What are biologic medications actually doing—and what can understanding their targets teach us about autoimmunity and chronic inflammation? In Episode 91, Dr. Taylor Krick breaks down the mechanisms behind familiar medications like Humira, Remicade, Enbrel, Dupixent, Bimzelx, and Skyrizi, along with targeted synthetic medications such as Rinvoq and Xeljanz. These names may be familiar from commercials or conversations with your healthcare team, but the immune signals they target can feel like an overwhelming alphabet soup. This episode makes those signals easier to understand. Dr. Taylor explains how inflammatory messengers communicate, how different medications interrupt that communication, and why understanding the targeted pathway can help you understand what might be going on in YOUR body, and what else you can do about it.  Throughout the conversation, he connects these mechanisms to joint, gut, skin, sinus, and airway inflammation, sharing examples from his practice and his personal experience with nasal polyps and airway symptoms. In this episode, Dr. Taylor explores: • Biologics versus targeted synthetic medications: What distinguishes these categories, and why JAK inhibitors are technically different from biologic drugs. • TNF-alpha and inflammatory feedback loops: The pathway targeted by Humira, Remicade, and Enbrel, and how inflammation can become a cycle that keeps reinforcing itself. • Dupixent and type 2 inflammation: A closer look at IL-4 and IL-13 signaling, with discussions of asthma, eczema, nasal polyps, and eosinophilic esophagitis. • Mast cells and eosinophils: How different immune cells contribute to inflammatory responses—and why the type of inflammation matters. • JAK/STAT signaling: An approachable explanation of the communication happening inside cells and how medications such as Rinvoq and Xeljanz target it. • Th17 cells, IL-17, and IL-23: The pathways discussed in connection with Bimzelx, Skyrizi, and Tremfya, and the balance between protective immune responses and persistent inflammation. • Supplements and overlapping immune biology: A discussion of curcumin, resveratrol, omega-3 fatty acids, quercetin, luteolin, perilla, vitamin D, and butyrate, and the mechanisms they have been shown to influence. • The bigger picture: Why gut health, food triggers, environmental exposures, sleep, stress, and other individual factors remain part of the conversation regardless of medication. One central theme runs through the episode: understanding a medication’s target gives us another way to think about what might be keeping an inflammatory response active. Dr. Taylor encourages listeners to move beyond searching for a single supplement and consider the broader, individualized picture of their health. Whether you’re living with an autoimmune diagnosis, navigating complex symptoms, or simply curious about how the immune system works, this episode offers a clearer framework for understanding the conversation.

Can the foods we eat influence mood, focus, impulsivity, anxiety, and behavior? In this follow-up to the gut-brain connection episode, Dr. Taylor Krick explores how food communicates with the brain through the microbiome, immune system, blood sugar, neurotransmitters, and gut-brain axis. Dr. Taylor breaks down several common dietary triggers that may contribute to behavioral or neurological changes in susceptible children and adults, including gluten, dairy, sugar, synthetic food dyes, artificial sweeteners, MSG, and other ultra-processed food additives. In this episode, you’ll learn: • Why behavior can sometimes be an outward expression of what is happening internally • How genetics and the microbiome influence individual reactions to food • The potential connections between gluten, dairy, inflammation, and opioid-like peptides • How sugar may affect blood sugar, dopamine, and reward pathways • Why food dyes, aspartame, MSG, and excitatory signaling deserve attention • How a short-term elimination approach may help reveal individual triggers • Why supporting the gut may also improve clarity, focus, mood, sleep, and executive functioning Food is not the only factor influencing behavior—but it may be an important and often overlooked piece of the puzzle. This episode offers a practical, root-cause perspective for parents and adults who want to better understand the relationship between food, the gut, the brain, and everyday behavior. This episode is for educational purposes only and is not intended to diagnose, treat, or replace individualized medical care.

Can poor gut health contribute to anxiety, depression, brain fog, OCD, insomnia, neurological symptoms, or an overactive stress response?  SHORT ANSWER - - YES!!!! In this episode of The Autoimmune Doc Podcast, Dr. Taylor explains the gut-brain connection, the enteric nervous system, the vagus nerve, psychobiotics, and why a “gut on fire” can lead to a “brain on fire.” The vagus nerve is often described as the communication highway connecting the digestive system and the brain—but stimulating the vagus nerve is only one part of the picture. Your gut microbiome, intestinal lining, immune system, mast cells, hormones, bacterial metabolites, and neurotransmitters are continually sending signals along the gut-brain axis. Dr. Krick breaks down how gut dysbiosis, leaky gut, infections, bacterial or yeast overgrowth, toxins, stress, poor sleep, inflammatory foods, and other triggers may contribute to enteric neuroinflammation and changes in brain function. He also explains how gut bacteria influence important neurotransmitters such as GABA, serotonin, dopamine, and acetylcholine. In this episode, you’ll discover: • What the enteric nervous system is and why it is called the “second brain” • How the microbiome communicates with the nervous system • Why vagus-nerve stimulation may help—but may not address the root problem • How gut inflammation may influence anxiety, depression, brain fog, OCD, sleep, mood, and stress resilience • The connection between intestinal permeability, leaky gut, and neuroinflammation • How mast cells and histamine interact with enteric nerves • What psychobiotics are and how specific probiotics may influence mental health • How gut bacteria help regulate GABA, serotonin, and other neurotransmitters • The roles of prebiotics, probiotics, postbiotics, fiber, and short-chain fatty acids such as butyrate • Why a standard low-dose probiotic may not be enough to change the microbiome • Why some people need to “pull the weeds” before they “plant the seeds” • How functional stool testing and organic acids testing may guide individualized gut support • Why both symptom improvement and objective laboratory changes matter Dr. Taylor also discusses emerging research examining the gut’s possible role in neurodegenerative conditions, including Parkinson’s disease and Alzheimer’s disease. Rather than treating the brain as though it functions in isolation, this episode explores how closely neurological, immune, hormonal, and digestive mechanisms are connected.

