This is dumb. Your kidney produces every vitamin you need.
B12 is not produced by the body. It took 10 seconds of Google to figure that out.
Actually, some B12 is synthesizable by gut bacteria. However, the bulk of our B12 stores come from consuming animal products.
I believe that is done by bacteria too far in the digestive tract to be used but yes you are correct.
Definition of a vitamin is something that you must have, but the body does not produce. Vitamin C, for example. If your kidneys made it, scurvy would not exist.
Good grief......
