Our guide to why vitamin B12 is essential, why food alone isn't enough and how to choose the best vegan vitamin B12 supplement.

Switching to a plant-based diet is one of the best decisions many people make for their health, the planet and animal welfare. A well-planned vegan diet can provide almost everything your body needs, but there's one nutrient that deserves special attention: vitamin B12.
Unlike most vitamins, vitamin B12 isn't naturally found in reliable amounts in unfortified plant foods. That's why every major vegan nutrition organisation recommends that people following a vegan diet obtain vitamin B12 from fortified foods or a high quality supplement.
Vitamin B12 is an essential nutrient that helps your body:
Because your body can't produce vitamin B12 itself, it must come from your diet or a supplement.
Vitamin B12 is made by microorganisms and is naturally present in foods from animal sources because animals accumulate it through their diet or supplementation. Unfortunately, unfortified fruits, vegetables, grains, legumes and nuts are not reliable sources of active vitamin B12 so it’s important to seek out absorbable, active types of B12 from other sources.
While some plant-based foods are fortified with B12, relying on these alone can make it difficult to consistently meet your daily needs.
And for this reason, most health professionals recommend a dependable vitamin B12 supplement for anyone following a vegan diet.
You've probably heard that foods like spirulina, nutritional yeast or mushrooms contain vitamin B12.
Fortified nutritional yeast can be a useful source - but only if B12 has been added.
Fortified plant milks and breakfast cereals can contribute to your intake, but this can be limited.
Spirulina, seaweed and most algae are not considered reliable sources of active vitamin B12 for humans (although we love them as these are very nutrient-dense power-house sources of a wide range of nutrients and antioxidants!)
That's why supplementation is generally the simplest and most reliable option.
A vegan vitamin B12 supplement offers several benefits:
Maintaining healthy vitamin B12 levels helps support normal energy metabolism, nervous system function and psychological wellbeing.
It’s important to know that not all vitamin B12 supplements are equal and contain the same form of B12.
