Iron supplements refer to medications that are taken orally in order to increase the levels of iron in a person's body. Iron is an essential mineral that plays several important roles, including helping red blood cells carry oxygen throughout the body and supporting energy production. Some people may need to take iron supplements if they have been diagnosed with iron deficiency or anemia, which can result from poor diet, heavy menstrual periods, or other medical conditions. Iron supplements come in different forms such as tablets, capsules, and liquids, and it's important to follow the recommended dosage instructions carefully to avoid potential side effects or complications.
