Benefits of Vitamin B-12
Vitamin B12 is a nutrient that plays an important role in many different functions of the body. The main function of Vitamin B12 is that it regulates the nervous system and keeps the brain functioning correctly. It is also an important factor in the formation of blood.

Vitamin B12 is also vital for many other systems and functions of the body. It can have a positive effect on the heart by protecting against high blood pressure and unhealthy cholesterol levels. It has been proven to help prevent many kinds of cancers including breast cancer, lung cancer, and colon cancer. It keeps hair, skin, and nails healthy by helping to renew skin cells and aiding in promoting healthy growth of hair and nails. One of the other main functions of B-12 is that it is essential to convert carbohydrates into glucose, which makes it an important element in keeping energy levels high and decreasing fatigue and lethargy.

When a person has a B-12 deficiency one of the first signs is a feeling of low energy and fatigue. It can also lead to many other issues such as poor memory, depression, weight loss combined with loss of appetite, vision problems and anemia.

When a person has absorption issues within their digestive system, it may be necessary to take a supplement. It is also recommended that vegetarians and pregnant or breastfeeding women take a B-12 supplement. Supplements are available in pill form, and for those with absorption issues it is also available as an injection or as a sub-lingual liquid. If you are able to keep foods that are rich in B-12 in your every day diet a supplement should not be necessary in most cases. Foods with high levels of B-12 that are important to your diet include meats and fish, milk and milk products, cheese and eggs.