Many people think functional medicine is simply taking supplements like magnesium, vitamin D, fish oil, or probiotics.  In this episode, Dr. Taylor Krick explains why successful healing is far more complex—and far more effective—than simply choosing the "right" supplement. Drawing from over a decade of clinical experience helping people with autoimmune diseases, chronic illnesses, and complex mystery symptoms, Dr. Taylor breaks down how functional medicine practitioners use supplements as tools to support healing, rather than as standalone solutions. You'll learn why understanding mechanisms matters more than memorizing products, how experienced practitioners build step-by-step protocols, the importance of identifying root causes, and why lab testing, timelines, dosage strategies, and patient mindset all play critical roles in recovery. Dr. Taylor also shares insights from some of the most influential educators and researchers in functional medicine and explains how concepts such as inflammation, gut health, detoxification, histamine, immune regulation, mitochondrial function, and nutrient deficiencies fit into a comprehensive healing strategy. Whether you're dealing with autoimmunity, chronic inflammation, fatigue, brain fog, digestive issues, or simply want to better understand how functional medicine works, this episode offers a behind-the-scenes look at the philosophy and process of supporting the body's ability to heal.

Fertility challenges are becoming increasingly common, but what if the conversation needs to go beyond hormone treatments and fertility clinics? In this episode of The Autoimmune Doc Podcast, Dr. Taylor Krick and Ryan Ayala explore the growing fertility crisis and the underlying mechanisms that may be contributing to infertility, recurrent miscarriages, and pregnancy complications. Rather than focusing solely on fertility treatments, Dr. Krick discusses how optimizing overall health can improve the body's natural ability to conceive and maintain a healthy pregnancy. Topics include the impact of environmental toxins, plastics, pesticides, personal care products, air quality, gut health, detoxification pathways, mitochondrial function, nutrient deficiencies, thyroid health, MTHFR, progesterone, and the role of functional medicine in uncovering hidden barriers to fertility. Whether you're actively trying to conceive, supporting a healthy pregnancy, or simply interested in understanding the factors affecting reproductive health today, this episode offers practical insights and a root-cause perspective on one of the most important health challenges facing modern families. Key Takeaways: • Why fertility rates are declining worldwide • The connection between toxins and reproductive health • How nutrient deficiencies can impact fertility • The role of gut health and detoxification pathways • Understanding MTHFR, methylation, and mitochondrial health • Why optimizing overall health often improves fertility outcomes • Practical steps to support fertility naturally As always, Dr. Krick breaks down complex science into easy-to-understand concepts that empower you to take control of your health.

In this episode of The Autoimmune Doc Podcast, Dr. Taylor Krick is joined by Mickey Trescott MSc, author of The New Autoimmune Protocol and one of the leading voices behind the Autoimmune Protocol, also known as the AIP diet or Autoimmune Paleo. If you have an autoimmune disease, Hashimoto’s, celiac disease, inflammatory bowel disease, Crohn’s disease, ulcerative colitis, psoriasis, rheumatoid arthritis, chronic inflammation, food sensitivities, leaky gut, brain fog, fatigue, joint pain, or unexplained symptoms, this episode will help you better understand how food can influence the immune system. Dr. Taylor Krick and Mickey discuss why AIP is not just a 30-day elimination diet, but a structured healing process designed to help calm immune system overactivation, support gut health, improve nutrient density, and identify personalized food triggers. They also talk about the updated version of AIP, including Core AIP, Modified AIP, the transition phase, the elimination phase, and the reintroduction process. Mickey shares how the protocol has evolved over the last decade and how new research is supporting its use in autoimmune conditions like inflammatory bowel disease and Hashimoto’s thyroiditis. This episode is a great resource for anyone trying to understand the root causes of autoimmune symptoms and how diet, food sensitivities, gut inflammation, immune regulation, nutrient density, and lifestyle all connect.
