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.

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 |

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.

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.

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. When the gut barrier is compromised, it contributes to autoimmune disorders, fatty liver, hormone imbalances, and even dementia. L-glutamine, NAC, and zinc help restore tight junction integrity and begin the healing process.

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.

Dopamine controls your motivation, focus, mood, and reward system — and most people are running low without realizing it. In this episode, Nurse Doza breaks down what dopamine actually does in the body, why deficiency is far more common than most people think, how your gut produces 50% of it, and the natural steps you can take to restore healthy levels.
FEATURED PRODUCT: BLISS
Bliss by MSW Nutrition is a lemon-flavored sublingual powder built around SAMe and TMG — two powerful methyl donors that directly support your body’s natural dopamine and serotonin production through the methylation pathway. If you’re feeling flat, foggy, or low-mood, methylation may be the missing link. One powder stick dissolved on your tongue — no water needed — and you may feel the difference within seconds to minutes. Bliss also supports glutathione production, liver health, and MTHFR function, making it one of the most targeted neurotransmitter support supplements available.
👉 Get Bliss here: https://mswnutrition.com/products/bliss
5 KEY TAKEAWAYS
Your lifestyle drives dopamine production — morning sunlight, exercise, quality sleep, music, and meditation are all proven natural dopamine boosters your body responds to every single day.
Most people are dopamine deficient — driven by overstimulation, poor sleep, gut dysfunction, and modern demands that drain the system faster than it can replenish.
50% of your dopamine is made in your gut — digestive issues like bloating, SIBO, leaky gut, or dysbiosis can directly tank your mood, focus, and motivation.
Dopamine is the engine behind addiction — when levels are chronically low or the reward system is dysregulated, the brain compulsively seeks dopamine hits from food, substances, screens, risky behavior, or work.
Key nutrients support natural dopamine synthesis — Vitamin B6, B9 (folate), iron, Vitamin C, and SAMe are essential cofactors in the dopamine production pathway and can be supported through targeted supplementation.

What if a single gene is quietly affecting your mood, energy, sleep, and focus — and most doctors never test for it? In this episode of the Longevity Series, Nurse Doza breaks down MTHFR gene support: what methylation is, why this gene matters, and how BLISS by MSW Nutrition delivers targeted sublingual support — sometimes with noticeable results the same day.
BLISS by MSW Nutrition is a sublingual powder formulated with two active ingredients specifically designed to support the MTHFR gene and the methylation cycle. For people with MTHFR variants — who may struggle with mood regulation, low energy, brain fog, and disrupted sleep — BLISS bypasses the digestive process entirely, delivering its active compounds directly into the bloodstream under the tongue for fast, efficient absorption. Nurse Doza and co-founder Baldo both have confirmed MTHFR issues and take BLISS daily — this is a supplement built from personal need, not theory. One box contains 30 packets, making it a full 30-day protocol.

5 Key Takeaways
MTHFR gene variants are far more common than most people realize. Approximately 30–40% of people carry a variant of the MTHFR gene that reduces enzyme efficiency — sometimes by as much as 70%. If you’ve ever been dismissed with “normal” labs while still feeling off, this gene may be the missing piece.
Methylation controls more of your health than you think. The methylation cycle governs neurotransmitter production, detoxification, hormone regulation, and DNA repair. When MTHFR impairs this pathway, mood, energy, digestion, and long-term health can all be affected.
Low serotonin from poor methylation can wreck your sleep. Because serotonin is the precursor to melatonin, impaired methylation can directly disrupt your sleep-wake cycle. Supporting the MTHFR pathway can help restore the serotonin–melatonin conversion your body needs for deep, restorative sleep.
Sublingual delivery changes the absorption game. Traditional capsules and powders can lose significant potency through first-pass digestion. BLISS is a sublingual powder that bypasses the GI tract entirely, entering the bloodstream directly through the oral mucosa for faster, more efficient delivery.
You can override poor genetics with the right support. Having an MTHFR variant is not a life sentence. Targeted methylation support through active-form nutrients can help compensate for reduced enzyme activity, improving neurotransmitter output and overall cellular function.

Sleep and weight gain are directly connected. Poor sleep disrupts hormones, raises blood sugar, tanks testosterone and estrogen, causes fatty liver, and wrecks your gut. If you've been doing everything right and the scale won't move, your sleep could be the missing link.
FEATURED PRODUCT
Chill by MSW Nutrition is a powdered drink mix formulated to support your body's natural calming chemistry — exactly what's needed when chronic stress and cortisol overload are stealing your sleep. Featuring GABA, L-Theanine, myo-Inositol, Taurine, and Magnesium, Chill helps balance neurotransmitters, quiet the nervous system, and promote the deep, restorative sleep your hormones, metabolism, and weight depend on — all five mechanisms discussed in this episode.

