Most people know that nutrition affects their health. What most people don’t know is how to identify exactly which nutrients their body is deficient in — and in what combination, sequence, and dose those deficiencies need to be addressed for their unique biology.
That’s the problem Nutrition Response Testing was designed to solve.
NRT is a structured, systematic nutritional assessment process developed through decades of clinical application on tens of thousands of patients. It is used by thousands of healthcare practitioners across the United States — including chiropractors, naturopathic doctors, and integrative health providers — as a tool for identifying the nutritional root causes of chronic health complaints.
Nutrition Response Testing does not diagnose disease, prescribe medication, or replace medical care. It is a nutritional assessment and support system — used alongside, not instead of, appropriate medical evaluation and treatment.
The Analysis
The analysis is performed through the body’s autonomic nervous system — the part of the nervous system responsible for regulating the function of every organ and gland in the body.
NRT maps specific reflex points on the surface of the body — each of which corresponds to a specific organ, tissue, or physiological function. These reflex points are derived from neurological reflexes and acupuncture meridian points — systems that have been studied and applied clinically for decades.
How the testing is performed:
The result: A precise map of which organ systems are under nutritional stress — and exactly which nutritional supplements, in which combination and sequence, your body is indicating it needs.
The Personalized Health Improvement Program
Based on your analysis findings, a completely individualized nutritional support protocol is designed — specifying:
NRT evaluates the functional nutritional status of major organ systems and physiological functions throughout the body — identifying areas of nutritional stress that may be contributing to a wide range of health complaints.



What makes Designed Clinical Nutrition different:
The nutritional support program used in NRT is called Designed Clinical Nutrition — and it is fundamentally different from the supplements found on store shelves.
Your first visit begins with a thorough health history review. We take time to understand your current health concerns, symptoms, dietary habits, medications, supplements, and health goals before proceeding with the analysis.
Your provider performs the NRT analysis — systematically evaluating reflex points across your body to map areas of nutritional stress. The process is non-invasive, pain-free, and typically takes 45-60 minutes for a comprehensive initial analysis.
Based on your analysis findings, your provider designs a personalized whole food nutritional supplement protocol — specifying exactly which supplements to take, in what doses, and in what sequence. You will receive a clear, easy-to-follow program.
Follow-up visits are an essential part of the NRT process. At each visit your analysis is repeated — allowing your provider to monitor your body’s response, confirm that the protocol is working, and make adjustments as needed. Most patients are seen monthly — though visit frequency varies based on individual needs.
NRT works in layers — addressing the most critical nutritional imbalances first, then progressively working through additional layers as your body heals and responds. This systematic, sequenced approach is what distinguishes NRT from generalized supplementation.
Important note: NRT is not a passive program. The results you achieve are directly related to your commitment to following the protocol as designed — including the dietary recommendations, supplement schedule, and follow-up visit schedule.

Nutrition Response Testing is a non-invasive system of analyzing the body’s autonomic nervous system responses to identify underlying nutritional deficiencies and imbalances. Developed by Dr. Freddie Ulan, DC, CCN, it uses a form of muscle testing to evaluate the functional status of organs and systems — and produces a highly personalized whole food nutritional support protocol based on the findings.
No — Nutrition Response Testing does not diagnose or treat disease. It is a nutritional assessment system used to identify nutritional deficiencies and imbalances that may be contributing to health concerns. It does not replace appropriate medical evaluation or treatment.
Standard blood work measures specific markers in the bloodstream — typically designed to detect disease. Nutrition Response Testing evaluates the functional nutritional status of organ systems through the body’s own nervous system responses — often identifying imbalances that standard panels do not detect. The two approaches complement each other and are both used within LifeWorks’ integrative care model.
NRT uses Designed Clinical Nutrition — concentrated whole food supplements manufactured to preserve active enzymes and co-factors. These are distinct from synthetic vitamins and are selected specifically based on your individual NRT analysis findings.
NRT is an ongoing process. Most patients begin with monthly follow-up visits — though frequency varies based on individual needs and the complexity of the nutritional imbalances identified. Your protocol is monitored and adjusted at every visit as your body responds.
