Elemental iron

Elemental iron refers to the pure form of iron that is used in supplements to treat or prevent iron deficiency anemia. It's an essential mineral that the body needs to produce red blood cells and maintain good health. ## Mechanism of Action Elemental iron works by replenishing the body's iron stores, which is essential for the production of hemoglobin in red blood cells. Iron helps red blood cells carry oxygen from the lungs to cells throughout the body[1][8]. It combines with a protein in the blood called hemoglobin to help carry adequate oxygen to various body parts[5]. Iron also plays important roles in: - Forming myoglobin in muscle tissue, which supplies oxygen to working muscle cells[8] - Supporting muscle contraction[8] - Helping make collagen[8] - Supporting immune system function[8] - Enhancing cognition[5] ## Uses Elemental iron is primarily used to: - Treat iron deficiency anemia[1][3][5][6] - Prevent iron deficiency during pregnancy and lactation[1][5][6] - Support patients with conditions that impair iron absorption[6] - Treat breath-holding attacks in children with low iron levels[1] - Improve memory and thinking skills in children and adolescents with low iron levels[1] - Help manage heart failure symptoms (when given intravenously)[1] - Decrease symptoms of restless legs syndrome[1] ## Formulations and Dosage Elemental iron is available in various formulations: - Tablets (regular, film-coated, extended-release) - Capsules - Liquids - Drops[6] The usual dose of elemental iron to treat iron deficiency is 100 to 200 mg daily, with lower doses used for prevention[9]. For adults, the typical recommendation is approximately 200 mg of elemental iron daily[4]. One 325 mg tablet of ferrous sulfate contains about 65 mg of elemental iron[4]. ## Side Effects Common side effects of elemental iron supplements include: - Constipation - Diarrhea - Stomach cramps - Dark stools - Loss of appetite - Upset stomach[5][6] ## Precautions Elemental iron is contraindicated in: - Individuals with hemochromatosis (excessive iron accumulation) - Patients with hemosiderosis (another disorder of excess iron storage)[6] - People with iron overload syndrome[3] It should be used with caution in those with: - Heart/kidney/liver diseases - Intestinal problems like ulcers or colitis[5] Iron supplements should be taken on an empty stomach, at least 1 hour before or 2 hours after a meal. Antacids or antibiotics should not be taken within 2 hours before or after taking iron supplements[3]. Alcohol may affect iron absorption, so it's advisable to consult a doctor if there are concerns[5].
