Vitamin B12

Vitamin B12, or cobalamin, is an essential micronutrient required in DNA synthesis and red blood cell maturation, among other metabolic functions. Its deficiency leads to a spectrum of disease. It is important to trace its absorption in order to understand how a person can become deficient.

Vitamin B12 Deficiency

Vitamin B12, also known as cobalamin, has many diverse functions in the human body. For this reason, its deficiency produces a spectrum of clinical manifestations. About 15 percent of adults above 65 years have subclinical deficiency, probably contributed to by the use of H2-receptor blockers for hyperacidity treatment, since these also reduce cobalamine levels.
