The most significant marker, considered a gold standard, was F2-isoprostane and this was significantly more reduced by oral Acetylglutathione than with the IV glutathione.[11],[12] Oral S-Acetyl Glutathione, dosed 200mg daily for 7 days, AM IV 1400mg, single dose Serum and urine tested after 1 week of administration N=6, (4 female, 2 male, average age 45) Markers chosen are measures of Antioxidants F2-Isoprostane is the Gold Standard of oxidative stress markers Conclusion: Oral S-A GSH compares favourably to a one-time, equivalent dose of IV administered Glutathione GSH : Blood levels are lower in the A-GSH group as compared to the IV group because the A-GSH is being taken up by the cell.[13] This is substantiated by the following markers: F2-Iso : (F2- isoprostane ) measurement of redox status and oxidative stress
And our answer, based on years of experience in peptide synthesis and laboratory best practices, is just as simple
Population studies taking into account basal, absolute, and net increases of postmethionine-load homocysteine levels, in relation to dietary intake and methionine, folate, and status of vitamins B 6 and B 12 to confirm the involvement of methionine excess in both basal and postload hyperhomocysteinemia
