A member asked:

My friend self injects every day and takes 5mg folic acid everyday.she is b12 def. doc also injects ever 4 weeks. is it to much. doc don't know?

A doctor has provided 1 answer

No harm, no benefit: One mg of folic acid/day is more than sufficient. A doctor giving her injection every 4 weeks is also more than sufficient for B12. Taking more of these vitamins will not do harm but will not do any good either.
