Your body needs vitamin B12 to create red blood cells, which are the tiny, disc-shaped cells that carry oxygen from your lungs to the rest of your body. When you do not have enough of this vitamin, your body produces red blood cells that are abnormally large and shaped incorrectly, preventing them from working properly.
This condition primarily affects your blood and can eventually impact your nervous system, which includes your brain and the nerves that run throughout your body. Because your body cannot make its own B12, you must get it from the food you eat or through supplements.
