Irritable Bowel Syndrome (IBS) is a digestive related disorder that effects around 25 and 45 million individuals in the United States, with 67 percent of those being female. Why am I discussing looseness of the bowels, stoppage, and stomach torment unexpectedly when you came here to read about vitamin D? It isn't that quite a bit of an extend. Surprisingly high vitamin D supplementation can decrease the side effects of IBS! You can add your stomach related tract to the list of things you never thought would be influenced by how much daylight you get.
