Children
Children have much lower ULs than adults — 40 mg zinc UL drops to 4–9 mg for young children. Learn which supplements are appropriate for kids, at what ages, and where parents commonly overdose.
Children have lower body weight and different tolerable upper intake levels than adults—for example zinc UL for young children can be single-digit mg/day compared with 40 mg/day for adults in FDA DRI tables. Adult gummies, elder stacks, and “immune” powders are dangerous when shared casually. Pediatric supplementation should be clinician-directed; NutriAudit is primarily designed for adult stacks, but the principle remains: never scale adult habits down without medical dosing.
| Nutrient | Adult UL (reference) | Pediatric note | Risk |
|---|---|---|---|
| Zinc | 40 mg/day adult | Much lower child UL bands | Nausea, copper competition |
| Iron | 45 mg/day adult | Toxicity risk lower doses | Fatal overdose possible |
| Vitamin D | Lower child UL bands | Liquid drops easy to overdose | Hypercalcemia |
| Melatonin | Not a vitamin UL | Hormonal sensitivity | Behavioral changes |

Buy pediatric-formulated products only. Adult multis are not proportional math.
Lock supplement cabinets. Iron-containing products are poisoning hazards.
Avoid elder immune stacks for kids. Herb safety data is weak in pediatrics.
Coordinate with pediatrician. Growth, labs, and diet guide decisions.
Parents sometimes share magnesium powders or sleep gummies—NutriAudit messaging encourages separating household stacks.
Teen athletes copying influencer stacks need coach + clinician oversight.
Adult gummies and melatonin trends leak into pediatric use without appropriate mg/kg thinking. Iron-containing vitamins are poisoning risks for toddlers—store like medications.
Teen athletes face different pressures (creatine, pre-workout) that need coach and pediatrician alignment.
Pickier eating phases often resolve; chronic supplementation should follow pediatric dietitian guidance, especially fat-soluble vitamins where errors accumulate.
School nurses and camps need accurate ingredient lists for allergy and seizure medication interactions.
Dose matters; chronic high doses still cause GI issues—pediatric guidance.
They are candy-like—overconsumption risk and sugar content matter.
Only if indicated—mercury/purity and dose are pediatric questions.
Only under clinician guidance—not casual retail dosing.
Use NutriAudit to audit your full stack for hidden overlaps.
Audit your supplement stackDisclaimer: NutriAudit is a decision-support tool designed to help you review your supplement stack for potential duplicate, conflicting, or excessive ingredients. It is not a substitute for professional medical advice, diagnosis, or treatment.
