Poly-Vi-Sol with Iron Dosing for 12-Month-Old

For a 12-month-old male weighing 10 kg, administer 1 mL of Poly-Vi-Sol with iron once daily.

Standard Dosing

The manufacturer recommends Poly-Vi-Sol with iron for infants transitioning to solid foods, typically starting around 4-6 months of age 1. The standard dose is 1 mL once daily, regardless of weight, for children in this age range.

Iron Content and Adequacy

At 12 months of age, this child requires 11 mg of elemental iron daily according to current dietary guidelines 2. Poly-Vi-Sol with iron provides supplemental iron in addition to dietary sources. The formulation is specifically designed for children who need iron supplementation during the transition to solid foods and for picky eaters 1.

Administration Considerations

  • Can be given directly or mixed with formula/breast milk: When adding 1 mL to 2 fl oz of infant formula or breast milk, the osmolality increases by +160 mOsmol/kg water 1
  • Alternative dosing if osmolality is a concern: Give 0.5 mL twice daily instead of 1 mL once daily 1
  • No refrigeration required 1
  • Does not contain common food allergens (milk, eggs, peanuts, tree nuts, fish, shellfish, soy, wheat) 1

Clinical Context

For a healthy 12-month-old with adequate dietary iron intake, this supplementation provides additional nutritional support during a critical growth period. Recent evidence suggests that lower iron doses (1-5 mg/kg/day) are effective for treating iron deficiency anemia in infants and children 3, 4, making this supplement appropriate for both prevention and mild deficiency states.

Important Caveats

  • Monitor for adequate dietary iron sources: Iron-fortified cereals and infant formula are major contributors to iron intake in this age group 2
  • Assess milk-feeding type: Exclusively breastfed infants have higher rates of iron deficiency compared to formula-fed infants 2
  • Watch for gastrointestinal side effects: Though generally well-tolerated, monitor for constipation or diarrhea
  • Do not exceed recommended dose: The product is formulated for once-daily administration at the specified volume
