I'm a vegetarian in my 70s, I don't eat eggs or drink milk (I do eat cheese and butter). I had a very severe dizzy spell - diagnosed as B12 deficiency and now have to have regular B12 injections. B12 deficiency over-65 is very serious & there is no B12 non-animal suppliment that is proven to work.
Ok but that's not relevant to what's being discussed here
Well, to me, it is. It may be mainly about B6, but it also mentions B12 rather casually, and B12 is far from being a casual vitamin! It seemed an appropriate place to add a warning about B12 deficiency - which is very serious in the elderly.
