* This overviews a variety of types of IBD and Vitamin D studies * IBD Studies giving a fixed amount of vitamin D have not been consistently successful * Small, short IBD studies which has the goal of getting Vitamin D in the range of 40 to 50 ng have been successful. * Many non-IBD studies with similar goals have likewise been successful * No mention appears to be made of the importance of a gut-friendly form of Vitamin D for IBD, Diabetes, Multiple Sclerosis and other health problems associated with poor guts * There appears to be no mention of the variety of non-gut methods of increasing vitamin D levels (see chart below) --- * IBS – 6 out of 7 studies shows Vitamin D helps, still want more studies – Jan 2018 * Crohn’s Disease risk increased 3 X if inadequate vitamin D level (another form is needed) – Oct 2017 * Gut-friendly forms of Vitamin D * Getting Vitamin D into your blood and cells has the following chart --- 1.

Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn’s disease, is a chronic and unpredictable characterized by alternating periods of remission interspersed with relapses. In recent years accumulating support for an immunomodulating effect of vitamin D on both the innate and adaptive immune system has been presented. Through the vitamin D receptor, the active form of vitamin D, 1,25(OH)2D, induces antimicrobial peptide secretion, decrease dendritic cell activity, and promotes Th2 and regulatory T cell development and activity. In addition, vitamin D promotes an increased ratio of anti-inflammatory cytokines to pro-inflammatory cytokines. Studies in IBD point to a role for vitamin D in ameliorating disease outcome. Suboptimal circulating levels of 25-hydroxyvitamin D are common in IBD and appear to be associated with an increased risk of flares, IBD-related hospitalizations and surgeries, an inadequate response to TNF inhibitors, a deterioration in quality of life, as well as low bone mineral density. With only few available randomized double-blind, placebo-controlled studies investigating therapeutic effects of vitamin D related to IBD, further research is necessary to determine the true therapeutic potential of vitamin D, as well as defining its optimal range in serum to achieve and maintain quiescent disease. This review aims to summarize the latest knowledge on the extraskeletal effects of vitamin D in IBD, and outlines the potential deleterious consequences of vitamin D deficiency in this patient cohort.
