Administration Instructions
- Give the drop at the same time each day to establish a routine and improve adherence 1
- Place the drop directly into the infant's mouth using the dropper that comes with the product 1

Important Safety Information
- Verify the concentration is 10 mcg per drop (400 IU per drop) before administering to prevent dosing errors 1
- Do not exceed 1 drop daily unless specifically directed by your pediatrician 1
- Avoid using extremely concentrated high-dose vitamin D products, as vitamin D toxicity, though uncommon, can occur with excessive dosing 2
Who Needs Vitamin D Supplementation
- All exclusively breastfed infants require vitamin D supplementation, as breast milk contains insufficient vitamin D 1
- Formula-fed infants consuming less than 1 liter (approximately 32 ounces) of fortified formula daily also need supplementation 1, 3
- Formula-fed infants consuming adequate fortified formula (≥1 liter/day) receive sufficient vitamin D from formula alone and may not require additional supplementation 3
Monitoring
- Routine monitoring of vitamin D levels is not recommended for healthy infants receiving standard supplementation 1
- Periodic vitamin D monitoring may be indicated for infants on long-term supplementation or those with malabsorption conditions 1
Special Populations
- Preterm infants may require higher doses while in the neonatal intensive care unit, but standard 400 IU/day is appropriate once discharged home 1
- Infants with liver or kidney disease may need special attention to vitamin D intake and should be managed in consultation with their pediatrician 2
