If it's garbage, why do we need it to live?
gpt
you don't, that's one of the dumbest and most hilarious myths ever invented
humans are monogastric herbivores, we thrive on a 100% plant-based diet

Enjoy your B12 shots weekly, fruit.

B12 is synthesized and absorbed in the small intestine (not just further down in the intestine as the commonly circulated myth goes) from cobalt, which is found in ample amounts in fruits:

>«In man, physiological amounts of vitamin B12 (cyanocobalamin) are absorbed by the intrinsic factor mediated mechanism exclusively in the ileum. Human faeces contain appreciable quantities of vitamin B12 or vitamin B12-like material presumably produced by bacteria in the colon, but this is unavailable to the non-coprophagic individual. However, the human small intestine also often harbours a considerable microflora and this is even more extensive in apparently healthy southern Indian subjects. We now show that at least two groups of organisms in the small bowel, Pseudomonas and Klebsiella sp., may synthesise significant amounts of the vitamin.»

>«Human jejunal and ileal contents and ileostomy effluents were examined for the presence of free intrinsic factor. This was detected in 9 out of 10 jejunal and three out of five ileal aspirates and in one of three ileostomy effluents studied. The intrinsic factor in the ileal effluent was shown to be physiologically active. The presence of free intrinsic factor in the small intestine has considerable physiological significance in maintaining the enterophepatic circulation of vitamin B12. It would also permit the absorption of any free vitamin B12 produced by ileal bacteria.»

>«The content of the Co [cobalt] in 5 μl of apple, pear and Korean mandarin juice was identified as 150, 45 and 100 pg, respectively.»

nice try, moron

Then why do you still need the B12 shots to not become deficient? Ooooh, I see, you have to be SPECIAL and MAGICAL.

you don't
in fact, tons of vegans have zero issues with B12 despite never supplementing for decades
there are actually studies showing that the biomarkers B12 is necessary for keeping in check actually improve on a healthy vegan diet
>Vegan Diet-Based Lifestyle Program Rapidly Lowers Homocysteine Levels
>«Our results suggest that broad-based lifestyle interventions [in this case a health-conscious vegan diet] favorably impact homocysteine levels.»
and that's not even mentioning the fact that carnists become deficient in B12 all the time
this is because their microbiome, which is responsible for synthesis and absorption of sufficient amounts of it, becomes dysfunctional
again, nice try, moron
