    The Supplement That Makes My Brain 2 Steps Ahead of Everyone

    In this Supplement Ingredients episode, Nurse Doza breaks down phosphatidylcholine—one of his all-time favorite supplements for your liver and brain. He explains why medications and aging deplete your choline, how phosphatidylcholine delivers fast energy, focus, and mental clarity without stimulants or a crash, and why he finally landed on BodyBio after years of testing. If liver issues or cognitive decline are on your radar, this one's a must-listen. FEATURED PARTNER: BODYBIO BodyBio Phosphatidylcholine (PC) delivers clean, bioavailable phospholipids that rebuild your cell membranes—supporting the liver and brain function discussed in this episode—with a noticeable "crisp" clarity you can feel in about an hour, no jitters and no crash. 👉 Get BodyBio PC here: https://partners.bodybio.com/DOZA 👉 Use code DOZA at checkout 5 KEY TAKEWAYS Phosphatidylcholine feeds your brain AND your liver. Your body naturally stores it in both organs, where it supports cell membranes, choline status, and acetylcholine—the neurotransmitter tied to focus and memory. It's not a stimulant. You get energy, focus, and clarity without jitteriness or a crash, because phosphatidylcholine is something your body already makes and uses. Medications and aging deplete your choline. Over time you lose stores, which is why supplementing with phosphatidylcholine becomes increasingly important for liver and cognitive health. Quality and source matter. After years of testing different types, Doza landed on BodyBio for its noticeable, "crisp" clarity you can actually feel within an hour or two. Simple protocol. Just two BodyBio PC in the morning on an empty stomach—no complicated stacking required.

    Why Your Hormones Are A Mess And What To Do Bout It

    Discover why hormones are off and what's really driving the imbalance. In this episode, we break down five root causes — from gut dysfunction and disrupted sleep to chronic stress, appetite dysregulation, and omega-3 deficiency — and walk through what you can actually do to fix it. FEATURED PRODUCT Berberine is a powerful botanical compound that acts as a natural GLP-1 supporter — the same metabolic pathway targeted by medications like Ozempic — helping regulate blood sugar, reduce insulin resistance, and restore appetite signaling from the gut. Since metabolic hormones like insulin and leptin are the first to derail your entire hormone cascade, Berberine directly addresses one of the deepest root causes discussed in this episode. It also supports gut microbiome diversity, making it a foundational tool for anyone working to reclaim hormonal balance naturally. 👉 Get Berberine here: https://mswnutrition.com/products/berberine 5 KEY TAKEAWAYS Your gut microbiome directly regulates your hormones. A specialized subset called the estrobolome — and an enzyme called beta-glucuronidase — controls how estrogen is metabolized and cleared.  Poor sleep is one of the most overlooked hormone disruptors. Deep sleep triggers melatonin and human growth hormone — both of which reset sex hormones, lower cortisol, reduce insulin, and regulate LH and FSH signaling from the brain. Without quality sleep, the entire endocrine cascade is compromised. Chronic stress drives a hormone cascade that makes everything worse. High cortisol suppresses melatonin, triggers late-night cravings, raises insulin and leptin, and disrupts dopamine — all before it ever touches your estrogen or testosterone levels. Metabolic hormones fail first — and take sex hormones down with them. Insulin, leptin, cortisol, GLP-1, and ghrelin are the first hormones to go off track. Once they're dysregulated, estrogen, testosterone, and thyroid function follow. Addressing only sex hormones without fixing the metabolic layer is why hormone replacement often fails to deliver results. Omega-3 DHA is non-negotiable for hormone health. DHA supports testosterone and estrogen production, acts as a prebiotic for the gut microbiome, reduces inflammation (including painful periods), and cannot be obtained in therapeutic amounts through diet alone. Getting enough requires supplementation.

