Vitamin B12 (cobalamin) is found in foods sourced from animals, like meat, eggs and milk. It plays an important role in the formation and maturation of red blood cells – the key carrier of gases in the blood. Vitamin B12 also helps cells to synthesise DNA and plays a key role in the structure and functioning of the nerves. The body stores about 2.5mg (milligrams) of vitamin B12 and adults only need approximately 2mcg (micrograms) per day while 0.7 mcg is sufficient for children.
