Vitamin B12 deficiencies may happen when you aren’t getting the right nutrients in your diet, when your body can’t absorb nutrients properly, and when you have various other problems of the digestive system.
Since most B12 in our diets comes from animal products, vegans are at risk for B12 deficiency. Crohn’s and celiac disease, weight loss surgery, and chronic alcoholism can all interfere with a person’s ability to absorb enough of the nutrients they need. Seniors have more problems with nutrient absorption and malnutrition as well.
Vitamin B12 is a critical nutrient that helps your body make healthy red blood cells. If you have a chronic lack of B12, your body can’t make the amount of red blood cells that it needs, which can lead to anemia.
