Not at all: It is not uncommon to develop a defeciency in this vitamin, especially if you practice a Vegan lifestyle. It has a somewhat complicated absorption process so at times it is less than efficient and levels remain low despite food intake or supplementation. For some there is an autoimmune process calle pernicious anemia responsible for the b12 malabsorption. Injections are quickest way to correct.

B12 Deficiency: The rationale for giving a person a B12 shot is to supplement low levels. Causes of a low B12 include nutritional deficiency and poor absorption from your stomach. This does not mean you are dying.

Does B12 help boost your matabilism?

No: Vitamins help in keeping metabolism in order but do not boost it, i.e., vitamins do not increase the rate of metabolism.
A 20-year-old member asked:

Can I take green tea tablets and B12 together?

2 doctor answers5 doctors weighed in
Dr. Philip Rosenblum
Family Medicine 28 years experience
Yes: Vitamin B12 is absorbed by a complex process including a substance called intrinsic factor, which is produced by the stomach and delivered to cells in the small intestine for absorption. Although there are certain medications (acid blockers, for example) which interfere with the process by which B12 is absorbed, there is no reason to expect green tea to block any aspect of that cascade.

Provided you knew what's in that tablet. Your guess is as good as any when it comes to Chinese manufactured "natural remedies"

Can b12&mic help my energy levels?

Dr. Douglas McNeill

Do not expect much: B12 can only help energy if you are B12 deficient, a very rare condition unless you are old or have special digestive disease. I am not certain what 'mic' is. Energy comes from a good diet, movement/exercise. Make sure you are also not depressed, a real 'energy killer'.

Do B12 shots help?

Dr. William Lizarraga

Depends: What are you hoping will improve? A lot of people notice improved energy after getting a b12, that's true, but the only people who really need them are those with a deficiency of B12 that cannot be overcome with pills. Sometimes B12 deficiencies can cause nerve problems and other nervous system disease, so B12 shots can help with those.

A 37-year-old female asked:

I've been diagnosed with permicious anemia, however, the ifab test was performed after heavy B12 treatment. Could this produce a false positive?

Dr. Martin Rubenstein

No.: Pernicious anemia is caused by an abnormal antibody that attacks intrinsic factor, a chemical your body needs to absorb vitamin B12 from the gut. No if, no absorption and B12 deficiency develops. The antibody test is not influenced by B12 treatment.
