My Approach


Naturopathy

Naturopathic Medicine, or Naturopathy, is based on the belief that the body can heal itself and recover from illness if it is supported by a healthy environment. Naturopaths aid and support that healing process by incorporating a variety of alternative health methods based solely on the needs of the individual. There is no medical “playbook,” but a case-by-case examination of those seeking treatment. These therapies use the healing power of nature and are the least invasive and gentle to the body as possible.

Lifestyle

At Mark Kibyuk Health Services, our approach is to individualize recommendations so that you can achieve your health goals and feel better as quickly as possible.  Does this mean you have to change your diet overnight to something extreme? Not always but if you are in a severe state of disease, this might be necessary. We will try to make the changes small and manageable over time, so you have continued success in the future.

Technology

Naturopathic technology uses cutting edge innovation and health science to stimulate natural self-healing processes of the human body.  Naturopathic Technology can be used for body health issues (joint and muscle pains), digestive issues (food allergies, yeast imbalance, heartburn, constipation), women’s health issues (hormonal imbalance, endometriosis, menopausal), mental health issues (depression, insomnia, anxiety, chronic fatigue) and seasonal and environmental allergies (asthma, auto-immune diseases)

Tests

 

At Mark Kibyuk Natural Health Services we don’t guess, we TEST.  The human body is just too complicated to guess about ailments and treatments.  Using functional labs to understand what is happening behind the symptoms is KEY to creating a plan of action which can lead to success. We pride ourselves on providing the highest level of testing available in North America to properly assess what the underlying cause of degrading health is and recommend the best clinical path forward. We only use accredited medical laboratories that focus on patient well-being, to build strong collaborative relationships with clinicians and advance the science of wellness. Please set up a consult with us to properly assess your health concerns and set up a path forward.

The tests used most at my clinic would be:

 

Organic Acids Test (OAT)

The Organic Acids Test is an easy at-home urine test that gives deep insight into your metabolism, gut balance, vitamin status, and energy production. It’s one of the most comprehensive ways to uncover hidden imbalances affecting mood, energy, and overall health.

Use this test if you struggle with:

  • Chronic fatigue or poor sleep

  • Mood or mental health challenges

  • Autism spectrum support needs

  • Autoimmune issues or chronic illness

  • Digestive concerns (candida, clostridia, bacteria)


Vitamin D Test

Vitamin D deficiency is common in Canada and strongly linked with heart disease, cancer risk, autoimmunity, mood issues, and low energy. This simple blood test checks your Vitamin D3 levels and helps guide the right supplementation to reach (and confirm) your optimal range.

Use this test if you:

  • Have fatigue, low mood, or anxiety

  • Struggle with frequent illness or autoimmune conditions

  • Have a family history of heart disease, stroke, or cancer

  • Want to track and optimize your Vitamin D supplementation


Gut Health Stool Tests (GI-MAP & GI Effects)

These advanced stool tests give a detailed picture of your gut microbiome. Bacteria, yeast, parasites, inflammation, digestion markers, and more. They help uncover the root causes of bloating, gas, cramping, food sensitivities, and chronic gut issues.

Use these tests if you:

  • Struggle with ongoing bloating, gas, or cramping

  • Suspect candida, parasites, or bacterial imbalance

  • Have IBS, IBD, or unexplained gut symptoms

  • Want answers after trying diets or supplements with no success

Think of these tests as the treasure map you’ve been looking for guiding you straight to the source of your gut health problems.


Endo Plus Hormone Panel

The Endo Plus Panel is a comprehensive saliva and urine test that evaluates key hormones including estrogen, progesterone, testosterone, cortisol, and DHEA. It helps identify imbalances that can affect energy, mood, weight, menstrual cycles, and long-term health.

Use this test if you:

  • Struggle with PMS, irregular cycles, or perimenopause/menopause symptoms

  • Have fatigue, sleep problems, or stress burnout

  • Notice mood swings, anxiety, or low motivation

  • Suspect low testosterone, estrogen dominance, or adrenal dysfunction

  • Want a complete picture of your hormone health before choosing treatment

If you’ve been wondering whether hormones are behind your symptoms, this panel is the roadmap to answers and balance.



Adrenocortex Stress Profile (with Cortisol Awakening Response)

This saliva-based test measures cortisol and DHEA throughout the day to assess your stress response (HPA axis). It reveals whether your adrenals are functioning normally, burned out, or overactive and how stress may be affecting your energy, mood, sleep, and metabolism.

Use this test if you:

  • Feel tired but wired, or struggle with fatigue and poor sleep

  • Have trouble handling stress or notice mood swings

  • Struggle with weight gain, blood sugar crashes, or cravings

  • Experience ongoing pain, inflammation, or frequent illness

  • Suspect adrenal burnout or cortisol imbalance

Think of this test as your stress blueprint showing exactly how your body is coping, and where it needs support to build resilience.