    Your Old Infection Might Be Causing Your Current Autoimmune Disorder

    Discover 5 key autoimmune triggers hiding in your past. From COVID and herpes simplex to staph, Epstein-Barr, and strep infections, Nurse Doza breaks down how past infections can reprogram your immune system to attack your own tissue — and what gut health has to do with it all. Gut (L-Glutamine) by MSW Nutrition Gut, featuring 4 grams of pure L-Glutamine per scoop, is the primary fuel source for the cells that line your intestinal wall. When past infections, antibiotics, or chronic stress compromise your gut barrier, your immune system loses its most important line of defense — creating the conditions where autoimmune triggers thrive. Gut helps repair the gut lining, reduce digestive inflammation, and support the immune cells that depend on a healthy gut to function properly. Whether you’re managing an existing autoimmune disorder or working to prevent one, healing your gut is where it starts. 👉 Get Gut here: https://mswnutrition.com/products/gut 5 KEY TAKEAWAYS Past infections are one of the most underrecognized autoimmune triggers.  COVID, herpes simplex, staph, Epstein-Barr, and strep have all been scientifically linked to the development of autoimmune disorders — often years after the original infection. Molecular mimicry is the hidden mechanism.  Some infections look so similar to your own tissue that your immune system gets confused and begins attacking you. This is an active and growing area of clinical research. You can have multiple autoimmune disorders simultaneously.  Most conventional doctors don’t connect the dots. Conditions like POTS, Ehlers-Danlos, PANDAS, and lupus can all be present at once — often rooted in overlapping infection history. The gut is ground zero for immune regulation.  A disrupted gut microbiome — caused by antibiotics, poor diet, and chronic infections — is a major driver of autoimmune disease. Gut dysbiosis doesn’t just cause digestive problems; it rewires your immune response. Supporting the gut lining is one of the most foundational steps you can take.  L-Glutamine patches the holes in a compromised gut lining, calms inflammation, and feeds the immune cells that live in your gut. Combined with Vitamin D, it’s a simple starting protocol for anyone dealing with autoimmune issues.

    Berberine 101: Energy, Digestion & Weight — One Capsule

    Think energy, digestion, and weight. In this episode, Nurse Doza breaks down berberine — the metabolism-supporting supplement that helps regulate blood sugar, support a healthy insulin response, and improve cholesterol (LDL, HDL, total). Discover why MSW Nutrition’s Berberine Plus is 5x more absorbable in the gut, how to dose it morning and night, and why it works at the level of your gut microbiome. The berberine supplement your metabolism has been waiting for. Featured Partner: MSW Nutrition — Berberine Plus MSW Nutrition’s Berberine Plus delivers dihydroberberine (DHB) — the bioactive, highly absorbable form of berberine sourced from Berberis aristata — so you get berberine’s full metabolic benefits at a fraction of the dose, without the gut upset that comes from mega-dosing standard berberine. That enhanced absorption is exactly why it’s the berberine supplement Nurse Doza reaches for to support blood sugar, digestion, and weight — as discussed in this episode. 