Swap your regular cereal for a B12 fortified one
This swap couldn’t be easier. Check your chosen brand of cereal to see whether it contains any added B12.
If your cereal doesn’t contain any extra B12, next time you’re in the supermarket pick up a box with added B12.
The milk you have with your cereal will also contain B12, with some studies even suggesting that people absorb B12 better from dairy products.
For those that don’t drink dairy products, many plant-based milk alternatives add vitamin B12 to their milk too. Soy milk is particularly high in B12, so fortified cereal with soy milk can also be a vegan-friendly breakfast swap.
