Please help! where can I find bile salt tablets

I've looked for bile salt tablets and I can't find them anywhere? Do I need to go to Canada or somewhere? I had my gall bladder out and I know I really need this.
Do you mean ox bile or is this a tablet that is just made of bile. I am afraid to take anything with hydorchloric acid because I realize that lack of bile flow already makes one more acidic because bile is alkaline.
Please tell me where I can get bile salt tablets.
