I posted a study here somewhere recently showing that olive leaf extract (which I take for b.p.) raises glutathione. I take a cruciferous veggie extract from Life Extension every day because broccoli has been shown to help you make non-cancer causing estrogen metabolites instead of cancer-causing ones. Cruciferous veggies contain cysteine so I am always full up on cysteine (amino acid test showed 103% of cysteine...a tad over but not enough that anyone was concerned). I don't have time to respond to your note more that this right now.
