Question 1

is 1000mcg of b12 too much to take daily?

Accepted 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.

Question 2

is 2500 mcg of b12 too much to take at once?

Accepted Answer

No: Inefficiently absorbed and no down side to "too much".

Question 3

i take 500 mg of b12 every day. my b12 blood work level came back at 1,279. it said 214 to 914 is range for b 12. should i consider taking 500 mg every other day to bring it down to the middle range?

Accepted Answer

: The liver stores about a year's worth of vitamin B12. You may stop taking B12 for three months and retest. Please note that elevated levels of B12 may be an indication of an inflammatory process. It would be prudent to discuss it with your doctor at the next visit.
Wish you good health!

Question 4

i'm wondering how much time it will it take for vit b12 injection to show its results?

Accepted Answer

Rapid: If you are B12 deficient, the anemia will improve and reticulocyte count rise within a week. If your have a neurologic deficit, you'll notice an improvement in a week or two. If you're being given B12 as a placebo or part of a "natural healing" scheme, there's no answer as it's not benefiting you beyond the power of suggestion. Be sure you understand why and whether it's long-term.

Question 5

is 500mg of b12 to much to take? if so what's the recommended dose?  d3 1000 mg a day to much if so what's the recommended dose?

Accepted Answer

Not too much: 500 mg of B12 is fine. But beware that B12 can compete with folate (folic acid) for absorption, so take some folate (folic acid) too. Metafolin is good.
D3 1000 iu is not too much. Some people need more. Check bloodwork 25 oh d to know your level.. 50-60 is a good number and below 40 is on the low side.

Question 6

what if i will take b12 with lipotropic injections, how much weight will i lose?

Accepted Answer

No: If you experience side effects, you can discontinue the medication and the side effects will subside.

Question 7

could you tell me if i will take b12 with lipotropic injections, how much weight will i lose?

Accepted Answer

No idea: No one can predict exactly how much weight any given individual will lose on any given treatment. Many other factors affect weight. Some, such as diet and exercise, are under your control.

Question 8

is taking b12 and b6 in pill form better then taking them in desolving stripes. and how much i take of both?

Accepted Answer

Just eat right.: Unless you have an identified deficiency of either of those vitamins you do not need to take them.  Just eat a regular diet. I am not sure that one product is better than the other on a mg per mg basis.

Question 9

is it safe to take spring valley chewable b12 2500 mcg more than directed? one doesn't work enough for me, how much is too much?

Accepted Answer

Yes, no toxicity: Yes, it's safe to take more but it's very unusual to need more. Vitamin B12 is considered to be non-toxic so there is no known dose that is "too much."
However, it's not well-absorbed so taking more than 2500 mcg may not increase the amount you absorb. I'm wondering what you mean when you say one doesn't work for you- what symptoms do more relieve that one doesn't? See http://tinyurl.com/oc8up5z

Question 10

29yr male.taking monthly b12 neurobianforte shots-1000mcg.but i get tired in 20days.can i take higher dosage?how much time would it take for recovery?

Accepted Answer

Recheck B12 level: Before increasing your dose of vitamin B12 supplementation, you should have your vitmain B12 level rechecked to make sure that it has not yet normalized. If your vitamin B12 level has normalized and you're still feeling tired, then there may be other causes for your lack of energy that should be discussed with your primary care physician. http://www.nlm.nih.gov/medlineplus/ency/article/002403.htm
