Lol read that paper. It’s literally “we have no evidence but this might be a thing?”.
the “normal” range for b12 is huge, deficiency is terribad, it comes from microbes in soil but we wash shit now. Sooooo many foods are already enriched out of caution (including animal products), b12 measurements are shit in general so data are crap, the liver stores years which further complicates things. There is good data on lower levels in plant base diets, there is good data on deficiency in poor people with shit diets and insane people with bonkers diets (frutarians etc). The scientific consensus is suppliment it because in general the body regulates itself well when given excess (unlike say b6) and deficiency is bad. That stands for basically everyone.
Likewise with other stuff, it’s all basically “idk this might be a thing so maybe pay attention?” it comes from a place of abundant caution. The same way every paper ends with “erm so yeah but maybe we need to study more?”. Also most nutrition science is junk (magical d3 anyone?) and most nutrition scientists have anti vegan biases.
