Represented by ferrous sulfate, these supplements have a high iron content, but some people may experience gastrointestinal irritation (such as abdominal pain or constipation) after taking them. They should be taken on an empty stomach, and their absorption rate is greatly affected by food.
2. Organic Iron Supplements
These include ferrous fumarate, ferrous gluconate, and ferrous succinate. These iron supplements have higher absorption rates and milder gastrointestinal reactions, making them suitable for those with sensitive stomachs. Some can be taken with meals.
3. Composite iron supplements
Typically contain added vitamin C, folic acid, vitamin B12, and other components to enhance iron absorption while providing additional nutrients. Suitable for pregnant women, breastfeeding mothers, or those with nutritional deficiencies.
Suitable Population and Selection Recommendations
1. Patients with iron-deficiency anemia
After confirming iron deficiency through blood tests, select an appropriate dosage (e.g., 60–120 mg of elemental iron per day) under the guidance of a doctor.
2. Pregnant women and lactating women
Iron requirements increase during pregnancy. Composite iron supplements may be selected, but excessive intake should be avoided (intake exceeding 45 mg/day may increase risks).
3. Individuals with inadequate dietary intake
Vegetarians and those on long-term diets should prioritize highly absorbable organic iron and combine it with vitamin C to enhance absorption.
Types of Iron Supplements: Which is Best?
| Form | Absorption | GI Side Effects | Best For |
|---|---|---|---|
| Ferrous Bisglycinate | High (24%) | Minimal | Most users |
| Ferrous Sulfate | Moderate (15%) | High (nausea/constipation) | Budget option |
| Heme Iron Polypeptide | Very High (30%) | Rare | Sensitive stomachs |
| Carbonyl Iron | Slow Release | Low | Children/overdose risk |
Precautions for Use
1. Avoid taking with certain foods/medications
Tea, coffee, milk, calcium supplements, and antacids can inhibit iron absorption. Take at least 2 hours apart.
2. Common Side Effects and Management
If you experience black stools (a normal phenomenon), constipation, or nausea, adjust the dosage or switch to a different type of iron supplement, while increasing dietary fiber and fluid intake.
3. Risks of Overdose
Long-term excessive iron supplementation may lead to iron deposition, damaging organs such as the liver. Regular monitoring of blood iron levels is necessary.
