What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Ox Bile is an other most often used for fat digestion, fat-soluble vitamin absorption, post-gallbladder support. NutriStack rates the overall evidence as moderate. A typical adult dose is 125-500 mg per fat-containing meal, commonly taken as ox bile extract (often combined with lipase). This profile indexes 14 sources.
The bottom line
Evidence rating moderate. Most-documented uses: fat digestion, fat-soluble vitamin absorption, post-gallbladder support. 14 sources indexed (1982–2025), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Bile acids emulsify dietary fats into micelles for lipase access. Essential for fat-soluble vitamin absorption (A, D, E, K). Also has antimicrobial effects in the small intestine.9,1
Dosing & protocol.
What it actually costs.
Real-world pricing across three quality tiers. Assumes Ox Bile Extract.
Weak estimate: assumes 125-500 mg with a fat-containing meal. Vendor basis: NOW/iHerb, Vitacost, Amazon marketplace, and digestive enzyme blends; meal frequency changes monthly cost. Updated 2026-05-28.
The same dose, as food.
How much you'd eat to match a supplemental dose.
Ox bile is an animal bile preparation used as a digestive aid; ordinary foods do not supply equivalent bile salts.
