Vitamin B-12 is a water-soluble vitamin needed by the body for energy production, blood formation, DNA synthesis, neurological activities, and many other vital functions. Therefore, a deficiency of this vitamin might be severe. Luckily, this vitamin can easily be obtained from animal products and stored in the liver for many years. This makes deficiency uncommon for people with a healthy diet.

Unfortunately, vitamin B12 deficiency is very common among vegetarians and vegans. However, these are not the only people at risk of vitamin B12 as some normal eaters also have problems absorbing the vitamin.

If you are deficient in B12, you may take a vitamin B12 supplement. But in a severe case, your doctor may prescribe B12 Shot, an injection of a synthetic form of the vitamin. Under what condition will you need B-12 Shots, what are the benefits and side effects of the injection, and what other alternatives do you have?
