Your liver makes bile. Your gallbladder stores it. But are you actually supporting the RIGHT kind?
Comment BILE and I’ll send you my free bile acid guide (esp for those without a gallbladder and / or recurring SIBO)
TUDCA and ox bile are not the same thing — and taking the wrong one means you’re leaving results on the table.
Here’s what most people don’t know: your body makes two types of bile acids.
Primary bile acids — cholic acid and chenodeoxycholic acid — are synthesized directly by your liver. Ox bile is derived from bovine sources and delivers these primary bile acids directly, mimicking what your own liver produces.
It’s essential for fat digestion, absorbing vitamins A, D, E & K, and if you’ve had your gallbladder removed, it’s non-negotiable.
TUDCA — tauroursodeoxycholic acid — is a secondary bile acid, meaning it’s not made directly by the liver but formed in the intestines through bacterial transformation of those primary bile acids.
It’s more focused on protecting cells and promoting the flow and quality of the bile your body is already making. It supports your liver, lowers oxidative stress, improves insulin sensitivity, protects mitochondria, and helps liver enzymes normalize.
Two different origins. Two different jobs.
Ox bile works downstream — replacing and replenishing what your digestive system needs to break down fat.
TUDCA works upstream — protecting the liver, improving bile quality, and supporting the gut-liver axis at a cellular level.
Most women I work with need BOTH — but for completely different reasons at different stages of their healing.
This is why I talk about bile constantly. Because almost every gut issue I see — bloating, constipation, fatty stools, hormone problems, skin issues, even immune dysfunction — has bile somewhere in the root cause.
