Who was Carey A. Reams?
A lifelong interest in patterns within living systems
Carey A. Reams (1903–1985) is associated with the development of the Reams Biological Theory of Ionization. Organisations preserving his teaching describe interests spanning agriculture, plant nutrition, mathematics, biophysics and biochemistry.
Published materials and course transcripts show that he spent decades presenting ideas about nutrition, agriculture and biological systems. Claims about his formal titles and qualifications vary across secondary sources, so this page does not rely on disputed credentials.
His personal account of 1931
According to accounts attributed to Reams, he believed that central numerical concepts later used in RBTI came to him during a period of fasting and prayer in 1931. We include this respectfully as part of his personal and faith history—not as proof of scientific validity.
Clinic perspective: “His theory has never been proven wrong over tens of thousands of people and will always remain so even to this day.” This statement reflects the clinic’s belief and has not been independently established by clinical research.
Key milestones
A simple historical timeline
The dates below focus on documented publications and teaching records, with personal accounts clearly labelled.
- 1931
A personal turning point
In accounts attributed to Reams, he connected the beginnings of his core numerical ideas with a period of fasting and prayer. This is part of his personal faith story, not independently verified scientific evidence.
- 1975–77
Recorded teaching sessions
Transcripts preserved from this period document courses in which Reams taught the framework he called the Biological Theory of Ionization.
- 1978
A published account
Reams published Choose! Life or Death, setting out his ideas for a wider audience. Library catalogues record the book as a 1978 publication.
- Today
A complementary practice
Some practitioners continue to use RBTI measurements as one source of information when discussing nutrition and lifestyle, alongside appropriate medical care.
Inspiration from nature
Balance as a guiding idea
RBTI developed partly from observations and analogies drawn from agriculture: soil, plants and other living systems depend on suitable conditions and available nutrients. Later practitioners extended this balance-focused way of thinking to nutritional assessment.
The plant-to-human comparison is a conceptual model. It does not establish that soil chemistry and human physiology operate in the same way, and it should not be interpreted as a medical mechanism.

Personalised nutritional guidance, with clear boundaries
Some complementary practitioners use RBTI measurements as part of broader conversations about food, hydration, mineral intake and lifestyle. At Mandurah Health Regeneration, the focus is on personalised nutritional guidance and helping clients better understand the wellness information discussed during their consultation.
Historical context: This page uses careful wording based on the published record of Reams’ 1978 book, archived teaching transcripts from 1975–77 and later practitioner accounts. Statements drawn from Reams’ personal story, rather than independent documentation, are clearly identified.
