It is certainly far more than you could possibly require. It is over
200 times the recommended daily allowance. There is no good
evidence to suggest that such a high intake is in any way
beneficial, nor is there any that it is in any way harmful. No
"official" upper safe level of consumption has been set, nor have
symptoms of B12 toxicity been reported.
