Vitamin B12 Deficiency Treatment And Benefits Of Vitamin B12
Dr.Mike • onHealth & Beauty 8 years ago • 4 min read

Vitamin B12 is a member of the vitamin B complex. It contains cobalt, and so is also known as cobalamin. It is exclusively synthesised by bacteria and is found primarily in meat, eggs and dairy products. There has been considerable research into proposed plant sources of vitamin B12. Fermented soya products, seaweeds, and algae such as spirulina have all been suggested as containing significant B12.

However, the present consensus is that any B12 present in plant foods is likely to be unavailable to humans and so these foods should not be relied upon as safe sources. Many vegan foods are supplemented with B12. Vitamin B12 is necessary for the synthesis of red blood cells, the maintenance of the nervous system, and growth and development in children. Deficiency can cause anaemia. Vitamin B12 neuropathy, involving the degeneration of nerve fibres and irreversible neurological damage, can also occur.

A deficiency often manifests itself first in the development of neurological dysfunction that is almost indistinguishable from senile dementia and Alzheimer's disease. There is little question that many patients exhibiting symptoms of Alzheimer's actually suffer from a vitamin B12 deficiency.

Their symptoms are totally reversible through effective supplementation. A low level of vitamin B12 has also been associated with asthma, depression, AIDS, multiple sclerosis, tinnitus, diabetic neuropathy and low sperm counts. Clearly, it is very important to maintain adequate body stores of this crucial vitamin.

The amount of vitamin B12 actually needed by the body is very small, probably only about 2 micrograms or 2 millionth of a gram/day. Unfortunately, vitamin B12 is not absorbed very well so much larger amounts need to be supplied through the diet or supplementation. The richest dietary sources of vitamin B12 are liver, especially lamb's liver, and kidneys.

Eggs, cheese and some species of fish also supply small amounts, but vegetables and fruits are very poor sources. Several surveys have shown that most strict, long-term vegetarians are vitamin B12 deficient. Many elderly people are also deficient because their production of the intrinsic factor needed to absorb the vitamin from the small intestine decline rapidly with age.

Shellfish can be eaten raw, baked, steamed, fried, or made into chowder. Clams provide the most vitamin B-12 with 98.9µg per 100g serving, accounting for 1648% of the RDA. Mussels and oysters are also good sources of B12 providing 600 and 400 percent of the RDA respectively.


The liver of most any animal is packed with vitamin B-12, the highest on the list are: Lamb, beef, veal, moose, turkey, duck, and goose respectively. Lamb liver provides 85.7µg per 100g serving and 1428% of the RDA. Often appearing on the culinary scene as pâté, liver can also be prepared steamed or fried with onions and herbs.

Caviar (Fish Eggs)

Caviar and fish eggs are most often eaten as a garnish or spread. The eggs of whitefish contain the most vitamin B-12 with 56.4µg per 100g serving (940% RDA) while caviar contains a third of that with 20µg per 100g serving (333% RDA). Chicken eggs, by comparison, only offer 1.29µg of vitamin B-12 per 100g serving (22% RDA).
