I am 66 yrs old, have been taking at least 1 Tbsp/d of ACV with lemon, honey and baking soda in a ginger powder tea for decades. I believe that ACV is highly beneficial for many conditions but I don't believe that it has had an impact on my ET. I continue to ingest the suggested supplements and foods, avoiding those that are listed as not recommended, yet the ET continue to progress. I do believe that a combination of all/many are helpful but cannot claim that any one is better. For the last 3 yrs, I have taken increasing dosages of CBD oil, which I must admit has had a significant improvement to a general sense of calmness and wellbeing with regards to ET.
