Everyone needs the addition of B12 in their diet. But if you are a vegetarian or vegan, you’re may be lacking more than your carnivorous friends. B12 is not found in plants, only in animal products and supplements.
We need B12 for the production of red blood cells (which carry oxygen), and for making DNA. Even if you eat animal products, you may have trouble with absorption if you suffer from Crohn’s disease Autoimmune diseases or gastritis take anti-acids or drink heavily.B12 deficiency can lead to anemia, severe fatigue, nerve damage, vision loss and childhood developmental delay.
Adults need 2.4 mcg/d ( 2.6 if pregnant). That does not sound like much, but the key is a good, easily absorbable source
Food sources include: Red meat, eggs, fish, chicken, dairy. Also fortified foods like grains, and oral supplements. This is a very important vitamin so don’t skimp, no matter what form you choose.
