However, sustained high doses, overdose, fasting, alcohol use, or pre-existing liver disease can overwhelm glutathione reserves, increasing risk of hepatotoxicity and oxidative stress
They play a supportive role by helping maintain skin repair and resilience, complementing more powerful active ingredients rather than replacing them

Poor absorption in the body means only a small amount of glutathione reaches the cells where it is needed most, thereby limiting its potential therapeutic effects
Amplite Fluorimetric Glutathione GSH/GSSG Ratio Assay Kit Green Fluorescence When cells are exposed to increased levels of oxidative stress, GSSG will accumulate and the ratio of GSH to GSSG will decrease
N-Acetyl Cysteine (or NACE) is the precursor to glutathione
