What a Healthy Gut Is Quietly Doing For You

A healthy gut is not just an absence of bloating. It’s an entire operating system running in the background.

Start with the immune piece. Roughly 70 to 80 percent of your immune system lives in the gut lining. When your gut bacteria are diverse and well-fed, your immune system becomes less jumpy. It gets better at telling the difference between a real threat and a harmless shadow on the wall. That matters because true immune strength is not just about fighting harder — it is about knowing when not to fight. When they’re not — what researchers call dysbiosis, meaning an out-of-balance microbiome — your immune system can become more reactive. That reactivity shows up as inflammation, the common signal underneath autoimmunity, IBD, skin flares, and joint pain (Glassner et al., 2020, Journal of Allergy and Clinical Immunology). Inflammation is the signal pointing upstream — poor dietary choices and environmental exposures drive it, NOT genetics.

Then there’s the chemistry. When your gut bacteria ferment fiber, they make short-chain fatty acids — SCFAs for short — tiny molecules that feed the cells of your gut lining, calm the inflammatory signal, and help regulate blood sugar (Nogal et al., 2021, Gut Microbes). Translation: the same bugs that digest your salad are also the ones keeping your energy steady at 2 p.m.

And then there’s your head. A 2022 systematic review in the International Journal of Molecular Sciences mapped the gut-brain axis in depression and found that the microbiome influences mood, anxiety, and cognition through the vagus nerve, neurotransmitters, and immune signaling (Alli et al., 2022). Most of your serotonin is made in the gut. Read that again.

In my own body, repairing the damage caused by undiagnosed celiac through nutrition and reversing fibromyalgia and chronic fatigue didn’t just give me my digestion back. It gave me my mornings back. My brain back. Fifty-five pounds gone in twenty-five weeks back. Bio-individually — your timeline will be yours. But the principle holds.

The Protocol — One Thing You Can Do Today

Here’s the truth I keep coming back to: you don’t need a new supplement stack. You need to feed the bugs that are already trying to work for you.

The single most-studied lever for a healthier gut is fiber diversity — not fiber quantity, diversity. A 2023 review in Proceedings of the Nutrition Society on dietary fibre and health and a 2022 systematic review on inulin-type fructans both land in the same place: a wide variety of plant fibers feeds a wide variety of beneficial bacteria, and that diversity is what produces the SCFAs your gut lining is begging for (Mathers et al., 2023; Hughes et al., 2022).

Here’s your one micro-action for today. Pick three plants you haven’t eaten this week and put them on your plate before bed. That’s it.

If you want the fuller picture, this is the rhythm I walk clients through:

• Add 30+ different plants a week. Herbs count. Spices count. A pinch of parsley is a plant.

• Two tablespoons of raw butter a day as an anti-inflammatory fat. Skip the bottled oils — they oxidize.

• Dress your food with fresh-squeezed lemon, apple cider vinegar, salt, and pepper. Your salad does not need a bottle.

• Pull gluten and pasteurized cow dairy out of your diet for three weeks and watch what your body tells you. (Raw dairy is a different conversation — and beneficial long-term; pasteurization is the problem.)

• One fermented food a day — sauerkraut, kimchi, miso, raw kefir. A forkful is enough.

• Sleep is a gut intervention. Aim for a 10 p.m. lights-out for two weeks and notice the difference.

• Move after meals. A ten-minute walk after dinner steadies your blood sugar and feeds your bugs.

If you’ve got a specific concern — antibiotic recovery, IBS, an autoimmune flare — always consult your naturopathic physician before making changes to your treatment plan. As a certified integrative health coach, I share evidence-based lifestyle and nutritional approaches. Your naturopathic physician is the right partner for what’s specific to you.

You’ve cleaned up your nutrition. You’ve cut the gluten, swapped the sugar, drunk the green stuff. And somewhere between the seventeenth supplement and the third elimination plan, a quiet voice started whispering: maybe this just isn’t going to work for me.

I want to talk to that voice today. Because the research is catching up to what I’ve watched in my own kitchen and with every woman I’ve coached: the story running in the back of your head while you eat is doing as much work on your body as the food on the fork. Not instead of nutrition. Alongside it. And it’s the one lever almost nobody hands you in a ten-minute doctor’s appointment.

The Deep Dive: Your Mindset Is Tissue, Not Fluff

Here’s the truth I keep coming back to: mindset is not a motivational poster. It’s biochemistry. The thoughts you rehearse on repeat shape the hormones your body runs on — cortisol, adrenaline, insulin, oxytocin — and those hormones decide whether your gut barrier holds the line or springs a leak.

A 2023 paper in Progress in Cardiovascular Diseases by Alan Rozanski laid this out cleanly: a vitality-based outlook — rooted in energy, agency, purpose, and a sense of future health — is closely tied to better cardiovascular and overall health trajectories. Not as a side note. As a measurable factor. And in 2025, Zhou and colleagues published a piece in Pediatric Allergy and Immunology on mindset in food immunotherapy showing that how a patient frames the work changes how the immune system responds to it. The nervous system is listening.

