I am the number one vitamin D advocate there is..but I cannot get behind the assumption that D can put someone in remission for UC, reason why? I went through horrible pain all throughout my body 2+ years ago all 4 quadrants...fatigue, depression, they wanted to dx me as fibro, I kept pushing, asked for vit D test, that was the winning ticket. That said, a year later I had mild UC, 2 yrs full blown pancolitis, this was after stabilizing my levels & maintaining them.
I do recommend it highly for those who suffer the joint pain associated w/ UC...
