B12 deficiency

Vitamin B12 is a nutrient that helps keep your body’s blood and nerve cells healthy and helps make DNA, the genetic material in all of your cells. Vitamin B12 also helps prevent megaloblastic anemia, a blood condition that makes people tired and weak.
How we absorb Vitamin B12
Most people get enough vitamin B12 from the foods they eat. But some people have trouble absorbing vitamin B12 from food. The body absorbs vitamin B12 from food in a two-step process. First, hydrochloric acid in the stomach separates vitamin B12 from the protein that it’s attached to. Second, the freed vitamin B12 then combines with a protein made by the stomach, called intrinsic factorhdcc, and the body absorbs them together.
This means Vitamin B12 in dietary supplements isn’t attached to protein and doesn’t require the first step. However, B12 in supplements does need to combine with intrinsic factor to be absorbed. People with pernicious anemia, an autoimmune disease, can’t make intrinsic factor. As a result, they have trouble absorbing vitamin B12 from foods and dietary supplements.
