As to seasoning cast iron, here is the most in depth source I have seen on the science. In general it is the same as the seasoning on a wok. If yours is flaking off you could try applying another coat or two. This wacky youtube guy gets into the science and seasons the crap out of his wok you might enjoy watching this!
I agree with your assessment of b12 for vegans—certainly a good idea to take! Although there are some vegan sources like nutritional yeast which has 5 mcg of B12 per tablespoon, about double the daily recommended amount for adults.
