I think there are several of us who use Dr. G's videos and essays as our Go-To source for accurate info.
And there are a few of us who have read at least one of his books. How Not To Die is considered the roadmap for following the WFPB diet.
In this case, his essays and videos on B12 are easy to find and read. They are both detailed and well referenced.
I would never characterize his advice as unique or different. There is a whole gaggle of doctors with diet books that have similar advice. They do have some small differences but for the most part their advice is the same.
I don't think there are any WFPB advocates who don't think B-12 is required. I think they all agree on the recommended dosages, too.
It is very reassuring to me so many authors and doctors all pretty much agree on the major things. Campbell, Fuhrman, Barnard, McDougal, Esselstien, Davis, Robbins, and Ornish, to name a few.
