人體只需要極微量的B12就可以健康生活。（若體內真的缺少了它，會導致貧血及其他健康問題。）蛋和牛奶含有維他命B12，所以素食者若兼吃這些食物，不必擔心缺乏。嚴格素食者不吃蛋不吃牛奶，也不必擔心，因為植物性食物一樣含有維他命B12，例如慈菇就是，而且多種海藻、各種豆類發酵的食品（豆豉、麵豉醬之類）酵母也有，連各種芽菜、糙米、小麥等都會有。
Strict vegetarians (vegans) who do not eat animal products and babies of mothers who are strict vegetarians are at increased risk for developing anemia and should take a supplement containing vitamin B12. Vitamin B12 is stored in the liver for a year or more, which reduces a person's risk of anemia.
