RDI for vitamin B12 is 2 micrograms. So it looks like you're getting about a thousand times as much as you need.
But wait!
B12 is not readily absorbed into the body, and illness (or damage to the pancreas) may upset the production of gastric Intrinsic Factor, an enzyme that preserves B12 in the acidic environment of the stomach until it reaches the ileum, at the very end of the small intestine. High dosages allow for absorbtion in the case of a damaged ileum or Intrinsic Factor deficiency. B12 deficiencey can result in anemia, fatigue, constipation, memory loss, dementia, and even physical brain damage. Excess B12 is harmless, with no known toxicity level (between vitamin supplements and energy drink intake, I know I've had upwards of 50mg in me at once, around 1/6mg per pound of body weight) and is simply extracted from the blood by kidneys and passed from the body with urine, in which it retains its flourescent yellow color.
