Functional Nutrition & GI Mapping in Costa Mesa and Orange County
At Amity Health Direct Primary Care (DPC) in Costa Mesa, CA, we take a deeper, root-cause approach to health through Functional Nutrition and Functional Medicine. Our goal is to help patients in Orange County uncover what’s truly driving their symptoms—whether it’s gut imbalance, inflammation, hormone disruption, or nutrient deficiencies—and guide them toward lasting wellness through science-backed nutrition and lifestyle strategies.
What Is Functional Nutrition?
Functional Nutrition looks at how food interacts with your body’s unique biochemistry. Instead of managing symptoms, it identifies the underlying dysfunctions that cause fatigue, digestive issues, and chronic inflammation.
By combining nutrition science, functional lab testing, and personalized care, we design plans that restore balance, optimize digestion, and promote healing from the inside out.
At Amity Health DPC, we focus on:
GI Mapping & Stool Testing: Using advanced GI-MAP testing, we analyze the gut microbiome, enzyme levels, inflammation markers, and pathogens to uncover the root of digestive and immune issues.
Autoimmune Protocol (AIP): A targeted nutrition plan designed to reduce inflammation and calm the immune system for those struggling with autoimmune diseases like Hashimoto’s, rheumatoid arthritis, or celiac disease.
Leaky Gut Repair: Restoring gut lining integrity to reduce food sensitivities and improve nutrient absorption.
Hormone & Thyroid Balancing: Addressing adrenal fatigue, thyroid imbalances, and cortisol regulation through nutrition and lifestyle support.
Detoxification & Liver Support: Helping your body eliminate toxins safely and efficiently with nutrient-rich foods and supplements.
Adrenal & Stress Recovery: Supporting optimal energy levels, sleep, and mood through root-cause analysis and lifestyle optimization.

Focused Expertise in Gut Health and Functional Medicine
Many patients come to us with bloating, abdominal pain, IBS, or irregular digestion that traditional testing can’t explain. Our functional GI testing and nutrition-based interventions reveal what’s hidden beneath the surface—from bacterial imbalances to enzyme deficiencies—and guide you toward effective, natural solutions.
Our goal: to help you eat, digest, and thrive with optimal gut and immune health.
Honest, Transparent, and Science-Based Care
We are committed to integrity and transparency. Functional medicine is powerful, but not a one-size-fits-all approach. We’ll always set realistic expectations and guide you with honesty, evidence, and empathy.
Our Philosophy and Mission
Founded by Dr. Tsay, Amity Health DPC is rooted in the belief that healthcare should be personalized, holistic, and empowering. Too many patients experience digestive discomfort, hormonal imbalances, or chronic fatigue without clear answers. Our functional nutrition and medicine services aim to change that—helping you understand your body, address the root causes, and restore lasting health.
