What is known about vitamin B12
While the origins of vitamin B12 are relatively unknown, certain things about the nutrient are clear. Vitamin B12 is not produced by plants and can only be found in tiny organisms, like bacteria, in meat, dairy products or fermented foods, such as yogurt. And while the body readily absorbs vitamin B12, factors like medication use can deplete the body's stores of it.
Research also suggests the nutrient may be useful in treating arthritis, anemia, asthma, celiac disease, leukemia, lupus, multiple sclerosis and muscular degeneration.

Are you at risk of a vitamin B12 deficiency?
Certain conditions can affect how much vitamin B12 your body absorbs. Several groups are at a higher risk than others. You may be at risk of a vitamin B12 deficiency if you are in one of the following groups.
People with stomach problems. Research suggests irritation and inflammation of the stomach lining may hinder the body's ability to produce a nutrient called intrinsic factor, which the body needs to absorb vitamin B12.
People who use antacids. Stomach acid is needed to breakdown and unbind vitamin B12 from the dense foods (like meat) in which the nutrient is found.
Vegetarians. There are no known plant sources of vitamin B12. As a result, vegetarians should talk to their doctor or a nutritionist about proper supplementation.
People on medication. Several drugs inhibit the body's ability to absorb vitamin B12, including antibiotics, cancer medications, birth control pills, cholesterol-lowering medications and potassium supplements.
