A member asked:
B12 is 132. would this be why i am chronically fatigued?
A doctor has provided 1 answer
Likely so...: Normal levels can vary per lab, but B12 level is generally considered normal if over 200. You need B12 to make red blood cells, which carry oxygen through your body. Not having enough B12 leads to anemia, which can make you feel weak and tired. See your doctor or nutritionist to see if this is diet-related or due to pernicious anemia.
