Listen to your body: Methyl cobalamine 500 mcg in a chewable or sublingual from should work well. If you have trouble with UTI 's or skin infections remember that bacteria also like b-12. How was it determined that you were b-12 deficient? May be you are under stress and losing b-12 or deficient in stomach acid and not making intrinsic factor. It is helpful to know cause of deficiency and treat the cause, too. ...Read more

What form/dosage of B12 should I take daily?

What form/dosage of B12 should I take daily?

Vegan?: If you eat fish, chicken or meat regularly, you probably don't need to supplement at all if you are vegan, you do. Ask your doctor to check your B12 levels to know if you are deficient. Otherwise, don't supplement. Wild fish like salmon is the healthiest source of B12 and you can eat similar fish every other day. ...Read more

WiserFocusBeneficial: Our bodies are open systems: everything coming in must go back out, else we become what does not leave.

If ↓ed; absorption ↓ed. Base dosage on your blood level & responses. ...Read more

I am looking to take liquid vitamin B12 for lack of energy. What would the recommended dosage be if I am not quite certain I am actually deficient?

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?

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. ...Read more

What is the max daily dose of vitamin B12 an adult female with very low levels can take? If her face is flushed is she taking too much?

Interesting question: Adults generally need 2.6 micrograms b12/day. To replace deficiencies, im shots bypass gut absorption problems that can contribute to deficiency in the first place. 1, 000 micrograms of intramuscular cobalamin can be given once/day for 10 days, then once/week for four weeks, followed by once/month for life. Sublingual b12, 500-1000mcg/day. The form of B12 (cobalamin) may be important; see comment. ...Read more

Gum bleeding was gone with 7- B12 inj 500 mcg daily. After the loading dose, it started again. Taking sublingual. But does not help? Cause of Gum bleding?

Infection: Probably gum disease. Easily treatable by a competent Dentist or Periodontist in its earliest stages. Treatment becomes more complex as disease advances. Please make appointment with Dentist. Unless lab tests show that you have a B12 defficiency (seen often in strict vegetarians), bleeding gums most probably due to infection. ...Read more

I want to add vitamin B12 to my daily regimen but I take Prilosec everyday for gerd. What kind of dose should I take for energy/heart health?

I want to add vitamin B12 to my daily regimen but I take Prilosec everyday for gerd. What kind of dose should I take for energy/heart health?

Vitamin B12: You can take oral vitamin B12 of 1, 000mcg daily. It's not necessarily helpful for energy or heart health, especially if you are not B12 deficient. Prilosec when used for a very long time can cause B12 deficiency. Prilosec should be taken about 30 minutes before meal, and should not be taken together with vitamin B12 as it can decrease the absorption of b12. ...Read more

Vit B12 def: Do you have pernicious anemia or vegetarian. Though recommended to be given monthly, Most patients who respond due report the waning effect of the energy boost after 2 weeks. Hence I repeat the injection in such patients after two weeks. Vitamin B12is water soluble hence not widely distributed in body tissues hence can be easily excreted ...Read more

Hi, I am 29 male - my 25 oh vit D value is 5.17 ng/ml & B12 is 195 pg/ml - kindly suggest the dosage for Becadexamin dosage or alternative to it.

Hi, I am 29 male - my 25 oh vit D value is 5.17 ng/ml & B12 is 195 pg/ml - kindly suggest the dosage for Becadexamin dosage or alternative to it.

No Becadexamin but:: Find Vitamin D3 by itself in 5000 or 10, 000 iu capsules. For levels that low take 20, 000 iu/day for 2 weeks, 10, 000 iu/day for a month and then 5000 iu/day. Monitor levels monthly- optimal levels are 50-80. You need to take 50 Becadexamin's a day to get 20, 000 iu but that would give toxic levels of iron. I advise men avoid Becadexamin as iron supplements are usually harmful for men. See comment: ...Read more

I'm 19, female, and I need the right methylcobalamin injections dosage for low B12 = 128 with depression symptoms.

Seek out cause: At your age, pernicious anemia is unusual, and would wonder about an intestinal parasite causing lack of b-12 absorption. A quest for the etiology is of value, as some autoimmune disorders may cause havoc with other organ systems. Treatment is best given via, intramuscular injections provided at least once monthly, 1, 000 mcg each. Please consult a hematologist and psychiatrist. ...Read more

I'm a lifelong vegan, was told that I should be taking vitamin B12 supplements; I can't get this from anything plant based. But what dosage, please?

1000 mcg methylcob.: A common dosage is 1000 mcg. I advise the methylcobalamin form if you can find it. B12 is usually absorbed better when taken in a sublingual form. See http://bit. Ly/1607tg3

Nutritionist told me to take vitamin B12 to help me sleep. Will it work? And is 2500mcg sublingual form too large a dosage? Thankyou

Nutritionist told me to take vitamin B12 to help me sleep. Will it work? And is 2500mcg sublingual form too large a dosage? Thankyou

It depends, no: When someone has insomnia B12 is not the first treatment that comes to mind, but B12 is needed for our bodies to make melatonin which helps regulate sleep, so if you are deficient in B12 then taking it can improve sleep. 2500 mcg is totally safe; only a small fraction of B12 is absorbed no amount of B12 is known to be toxic.

Vitamins: A good multivitamin is a good idea. It's like an insurance policy for when we don't eat right, don't sleep well, or are especially stressed. Go to a good store or get some guidance because the popular brands are typically very week and not helpful. Dose varies w/the other vitamins you mention. Need to know more. See www. Spectracell.

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. ...Read more
