I'm Jackie Arnett, registered dietitian, and this is vitamin B12 and the gallbladder. The gallbladder is a small organ that sits below the liver and injects bile into the small intestine whenever we eat fatty foods. The gallbladder needs a good blood supply and it also needs vitamin B12 to do its job properly. Vitamin B12 can be found in meat products like beef and turkey. It can also be found in dairy products like cheese and eggs. Vitamin B12 is important for the gallbladder because vitamin B12 is injected with the bile. So, those who have gallbladder issues or even post-gallbladder surgery find that they might have a vitamin B12 deficiency. This is due more so to an absorption issue than a diet issue where you're not eating enough meat and dairy. If you do find yourself having this problem, you should make sure that you speak to your doctor, since vitamin B-12 deficiency can be risk factor for the formation of gallbladder stones. You could talk to your doctor about supplements in vitamin B12 because that will be helpful so it'll bypass the absorption issue since you'll definitely get the vitamin B12 you need and that will help with your gallbladder too.
