Reams Biological Theory of Ionization
Learn the principles, understand the relationships, and develop practical RBTI skills.
RBTI Education with Wanda Seitz, N.D., CCII-3
What Is RBTI?
RBTI, the Reams Biological Theory of Ionization, is a mathematical system developed by Dr. Carey Reams for observing relationships within biological chemistry. Rather than looking at isolated measurements, RBTI teaches the practitioner to evaluate patterns, relationships, and changes within the biological terrain.
Why Learn RBTI?
RBTI is more than a collection of measurements and correction charts. Learning the system involves understanding how the seven measurements relate to one another, how the Ideal Equation provides a point of reference, and how patterns are interpreted within the framework developed by Dr. Carey Reams. A strong foundation helps students move beyond memorization toward a more thoughtful and systematic approach to RBTI.
Understand the Seven Measurements
Learn what each measurement represents within the RBTI system and why the relationships between measurements are central to interpretation.
Learn the Ideal Equation
Explore the mathematical foundation of RBTI and how the Ideal Equation is used as a reference for understanding balance and relationships.
Recognize Patterns and Relationships
Develop the ability to consider measurements together rather than treating each number as an isolated finding.
Build Practical Understanding
Connect foundational principles with charts, examples, and educational exercises that support continued study and practitioner development.
The RBTI Practitioner Manual
The RBTI Practitioner Manual by Wanda Seitz, N.D., brings together the foundational principles, mathematical relationships, and practical methods of the Reams Biological Theory of Ionization in one comprehensive educational resource. Designed for students and practitioners, the manual presents the system in a logical sequence that encourages understanding rather than memorization.
With original figures, charts, historical context, and practical reference materials, the manual supports both structured learning and continued study. It is designed to serve as a foundation for deeper RBTI education and as a reference for those developing their knowledge of the system.
