Side Effects
The human
body stores several years' worth of vitamin B12, so nutritional deficiency
of this vitamin is extremely rare. However, deficiency can result from
being unable to use vitamin B12. Inability to absorb vitamin B12 from the
intestinal tract can be caused by a disease known as pernicious anemia. Additionally,
strict vegetarians or vegans who are not taking in proper amounts of B12 by
way of supplements are also prone to a deficiency state. Low levels
of B12 can cause anemia as well as numbness or tingling in the extremities
and other neurologic symptoms such as weakness and loss of balance.

Recommendations
Recommended
dietary 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.
Because
vitamin B12 comes primarily from animal products, people who follow a strict
vegetarian diet and do not consume 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).
Many cells in our body need vitamin
B12, including nerve cells and blood cells. Inadequate vitamin B12 gradually
affects sensory and motor nerves, causing neurological problems to develop
over time. It is important to know that the neurological effects of vitamin
B12 deficiency may be seen before anemia is diagnosed.
The FDA's
reference daily intakes
(RDI) for Vitamin B12 is 6 micrograms (mcg).
