I really don't know if there is a real IBD vitamin d connection or not, conflicting info of course.
There are lots of people in the middle east with low D, IBD is increasing but not rampant as far as I can find.
You would think it would be epidemic,so other westernization factors probably contribute.
But just started to rub 5000 iu on my chest, as opposed to oral, figuring that might be a more
natural way to get it.
Turns out even vitamin d from the sun takes about 48 hours to absorb, so possibly one reason
for even people in calif with high sun exposure and low D levels is showers/soap/detergents.
It is also interesting that vitamin d is made from cholesterol, many UC people have low cholesterol.
Anyhow watch this video or just read the transcript.
Just starting to look into this, if taken orally first goes to liver then to kidneys to be converted to active form.
If from skin, goes directly to kidneys and bypasses the liver as far as I find at this point.

of course it may have everything to do with your colon VDR expression regardless of serium D status.
