Nutritional, Hormone & Food Allergy Testing & Counseling

Personalized insights to restore balance, energy, and wellbeing

A Deeper Look Into Your Health

If you’re feeling off but haven’t found answers through traditional testing, it’s time to go deeper. Our advanced diagnostic approach helps uncover the root causes of imbalance. Whether it’s nutrient depletion, hormonal fluctuations, food sensitivities, or metabolic blocks that are making weight loss feel impossible. Through in-depth testing and expert clinical nutrition guidance, we help you understand what’s really going on in your body — and how to restore balance naturally.

Why Choose Functional Testing at Immunity Health Spa?

At Immunity Health Spa, we go beyond routine lab work. Our clinical nutritionist, Katie Gravante, CL.N., CNC, specializes in advanced, data-driven testing that provides a clearer picture of how your body is functioning — not just where you fall on a general reference range. We offer solutions for those who’ve gone the traditional route and still aren’t feeling their best. Whether you’re navigating unexplained symptoms, chronic fatigue, or long-term health goals, our approach is thorough, personalized, and empowering.

What We Test For:

Micronutrient & Vitamin Deficiencies Our intracellular testing looks at 33 key nutrients across a 4–6 month window, identifying deficiencies that may affect metabolism, brain function, immunity, and more.
Hormone Balance & Adrenal Function We evaluate cortisol, estrogen, progesterone, testosterone, and thyroid function to identify hormonal imbalances that may be affecting mood, metabolism, or weight.
Gut Health & Digestive Function We assess the microbiome, intestinal inflammation, and digestive enzyme activity to understand how your gut is impacting energy, skin, and immune function.
Food Sensitivities & Immune Responses By identifying low-grade inflammatory responses to foods, we can help reduce symptoms like bloating, fatigue, or skin issues — and support a more balanced immune response.
GLP-1 Assisted Weight Loss Program For clients struggling with stubborn weight, insulin resistance, or hormonal shifts, our GLP-1 program offers medically supervised peptide therapy integrated with your test results and nutritional needs.
Bioidentical Hormone Replacement Therapy If your test results show hormonal deficiencies, we offer natural hormone-balancing solutions tailored to your physiology and long-term wellness.
