My reduced glutathione was low, as tested with the Methylations Pathway panel. It points toward excessive oxidative stress in my body.
I think I’ve now seen 3-for-3 guys on the board report low glutathione. It’s a very small sample size, but if it bore out as a pattern, it would suggest oxidative stress as a factor in PFS. I find this interesting in terms of understanding the etiology of the disease – what is it about PFS that results in excessive oxidative stress? It could be a clue in the research process.
If anyone is thinking of testing this… the Methylation Pathways test has two main advantages over other glutathione tests:
- I believe most tests only measure “total glutathione”, which lumps the used-up stuff in with the fresh stuff. The Pathways panel reports these separately, telling a much more useful story about oxidative stress
- I believe most tests include red blood cells in the sample. Rich said this has a tendency to artificially skew the result artifically high, b/c RBC’s are a net exporter of glutathione.
There’s another marker of oxidative stress I know of: 8-hydroxy-2’-deoxyguanosine on the Metametrix Comprehensive Organix profile. If anyone has done the Organix test, can you volunteer what your result was?
As Droit indicated, direct glutathione supplementation has mostly been a failure in the CFS/ME and autistic communities, despite the fact that both diseases are charcterized by glutathione depletion (and excessive oxidative stress). But I’m not sure anyone has figured out exactly why it usually (not always) fails. More success has been seen from supplementing precursors (i.e., NAC), and through the Simplified Methylation Protocol (SMP), which primarily features a combination of 2mg vitamin B12 and 400mcg 5-MTHF (“methylfolate”), which helps kick the methylation cycle into gear and has been shown in research to somehow or another spur glutathione production.
I’ve actually been taking the SMP as part of my supplements. I can’t say it’s changed how I feel, but I wouldn’t necessarily expect it to – I think oxidative stress is more likely to be another symptom, not the cause of PFS. (It’s a symptom worth fixing, though, b/c oxidative stress ages the body and affects health in many ways, whether we feel them or not.)
