The reviews on this product were largely positive and *not free*, which spurred my purchase. The packaging was good and it arrived in a timely manner. Upon receiving these, i tested them out for awhile.

I appreciated the thorough explanations of how the digestive (gastrointestinal) system works and the role of different parts of it. He also covers the ins and outs of natural supplementation to correct many digestive issues. Overall a very worthwhile read. An occasional reviewer criticizes that lack of more specific recommendations, but there are sufficient general recommendations for treatment. More specific would require individualized consultation, which a book cannot offer. I appreciated his specific information on how to find appropriate medical practitioners.
