Study Notes
Iron Supplements
What are iron supplements?
- Iron supplements are dietary supplements that contain iron, an essential mineral for the production of hemoglobin, a protein in red blood cells that carries oxygen to the body's tissues.
Why are iron supplements needed?
- Iron deficiency is a common nutritional disorder that can lead to anemia, fatigue, weakness, and shortness of breath.
- Iron supplements are necessary for individuals who have:
- Iron deficiency anemia
- Chronic bleeding (e.g., menstruating women, individuals with ulcers)
- Increased iron requirements (e.g., pregnant women, athletes)
- Malabsorption of iron from food sources (e.g., individuals with celiac disease)
Types of iron supplements
- Ferrous sulfate: most commonly used form, well-absorbed, and inexpensive
- Ferrous gluconate: more expensive, but better tolerated and less likely to cause gastrointestinal side effects
- Ferrous fumarate: less commonly used, but may be better tolerated than ferrous sulfate
- Iron amino acid chelate: a more expensive, highly bioavailable form
Benefits of iron supplements
- Treats iron deficiency anemia: increases red blood cell production, reduces fatigue, and improves energy levels
- Improves exercise performance: enhances endurance and reduces fatigue in athletes
- Supports pregnancy: essential for fetal development and preventing iron deficiency anemia during pregnancy
Side effects and interactions
- Gastrointestinal side effects: nausea, vomiting, diarrhea, constipation, and stomach cramps
- Interactions with medications: antacids, proton pump inhibitors, and tetracycline antibiotics can reduce iron absorption
Precautions and contraindications
- Iron overload: excessive iron intake can lead to iron toxicity, so it's essential to follow the recommended dosage
- Hemochromatosis: individuals with this genetic disorder should avoid iron supplements, as they can exacerbate the condition
