Vit D supplementation reduces fecal calprotectin and may alter microbiota composition in UC

I've seen quite a bit on H Pylori being protective against esophageal cancer too.

I was on very high dose vit D for a few months this winter. I went into remission on cyclopsorine so don't know if the vit d helped but maybe it did. I've always been very low on it.

Thanks MK. When I first looked into Vit D I remember coming across an explanation that it is not really a vitamin, it is a steroid-like hormone. So it would make sense that it has an effect on the immune system. Also remember coming across some research where they gave high dose vit D to a inpatients in a psyc hospital over some months, hoping it would help schizophrenia, it did not but there were markedly less colds, coughs etc they said.
