Nutrition Response Testing

Nutrition Response Testing (NRT) is a safe, non-invasive method used to find the root cause of health problems. It works by testing the body’s autonomic nervous system, which controls many of your body's essential functions. Using principles from kinesiology, human physiology, biology, and nutrition, NRT helps us understand how your body is functioning at a deeper level. By evaluating your body's responses, we can identify which organs, tissues, or glands are under stress or not functioning properly. Once we know this, we can create a personalized plan to nutritionally support those areas, helping your body heal and restore balance.

Individually Designed Clinical Nutrition Program

At OWHN, we create a personalized nutrition plan that’s tailored specifically to your needs. Once we identify the root cause of your symptoms, we develop a plan that helps your body repair itself and become healthier. We use high-quality whole-food supplements chosen just for you, to target the exact areas that need support. Our goal is to help you feel better and achieve lasting health through natural solutions.

Uncover the Root Cause with Nutrition Response Testing (NRT)

Through Nutrition Response Testing (NRT), we identify the root causes of your health issues by evaluating how your body responds to six key stressors that contribute to its breakdown. Left unaddressed, these stressors can lead to chronic symptoms and eventually, disease. At OWHN, we focus on "well care", not just temporary relief or symptom management. Our goal is to work with you to uncover the underlying causes of your health concerns and apply proven, natural solutions that restore your body’s vitality and promote long-term wellness.

    I can’t say enough about Optimal Whole Health and Nutrition and its family. I started with what I felt was several health issues about 12 weeks ago. I am now happy to say that I feel so much better. Right from the first week I slept so much better than I ever did. I don’t have body aches anymore. My energy is back to when I was young. I am so satisfied with them. They are very helpful and kind.

    After years of struggling with exhaustion and stomach issues—mostly related to food and diagnosed as IBS—I finally decided to give Optimal Whole Health & Nutrition a try. Despite trying every supplement you can imagine (probiotics, colostrum, etc.) and seeking help from a gastroenterologist, I was always told it was just IBS. But I knew there was something deeper going on.


    The past 3 years of extreme fatigue had been especially tough, but since starting with OWHN, I’ve noticed a huge improvement. My energy levels have significantly increased, and I’m now able to handle stress much better. One of the biggest wins has been with meal planning. I’ve finally stopped overcomplicating it and realized that simple, balanced meals are the key.


    If you’re struggling with chronic fatigue, gut issues, or just feeling like you can’t get to the root of your health problems, I highly recommend giving OWHN a call. It’s made all the difference for me!

    I started going to OWHN to get better control over my sugar levels and also to feel better. In the past, I've tried western medicine and doctors - medicine that made me feel sick, it kinda worked but it messed my whole system up. I felt severe pains in my stomach along with feeling nauseated. It messed with my overall gut health too. Since coming to OWHN I've dropped 100 points in glucose levels and maintained these levels! Overall, I am feeling much better. My gut health is good now and I just feel much healthier and more energetic. I highly suggest trying a more natural route over the traditional route. I've already told numerous people how it has helped me. It's healthier and you feel way better. IT WORKS!

    Before coming to OWHN I wasn't feeling well at all. I was very worried something was drastically wrong within the body. I experienced 2 weeks of nausea and was unsure what to do.  I did not want to see a medical doctor and have prescriptions shoved at me. I wanted my body back on track, and I strongly feel pills only mask the problem, I wanted to heal.


    When I initially joined OWHN, I was taking OTC Pepto Bismol, antacids, along with over 25 different supplements without any change in energy or body healing - and now I’m only on 5 whole food supplements from OWHN and an amazing healing process has begun!

    Since being on OWHN Supplements, all my morning pain is GONE. I am eating properly, by implementing protein, healthy fats and carbs that are discussed in nutritional coaching - I am becoming increasingly aware of the proper fuel my body needs through these wonderful instructional sessions. I changed my diet, and it has drastically changed my body and energy levels, even my skin feels different; and people are noticing, especially my hairdresser and my masseuse, both of whom I see regularly. My nervous system is healing and it's affecting me greatly. I’m implementing breathing exercises to increase calm and manage stress levels.

    My body has begun to tighten; I notice a difference when looking in the mirror at my overall form, and I am gaining energy, plus my sleep pattern is gradually increasing.  Healing takes time.  It doesn’t happen overnight!  But this is the type of time I am willing to put in for my health and longevity …. and it's working!!!!


    If you are thinking about going to OWHN, I highly recommend it. I would say put in the time and work at it, and you'll see results and meet all the goals you hope to achieve!  I AM!!!!!!

    I ate anything I wanted and made excuses for what I wanted to eat to fit into my low-card diet even if it wasn't low-card. Now, I am very aware of the food and the way it's prepared, that I eat. I am making more of my dinners form scratch with natural ingredients. I am educated to the toxins and chemicals that are in foods and I stay away from them.

    My daughter Gloria had difficulty concentrating and focusing for any period of time. Her teachers said she was impulsive. For the first time in Gloria's 4 years of school, the teachers not only have seen a huge improvement but also say that Gloria is a "pleasure" to work with. As a mom, I feel Gloria has always had qualities that people didn't see. After her diet change, her teachers finally saw those wonderful qualities.

    My diet was terrible. I was constantly played by Allergies, most of which had never been identified. I had a Sinus infection almost every month. My energy level was mostly down. My diet is heathier now that I know which foods to avoid... I've had 2 Sinus infections in 6 years. The amazing part is that I worked through them in 3 days instead of the ongoing 11 days of Antibiotics which upset my stomach and my yeast imbalance. The energy level is back to what it was in my 40's. I'm now 66.

    My moods were getting worse and worse right before my cycle. Each month, a new day was added to the already many days of moodiness. My patience was short and my temper blunt! I didn't like myself and that made me not want to be around anyone. Now, well let's see. Each day seems better than the last. Each month there is less moodiness. I feel better about my appearance. I feel more active and more social. I feel I can control my temper now. I know that it will take more time to get to the 100% I want to be, but now I also know I can do it!
