Functional medicine efforts focus on the root causes of an individual’s condition and treats those causes. Our philosophy for optimum health is based on our belief that everyone has the potential to achieve wellness. We achieve this through practicing evidence-based medicine, using nutritional interventions, nutraceuticals, and medications when necessary.
In addition to functional medicine offerings, we also provide annual wellness exams, involving the most up to date testing and exams required for disease prevention. For patients who are in-network with us, they are able to select Functional Medicine of Idaho as their primary care provider after they establish themselves as a patient at our clinic.
