Iron plays a vital role in production of haemoglobin, which is the oxygen-transporting substance found in red blood cells. If the diet does not contain enough iron, the body cannot make enough new red blood cells. This results in iron deficiency anaemia, with symptoms such as tiredness, palpitations, shortness of breath, dizziness and fainting.
To treat iron deficiency anaemia, iron supplements such as this one are needed. The increased iron intake allows the body to increase its production of red blood cells.
Ferrograd tablets are a ‘modified-release’ form of ferrous sulphate. They are designed to release the iron slowly over the day as the tablet passes through the gut. This may help to reduce the digestive side effects that can sometimes be a problem with iron supplements. However, if side effects are reduced compared to other iron tablets this may be because less iron is being absorbed, because Ferrograd tablets carry the iron into an area of the gut where absorption may be poor.
The absorption of iron from the gut is decreased if it is taken at the same time as coffee, tea, eggs or milk. Its absorption is enhanced if it is taken at the same time as foods or supplements containing vitamin C (ascorbic acid).
