What is evidence-based nutrition?

Our protocols are based exclusively on high-quality scientific research.

We strive to stay current with the latest scientific conclusions.

We depend on laboratory results and clinical diagnoses to identify  functional imbalances.

We track symptoms and laboratory markers in order to gauge health.

All prescribed therapeutic foods and supplements are thoroughly investigated for clinical efficacy and product quality using professional databases.

It is impossible to efficiently use nutritional supplements without these tools.

We use powerful nutrition software to package our sophisticated dietary protocols into a user friendly product.

Our protocols are personlized, customized, and easy to follow for every client.

"The personalization of care achievable through the functional medicine approach is the only real solution to the crisis of chronic disease facing us today.  However, practicing this form of medicine is difficult, complex, and requires higher standards of decision making by clinicians.  The functional medicine approach to diagnoses demands not only that we determine what disease the patient is suffering from, which can be challenging, but also what the patient's underlying physiological dysfunctions are, and their causes, which is a complex process.

David S. Jones, MD
