Does anyone here take B12?  I was just sent a new pill which is 10,000 mcg B6 and Folic acid.  I know my body can use this but is it a safe dosage??

about 6 mcg (micrograms) is daily 100% (for 2000 calorie diet). Desk reference indicates 2.0 mcg daily (this is very small amount), but this can be exceeded ten-thousand fold , excess is excreted in urine.
I guess i average around 24 mcg daily from what I eat. sound correct?

B6 is different at about 2 mg, (up to 1 g tolerated) so 10,000 mcg is about 5 times daily requirement for B6
where 10,000 mcg= 10 mg = 0.01 grams

My daughter can't absorb B12 very well, because of the damage done to her terminal ileum, so she gets monthly shots. Even people who don't have Crohn's absorb only a tiny bit of the B12 in a vitamin (I seem to remember about 2%).
The excess B12 is excreted, so it might be safe...the real question is, "Are you able to absorb enough even from such a high dose?"
The answer depends upon what your B12 lab results look like after about a month of taking the B12, daily.

Hi I do the B-12 shots monthly. My Gi doctor says the B-12 shot is better then the pill.

if you take a b-12 supplement, you want it to be sublingual. get a liquid one you hold under your tongue.

I agree with Crazy Harry and Njmom. You want to either use a sublingual or a shot. Normal people only absorb about 2% of the B vitamins when taken orally. But with a sublingual even us with diseased bowel will absorb at least 98%. I get B12 shot every week at 1,000 mcg. and I do well on that. Good luck!
