Hi Rich- My naturopath/NP suspects I am very toxic and have methylation issues based on my history and sensitivities and wants to treat toxicity before treating for chronic lyme disease (my history is FMS 1998, optic neuritis 2006, neuro degen symptoms since 2006 (negative for autoimmune and MS), positive for lyme (IGENX bands 41,31). I had growing sensitivies/chemical sensitivity developing before onset of "FMS." I had my glutathione levels tested by Great Plains Labs. They tested in the normal range at 913.00. This was the Copper Zinc Profile plus Glutathione test. Does this indicate my glutathione levels are good? Can you have good glutathione levels but still have methylation issues?
