Insights

Vitamin C (VC) supplementation effectively treats iron deficiency anemia (IDA) in children. A daily dose of 50 mg vitamin C for 6 weeks is most effective for improving hemoglobin and ferritin levels.

Area of Science:

  • Pediatrics
  • Nutrition Science
  • Hematology

Background:

  • Iron deficiency anemia (IDA) is a prevalent nutritional disorder in children.
  • Dietary iron absorption is influenced by various factors, including vitamin C intake.
  • Optimizing treatment strategies for pediatric IDA is crucial for child development.

Purpose of the Study:

  • To investigate the efficacy of vitamin C (VC) supplementation in treating mild iron deficiency anemia (IDA) in children.
  • To determine the optimal dosage and duration of VC supplementation for IDA therapy.
  • To assess the dose-dependent relationship between VC intake and improvement in hematological parameters.

Main Methods:

  • A randomized controlled trial involving 65 children with mild IDA.
  • Participants were assigned to five groups receiving varying daily doses of vitamin C (0, 25, 50, 100, 150 mg) for 8 weeks.
  • Weekly monitoring of hemoglobin, serum ferritin, free erythrocyte protoporphyrin, and hematocrit levels.

Main Results:

  • Vitamin C supplementation alone demonstrated a significant and dose-dependent improvement in controlling IDA.
  • The most effective therapeutic outcome was observed with a daily intake of 50 mg of vitamin C.
  • A treatment duration of 6 weeks was found to be the shortest effective period for IDA therapy.

Conclusions:

  • Vitamin C supplementation is a viable and effective monotherapy for mild pediatric iron deficiency anemia.
  • A daily dose of 50 mg vitamin C, supplemented for at least 6 weeks, is recommended for optimal treatment.
  • In regions with plant-based diets, particularly during winter and spring, targeted vitamin C supplementation is advised for children in northeastern China.
