True Health Mastery

Amazon 5-Star Reviews: 

"A Must Read and Household Resource. True Health Mastery is not for the faint of heart. It is a no-nonsense, scientific and research-based treatise on the wide range of issues and influences that impact one's understanding and personal implementation of true nutrition as the foundation for optimal health. It will soon become an invaluable household resource." C.T.

"Fantastic. This was a great book. The details about how your body functions on a microscopic level shed a whole new light on what it means to be healthy." J.B.


"Many thousands of people are taking supplements of poor quality. Chances are, those supplements may be doing more harm than good, creating inflammatory conditions due to the biological incompatibility of synthetic vitamins. The types of minerals used by many manufacturers cut production costs but are poorly absorbed. Nutrient deficiencies are one of the major causes of many degenerative diseases millions of people suffer from today, and that includes deficiencies due to poorly formulated supplements."
