How can vegans obtain vitamin B12, and is a supplement needed?
A vegan diet needs a reliable B12 source, such as fortified foods or an appropriate supplement. Unfortified vegetables are not sufficient. The plan depends on diet, age, absorption and test results; injections are not automatically required for every vegan.

Read fortification labels
Plant milks, breakfast cereals or nutritional yeast may contain B12 if fortified, but not every product does. Check the amount per serving and how often it is eaten rather than relying on a product name or a natural claim.
When assessment is needed
Fatigue, pallor, tingling or balance problems warrant review, particularly when dietary sources are limited. Deficiency can affect nerves even without obvious anaemia, although these symptoms also have other causes. Blood tests may help establish whether deficiency is present and why.
Tablets or injections?
The route and dose depend on deficiency severity, intestinal absorption and neurological symptoms. Pregnancy, breastfeeding and children’s diets need specific planning. One supplement dose is not appropriate for everyone, and a routine preventive dose should not be assumed to treat an established deficiency without follow-up.
