- What Is Vitamin B12?
Why would eating liver cure anemia? That question set scientists on the road to the discovery of one of the most complex and unique vitamins. It turns out that vitamin B12 must be present for new cells to form, and it can only be made by bacteria, which is why foods from animals tend to have a lot of it. Find out the details on this page, along with some other good sources for those of you (OK, all of you) who don't much care for liver.
- Benefits of Vitamin B12
Vitamin B12 is used effectively in diseases that afflict the young and old alike. It is used to treat asthma and has shown promise against HIV. In the elderly, it can help reverse a slowdown in mental function -- and even seems to hinder Alzheimer's if the disease is caught early enough.

- Vitamin B12 Deficiency
Because the American diet is rich in animal foods, most of us get plenty of vitamin B12. In fact, the main groups of people at risk for B12 deficiency are vegans (strict vegetarians) and people whose stomachs produce less acid as they age. Some people are also born without the intrinsic factor needed to absorb B12. This page will tell you how muh B12 you need and cover the scenarios in which people don't get enough.
- Vitamin B12 Supplements
A lack of vitamin B12 usually results from the body's inability to absorb it, not from a dietary deficiency. That means that people who don't have enough must take large quantities of supplements, far more than they would actually need, so that enough of the vitamin will "stick" in the body.
