Iron is one of the few nutrients where kids can come up short and where too much can be dangerous. Here's how to decide whether your child's multivitamin needs it.

Do kids need iron in their multivitamin?
Most kids don't need iron from a multivitamin if they eat iron-rich foods. Needs are highest in infancy and the teen years, especially for girls[1]. Iron is also risky: federal rules require iron-containing supplements to warn that accidental overdose is a leading cause of fatal poisoning in children under 6[2]. Ask your pediatrician before choosing an iron-containing formula.
Caveat: Needs vary a lot by age, diet and health history. A blood test, not a guess, is the best way to know whether your child is low.

How much iron do kids need?
These are the NIH's Recommended Dietary Allowances for iron[1]:
| Age | RDA (mg/day) | Upper limit (mg/day) |
|---|---|---|
| 7–12 months | 11 | 40 |
| 1–3 years | 7 | 40 |
| 4–8 years | 10 | 40 |
| 9–13 years | 8 | 40 |
| 14–18 years, boys | 11 | 45 |
| 14–18 years, girls | 15 | 45 |
Iron is found in meat, poultry, fish, beans, lentils, tofu and iron-fortified cereals. Many kids who eat these foods regularly meet their needs without a supplement.
Which kids are most at risk of low iron?
- Infants, especially those born preterm or at low birthweight[1]. The AAP recommends iron supplements for exclusively or mostly breastfed full-term infants from 4 months until they eat iron-containing foods[1].
- Toddlers. The NIH reports that about 8% of US toddlers are iron deficient[1].
- Teen girls, whose needs jump to 15 mg a day once menstruation begins[1].
- Vegetarian and vegan kids. Iron needs are estimated to be 1.8 times higher on vegetarian diets[1], and the AAP lists iron among the nutrients to plan for on plant-based diets[3].
- Very picky eaters who avoid meat. See Vitamins for Picky Eaters.
Why is iron dangerous for young children?
This is the part every parent should know. The NIH reports that between 1983 and 2000, at least 43 US children died from swallowing supplements containing high doses of iron[1]. That's why the FDA requires this warning on solid oral supplements containing iron[2]:
"WARNING: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately."
Poison control experts note that adult and especially prenatal multivitamins contain far more iron than children's products. Children's gummy and chewable multivitamins usually contain little or no iron[4]. The biggest household risk is often a parent's own iron pills or prenatal vitamins, which can look like candy to a toddler[4].
How should you choose, and store, a kids' multivitamin?
- Read the Supplement Facts. Check whether iron is listed and how much. If you see the iron warning above, treat the bottle with extra care.
- Don't stack iron sources unless your pediatrician tells you to, such as a multivitamin with iron plus an iron drop plus heavily fortified cereal.
- Store every supplement up and away, including yours. Keep them in the original child-resistant container and out of sight[5].
- If a child swallows iron pills, call Poison Help at 1-800-222-1222 right away. Don't wait for symptoms[4].
The honest summary
- Iron needs peak in infancy and the teen years, especially for girls[1].
- Most kids who eat iron-rich foods don't need iron from a multivitamin.
- Iron overdose is a leading cause of fatal poisoning in kids under 6[2]. Store every supplement safely.
- Suspect low iron? Ask for a test before adding a supplement.

Frequently asked questions
Should my toddler take a multivitamin with iron?
Only if your pediatrician recommends it. Toddlers are at higher risk of low iron[1], but children under 6 are also the ones most at risk from accidental iron overdose[2]. A blood test can clarify whether they need it.
What are signs of low iron in kids?
Low iron may not cause obvious symptoms early on. Paleness, tiredness and irritability can happen with iron-deficiency anemia, but they're nonspecific. Ask your pediatrician about screening.
How much iron is too much for a child?
The upper limit is 40 mg a day for children up to age 13 and 45 mg for teens[1]. Accidental ingestion of iron pills, especially adult or prenatal ones, is a medical emergency[4].
Do gummy vitamins have iron?
Many children's gummies contain little or no iron[4], but formulas vary. The Supplement Facts panel is the only reliable way to know.
What should I do if my child swallows iron pills?
Call Poison Help at 1-800-222-1222 right away, even if your child seems fine[4].