👉 Get Berberine Plus here: Biggest sale of the year — Buy 2, Get 1 Free at: https://berberine.mswnurition.com 5 Key Takeaways Berberine works with your blood sugar, not against it. You have insulin receptors throughout your body, and you do need some blood sugar — just not too much. Berberine helps lower blood glucose and support a healthy insulin response primarily when levels run high, rather than forcing them down indiscriminately. It’s not just blood sugar — it’s your cholesterol too. Beyond glucose and insulin, berberine has been shown to support healthier lipid numbers, including LDL, total cholesterol, and triglycerides — a major reason it’s a metabolism all-rounder. Absorption is everything — and DHB is the upgrade. Standard berberine is notoriously hard to absorb. Berberine Plus uses dihydroberberine, roughly 5x more absorbable in the gut, so a smaller dose delivers comparable effects with less digestive distress. Your gut microbiome is where the magic happens. Most berberine stays in the intestinal lumen and works at a cellular level inside the gut — reshaping the microbiome and its metabolites, which is a key part of how it improves glucose and lipid metabolism. Timing matters: think morning and night. A morning dose (with or without food) supports daytime blood sugar; an optional second evening dose supports overnight digestion and metabolic recovery while you sleep. Resources “Absorption Kinetics of Berberine and Dihydroberberine and Their Impact on Glycemia” (Nutrients, 2022) — Randomized, controlled, crossover pilot trial showing low-dose dihydroberberine produced significantly greater plasma berberine than a 500 mg dose of standard berberine, confirming DHB’s superior oral absorption. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8746601/ “Glucose-Lowering Effect of Berberine on Type 2 Diabetes: A Systematic Review and Meta-Analysis” (Frontiers in Pharmacology, 2022) — Meta-analysis of 37 randomized controlled trials (3,048 patients) finding berberine significantly reduces fasting plasma glucose, HbA1c, and 2-hour postprandial glucose without causing hypoglycemia. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9709280/ “Effects of Administering Berberine Alone or in Combination on Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis” (2024) — Analysis of 50 studies (4,150 participants) showing berberine alone significantly reduced fasting glucose, postprandial glucose, LDL cholesterol, total cholesterol, and triglycerides. https://pubmed.ncbi.nlm.nih.gov/39640489/ “The Effect of Berberine Supplementation on Glycemic Control and Inflammatory Biomarkers in Metabolic Disorders: An Umbrella Meta-Analysis” (2023) — Umbrella review pooling multiple meta-analyses, demonstrating berberine improves fasting blood glucose, HbA1c, insulin, and HOMA-IR while lowering inflammatory markers (IL-6, TNF-α, CRP). https://pubmed.ncbi.nlm.nih.gov/38016844/ “Berberine–Microbiota Interplay: Orchestrating Gut Health” (Frontiers in Microbiology, 2023) — Review explaining how berberine, which largely remains in the gut, works by modulating microbiota composition and short-chain fatty acid production to drive its metabolic benefits. https://pmc.ncbi.nlm.nih.gov/articles/PMC10733463/ Connect with Nurse Doza 🔗 JOIN MY SCHOOL for FREE: https://community.schoolofdoza.com/c/start-here YouTube: https://www.youtube.com/channel/UCwcKyagDi468WscAOWM5VHA Instagram: https://www.instagram.com/nursedoza/ Website: http://www.nursedoza.com/ LinkedIn: https://www.linkedin.com/in/jonathan-mendoza-dc-aprn-np-c-0609a038/ TikTok: https://www.tiktok.com/@nursedoza Twitter: https://twitter.com/nursedoza

