.
