Are children's multivitamin gummies safe if they contain heavy metal residues?

What's actually in it

In a 2026 study in PLoS One, researchers found some children's gummy vitamins contained elevated manganese, a mineral your child only needs in tiny amounts. A few products had large differences by batch, so label consistency and test reporting can be important.

The same study linked higher manganese exposure from gummies to weaker neurodevelopment indicators in children.

What the research says

For children, the same study is the strongest direct evidence we have. We use it as the core support for caution.

A 2026 review in J Hazard Mater shows how heavy metals can move from polluted soil into food chains. That is useful context, but it does not prove every vitamin ingredient is contaminated.

A separate 2026 study in J Appl Toxicol focused on dementia progression in older adults. We do not use it to claim what happens to children.

For your child, ask for third-party heavy-metal certificates and follow the serving amount exactly. If no clear testing is published, skip that formula and use a different brand.
