Vitamin B12 Deficiency Directory

Vitamin B12 deficiency is dangerous 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 anemic. Symptoms include fatigue, weakness, depression, dementia, numbness, paleness, and more. Those on a vegan diet may need to take a B12 supplement to prevent anemia. Treatments for a vitamin B12 deficiency include vitamin B12 shots and supplements.
