Darya Rose: Absolutely

In oxalate-stimulated HK-2 cells, iron levels increase, accompanied by the upregulation of ACSL4 and TFR1 expression and the downregulation of GPX4, SLC7A11, and ferritin light chain expression, along with typical ferroptosis-related mitochondrial alterations (275)

Once the molecule is inside the cell, the acetyl group is removed by internal enzymes, leaving the active glutathione ready to work

However, studies in mice show NR is more effectively taken up than NMN in some tissues, such as skeletal muscle 39 , highlighting the importance of the choice of precursor treatment depending on the intended target organ
