Ferrograd C Filmtabs Ferrograd C is an iron preparation containing ferrous sulphate & vitamin C. Iron plays a vital role in production of haemoglobin, the oxygen-transporting substance in red blood cells. This maintains an adequate oxygen supply to all parts of the body. Iron is stored in the body as ferritin & is mainly obtained from the diet from meat & liver. If the body does not have enough iron in the blood, iron deficiency anaemia develops. Ferrograd C is a sustained release formulation, & therefore releases the medicine slowly over a number of hours. As a result of this slow release it reduces the gastro-intestinal problems often associated with ferrous sulphate. Directions One Ferrograd tablet should be taken once a day, or as directed by your doctor. The medicine should be taken before food on an empty stomach. However, if the tablets upset your stomach, then you may take them with or after food.
