Common Questions about Ferrous Sulfate (FEOSOL)


When should I take ferrous sulfate?

You should take ferrous sulfate on an empty stomach (30 minutes before eating or two hours after meals) as this results in maximum iron absorption. However, because iron supplement tablets can cause occasional gastrointestinal discomfort, it may help to take them after meals. Drinking orange juice or taking a vitamin C supplement with your iron supplement can help to increase iron absorption.



How do I know if my iron is low?

Signs and symptoms of low iron include tiredness, weakness, pale skin, fast heartbeat, and shortness of breath. Your doctor can check iron levels with blood tests.



What should you not take with your iron supplement?

You should avoid taking milk, calcium, and antacids at the same time as your iron supplement (take them two hours apart). Also, avoid caffeine and high-fiber foods like grains and raw vegetables at the same time you take your iron tablets.



What food is highest in iron?

Seafood, lean meat, certain vegetables like broccoli, kale, green beans, nuts, and fortified grains are foods rich in non-heme and heme iron.



Which form of iron supplement is best?

Iron supplement tablets contain different ferrous salts such as ferrous gluconate, ferrous fumarate, and ferrous sulfate iron. The typical dosage and the percentage of elemental iron as well as how these salts are absorbed by the body and how often you need to take the iron tablets is different. Your doctor will help you choose the best iron supplement for you.
