Vitamin B12 deficiency is harmful because your body needs B12 to make red blood cells. These cells bring oxygen to organs throughout the body. If there are not enough red blood cells, you may become anaemic. Symptoms of B12 deficiency include fatigue, weakness, depression, dementia, numbness, paleness, and more. Those on a vegan diet may need to take a B12 supplement to prevent anaemia. Treatments for a vitamin B12 deficiency include vitamin B12 injections and supplements.