    All About Serotonin

    Serotonin does far more than regulate mood — 90% of it is made in your gut, not your brain. In this episode, Nurse Doza breaks down exactly what serotonin does, why so many people are unknowingly depleted, and how to naturally restore levels through gut health, B vitamins, sunlight, and targeted supplementation.   FEATURED PRODUCT Bliss by MSW Nutrition Serotonin production depends on methylation — and if your methylation pathways are sluggish, you can be doing everything right and still come up short. Bliss is a lemon-flavored sublingual powder featuring TMG (trimethylglycine), a powerful methyl donor that directly supports the methylation reactions your body needs to synthesize serotonin and dopamine. As discussed in this episode, the MTHFR gene, B vitamins, and SAMe are all essential cofactors in serotonin production — and Bliss is formulated to address exactly that gap. Just place it on your tongue and let it absorb in seconds. One serving a day is all it takes. 👉 Get Bliss here: https://mswnutrition.com/products/bliss   JOIN THE SCHOOL OF DOZA If this episode opened your eyes to the gut-serotonin connection, imagine going even deeper. Inside the School of Doza, you'll find a full MTHFR course that explains exactly how your genetics affect your ability to produce serotonin, dopamine, and other neurotransmitters — and what you can do about it. Whether you're dealing with anxiety, mood swings, poor sleep, or brain fog, you're not alone in that journey. Our community is full of people working on the same root causes, and every Wednesday we host a live group consult (Ask Me Anything session) where you can bring your questions and get real answers — just like a private consultation, but with a room full of people who get it. 👉 Start your free trial: https://community.schoolofdoza.com/c/start-here     5 KEY TAKEAWAYS 90% of serotonin is made in your gut — not your brain. If your gut health is compromised, your serotonin production is compromised. Depression, anxiety, and mood disorders often have a digestive root cause that standard care rarely addresses. Gut dysbiosis — from antibiotics, processed foods, dairy, and poor diet — disrupts the bacterial enzymes and cofactors (like 5-HTP and TPH1) that your microbiome uses to synthesize serotonin. Healing the gut is foundational to healing the mood. Serotonin converts to melatonin at night. If you're low on serotonin, you're also likely low on melatonin — which explains why gut problems, depression, and insomnia so often travel together. B vitamins — especially B6 (P5P), B9 (methylfolate), and B12 — are essential cofactors for serotonin synthesis. MTHFR gene variants impair the methylation pathway that drives this process, making methylated B vitamins and methyl donors like SAMe critical for many people. Sunlight and exercise are among the most powerful natural serotonin activators. Combined with gut repair, B vitamin support, and targeted supplementation like Bliss, these lifestyle inputs can meaningfully shift your serotonin baseline without relying solely on medication.   TIMESTAMPS 00:00 – START – Welcome and episode overview   02:00 – Serotonin 101: what it is and why 90% is made in your gut   03:48 – School of Doza spotlight: the MTHFR course   06:46 – Serotonin and depression: what we've gotten wrong   09:08 – The gut microbiome: good bacteria, bad bacteria, and neurotransmitter production   11:31 – Antibiotics, 5-HTP, and how your gut makes serotonin   13:56 – Food, dairy, and diet choices that wreck your gut microbiome   16:23 – Why SSRIs alone aren't enough — and what to do instead   17:28 – Serotonin converts to melatonin: the gut-sleep connection   20:00 – The insomnia-depression-gut triangle   21:05 – B vitamins and methylation: essential cofactors for serotonin   23:18 – MTHFR, the liver, SAMe, and Bliss by MSW Nutrition   25:30 – The 5th factor: sunlight, exercise, and a full serotonin reset protocol   28:21 – Bliss — sublingual methylation support for serotonin and dopamine   RESOURCES Serotonin Overview — Cleveland Clinic — Comprehensive guide to what serotonin is, what it does, and how it affects the body. https://my.clevelandclinic.org/health/articles/22572-serotonin   Gut Microbiota and Serotonin Synthesis — ScienceDirect — Peer-reviewed research on how gut bacteria directly influence serotonin production, kynurenine pathways, bile acids, and vitamin cofactors. https://www.sciencedirect.com/science/article/pii/S2950194626000142   Serotonin to Melatonin Conversion — PMC/NIH — Research on the biochemical pathway by which serotonin is converted into melatonin, including the role of SAMe as a cofactor. https://pmc.ncbi.nlm.nih.gov/articles/PMC8659113/   B Vitamins and Neurotransmitter Synthesis — PMC/NIH — Research on how B6, B9 (folate), and B12 act as rate-limiting cofactors in serotonin, dopamine, GABA, and melatonin production. https://pmc.ncbi.nlm.nih.gov/articles/PMC4772032/   🔗 Connect with Nurse Doza JOIN MY SCHOOL for FREE: https://community.schoolofdoza.com/c/start-here YouTube: https://www.youtube.com/channel/UCwcKyagDi468WscAOWM5VHA Instagram: https://www.instagram.com/nursedoza/ Website: http://www.nursedoza.com/ LinkedIn: https://www.linkedin.com/in/jonathan-mendoza-dc-aprn-np-c-0609a038/ TikTok: https://www.tiktok.com/@nursedoza Twitter: https://twitter.com/nursedoza

