Functional Medicine in Northfield

Happy Family


More than 13,000 patients treated with safe, evidenced based natural medicine.



A visit with Dr. Krystosik starts off by developing a healthy doctor patient relationship—a therapeutic partnership between the doctor and the patient. By listening to each patient’s story, drawn from a time-line of their health history, Dr. Krystosik then creates a personalized treatment plan addressing each patient’s unique needs. Patients are encouraged to take an active role in their health care by asking questions, learning how the body functions to heal itself and embracing lifestyle changes. The doctor’s role is to educate, investigate, guide, direct, encourage and protect the patient’s well-being.


The foundation of Dr. Krystosik’s healthcare is based on three important core principles; common sense, science and cooperation with nature. Dr. Krystosik looks upstream to identify the cause of ill- ness, instead of merely treating symptoms. Rather than guess, Dr. Krystosik tests the weakest body systems with functional medicine tests. Next, he identifies imbalances in the body systems, and a strategy to restore their integrity. After he interprets the test results, Dr. Krystosik provides the patient with a GPS system—and the best treatment options to help guide them through the maze of illness and back to optimal health.


Dr. Krystosik relies on what the ancient Greeks referred to as “Vis Medicatrex Naturae,” (the healing power of nature). He cooperates with nature to restore his patients back to health with nutrition, a personalized diet, herbs, vitamins, minerals, detox programs, exercise and stress-management tools. Dr. Krystosik’s ultimate goal is to help his patient become independently healthy and able to enjoy a healthy, drug free, long life—relying on their “doctor within.” Dr. Krystosik’s patient cen-tered approach allows each person to be in control of their health and wellness.

Dr. Krystosik “Dr. J” is Northeast Ohio’s Leading Expert in Functional Medicine Since 1986

Functional Medicine is based on the principle that the body is a self-healing and self-repairing. The main objective of functional medicine is to identify and correct the underlying cause of the individual’s health problem. It is a patient centered health care system rather than a disease centered system. Functional medicine requires patients to take a pro-active role in their health care and encourages a doctor/patient treatment partnership. Dr. Krystosik spends a significant amount of time with his patients carefully listening to their health history while evaluating the connections of their genetic background, work, home and playtime environment, plus diet and any other lifestyle factors that have contributed to their current health problems.

Functional medicine is a systems oriented approach to health, not a symptom approach. We connect the dots between each system of the body in order to enable the body to heal itself. We encourage you to make diet and lifestyle modifications that cooperate with the inherent healing capacity of the body.

Functional Medicine Reaches Beyond Conventional Doctor's Tools

Although it takes advantage of standard medical tests if they are necessary, functional medicine uses a set of unique science-based tests that get to the root cause of disease. For example, let’s say you have symptoms of alternating diarrhea and constipation along with frequent abdominal pain. A conventional doctor would more than likely order a colonoscopy or an endoscopy to rule out something serious, like cancer. When that is ruled out a diagnosis of irritable bowel would be made. These types of tests do not identify the underlying cause of the illness, rather they only document that there is a problem. On the other hand, in the same circumstance Dr. Krystosik would order a very detailed stool test that would determine the amount of good and bacteria living inside your gut, rule out parasites or yeast overgrowth, determine if you are digesting carbohydrates, protein and fat adequately, and much more information on the function of your intestinal tract. In addition, Dr. Krystosik would order a special blood test for hidden food allergies.

Once Dr. Krystosik received the lab test results he would prescribe a personalized diet, supplements and lifestyle modifications based on the information provided by the specific lab tests. In all chronic health problems, Dr. Krystosik provides a careful consultation and examination, and utilizes functional medicine tests to determine the underlying cause of illness. He evaluates blood, stool, urine and saliva tissues from special functional medicine tests to achieve this goal. Dr. Krystosik only orders tests that are necessary to identify the cause of your illness. Each specific test is designed to measure the function of organs and system of the body. A few of these tests are as follows: Delayed food sensitivity blood test to determine which foods are right for your body (personalizing your diet), Comprehensive Stool Test provides a detailed page report of the health of the intestinal environment, Liver Function Tests evaluates the livers capacity to detoxify toxins, (evaluation of the detoxification pathways of the liver), Hair analysis a screening tool used to determine the level of toxic metals, Saliva hormone test to determine the level of bio-available hormones, nutrient deficiency test (a blood test that determines your levels for 32 different nutrients) When necessary, several other tests are employed to determine if any body parts or systems have weaknesses, deficiencies or excesses.

