Intrinsic factors include the genetic, physiological, and pathological characteristics of anindividual; in other words, these are traits that are “intrinsic” to a person rather than being determined by that person's environment.

Is lack of intrinsic factor hereditary? Intrinsic factor deficiency is a rare condition that is characterized by pernicious anemia and neurological abnormalities. Intrinsic factor deficiency is caused by changes ( mutations ) in the GIF gene and is inherited in an autosomal recessive manner. Treatment generally consists of vitamin B12-injections.

Is pernicious Anaemia rare? Pernicious anemia is a rare blood disorder characterized by the inability of the body toproperly utilize vitamin B12, which is essential for the development of red blood cells. There is also a juvenile form of the disease, but pernicious anemia typically does not appear before the age of 30.

What type of b12 is best absorbed? The body may absorb cyanocobalamin better, while methylcobalamin has a higher retention rate. Both can prevent B12 deficiency, but methylcobalamin should be combined with adenosylcobalamin for best results.

Can you absorb b12 without intrinsic factor? Absence of intrinsic factor, also called pernicious anemia — Intrinsic factor is a protein secreted by cells of the stomach lining. Intrinsic factor attaches to vitamin B12 and takes it to the intestines to be absorbed. An absence of intrinsic factor is the most common cause of perniciousanemia.
