BPA's "Safe" Replacement BPS Causes Liver Scarring

The chemical that replaced BPA in your "BPA-free" products is scarring your liver. Bisphenol S (BPS) drives the progression from fatty liver to fibrosis.

How BPS Scars Your Liver

A 2026 study in Toxicol Appl Pharmacol used zebrafish, macrophage cells, and human liver stellate cells to map exactly how BPS damages the liver. It works through two mechanisms at once.

First, BPS pulls macrophages (immune cells) into the liver and shifts them toward a profibrotic M2 phenotype. These reprogrammed immune cells then activate hepatic stellate cells (HSCs), the cells that produce scar tissue.

A Double Attack

Second, BPS directly activates HSCs by stimulating autophagy and forming more autophagosomes inside the cells. So BPS hits the liver from both sides: indirectly through immune cells and directly through the scar-forming cells themselves.

The result is progression from NASH (non-alcoholic steatohepatitis) to liver fibrosis. That's the step before cirrhosis and liver failure.

"BPA-Free" Means Nothing

BPS is in thermal receipt paper, canned food linings, and plastics labeled "BPA-free." It's structurally similar to BPA and now proven to cause its own serious damage.

What You Can Do

Stop trusting "BPA-free" labels. Avoid canned foods, thermal receipts, and plastic food containers regardless of what bisphenol they use. Choose glass and stainless steel. And check out non-toxic home essentials for truly safe alternatives.
