Unfortunately, instead of using scientific studies to reinforce the efficacy of his program, Crook uses these testimonials as his major source of proof. When Crook cites literature, it is often from questionable sources at best, such as the Journal of Orthomolecular Medicine .

Inconsistencies are also abundant.

Unsubstantiated statements are laced throughout this book. Health Considerations Interestingly, Crook prefaces his book by using a disclaimer. Yet, specific prescription recommendations are given. Crook recommends 100,000 to 300,000 units of Nystatin four times daily for infants and young children. For adults, he routinely recommends one million units.
