is selenium part of the glutathione peroxidase enzyme system PRDX6 dictates ferroptosis sensitivity by directing cellular utilization: Molecular Cell Proposed catalytic mechanism of glutathione
Description
Works as an antioxidant

Thats why IV therapy often works faster than oral supplements

A detailed mechanistic study suggests that the spirocyclization occurs the formation of selenoxide intermediates

It plays an essential role in energy production , cellular repair , metabolism , and gene expression
