A member asked:
Is 1000mcg of b12 too much to take daily?
A doctor has provided 1 answer
Maybe: The recommended daily allowance for a health adult is only 2.4 micrograms but depending on other health circumstances such as pernicious anemia or other reasons to have a B12 deficiency, the recommendation could go as high as 2000 micrograms. B12 is cleared by the kidney so taking too much is urinated out of your system.
