Vegan diets need a reliable B12 source

The key question

NIH ODS explains that vitamin B12 occurs naturally in animal foods and can be added to fortified foods. Unfortified plant foods are not reliable natural sources. Calling a meal varied or organic does not solve this particular gap. The need to plan B12 is not an argument against all plant-based eating; it is a concrete nutrient requirement. Do not infer a supplement dose from a food ranking or assume every plant drink is fortified identically. [1] [2]

Look beyond a single food

A food claim needs a defined question: which food or product, what amount and preparation, for whom, and compared with what? A nutrient number does not establish a clinical benefit. Broad labels such as natural or healthy cannot replace ingredient, portion, and safety information. A workable eating pattern also depends on access, preferences, and life stage; excluding entire groups can make planning harder when there is no medical reason. [3]

Putting it into practice

Verify a consistent source and discuss an individual plan, especially during pregnancy or childhood. [1] [2]

General food guidance does not override allergy, infant-feeding, pregnancy, or prescribed dietary care. [3]
