We offer two courses in Reams Biological Theory of Ionization (RBTI), a system for evaluating the patterns and relationships found within body chemistry. RBTI helps us better understand where imbalance may be developing and how the body is responding. These insights can then be used to make more informed decisions about diet, lifestyle, and supplementation, with the goal of supporting greater balance, improved function, and more lasting health.
