I think this is one of the most important books I have read in a long time. If you have any background in healthcare, the first 75 pages are a review. If you have inflammatory bowel diseases-IBS, crohn‘s or UC, this book is another weapon in the arsenal of management. Which probiotic strains do you need for your specific situation? What brand? Can probiotics make you sick? Would give it a longer review if I could. 9/10
