Is vit b12 deficiency dangerous

Answer 1

Vitamin B12 has a very low potential for toxicity. The Institute of Medicine states that "no adverse effects have been associated with excess vitamin B12 intake from food and supplements in healthy individuals." The Institute recommends that adults over 50 years of age get most of their vitamin B12 from supplements or fortified food because of the high incidence of impaired absorption of B12 from unfortified foods in this population.

Answer 2

Shortage of B 12 causes many problems including permanent nervous tissue damage. However treatment is relatively simple and can include taking pills, a nasal spray, injections, oral liquids or a patch. Pernicious anemia is usually the result of insufficient secretion of intrinsic factor within the stomach.; this can be fatal if untreated for over 3 years.

Answer 3

Researchers in Denmark have found that higher than normal levels of this necessary vitamin may indicate a person is at risk of developing certain cancers. Their study appears in the Journal of the National Cancer Institute.

Significantly, the authors noted in their study that high plasma B12l levels are probably not related to a patient's consumption of foods or dietary supplements containing vitamin B12, as intake does not substantially increase levels in the blood. High B12 levels result from unknown causes, possibly some kind of malignant process.

Answer 4

Vitamin b12 also known as cyanocobalamin is NOT dangerous. It is very important vitamin found in meat and other animal products. Even the overdose of b12 doesnt cause any fatal illnesses ( overdose causes skin rash) because this vitamin is water soluble and can be excreted through urine.
