What's the Connection?

Why the continual behavioral and health problems our society sees in children?
And more adults plagued with mysterious, ill-defined syndromes. Is there a connection among the apparent chaotic maze of problems? and solutions?


Follow the Adventure...

The story of one family merges with the search of others. A group of parents and adults with autism conditions discover the power of an older but reliable option to improve the health and life of their children and themselves. When other alternatives failed to bring the improvements they needed, they latched onto a new breakthrough in digestive enzyme technology. They steadfastly remained hopeful while working against a resistance to change, striving to use and refine this new-found alternative.

Feel the Joy!

Enzyme therapy is one of the fastest emerging successful alternatives for people on the autism spectrum as well as other neurological conditions. Reports of significant improvements in health, pain reduction, language, food tolerance, socializing and other benefits emerge daily. Drawing on long-standing scientific research and trials by a wide range of families, Karen DeFelice deals comprehensively with all the information on enzymes that parents or those new to enzymes need: how enzymes work, who may benefit, what to expect, practical tested advice on selecting and introducing the right kind of enzymes, and how this can be combined with other approaches and therapies.

This unique book intertwines a great story and a wonderful adventure along with practical explanations of how to incorporate the enzyme alternative into everyday life. This is beautifully balanced with giving extensive scientific research supporting this approach.The variety of stories from different families gives many ideas and examples of how others are using enzymes today.
