Why do we need vitamin B12?
Vitamin B12, also known as Cobalamin, is a water-soluble vitamin. However unlike other soluble water vitamins, B12 is stored in the liver and is very sensitive to ultra violet light. Vitamin B12 is used to help in the reactions to make energy as well as making red blood cells and nerves.
Sources of vitamin B12
Vitamin B12 is mainly found in animal and dairy products such as meat, fish, poultry and eggs. Vegans do not eat animal products, so have to make up on lost vitamin B12 with supplements. Fortified breakfast cereals supply vitamin B12.
What happens if I eat too much?
Taking too much vitamin B12 has no toxic effect to the human body.
What happens if I don't eat enough?
Not taking the right amounts of vitamin B12 can cause a form of anaemia, and also leads up to nerve damage and depression. It can also cause a sore tongue and weakness in the body.
How much should I have?
You should have about 1.2 µg of Vitamin B12 per day.
