## Summary

Zebrafish exposed to DBDPE, a flame retardant found in furniture and electronics, handled an alcohol hit much worse than usual. Their livers piled up fat, their mitochondria struggled, and recovery dragged on. The cause traced back to low NAD+, and giving the fish nicotinamide riboside largely fixed the damage. It's an early animal finding, but it hints at why everyday chemical exposure might make drinking harder on the liver.

## Practical Takeaway

This early animal work suggests NAD+ levels may shape how the liver handles alcohol.
