Women with a history of childhood trauma have higher levels of a natural antioxidant called bilirubin, which might be their body’s way of fighting back against long-term stress.
Scientific Claim
Bilirubin levels are elevated in postpartum women with a history of childhood maltreatment, potentially reflecting an adaptive antioxidant response to chronic stress exposure.
Original Statement
“In study cohort II, untargeted metabolomics indicated higher serum levels of bilirubin IXa, another metabolite with antioxidant capacity, among women with CM compared to non-exposed women (35). Bilirubin is an end product of heme degradation by heme oxygenase-1 (HO-1), an enzyme with known anti-inflammatory and anti-oxidative properties.”

The Association of Childhood Maltreatment With Lipid Peroxidation and DNA Damage in Postpartum Women
The study looked at stress markers in new moms who were mistreated as kids, but it didn’t check bilirubin at all — so it can’t say whether bilirubin goes up. It did find signs of body damage from stress, not protection, which doesn’t match the claim.
