Just a quick review of my personal celery juice experiment, n=1
Top line conclusion: It failed hard. I had a very bad reaction.
Myself: ME diagnosis (Canada criteria) from 2007, verified twice. Homebound but not bedbound.
Background for experiment: lots of articles and media noise about the broad range of claimed health benefits you can get from drinking celery juice. E.g. reduce fatigue and improve thyroid function (Hashimoto's) among others.
Why did I think I would be a good celery juice candidate: I can tolerate most foods, have no food allergies. I have a stable and good digestion. I struggle with fatigue, cognitive issues and have Hashimoto's. I do not have POTS.
Celery juice experiment: For 10 straight days I drank ca 16 oz (5 dl) of organic celery juice every morning on an empty stomach. The juice was made with a slow-juicer. I drank the celery juice fresh, straight after juicing. I waited one hour before drinking or eating anything else. All this is "by the book", i.e. done correctly according to the celery juice experts online.
Results: The first 2-3 days I had some loose stools and some "movement" and noise from my belly. A little bit of bloating, but not much. From day 4 to 10 I had no problem with digestion, perfectly normal stool. From day 1 I started to feel worse. Increase in symptoms like: more fatigue, more "wired but tired", more tinnitus, more cognitive problems (concentration/memory/focus), increased heartbeat frequency (bpm).
Gradually it just got worse, day by day. My first thought was Herxheimer's reactions, then I thought about the metabolic trap theory, suggesting possible treatments could imply feeling worse for a few days. Then, the last 2-3 days was just pure stubbornness from my side. I wanted to give celery juice a proper go. When I stopped after day 10 it was a relief. I was in a really bad condition, practically bedbound.
I am now two days after "day 10" and close to being back to my baseline condition. Still not there yet. For me, celery juice was a horrible experience.
All the best,
