Related to this topic, if you have IBS/IBD, some interesting research been coming out in the last couple of years indicating that low vitamin D may play a role in this issue as well. This [1] 2015 study found 82% of people with IBS had low vitamin D levels relative to 31% in the control group. This [2] 2016 one proved causation of vitamin D supplementation improving symptoms, by randomly splitting into two groups and treating only one. This [3] speculative writeup by the Vitamin D Council in 2014 discusses some possible mechanisms of action.
This seems like such low-hanging fruit that it was extremely surprising to me that this is at the cutting edge. Causes and cures for IBS are not clear and one third of patients find current treatments unsuccessful [4]. But the above doesn't seem to be well known in online discussion because it's so new, and my gastroenterologist didn't bring it up at all either.
