What causes vitamin B12 deficiency anemia?

Can eating more foods with B12 help me get better?

Question 13

Will I need medicine for my vitamin B12 deficiency?

Question 14

Are there side effects from taking too much B12?

Accepted Answer

B12 is a water-soluble vitamin, which means your body gets rid of extra amounts through urine, so taking too much B12 is very unlikely to cause harm. Side effects from B12 treatment are rare, but some people may have mild reactions like itching or redness at injection sites. (Source: MedlinePlus)
