WHERE TRUE HEALING BEGINS!

A Personalized Functional Medicine Approach to Healing!

FUNCTIONAL DIAGNOSTIC NUTRITION

Hello and Welcome! My name is Mary Tufano and I am a FUNCTIONAL DIAGNOSTIC NUTRITION® Practitioner (FDN-P) and founder of THE ROOT CAUSE SOLUTION, a full-service Diagnostic Lab testing company. As an FDN Practitioner, I don't just treat symptoms. I help to uncover the root causes of your health concerns.

Helping You Heal by Addressing the Root Cause

My mission is to help you uncover the real reasons behind your health challenges—so you can stop managing symptoms and start experiencing true, lasting wellness.

I use advanced DIAGNOSTIC LAB TESTING to identify hidden imbalances in the body, whether it’s gut dysfunction, hormonal imbalances, metabolic issues, or chronic inflammation. These insights allow me to create a personalized, data-driven protocol tailored specifically to your unique biochemistry and health goals.

With a deep belief that healing starts at the root, I offer more than just information—I provide education, support, and a clear path forward. Together, we’ll work to restore balance, optimize your body’s natural healing capacity, and help you reclaim your energy, clarity, and well-being.

Feeling Like You’ve Tried Everything? Let’s Uncover the Hidden Causes Behind Your Health Struggles

Many people come to me as a last resort. They have “tried everything” and hit a wall. What they don’t understand is that they are often dealing with several levels of dysfunction in the body and these complications remain hidden from view. These hidden stressors compound over time and create Metabolic Chaos®. Symptom-free living is simply not possible until these issues are identified and properly managed. Are headaches an aspirin deficiency? Is fatigue a caffeine deficiency? In other words, symptoms are not the problem, they are the result of the problem!

My 3-Step Functional Wellness Program

As a Functional Diagnostic Nutrition Practitioner, I guide clients through a clear and empowering path to better health. My 3-Step Program is designed to uncover the root causes of dysfunction and provide a personalized roadmap to healing—so you can finally feel like yourself again.

STEP 1 - THE DISCOVERY: We begin with a thorough consultation to explore your health history, current symptoms, and wellness goals. This step helps us identify which functional lab tests will give us the most insight into what’s going on beneath the surface.

STEP 2- THE PLAN:Using advanced diagnostic lab testing, we analyze how your body’s core systems are functioning. This allows us to pinpoint H.I.D.D.E.N. stressors—those impacting your Hormones, Immune system, Digestion, Detoxification, Energy production, and Nervous system.

STEP 3 - THE JOURNEY: With your results in hand, we develop a personalized healing plan using the proven D.R.E.S.S. for Health Success® framework: Diet, Rest, Exercise, Stress Reduction, and Supplementation. This plan supports your body’s natural ability to rebalance and restore optimal health—step by step.

TEST, DON'T GUESS!

Symptoms are your body’s way of asking for help—but they rarely tell the whole story. Instead of chasing symptoms with trial-and-error solutions, functional lab testing allows us to look beneath the surface and uncover what’s truly driving dysfunction. By identifying hidden stressors affecting your digestion, hormones, detox pathways, and more, we can create a precise, personalized healing plan that supports real, lasting results. Below are some of the powerful diagnostic tools I use to help clients get clarity, take action, and reclaim their health from the inside out.

1. GI MAP STOOL TEST by Diagnostic Solutions

A cutting-edge stool test that uses DNA-based technology to assess the health of your gut microbiome. It identifies pathogens like parasites, bacteria, viruses, and fungi, as well as markers for inflammation, digestion, and immune function. This test provides a comprehensive view of your gut health, helping to uncover root causes of symptoms such as bloating, fatigue, skin issues, and hormone imbalances. It’s a powerful tool for creating personalized, targeted healing protocols.

2. DUTCH HORMONE TEST by Precision Analytics

The DUTCH (Dried Urine Test for Comprehensive Hormones) is a gold-standard test for assessing hormone health. It provides a detailed analysis of sex hormones (estrogen, progesterone, testosterone), stress hormones (cortisol and DHEA), and their metabolites. This test offers insight into hormonal imbalances that may be driving symptoms like fatigue, mood swings, weight gain, PMS, or sleep disturbances. The DUTCH test goes beyond standard blood work to reveal how your body is producing, using, and clearing hormones—so we can design more effective, personalized support.

3. ORGANIC ACID TEST (OATS) by Mosaic Diagnostics

A comprehensive urine test that evaluates over 70 markers related to gut health, detoxification, energy production, nutrient status, and brain chemistry. It offers a detailed snapshot of how well your body’s metabolic processes are functioning. The OAT is especially useful for identifying hidden issues like candida overgrowth, nutrient deficiencies, oxidative stress, and neurotransmitter imbalances. This powerful test helps uncover the root causes of chronic symptoms such as fatigue, brain fog, mood changes, and digestive problems—guiding more targeted and effective healing strategies.

4. MRT FOOD SENSITIVITY TEST by Oxford Biomedical

The MRT (Mediator Release Test) is a blood test that identifies hidden food and chemical sensitivities that may be contributing to inflammation and chronic symptoms. Unlike traditional allergy testing, MRT measures your immune system’s inflammatory response to 170+ foods and additives—helping pinpoint what’s triggering issues like bloating, headaches, skin flare-ups, joint pain, or fatigue. This test takes the guesswork out of elimination diets and provides a personalized roadmap for calming inflammation and restoring balance through targeted dietary changes.

5. MYCOTOXIN by Vibrant Wellness

The Mycotoxin test detects the presence of toxic compounds produced by mold, which can accumulate in the body and disrupt immune, neurological, and hormonal function. This urine-based test screens for multiple mycotoxins from common mold species found in water-damaged buildings, contaminated foods, and the environment. Mold toxicity is often a hidden driver behind symptoms like brain fog, fatigue, sinus issues, headaches, and chronic inflammation. This test helps uncover mold exposure and guides personalized detox strategies for deeper healing.

6. TOTAL TOXIN by Vibrant Wellness

The Total Tox Burden test is a comprehensive urine-based screening that measures your body’s exposure to three major toxin categories: heavy metals, environmental chemicals, and mold toxins (mycotoxins). Chronic toxin exposure can contribute to fatigue, hormone imbalances, immune dysfunction, neurological symptoms, and more. This test helps identify hidden toxic burdens that may be interfering with your health and healing—providing essential insight for designing a personalized detoxification and recovery plan.

7. ZOOMER by Vibrant Wellness

The Vibrant Wellness Zoomer series offers highly sensitive blood tests that screen for immune reactions to specific foods, toxins, pathogens, and environmental triggers. These microarray panels help detect both early-stage and advanced sensitivities, intolerances, and autoimmunity markers. Whether you're dealing with unexplained symptoms, chronic inflammation, or gut issues, Zoomer panels—such as Wheat Zoomer, Gut Zoomer, Dairy Zoomer, and more—provide a deep, personalized look at how your body is reacting to everyday exposures. These insights help guide targeted healing through diet, lifestyle, and therapeutic support.

8. HTMA - Hair Tissue Mineral Analysis

HTMA is a non-invasive test that measures the levels of key minerals and toxic metals stored in the hair. Because mineral imbalances and heavy metal toxicity can deeply impact energy, hormone health, nervous system function, and detoxification, HTMA offers valuable insight into your body’s long-term biochemical patterns. This test helps uncover hidden stress, metabolic dysfunction, and nutrient deficiencies—guiding personalized nutrition and lifestyle strategies to support whole-body balance.
