A 48-year-old male asked:

Taking 50,000 mcg vitamin b-12 good?

Dosage is too high: should only take up to 1000mcg daily
Dr. John Chiu
Allergy and Immunology 57 years experience
Safe but: may not do much good if you have no problem absorbing vitamin B12 . If you are a vegan, then this is a good idea since you would otherwise have no source of vitamin B12.
