Are you getting enough vitamin B12 to stay healthy?

Vitamin B12 is essential for red blood cell production, healthy nerve tissue and brain function. Vitamin B12 deficiency leads to megaloblastic anemia. It is most often caused by malabsorption from food, pernicious anemia (an autoimmune disease that affects gastric mucosa), postsurgical malabsorption, and dietary deficiency. However, for many deficient individuals the cause is unknown.

Early diagnosis and treatment of vitamin B12 deficiency is important to avoid irreversible damage associated with neurological symptoms of vitamin B12 deficiency.

What’s included in the Vitamin B12 Test?

Vitamin B12
Vitamin B12 is a water-soluble vitamin that is required for red blood cell formation, neurological function, and DNA synthesis. Vitamin B12 is bound to protein in food and must be released from the protein by hydrochloric acid and gastric protease in the stomach. Synthetic vitamin B12 in fortified foods and supplements is already in a free form.

Many animal products contain vitamin B12, including fish, meat, poultry, eggs, milk, and milk products, but it is generally not present in plant foods. Fortified food products include breakfast cereals and nutritional yeast. Dietary supplements containing vitamin B12 are also available, usually containing the cyanocobalamin form.
