Everyone should be conscious of B12 and be supplementing. It's dirt cheap, and crucial to proper brain function. Last time I checked something like 40% of Americans are deficient or borderline deficient but less than 3% are vegan. Humans don't get B12 from dirty water and trace amounts of dirt on vegetables like we used to thousands of years ago and a lot of people aren't getting enough from the meat they are eating. B12 from meat is usually coming by proxy through the animal because farmers typically supplement the animals with it too. B12 is an issue for everyone.
