Mineral and Vitamin Supplementation Guidelines for Pediatric Age Groups

Vitamin D Supplementation

The American Academy of Pediatrics recommends vitamin D supplementation of 400 IU daily for infants under 12 months and 600 IU daily for children 1-18 years, with an upper safety limit of 1,000 IU/day for 0-6 months and 1,500 IU/day for 7-12 months, and a target serum 25(OH)D level of >50 nmol/L (20 ng/mL) 1, 2
Children consuming less than 1 liter of vitamin D-fortified milk daily will likely need supplementation, with upper safety limits of 2,500 IU/day (ages 1-3), 3,000 IU/day (ages 4-8), and 4,000 IU/day (ages 9-18) 1, 2

The recommended zinc supplementation is 5 mg daily for healthy children over 12 months, with an upper safety limit of 12 mg/day for ages 4-8, and 400-500 mcg/kg/day for preterm infants on parenteral nutrition 1, 3
Children with high gastrointestinal fluid losses require significantly higher zinc intake and should have zinc status monitored periodically through serum zinc and alkaline phosphatase levels, with a recommended intake of 50 mcg/kg/day, up to a maximum of 5 mg/day 3

The recommended copper supplementation is 40 mcg/kg/day for preterm infants and 20 mcg/kg/day for term infants and children on parenteral nutrition, with an upper safety limit of 0.5 mg/day, and an additional 10-15 mcg/kg of copper for children with high gastrointestinal losses 3

The recommended vitamin C supplementation is 25 mg daily for healthy children over 5 years, with an upper safety limit of 650 mg/day for ages 4-8, and whole fruits should be prioritized over juice, with juice intake limited to 4-6 ounces daily for children aged 4-6 years 1

The recommended vitamin E supplementation is 2.8-3.5 mg/kg/day for preterm infants, not exceeding 11 mg/day total, and 11-15 mg/day for children and adolescents 9-18 years, with an upper safety limit of 1000 mg/day (approximately 1500 IU/day) 4

Individuals should acquire daily vitamin and mineral requirements from natural food sources rather than supplements, with supplementation viewed as therapeutic intervention requiring safety and efficacy demonstration, and megadoses carry potential toxicity risks 1
Children on long-term parenteral nutrition need periodic monitoring of zinc, copper, and vitamin D status, and children with chronic kidney disease may require water-soluble vitamin supplementation if dietary intake doesn't meet 100% of DRI 3, 4