The goal of Functional Medicine is to treat the person and not the disease. We strive to optimize the function of the body systems and organs by determining biochemical imbalances or "glitches" that can lead to symptoms or illness. Lastly, there are millions of people who have many symptoms of ill health but do not have a definable illness. These individuals are called the “walking wounded.” Functional medicine can help to identify the underlying cause of these symptoms even though you have no definable illness.

Why Functional Medicine Is So Important?

Conventional medicine in the United States provides the best emergency medicine in the world. We should all be thank-full for our emergency medical care system. Doctors prescribe extraordinary crisis care treatments with precision and remarkable effectiveness. The diagnosis and treatment of trauma or crisis illness such as a broken bone or pneumonia with drugs or surgery has saved countless numbers of lives.

However, problems begin when conventional medicine tries to apply emergency medical care procedures to chronic disease. The tools and procedures used for emergency care are not effective for the prevention and treatment of complex chronic disease. The truth is conventional medicine is failing miserably when it comes to chronic disease. Most conventional doctors are not properly trained to identify the underlying causes of complex, chronic disease. They’re not trained to integrate strategies like nutrition, diet, stress management and exercise to both treat and prevent these diseases in their patients. Diet and lifestyle, hidden food allergies, nutrient deficiencies, toxins and other environmental factors are glossed over superficially, or completely ignored leaving the underlying cause unchecked. Instead doctors treat the downstream effects of the above causes of disease. Functional medicine doctors go upstream to treat the underlying causes of chronic disease. We respect as well as recruit the body’s inherent capacity to heal itself. Instead of treating symptoms of illness, we improve the function of the systems of the body which provides the body the power to heal itself. Functional medicine could change and possibly even save your life.

How will you approach my problem?

First, we'll have you fill out an extensive health questionnaire which will help determine which systems of your body's are under the greatest amount of stress. Next we will request medical records from your previous doctors to find out what diagnostic tests and procedures have already been done. Once Dr. Krystosik has received all of this information he will do a thorough consultation and examination with you.

Based on the information from the health questionnaires, your consultation and examination, Dr. Krystosik will determine if any of the following diagnostic tests are necessary to determine the underlying cause of your illness.

  • Hidden food allergy blood testing
  • Amino acids blood and urine tests
  • Essential fatty acids blood test
  • Vitamins and minerals blood test for 32 nutrients
  • Comprehensive Cardiovascular Blood Screening
  • Antioxidant status tests
  • Essential Fatty Acid
  • Comprehensive Stool Analysis Test
  • Saliva hormone testing
  • Liver function test
  • Heavy metal toxicity testing
  • DNA tests
  • Celiac blood test

Finally, a report of findings consultation with Dr. Krystosik’s will provide his assessment and recommendations for your health care problem. At this time if Dr. Krystosik feels he can help you he will prescribe a personalized health care plan for your health care problem. If he feels he cannot help you, Dr. Krystosik will refer you to a health care specialist that uses conservative health care practices.

What Type of Treatments Do You Provide?

Treatment include personalized dietary and lifestyle modification, vitamin/mineral, herbal or homeopathic and other whole food supplements, detoxification programs, stress management, weight management, and chiropractic adjustments. These treatment procedures are based on the information you provide plus Dr. Krystosik’s consultation, examination and functional laboratory tests. If Dr. Krystosik determines you have a health care problem that requires drug or surgical intervention he will, of course, refer you to a specialist for this purpose. However, Dr. Krystosik believes that 90% of chronic health problems can be resolved without drugs or surgery and he has thousands of patients to prove it.
