Undigested vitamins stored in gut?

In June of 2020, I was taking B vitamins. I started to poop them out whole so I stopped taking them in August of 2020. For 2 years they come out one at a time fully formed. So far there have been about 30 vitamins. They come out once every couple of weeks or months. Today, 04/11/22 another came out perfectly in tacked. Where are they being stored in my body?

That is a good question. The capsule should have broken down anywhere in the digestive tract. Likely the vitamin capsule was not capable of being dissolved or releasing the vitamins. You may have pouches off the small or large bowel where this immortal capsule was lodged for a long time.
I've never heard of such a thing happening but if they are being stored somewhere it would be in the cecum of the colon. It's possible that they get released periodically from the cecum into the rest of the colon, then released in the stool. Another remote possibility is that you have a diverticulum in the GI tract that is storing the pills.
Sometimes they may come out without breaking down. JB
