There are numerous Vitamin B12 benefits, but Vitamin B12 is probably most well known for being the "energy-boosting" vitamin. Last year as Justin Timberlake was helping to induct Madonna into the Rock and Roll Hall of Fame, he mentioned that she took Vitamin B12 shots and had offered to give him one.

As everyone knows, Madonna is a total fitness fanatic who happens to be in the best shape of her life at age 50, so when her pal Justin told this little story about her, I don't think anyone in the audience was terribly shocked. Fortunately, you don't have to have your Vitamin B12 injected in order to reap the Vitamin B12 benefits. Eating foods that contain Vitamin B12, such as milk, meat, fish, poultry, eggs and vitamin-fortified breakfast cereals, will work just fine. So what exactly is the big deal about B12? Read on to find out.

Consuming vitamin B12 (also called cobalamin) helps red blood cells and nerve cells and assists in the formation of DNA.

The reason that B12 is known as the "energy vitamin" is that it (along with the other B vitamins) aids the human body in the conversion of carbs to glucose (sugar), which in turn provides the body with energy, so consuming it can give you an energy boost.

People who do not consume enough Vitamin B12 may be suffering from a Vitamin B12 deficiency, which may in turn cause them to suffer fatigue, (and, in more severe cases, it appears to be a factor in the development of cystic fibrosis and sickle cell anemia).

Vitamin works with other B vitamins to limit the amount of homocysteine produced in the body, which means that it may help to prevent cardiac problems, Alzheimer's disease and strokes.

Vitamin B12 improves digestion and protects you from developing certain forms of anemia. It also appears to help people to fight off depression and migraines

To achieve the maximum Vitamin B12 benefits, you should try to consume it in the foods mentioned earlier. (Of course, it is also found in all multivitamins, or if you prefer, you can purchase B12 supplements.) Another way to get extra Vitamin B12 into your diet is to take Emergen-C, which contains not only 1000 mg of Vitamin C (to boost immunity against colds), but also several B vitamins, including Vitamin B12.
