But yeah, I do have this worsening reaction to almost every antioxidant I've tried, my CFS symptoms go from mild to moderate while on them in a matter of less than a week.
My take is that some of the benefit of certain supplements are being lost because we tend to look for a quick fix. I recently made a post about ART, but I also mentioned supplements, so I will quote it below:
The difficulty is that you can feel more tired by resting deeply, which in itself can make things difficult, as you could almost be persuaded that you're getting worse as a result. But in time you do better, even if it means waiting for the results.
I suspect many supplements that may make us feel less energetic may have a similar effect in the long run, by preventing us from overdoing it, even if the popular supplements (which we're all mostly aware) push us faster, but possibly crash us years later. Slow and steady may indeed win the race, and if true, it would explain why there aren't as many full remissions. People don't want to go down before they can get up. In my opinion, this applies both to ART and supplements that can prevent overstimulation, or rather the more unpopular supplements.
