What are iron supplements and iron tablets?

Iron supplements, or iron tablets as they are also called, are dietary supplements that come in capsules, tablets, liquids, or other forms containing iron in various forms, usually ferrous sulfate, ferrous gluconate, or ferrous fumarate. Iron supplements can be beneficial and necessary if a person is suffering from iron deficiency.

Iron deficiency occurs when the body lacks enough iron to produce an adequate number of red blood cells. The need for iron supplements can also arise during pregnancy, breastfeeding, or in the presence of chronic diseases.

  2. Pregnancy and breastfeeding: During pregnancy and breastfeeding, the need for iron increases as iron is used to support fetal growth and to compensate for blood loss during childbirth. Many pregnant women are recommended to take iron tablets during pregnancy.
  3. Menstruation-related iron deficiency: Many women lose iron during menstruation, which can lead to iron deficiency over time. For women with heavy menstrual periods or other menstruation-related issues, iron supplements may be necessary.

  5. Vegetarian or vegan diet: People following a strict vegetarian or vegan diet may have a harder time getting enough iron from their diet since it lacks heme iron from animal sources. In such cases, iron supplements may be necessary if the diet does not compensate for this.
  6. Gastrointestinal problems: Some gastrointestinal problems, such as celiac disease or inflammatory bowel disease, can interfere with iron absorption. People with these conditions may need to take iron supplements to maintain adequate iron levels.