The flip side is real too. Ettman and colleagues, in a 2023 scoping review in Translational Psychiatry, traced how chronic financial strain and the helplessness that rides with it correlate tightly with depression — and depression cranks up systemic inflammation, which is the common signal underneath autoimmunity, joint pain, stubborn weight, and brain fog. Inflammation isn’t the root cause. It’s the messenger pointing upstream. Poor dietary choices and environmental exposures drive that inflammation — not genetics. And one of those upstream roots is the story you’re telling yourself at 6 a.m. before your feet even hit the floor.

Now — bio-individuality matters here: mindset work is not a substitute for finding the food trigger, repairing the gut barrier, or addressing a toxic exposure. Macnamara and colleagues, in a careful 2023 meta-analysis in Psychological Bulletin, made the point that mindset interventions are not magic on their own. They’re a multiplier. They make the rest of the work land. That’s exactly how I want you to hold this: not as the answer, as the amplifier.

The Protocol: One Shift Before Breakfast

Here’s what I tell my clients in week one when we add the mindset spoke to the wheel. Pick one. Do it tomorrow. Notice what changes.

• The 60-second morning frame. Before your feet touch the floor, name three things your body did well yesterday and express gratitude for them. Digested a meal. Walked you up the stairs. Held you through a hard conversation. This is not gratitude theater — it’s pattern interruption. You’re training the nervous system to scan for function instead of failure.

• Swap one phrase. Retire “my body is broken” and replace it with “my body is asking to be heard.” Say it out loud. Words shape biochemistry. This isn’t woo — it’s wiring.

• Eat one meal in silence. No phone, no screen, no scrolling. Chew. Your vagus nerve runs the parasympathetic show, and digestion only happens when your nervous system feels safe.

• Move for ten minutes outside. Morning sunlight on your skin and eyes sets the cortisol curve for the whole day. Walk slowly. This is not exercise; it’s a signal.

• Add two tablespoons of raw butter to the day. Real fat feeds the brain that’s doing all this reframing. The fat-soluble vitamins in raw butter (A, D, K2) are nervous-system nutrients.

• Name the upstream root cause. Each evening, ask: where did my body knock today, and which of the five rooms might it be pointing to — food, gut, toxin, nutrient, or stress? Find the hole and then fix it.

• Skip the bottled oils. Dress your food with fresh-squeezed lemon, apple cider vinegar, salt, and pepper. Oxidized oils drive the very inflammation you’re working to settle.

Always consult your naturopathic physician before making changes to your treatment plan, especially if you’re working through autoimmunity or a complex picture. Mindset is a spoke on the wheel — it is not the whole wheel.

The Sovereign Source

The practice is free. The shift is yours. There’s no supplement on earth that replaces deciding, at 6 a.m., that your body is on your side.

Follow the money on the mindset-industry side: most of what’s sold as “manifestation” is a $497 course dressed up as common sense. You don’t need that. You need ten minutes, a window, and your own voice.

The Bridge

Here’s what I want from you this week. Pick ONE thing from the protocol. Just one. Do it for seven days. Then hit reply and tell me what you noticed — I read every response, and your story is often the thing another reader needs to hear.

If this landed, forward it to the friend who keeps telling you she’s tried everything. And if someone forwarded it to you, you can subscribe right here so the next one shows up in your inbox.

Be well, Angela

You’re lying there at 3:14 a.m. again. Your calf cramped at midnight. Your jaw is clenched. Your heart’s doing that flutter thing. You’ve already swapped your wine for chamomile, your screens for paperbacks, your mattress for something that cost more than your first car — and you’re still wired, still tired, still wondering what on earth is wrong with you.

Let me offer a different lens. Roughly half of Americans aren’t getting enough magnesium from food, and your body burns through what you do have faster every time you’re stressed (Fiorentini et al., 2021, Nutrients). It’s not a personality flaw. It’s a mineral your body cannot make and the soil can barely give you anymore.

Why magnesium runs the show

Magnesium is a cofactor in more than 300 enzyme reactions in your body. Translation, in plain English: it’s a tiny helper your cells need to do over 300 different jobs — making energy, relaxing muscles, calming nerves, regulating blood sugar, building bone, steadying your heartbeat. When it’s low, a lot of small things go sideways at once, and nobody connects the dots because the dots don’t look related.

Here’s what the research actually says, by name:

• Sleep. A 2023 systematic review in Biological Trace Element Research (Arab et al.) and a 2021 meta-analysis in BMC Complementary Medicine and Therapies (Mah et al.) both found magnesium supplementation associated with better sleep quality, especially in older adults and those with insomnia.