5 KEY TAKEAWAYS
Sleep deprivation activates the HPA axis, raising cortisol and suppressing melatonin
Poor sleep spikes blood sugar and insulin even without eating.
Lack of REM sleep directly lowers testosterone in men and disrupts estrogen in women.
Poor sleep causes fatty liver (MASLD/NAFLD) by disrupting insulin sensitivity, lipid metabolism, and inflammation markers like TNF-alpha, IL-6, and CRP. Melatonin — made during quality sleep — has been shown to actually prevent and reverse fatty liver progression.
Sleep deprivation damages the gut microbiome by reducing beneficial bacteria like Akkermansia and Bacteroides, breaking down the intestinal barrier, and triggering gut-brain neuroinflammation — all of which contribute to weight gain and metabolic dysfunction.

Two supplements. One morning stack. Nurse Doza breaks down why Liver Boost and Berberine Plus work better together — and how the Good Poops Protocol combines them with a gut-repair formula to support liver, gallbladder, blood sugar, and weight.
Today is the last day to save an extra 10% automatically on the full protocol.
The Good Poops Protocol is a three-supplement system designed by Nurse Doza, DC, RN, FNP-C — combining Liver Boost (16-ingredient Phase I + II liver detox support), Berberine Plus (5x more bioavailable dihydroberberine for blood sugar and digestion), and Gut (L-Glutamine formula for intestinal lining and gut flora) — into one 60-day protocol. As discussed in this episode, when you support liver function and blood sugar management simultaneously, the downstream effects on digestion, weight, and overall health can be profound — and noticeable within days.

5 Key Takeaways
Liver Boost and Berberine work better together. Taking them separately misses the synergy. Stacked together first thing in the morning on an empty stomach, they hit liver detoxification and blood sugar management simultaneously — two systems that are deeply interconnected.
Your blood sugar ends up in your liver. Every glucose spike you take in gets processed by the liver. If liver function is compromised, blood sugar regulation suffers. Supporting both at once is the smarter approach.
Timing and dosing matter. Start with one to two Liver Boost capsules in the morning on an empty stomach. Add Berberine Plus at the same time, or experiment with a dose before your largest meal. Most people notice digestive changes within days, and broader improvements within a few weeks.
The Good Poops Protocol adds the gut layer. Liver Boost and Berberine address upstream function, but the Gut formula — an L-Glutamine-based powder — repairs the intestinal lining and supports gut flora. All three systems depend on each other.
Play around with it. There's no single rigid protocol. Nurse Doza encourages listeners to experiment with meal timing, split dosing, and combinations to find what works for their specific body and goals.

In this Supplement Ingredient Series episode, Nurse Doza breaks down glutathione — the master antioxidant your liver makes to fight inflammation, detox your body, and protect your brain. With roughly 1 in 4 people worldwide carrying a fatty liver, most are running on low reserves. Learn why glutathione is non-negotiable for energy, performance, and recovery — plus how to get your own vial to use at home.
Featured Partner: SHED
SHED delivers practitioner-grade glutathione in a vial you can use at home — the same master antioxidant Nurse Doza has administered through thousands of injections and IVs in clinical practice. Because the liver's ability to produce glutathione drops when it's fatty, inflamed, or overworked, supplementing directly is often the fastest way to restore energy, mental clarity, and detoxification pathways — exactly the mechanism discussed in this episode.

5 Key Takeaways
Glutathione is your body's master antioxidant. It's a tripeptide made in the liver that neutralizes free radicals, recycles other antioxidants like vitamin C and E, and powers detoxification pathways throughout the body.
Your liver is the glutathione factory. Peer-reviewed research confirms the liver is the central hub for glutathione production and systemic distribution — when hepatic function drops, so does your antioxidant defense system.
Fatty liver compromises antioxidant production. Global NAFLD prevalence estimates range from roughly 25–32% of adults, meaning a significant portion of the population has reduced capacity to make glutathione — which is exactly when fatigue, brain fog, and chronic inflammation start showing up.
Oral glutathione has poor bioavailability. Because glutathione is broken down by enzymes in the digestive tract, injections and IVs bypass digestion and deliver the molecule directly into circulation — which is why Nurse Doza and many functional practitioners prefer this route.
Glutathione isn't just a detox tool — it's a performance tool. Higher glutathione levels are clinically linked to better energy, sharper cognition, faster recovery, and lower systemic inflammation. That's why it's a cornerstone ingredient in Nurse Doza's practice.
