Are BPA-free plastic baby bottles truly free of estrogen-like chemicals?
Not always. BPS and BPF, common BPA replacements, show similar estrogenic activity in studies. Glass is safest.
What's actually in it
The science on this is clear enough to act on. Chemical exposure from this product type is real and avoidable with a simple swap.
Research on this chemical or material consistently finds exposure levels worth reducing, and safer alternatives are widely available.
What the research says
