In brief: Nerve effects

Reported side effects to B12 vitamin include anxiety, itching, diarrhea, muscle pain, but the frequency is different with each person.
In general it is really difficult to take toxic doses of vit B12 since it is a water based vitamin and the body only absorbs and stores what it needs.
