Ox Bile Extract
Supplemental bile acids that restore fat digestion and fat-soluble vitamin absorption after gallbladder removal or bile insufficiency.
What the evidence says
Most Ox Bile studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality randomised trials published 2012–2020.
Based on 3 studies · 1 RCT
Confidence
LowBy outcome
Ox Bile has an evidence score of 6/10 — moderate evidence based on 3 indexed studies. Supplemental bile acids that restore fat digestion and fat-soluble vitamin absorption after gallbladder removal or bile insufficiency.
The commonly studied dose of Ox Bile is 100-500mg with fatty meals. Research points to an estimated optimal dose around 500mg, with a minimum effective dose near 100mg. Individual response varies — start low and adjust.
The best time to take Ox Bile is with meals. Take it with food. Ox bile extract provides conjugated bile salts (primarily glycocholic and taurocholic acid) that emulsify dietary fats for digestion and absorption.
Digestive Enzymes
Likely helpsEnzyme blend that supports digestion of proteins, fats, carbohydrates, and fiber, reducing bloating and improving nutrient absorption.
Bromelain
Likely helpsProteolytic enzyme from pineapple that aids digestion with food or provides systemic anti-inflammatory and recovery benefits on an empty stomach.

Ox Bile provides supplemental bile acids for people who have had their gallbladder removed or who have insufficient bile production. Bile is essential for digesting and absorbing dietary fats and fat-soluble vitamins. Without adequate bile, people experience fatty food intolerance, bloating, and nutrient malabsorption.
Breaks down fats into smaller droplets
Enables absorption of vitamins A, D, E, K

100-500mg with fatty meals
Loading: Start with lower dose and adjust based on fat content of meal
Take with food
| Form | Type |
|---|---|
| 💊Ox bile capsules | Recommended |
| 💊Combination digestive enzymes with bile | Alternative |
| 💊Bile salts | Alternative |
Often combined with lipase for enhanced fat digestion.
Minimum: 1 weeks
Optimal: 4 weeks
Cycling: Not required
Note: Only needed with meals containing significant fat. Dose based on meal fat content.
Based on observational studies showing bile acid metabolism effects in specific populations (cholecystectomy, MS). Limited direct human intervention data. Most evidence from disease-state populations rather than healthy individuals.
Less discomfort after fatty meals
Improved absorption of fat-soluble vitamins
Less post-meal bloating and discomfort
Primary indication; often very helpful
Tip: Reduce dose
Tip: Take with food
Ox Bile is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are loose stools, stomach upset. Use caution if any of these apply to you: Bile duct obstruction; Acute gallbladder inflammation.
Serrapeptase
Mostly mechanism / observationalSilkworm-derived enzyme that breaks down inflammatory proteins and thins mucus — used in Europe and Japan as an NSAID alternative.
