Nutrients that aid absorption
1. Vitamin C (ascorbic acid)
Enhances iron utilization by reducing trivalent iron to divalent iron (a more easily absorbed form).
The recommended addition ratio is typically 2–3 times the iron content.
2. Folic acid (vitamin B9) and vitamin B12
Work together to promote red blood cell production and prevent megaloblastic anemia.
Particularly suitable for pregnant women or people with nutritional deficiencies.
3. Other trace elements
Zinc: Participates in hemoglobin synthesis, but note that it competes with iron for absorption.
Copper: Assists in iron metabolism and transport, typically added in the form of copper gluconate.
Considerations for ingredient selection
1. Iron type and absorption rate
Organic iron generally has a higher absorption rate than inorganic iron, but selection should be based on individual tolerance.
Heme iron is suitable for iron-deficient individuals other than vegetarians, but allergy risks must be ruled out.
2. Dosage and Safety
The daily upper limit for iron intake in adults is 45 mg; excessive intake may lead to poisoning.
Excessive vitamin C supplementation may cause diarrhea; it is recommended not to exceed 200 mg per dose.
3. Contraindications and Interactions
Calcium and magnesium supplements may inhibit iron absorption; it is recommended to take them at least two hours apart.
Tannic acid in tea and coffee reduces iron absorption; it is advisable to avoid consuming them simultaneously.
Suitable population and scenarios
Patients with iron deficiency anemia: Dosage should be guided by a doctor, and supplementation is usually required for 3-6 months.
Pregnant and lactating women: Iron requirements increase, and supplementation should be combined with folic acid.
Vegetarians or those with unbalanced diets: Preventive supplementation with low-dose iron supplements.
