I found that curcumin and grape seed extract are beneficial for UC, grape seed along with ubiquinol even helps relieve my eyes after undergoing several eye surgeries.
Butyrate works wonders but I don't take it directly. I mix powdered psyllium seed with my oatmeal each morning and, taken along with probiotics, seems to act as a wonder drug for me. Gut bacteria break down psyllium seed into butyrate that nourishes the cells in the colon. It feels almost like plaster of paris to seal up my 'leaky gut'.
Sulforaphane may or may not be the best antioxident but it is out of the question for me. I am allergic to cruciferous vegetables and they trigger severe symptoms.
Great tip on the ubiquinol (CoQ10), I have found that helped me too in the past. taking butyrate usually doesn't have a direct effect. The only brand that does that I think is Tesseract Probutyrate and it's expensive. Psyllium seed is an amazing food for building butyrate by feeding short chain fatty acid producers. Unfortunately I can't tolerate it, it goes right through me, but I did try it for a time too.
Sorry to hear about
cruciferous vegetables doing that to you. Is it the fiber, or something else? Sulforaphane is one of the best reducers available because of where it sits on the hierarchy of redox potentials. Butryate helps outside of the cell by neutralizing peroxide that sits in the colon. Sulforaphane reduces peroxide within the cell, and so do CoQ10 and grapeseed. I've been working with the redox theory for about
a month now and the positive changes in my condition have been dramatic.
