What is Nutrition Response Testing® 

Do you have a chronic health problem you are not addressing or haven’t been able to correct through conventional medicine? 

Is your impaired health negatively affecting your relationships, your job, your financial success, and your overall quality of life?

Do you fear your health challenges are not going to improve and will probably only worsen as time moves forward?


If you answered yes to any of the questions above and you are ready to make a commitment to do what it takes to regain your health and quality of life, then I strongly suggest you visit our office to benefit from Nutrition Response Testing. 

Nutrition Response Testing is a specialized, non-invasive, scientific system of analyzing the body by testing specific neurological reflexes to determine the underlying causes of ill-health.  When these causes are corrected through safe, natural, nutritional means, the body can repair itself in order to attain and maintain more optimum health.  Nutrition Response Testing does not diagnose or treat any disease.

Nutrition Response Testing is uniquely different from other health disciplines because it allows for a highly accurate assessment of your body's nutritional needs and the source of your ill-health.  The focus is not on the symptoms, which only appear because there is something occurring deeper inside the body which needs to be addressed.  The focus is on the stressors which cause the problems.  An individualized nutrition program will be created for you according to your Nutrition Response Testing results to fix the deeper cause.  Only the highest quality whole food supplements are used to ensure the best results.  People of all ages can benefit from this remarkable therapy.

Traditional Chinese Medicine

Traditional Chinese Medicine (TCM) is a comprehensive medical healthcare system comprised of a range of therapies, including acupuncture, herbal medicine, nutrition, cupping therapy, and exercises such as tai chi and qigong.  It has been used in Asia for more than 2,000 years.  Many people today integrate TCM into their healthcare, even if they use conventional Western therapies as well.

Acupuncture is the most commonly practiced modality of TCM today.  It has earned continued recognition and validity in the Western world for the treatment of many health conditions.  Among these are acute and chronic pain, stress, anxiety, depression, infertility, and fatigue.  During a treatment, extremely thin, hair-like, sterile needles are gently inserted at specific points on the body.  These points are at the intersection of neurons (nerve cells), which react to stimulation.  When the acupuncture needle stimulates those areas, both the peripheral and central nervous systems are activated.  That triggers the release of the body's internal chemicals, such as endorphins and enkephalins, which have pain relieving properties.

Acupuncture also has the effect of vasodilating blood vessels, meaning it increases blood flow throughout the body.  This action is so crucial for good health because blood contains so many life-sustaining substances such as oxygen, nutrients, hormones, and immune cells.  These must be transported throughout our bodies to maintain good health.  The word "qi", commonly associated with acupuncture, roughly translates to "air" or "oxygen".  Oxygen is one of the vital substances acupuncture helps to mobilize in the blood.  In addition, acupuncture assists the blood to carry waste, such as carbon dioxide and nitrogen, away from cells and into the kidneys, liver, and intestines for excretion.

A few areas where TCM can help

  • Lowers inflammation, a major cause of pain

  • Relaxes muscles, reduces soreness and spasms

  • Removes body from fight or flight state

  • Releases body's natural "feel good chemicals" such as endorphins

  • Boosts ATP production, which transports energy within cells

  • Moves oxygen through body

  • Increases healthy blood flow to reproductive organs

  • Helps to thicken the lining of the uterus for pregnancy

  • Stimulates body's natural painkillers

  • Normalizes the pressure in blood vessels of the head

  • Strengthens the parasympathetic nervous system (rest and digest state)

  • Regulates circadian rhythms, the body's sleep/wake cycle

 Eric Carpenter L.Ac. MSOM

I earned a Bachelor of Science degree in Nutrition and Dietetics at Dominican University.  I also am a 2005 graduate of the Midwest College of Oriental Medicine in Chicago, where I earned a Master of Science degree in Acupuncture and Traditional Chinese Medicine.  Additionally, I completed the Advanced Clinical Training program in Nutrition Response Testing in 2019.  Having personally experienced great benefits from those therapies, I am passionate about assisting and empowering others to reach a high level of wellness through safe, natural, and effective healthcare.


I have studied with several masters in the field of acupuncture and Traditional Chinese Medicine and spent five months in China in 2009, observing various doctors in two well-known Chinese hospitals.  I also regularly enroll in continuing education courses to further my education in the field of natural and holistic medicine.  I am a former teacher at the Midwest College of Oriental Medicine. 


I believe we all have the potential to live healthier, more vibrant and fulfilling lives and that natural therapies, such as Nutrition Response Testing and acupuncture, are incredible tools to help us reach our highest levels of health and wellness, both physically and psychologically.  By removing stressors, which block the body’s healing ability and improving the functioning of organ systems, I have helped many to rediscover health and vitality, which has resulted in a higher quality of life.



 "I suffered frequent migraines.  I got them at least on a weekly basis.  I was sick of taking so much medication and losing whole days to recover from a migraine.  I haven't had a migraine in three weeks now.  I haven't even gotten tension or regular headaches.  I'm excited at the prospect of being migraine free and doing it the natural way."

"I was experiencing shoulder pain and ankle swelling before I came for acupuncture.  My shoulder pain has decreased significantly and my ankle swelling has improved also."

-J. W.

"I was experiencing lots of pain in daily movement, bending and stretching, rolling over and picking things up.  The pain level is much lower, daily activities are much easier and I'm having to compensate much less."

-S. K.

"I was having problems with excessive heart palpitations, sinus problems, thyroid issues, intestinal problems and nervous system not functioning properly.  After being on the program for about six weeks, changing my diet and more importantly taking the cleansers and supplements, I feel nearly one hundred percent better.  I am grateful for having a caring person in Eric for helping me to get healthier."
