Vitamin B12
Posted: 05-25-05 03:57am

Vitamin b12

definition
a water-soluble vitamin; part of the vitamin b complex.

Function
vitamin b12, like the other b vitamins, is important for metabolism. It helps in the formation of red blood cells and in the maintenance of the central nervous system.

Food sources
vitamin b12 is found in eggs, meat, poultry, shellfish, and milk and milk products.

Side effects
because the body stores several years' worth of vitamin b12, nutritional deficiency of vitamin b12 is extremely rare.An inability to absorb vitamin b12 from the intestinal tract can, however, occur.This can be caused by a disease known as pernicious anemia.Low levels of b-12 can cause anemia as well as numbness or tingling in the extremities or other neurologic symptoms.

Recommendations
recommended daily allowances (rdas) are defined as the levels of intake of essential nutrients that, on the basis of scientific knowledge, the food and nutrition board judges to be adequate to meet the known nutrient needs of practically all healthy persons.

The best way to get the daily requirement of essential vitamins is to eat a balanced diet that contains a variety of foods from the food guide pyramid.
Edit


since vitamin b12 comes primarily from animal products, people following a strict vegetarian diet ( i.E., not consuming eggs or dairy products) may require vitamin b12 supplements. Non-animal sources of vitamin b12 exist, but are highly variable in their b12 content, and are therefore unreliable sources.

Specific recommendations for each vitamin depend on age, gender, and other factors (such as pregnancy).The u.S. Department of agriculture has a pdf file that lists these recommendations.

Can I Buy Injectable B12 W/o Prescription?
Posted: 06-18-05 10:30am

I find it readily available in all other forms. My mom can't absorb any of the ones that go thru the stomach and the sublingual doesn't seem to do much.

I find sites that require a prescription, veterinary sites, and romanian sites for ordering injectable b12, but none of the common u.S. Vitamin sites seem to sell the injectable version.

Does anyone know of a safe, legitimate way I can purchase this without a prescription?

probably not! Allowing your hair to grow out and not coloring it will allow your hair to return to normal/natural color.

Vitamins are not miracle pill, they just provide adequate health needs for the body.

as far as I am aware, you have to go to a doctor to have this med administered. You might go to your mom's primary care doc and see if he can either give you guys samples/syringes or offer assistance in some way to make it easier on your mom to obtain these injections.

Thanks for your question.
I agree with tamadrummer's opinion.
You'd better call your mom's doctor and listen to the doctor's professional advices.

There are specfic disorders in humans that do not allow for "high" or "low" quality supplementation of b12 or other b vitamins. It cannot be fixed by spending more on a supplement. Those people have to have "doctor" prescribed and administered b vitamin injections.

Please do not go buy your mom a high dollar vitamin that she will just excrete out in her feces/urine because she cannot absorb them not from food (real high quality) or by pill.

And at this point it should be obvious that buying from someone that is not a proffesonial trained with a "real" "college" "degree" in nutrition should not be advising your purchase or administration of vitamin supplements.

If you would like to read more about how these so called good vitamins work you should read in consumer reports oct 2002 on vitamin supplements and then there are other issues about how the big money suppliers that are supposed to be better actually don't even contain 25% of the stated supplement on the label.
