Study: Maintaining High Blood Levels of Vitamin D Controls Inflammatory Bowel Disease (IBD)Adding to the importance of maintaining high blood levels of vitamin D, a new meta-analysis of 18 human random control trials for controlling inflammatory bowel disease (IBD) was published November of 2018. The researchers in China focused on Crohn’s disease (CD) and ulcerative colitis (UC), both categorized under the heading of IBD. According to the background data of their report, there are at least 3 million sufferers in Europe and half that many in the USA. Evidently, the researchers' concern was that Asian nations are experiencing a rise with IBD now. Irritable Bowel Syndrome (IBS) is much more common with some of the same chronic symptoms as IBD, though less serious. Therefore the results of this meta-analysis apply to IBS sufferers as well. The fact that IBD tends to be chronic and incurable by mainstream medicine led to their undertaking this review. They wanted to determine if supplementing vitamin D could prevent inflammatory gastrointestinal tract diseases, create remissions, and maintain them.
