 :::::::::Personally, I wouldn't be surprised if there is B12 in shit. However, there are problems with that: 
 :::::::::*Shit is not food. 
 :::::::::*Shit is not fruit (it's an animal product, you can look it up). 
 :::::::::*Shit is full of pathogens that can fucking kill you. 
 :::::::::*We don't have reliable sources saying, ""Hey, you don't have to worry about not getting B12, just eat some shit!"" 
 :::::::::*Oh, yeah, and the reliable sources (the U.S. National Institutes of Health) do say, ""natural food sources of vitamin B12 are limited to foods that come from animals.""[28] -   "
