A member asked:

Is 5000mcg of b12 to much for someone who has severe fatigue? is it damaging to my body?

A doctor has provided 1 answer

Fatigue: Why you feel fatigued? Do you sleep well? Did you check your B12 level? It is a easy blood test. Please see your doctor. Vitamin B12 accumulates in your body, if you are not low on b12, then taking it do not help for fatigue.
