Question 1

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?

Accepted Answer

1000 micro: Equals one milligram

this dose works for most people.

See doc if any trouble.

Question 2

nutritionist told me to take vitamin b12 to help me sleep. will it work? and is 2500mcg sublingual form too large a dosage? thankyou

Accepted Answer

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. See http://bit.Ly/1hlbiaz for more on B12 deficiency.

Question 3

it has been suggested that i take vitamin b12 because the bottoms of my feet feel numb but they aren't.  i do not have diabetes.  what dosage?

Accepted Answer

B12: You should not take vitamin B12 withut getting evaluated for numbness of your feet.You should have b12, methymelonic acid levels and if you are found to be deficient in vit B12 then you need to be treated either with injectable vitb12 or nasal spray in therapeutic dases followed by maintainance doses, the numbness may due to other causes.

Question 4

can a 1ml dosage of vitamin b12 combined with 1ml vitamin b complex combined together in an injection cause nerve damage on the left lobe of a person's face.

regards 
molefe?

Accepted Answer

NO (unless...): B12 and B complex are often combined together and are extremely safe.  I've given this combo to many people and the only side effect I've seen is temporary pain at the injection site.Of course I always give in in the hip region or arm. 
The only way I could see this happening is if it was actually injected into the person's face and damaged a nerve, but it should always be given in a large muscle.

Question 5

i took vitamin b12 1000mcg on may 28th how long does it take for b12 too get out of the body fully so i can take a lower dose 250mcg.

Accepted Answer

Wrong question: Why ask this? There is no toxic dose of B12. You will absorb only a tiny fraction of these very large doses.  Why are you taking it? Most of the time 250 will be about the same as 1000. You can take the 250mcg any time.Since this is in many foods and is even produced by intestinal bacteria, a clinical deficiency occurs only in special circumstances. Vegan diet. Long term use of PPI or H2 blocker s

Question 6

if the daily recommended daily dose of vitamin b12 is 2.4 micrograms. why do the supplements come in 1000 and 5000. isnt that way too much and dangerous?

Accepted Answer

: No, and no!  Many people have vitamin B-12 deficiency, and restoration of appropriate levels often requires monthly injections of B-12.
Often oral ingestion is more successful using sublingual approaches, but not always.

Question 7

is it possible to get over dosed by taking too much vitamin b12, if you are taking recommended daily dose as per literature that comes with b12 supplement?

Accepted Answer

: I wouldn't worry about it. B 12 when taken by mouth is only transiently in your system. Any in excess of B 12 not needed/utilized by the body that day will flush out of your system in your waste. You develop problems from a lack of B 12, not supplements that assure you have it.

Question 8

is it ok to take a daily dose of vitamin b12 with fish oil gels?

Accepted Answer

Fish oil: Fish oil and B12 are compatible.

Question 9

what is the most common cause of anemia and/or vitamin b12 deficiency in older adults?

Accepted Answer

: In women of reproductive age, blood loss through menstruations is a common cause of iron deficiency anemia. B12 deficiency is usually due to poor absorption resulting from lesions in the stomach and/or ileum. Alcohol abuse can cause deficiency of both iron and B12. In adult men iron deficiency anemia warrants an investigation of GI bleeding.

Question 10

have vitamin b12 deficiency, and was told to start taking daily high dose oral supplements (injections not practical). so many options! what's best?

Accepted Answer

Try sublingual tabs: Try the sublingual tablets, then get  your levels tested in 3-6 months. Place the tablet beneath your tongue/allow it to dissolve.Can be taken with /without food.Heavy alcohol intake can decrease the effectiveness of this medication. Talk with you doctor if you are drink alcohol on a regular basis.  B12 also available in tablet / nasal forms. B12 found in meat, fish, liver cheeses/milk. Take car.
