Vitamin B12 and Vegan Diets: Where to Find Reliable Advice

If you eat a vegan diet, plan your vitamin B12 sources rather than assuming that every plant-based food or general supplement contains it.

Check fortified foods and labels

The NHS recommends considering fortified foods or supplements for nutrients that can be harder to obtain from a vegan diet, including vitamin B12. Read the nutrition information to see which nutrients a particular product provides.

Choose for your actual needs

Compare the amount of B12 per serving and the directions. A product name or a general wellness claim does not establish that it is appropriate for preventing or treating a deficiency.

Get individual advice when needed

If you suspect a deficiency or already have a diagnosis, speak with a healthcare professional about assessment and treatment. Do not replace prescribed treatment with a general food supplement.
