It is synthesized in the liver and is found in high concentrations in almost every cell in the body

The optimal timing for oral glutathione is 12 hours before drinking begins (to pre-load hepatic reserves), immediately before bed (to support overnight acetaldehyde clearance), and upon waking (to address residual oxidative stress)

These opposing effects highlight how the net impact of the crosstalk on radiosensitivity is determined by specific molecular contexts, presenting both a challenge and an opportunity for personalized radiosensitization strategies
