What do you crave when your B12 is low?

B12 deficiency can cause specific food cravings, particularly for meat, fish, or eggs, as your body seeks sources of the vitamin, and may also lead to sugar cravings due to its role in serotonin and energy regulation, but it can also manifest as pica (craving non-food items like ice or even bleach in severe cases). These cravings signal your body trying to correct a nutrient imbalance, but clinical testing is needed for a proper diagnosis, as emotional factors also drive cravings.

The fastest way to recover from B12 deficiency, especially severe cases, is through B12 injections (cobalamin), often starting with frequent shots (e.g., every other day for a couple of weeks) to rapidly replenish stores, particularly if neurological symptoms are present, followed by oral supplements or less frequent injections, depending on the underlying cause. While dietary changes and high-dose oral supplements help, injections bypass absorption issues for quicker correction.
