Every journey starts with a free 30-minute discovery session. From there we pick the path that fits — a focused review, a 3-month protocol, or an ongoing partnership.
Start here · Free · 30 min
A 30-minute conversation to discuss your health history, current concerns, and wellness goals. Introduces how functional diagnostics and personalized nutrition can help — no commitment, no obligation.
An introduction to functional health for general optimization and mineral-balancing concerns like fatigue, mood swings, and energy. Includes HTMA testing, recent blood-work review, and a personalized mineral, lifestyle, and dietary protocol.
Free Initial Discovery Session included
Comprehensive functional lab testing selected from your Initial Discovery findings and tailored to your biochemistry. Includes bi-weekly check-ins and a custom-designed protocol with step-by-step guidance built specifically around your history, symptoms, and results.
Free Initial Discovery Session included
A personalized approach for chronic or complex health concerns. Ongoing testing and protocol adjustments identify root stressors and shape the plan as your body responds.
Free Initial Discovery Session included
A stool test which provides a comprehensive analysis of your gut health, identifying microbiome imbalances, pathogens, inflammation, and digestive function markers.
Analyzes the mineral content of your hair to uncover imbalances that may be affecting your metabolism, stress response, and overall health. Provides insight into nutrient status in the body, adrenal function, thyroid function, calcium and copper regulation and heavy metal excretion.
A urine-based test that measures hormone levels and metabolites, offering a detailed picture of your stress hormone balance and stress response, sex hormone production and metabolism, hormone metabolic pathways and several organic acid markers looking at general health, B12, neurotransmitter, inflammation status and common hormone disruptors that may be interfering with hormonal function/production.
A blood chemistry panel that looks for markers of altered brain chemistry and inflammation to help address neuroinflammatory conditions.
The most comprehensive toxin test available, screening for environmental toxins including mold mycotoxins, heavy metals, chemical and pesticide exposure to assess toxic burden on the body.
A urine test that provides deep insights into yeast/fungal overgrowth and other pathogenic bacterial metabolites, metabolic function, neurotransmitter function, nutrient deficiencies, detoxification, and gut health.
Functional blood chemistry panels offer a foundational assessment of overall health and allow for early detection of imbalances before they develop into chronic disease.
Comprehensive IgG, IgA, and/or IgE blood spot testing to identify foods triggering inflammation in your body. These critical assessments reveal hidden food reactions that may be contributing to your chronic symptoms, allowing us to create a targeted healing protocol based on your unique immune responses.
Genetic-based testing that evaluates how your body processes nutrients, metabolizes toxins, and responds to dietary and lifestyle factors. It helps tailor nutrition, detoxification support, and supplementation strategies based on your unique genetic blueprint to optimize health outcomes.
Comprehensive autoimmune testing that can be run for systemic or neuro-immune markers. Test options are selected based on individual need and can reveal biochemical imbalances and silent inflammation long before full-blown disease appears.
Pinpoint the chemical messengers driving your mood, focus, and stress response. A Neurotransmitter Panel measures key brain-signaling metabolites to uncover imbalances that may underlie anxiety, low energy, sleep issues, or hormonal symptoms — providing clear, personalized data to guide targeted nutrition and lifestyle support.
Comprehensive biotoxin illness assessment using Dr. Shoemaker's established laboratory panel. Evaluates inflammatory markers, immune dysfunction, and metabolic disruption caused by exposure to mold toxins, Lyme/co-infections, actinomycetes, cyanobacteria, dinoflagellates, and other biotoxins. Essential for identifying and monitoring treatment progress in people with chronic fatigue, brain fog, respiratory issues, and multi-system symptoms.
Comprehensive screening for Borrelia (Lyme disease), Babesia, and Bartonella using advanced molecular diagnostics and antibody detection. These tick-borne infections often present with overlapping symptoms including chronic fatigue, brain fog, joint pain, and neurological symptoms that can mimic other conditions. Testing identifies active infections and immune system responses to guide targeted treatment protocols.
Every client is a partner in their wellness journey. Here is how the work typically unfolds.
I'm Katka Gazdik — MSc Neuroscience, BSc Cell & Molecular Biology, and a Functional Diagnostic Nutrition Practitioner. My work lives at the intersection of advanced biochemistry and compassionate, personalized care.
My own health story led me from academic science into the world of complex chronic illness, where "normal" labs rarely tell the whole truth. Now I use my training to untangle the biochemical patterns behind symptoms — helping clients finally understand why they feel the way they do, and what we can do about it.
If you've been told "everything looks fine" but you still don't feel like yourself, you're in the right place.Read the full story →

"After a long and exhausting journey trying to find answers for his PANS symptoms, we finally found someone who truly listened. The changes we've seen in my son are nothing short of incredible — he's been able to completely stop his ADHD medication, something I never imagined possible."
"I've been chronically ill for the past 11 years. Since beginning to work with Katka, I've made more progress and uncovered more answers about my health than I had on my own over the past decade of painstaking self-experimentation and research."
"As a last resort measure, I consulted with Kat. About three months into the protocol my issue basically entirely resolved — I couldn't believe it. She knows the precise cellular mechanisms that underlie her protocols, and can explain them to you."
"After getting crazy sick without explanation and getting zero help from conventional doctors I was referred to Katka who did an amazing job figuring out what was going on with my health on a cellular level and putting together an amazing eradication plan to clean out my body and get my energy and health back! I highly recommend Katka at Katalyst Health — she knows what she's talking about!!!"
"I am a 77 year old, and over the past two years I started to feel increasingly lethargic and was gaining weight. All my life I have been active, adventurous, and full of ideas, but recently I found myself dragging through the days — feeling bloated, tired, and sleeping far too much. Then Katka Gazdik ran comprehensive tests to determine what my body was lacking in vitamins and minerals, as well as identifying my food sensitivities. Following her expert advice and personal guidance, my energy levels and digestion improved noticeably within three months. After continuing with the prescribed diet and protocol, I can honestly say I feel great again — energetic, clear-headed, and back to my old self. I am deeply grateful for Katka's knowledge, professionalism, and caring approach. I highly recommend Katalyst Health to anyone looking to restore their vitality and well-being."
"I can't recommend Katka enough! After my knee surgery (MACI + TTO), I was stuck in a frustrating cycle of pain and inflammation that just wouldn't quit despite months of physical therapy. Katka ran comprehensive testing — food sensitivity, gut biome, bloodwork, and genetics — and created a personalized plan with diet changes and custom supplements. Within 3 weeks, my knee pain and inflammation were GONE. I was honestly shocked. All that physio with minimal results, and then I remove some trigger foods and add the right supplements, and the pain just disappears? The bonus? I've lost weight, have way more energy, and my family says I'm way less grumpy. 😊 Katka's approach is thorough, science-based, and actually works. If you're dealing with stubborn issues that conventional approaches aren't solving, give her a call. She's the real deal."
