Vegetarian and vegan diets have been around for thousands of years in parts of Asia, well before B12 supplements.
Vegetarianism yes… veganism I don’t think that’s really plausible.
I think this may come down to different cultures classifying what they consider to be meat.
For example if you go to Korea, it’s really really simple to be a vegetarian and almost impossible to be a vegan. Most of your basic cooking spices are going to include things like dried krill powder. And if you asked the cook or waiter if there are meat or animal byproducts, they will tell you “no meat”.
