► Vitamin B12 - What is it
Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays the main role in the metabolism of every cell in the human body. Vitamin B12 is a cofactor in DNA synthesis and in both fatty acid and amino acid metabolism.

► Vitamin B12 for Good Health
Vitamin B12 is a nutrient that helps keep the body's nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent a type of anemia called megaloblastic anemia that makes people tired and weak.

► Consuming Vitamin B12 from The Food
Vitamin B12 is not naturally-occurring in vegetable dietary sources. Thus vegans and vegetarians have to take a supplement or eat fortified foods to compensate for the absence of vitamin B12 in their diet. People consuming animal products including meat, milk, eggs, and fish are obtaining enough vitamin B12 from the food they eat.

Staple foods, especially those that form part of a vegan diet, are often fortified by having the vitamin added to them.

► Vitamin B12 - Dietary recommendations
The U.S. Institute of Medicine (IOM) updated Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDA) for vitamin B12 in 1998.

The current EAR for vitamin B12 for women and men ages 14 and up is 2.0 μg/day; the RDA is 2.4 μg/day.

► Vitamin B12 - Deficiency
Every vegan, who is not consuming adequate B12 from fortified foods, has to take supplements. Foods for which B12-fortified versions are widely available to include breakfast cereals, soy products, energy bars, and nutritional yeast.

► Vitamin B12 - Who Should Take The Supplements
Because 10 to 30 percent of older people may be unable to effectively absorb vitamin B12 naturally occurring in foods, it is advisable for those older than 50 years to meet their RDA mainly by consuming foods fortified with vitamin B12 or a supplement containing vitamin B12.

► Vitamin B12 Supplements
Vitamin B12 supplements are available in the single agent or multivitamin tablets while pharmaceutical preparations may be given by intramuscular injection.

Today Vitamin B12 is included in multivitamin pills, and in some countries, grain-based foods such as bread and pasta are fortified with B12. In the U.S. non-prescription products can be purchased providing up to 5,000 µg per serving, and it is a common ingredient in energy drinks and energy shots, usually at many times the recommended dietary allowance of B12.