    5 Things Silently Inflaming Your Body!

    Chronic inflammation is silently driving some of the most common diseases today — and most people have no idea it's happening. In this episode, Nurse Doza breaks down five hidden triggers: poor sleep, refined grains, low vitamin D, omega-3 deficiency, and digestive issues — and exactly what you can start doing about each one today. FEATURED PRODUCT Liver Boost – MSW Nutrition Chronic inflammation doesn't just live in your joints or your gut — your liver is at the center of it all. The liver filters inflammatory byproducts, processes environmental toxins, manages hormones, and supports fat digestion. When it's overburdened, your inflammatory load goes up. Liver Boost from MSW Nutrition is formulated with N-acetyl-L-cysteine (NAC), milk thistle, and selenium to support liver detoxification, protect your antioxidant defenses, and ease the total burden your body is carrying — making it a natural complement to everything discussed in this episode. 👉 Get Liver Boost here: https://mswnutrition.com/products/liver-boost JOIN THE SCHOOL OF DOZA Chronic inflammation is personal — and figuring out what's driving yours requires more than a podcast. Inside the School of Doza, you'll find a community of people working through the same issues: sleep optimization, gut health, autoimmune conditions, lab interpretation, and more. Every Wednesday, join a live Ask Me Anything session that functions like a group consult — bring your labs, your questions, your protocols, and get real answers in real time. Your first seven days are completely free. 👉 Start your free trial: https://community.schoolofdoza.com/c/start-here 5 KEY TAKEAWAYS Poor sleep is one of the most overlooked drivers of chronic inflammation — it suppresses melatonin (a powerful antioxidant), raises inflammatory markers like IL-6, and is directly tied to heart disease, dementia, fatty liver, and weight gain. Refined grains — bread, rice, pasta, corn — damage the gut lining, creating leaky gut that allows toxins, pathogens, and inflammatory particles to enter the bloodstream and fuel systemic inflammation. Vitamin D deficiency is extremely common and directly linked to chronic inflammation, weakened immunity, heart disease, depression, and dozens of other conditions. Daily supplementation of vitamin D3 + K2 (5,000 IU) is a non-negotiable baseline. Most people are omega-3 deficient and omega-6 overloaded from seed oils (canola, corn, peanut, safflower) — this imbalance creates a pro-inflammatory environment. Eating more fatty fish or taking a quality fish oil helps correct it. Leaky gut is a root cause of systemic inflammation.

    TMG: The Mood Molecule Your Doctor Never Mentioned

    Your mood struggles might not be a mindset problem — they might be a methylation problem. In this episode, Nurse Doza breaks down the TMG supplement (trimethylglycine), how it drives serotonin and dopamine production, and why pairing it with SAMe in BLISS delivers clean energy and mood support — no caffeine, no stimulants, results in minutes. Featured Partner: MSW Nutrition — BLISS BLISS by MSW Nutrition combines two of the most underutilized mood-support compounds in functional medicine — trimethylglycine (TMG) and SAMe — in a fast-absorbing sublingual powder. Together, they fuel the methylation pathways your body needs to produce serotonin, dopamine, and sustainable energy — exactly the mechanisms Nurse Doza unpacks in this episode. No caffeine. No fillers. No stimulants. Just the two ingredients your brain chemistry has been waiting for. 👉 Get BLISS here: bliss.mswnutrition.com 5 Key Takeaways 1. TMG is a methyl donor, not a stimulant. Unlike caffeine or pre-workout compounds, trimethylglycine works by donating methyl groups to critical biochemical pathways. This directly supports the production of serotonin, dopamine, and norepinephrine — the neurotransmitters behind mood, motivation, and mental clarity. 2. The MTHFR gene affects more people than doctors realize. Variants in the MTHFR gene reduce the body’s ability to convert folate into active methylfolate, impairing neurotransmitter synthesis. Research shows 74% of treatment-resistant depression cases test positive for MTHFR polymorphism. The TMG supplement directly supports this compromised methylation pathway. 3. SAMe is one of the most clinically studied mood compounds available. A 2024 meta-analysis of 23 randomized controlled trials (N=2,234) confirmed that SAMe produced significantly greater reductions in depressive symptoms compared to placebo. TMG raises SAMe levels in the body — making the BLISS stack a powerful, evidence-backed combination. 4. Sublingual delivery accelerates results. BLISS is formulated as a sublingual powder, bypassing the digestive tract and delivering TMG and SAMe directly into the bloodstream. That’s why users can feel a difference in seconds to minutes — not hours. The absorption advantage is real. 5. This is clean energy — not stimulant energy. The energy benefit of BLISS is neurotransmitter-driven, not caffeine-driven. By supporting healthy dopamine and serotonin levels, TMG and SAMe restore the natural energy and focus that emerges when your brain chemistry is actually balanced. No crash. No dependency.
