A member asked:
If the daily recommended daily dose of vitamin b12 is 2.4 micrograms. why do the supplements come in 1000 and 5000. isnt that way too much and dangerous?
A doctor has provided 1 answer
No, and no! Many people have vitamin B-12 deficiency, and restoration of appropriate levels often requires monthly injections of B-12. Often oral ingestion is more successful using sublingual approaches, but not always.
