@
caledonia Thanks again for all the info. I will get the results of the MTHFR test on Mon but suspect 23andMe will take another few weeks. That was a great idea what you said re: cross-checking the results. I have never taken the methyl B12 or Folate so this will be totally new for me (assuming my results imply I should take them?)
I didn't really understand the CBS part but will wait for my results so I can ask you a more specific question vs. hypotheticals.
Thanks for looking up the ION test and I have not already paid for it (and only pay if I decide to do it and mail it in.) I don't believe the test kit that my ND gave me is the one with the cardio section but need to confirm that. If I am understanding you correctly, it sounds like the ION test does not measure glutathione but the Nutreval does (or are they just inferred on both tests from the other scores i.e. citric acid, etc?)
I want to do the test that in your opinion best measures glutathione and mitochondrial function (regardless of the cost of complexity of the test.) Is Nutreval similar to the Mito test that Sarah Myhill runs for people in the U.K.?
Thanks again!
