What is Vitamin B12 Deficiency?

B12 (also known as cobalamin) is a vitamin which plays a part

in the integrity of every cell in the body, therefore it is essential

to all systems within the body. It’s key roles are in the

production of red blood cells which carry oxygen around the

body, healthy functioning of the brain and nervous system, and

the construction of DNA. Therefore any part of the body can

suffer the effects of deficiency, from your DNA through to your

mental well being.

The only natural source of vitamin B12 is from foods of animal

origin, such as meat, dairy, fish, eggs and poultry. Because of

this it is important for vegans and vegetarians to ensure that

they supplement their diets with vitamin B12.

Although B12 is a water soluble vitamin, a healthy person can

store up to 5 years worth in the liver, kidneys and other

organs. However, neither overdose nor toxicity are a concern

as the body will only store what it can use, excreting the

excess via the urine.
