Are bisphenol S and bisphenol F as bad as BPA for the brain?
Yes. Research shows that BPS and BPF are bisphenol analogues that carry similar toxicological risks to BPA, making them poor replacements for consumer products.
What's actually in it
When manufacturers remove BPA (bisphenol A) from products, they often replace it with BPS (bisphenol S) or BPF (bisphenol F). These are known as bisphenol analogues. They are chemicals used to make plastics and resins that act in the body much like the original BPA.
Because they are structurally similar to BPA, they are not a safer choice. They are often found in the same types of consumer goods, including toys and personal care products, as noted in a 2026 study in J Expo Sci Environ Epidemiol. These chemicals are designed to perform the same function as BPA, meaning they can leach into your food or environment just as easily.
What the research says
The scientific community treats these alternatives with the same caution as the chemicals they replace. A 2026 study in Food Chem Toxicol conducted a risk assessment on these analogues and confirmed that they present cumulative toxicological risks. This means your total exposure to these chemicals adds up to a significant health concern.
Other peer-reviewed research highlights the broad impact of these substances. A 2026 study in J Endocr Soc linked prenatal exposure to bisphenols with serious health outcomes like gestational diabetes. The science is clear: swapping one bisphenol for another does not solve the problem of chemical exposure.
