Can plastic-related chemicals affect children's vitamin D markers?

What's actually in it

Children can meet endocrine-disrupting chemicals through food packaging, plastic food containers, dust, personal care products, and treated household items. These chemicals include PFAS, PBDE flame retardants, organophosphate esters, phthalates, and phenols.

Vitamin D is also shaped by sunlight, diet, skin tone, season, supplements, and health. Plastic exposure is only one possible factor.

What the research says

A 2026 HOME Study analysis in Environ Res measured 24 endocrine-disrupting chemical biomarkers and 3 vitamin D biomarkers in children at ages 8 and 12.

The study found that the overall chemical mixture was linked with higher total 25(OH)D, not lower vitamin D. PFAS, PBDE, and organophosphate ester mixtures were also linked with higher total 25(OH)D. Phthalate and environmental phenol mixtures were not clearly linked with total 25(OH)D.

The researchers said these changes may point to vitamin D system disruption, not better vitamin D status. So the honest takeaway is not “plastic lowers vitamin D.” It is that endocrine-disrupting chemicals may shift vitamin D markers in ways researchers are still studying.

For daily life, reduce plastic contact where it is easy. Do not microwave food in plastic. Store hot or oily leftovers in glass. If you are worried about a child’s vitamin D, ask a pediatrician about testing, diet, sunlight, and supplements.
