Can BPA-free plastic still cause thyroid and reproductive problems?
Possibly. A 2025 study found that early-life BPS exposure from BPA-free products causes thyroid disruption that leads to reproductive disorders in adulthood.
What's actually in it
Bisphenol S (BPS) is the most common BPA replacement. It's in "BPA-free" baby bottles, food containers, and thermal paper. Babies and young children encounter BPS through feeding products, toys, and food packaging at a stage when their endocrine systems are being programmed.
What the research says
A 2025 study in Chem Biol Interact found that early-life BPS exposure disrupted thyroid function, and this disruption cascaded into adult female reproductive disorders. The thyroid is the gateway: when it's thrown off early, the reproductive system pays the price later.
Choose glass baby bottles and avoid "BPA-free" plastics. BPS is not a safe alternative.