• Stress. Pickering and colleagues described the magnesium-stress relationship in Nutrients (2020) as a vicious circle — stress depletes magnesium, and low magnesium makes you more reactive to stress. So you spiral.

• Migraines. A 2025 Nutrients review (Dominguez et al.) lays out the role of magnesium in migraine prevention.

• Muscle cramps and performance. Wang et al. (2017) in Magnesium Research found supplementation improved muscle fitness measures.

• Brain and bone. Chen et al. (2024) in Advances in Nutrition linked higher magnesium status to better cognitive outcomes, and Capozzi et al. (2020) in Maturitas put magnesium right next to calcium, vitamin D, and K2 in the skeletal-health conversation.

• Heart and hormones. Tangvoraphonkchai (2018) and Parazzini (2017) show clinical relevance in cardiovascular and gynecological practice, respectively.

That’s a lot of spokes on one wheel.

In my own practice, I see magnesium deficiency show up as the thing nobody asked about. The ten-minute doctor’s appointment doesn’t have time for it. Bio-individually — your symptoms may be sleep, your sister’s may be migraines, your client’s may be constipation and anxiety — same hub, different spokes. Find the hole and then fix it.

The Protocol — what to actually do this week

Here’s where you stop reading and start doing. Pick one. You don’t need all of these on day one.

• Eat magnesium-rich whole foods every single day. Pumpkin seeds, almonds, cashews, spinach, Swiss chard, avocado, black beans, dark chocolate (70%+), wild-caught salmon. A small handful of pumpkin seeds is roughly 150 mg — about a third of a day’s needs in five chews.

• Try the one-today move: tonight, eat one ounce of pumpkin seeds with dinner and notice how you sleep. A small experiment you can run after you finish this email.

• Add an Epsom salt bath two nights a week. Magnesium sulfate, 20 minutes, warm water. Your skin will take what it needs. Bonus: it forces you off your phone.

• Drop the soda and slow the coffee. Both are magnesium thieves. You don’t have to quit — you have to notice.

• Consider a topical magnesium spray on your calves and feet before bed if cramps are the issue.

• If you’re going to supplement orally, choose the form that matches the job. Magnesium glycinate tends to be the gentle, sleep-and-nerves option. Magnesium citrate moves the bowels — useful if you’re constipated, inconvenient if you aren’t. Magnesium oxide is poorly absorbed — skip it. Magnesium L-threonate is the form most studied for cognition.

• Pair it with whole-food fats. Two tablespoons of raw butter, avocado, walnuts — magnesium does its best work in a body that has the raw materials to use it.

• Plan ahead. Put the seeds, the dark chocolate, the spinach on the grocery list this week. Every meal is a vote.

A word of sovereignty: if you have kidney issues, take heart medication, or are pregnant, magnesium dosing is not a guess-and-go situation. Always consult your naturopathic physician before making changes to your treatment plan.

Quality matters

Magnesium is one of those minerals where quality matters more than the label promises. Drugstore bottles often lean on magnesium oxide because it’s cheap — and your body barely absorbs it. Follow the money: the cheapest form is rarely the most useful one. When you shop, look for glycinate, citrate, or L-threonate, and skip anything padded with mystery fillers and proprietary blends.

Food first, always. Supplements fill the hole food can’t reach.

The Bridge

Here’s the truth I keep coming back to: your body isn’t broken — it’s asking to be heard. The 3 a.m. ceiling stare, the calf cramp, the clenched jaw, the migraine that arrives like clockwork — those are messages, not malfunctions. Magnesium is one quiet answer hiding in plain sight.

You cleaned up your nutrition. You added the bone broth, the fermented foods, the L-glutamine your favorite podcast swore by. And the bloating still shows up at 4 p.m. like an uninvited guest. So when somebody tells you to point a red light at your belly, I get it — you roll your eyes. I would have too. Until I read the research. Photons of a specific wavelength, applied to the abdomen, appear to shift the gut microbiome itself. Not as a magic wand. As one more spoke on the wheel — and possibly a spoke you’ve been missing.

What the science actually says (in plain English)

Red light therapy goes by a fancier name in the journals: photobiomodulation, or PBM. The idea is simple. Specific wavelengths of red and near-infrared light (roughly 630 to 850 nanometers) penetrate the skin, reach the mitochondria — the little energy factories inside your cells — and nudge them to make more ATP, which is the cellular fuel that runs everything from immune response to tissue repair.

Here’s where it gets interesting for your gut. A 2023 review by Jahani-Sherafat and colleagues, published in Gastroenterology and Hepatology from Bed to Bench, looked at photobiomodulation in conditions tied to dysbiosis — that’s the medical term for an out-of-balance gut microbiome, where the wrong bacteria have outvoted the right ones. The authors concluded that PBM appears to modulate the microbiome itself, increasing populations of beneficial bacteria and calming the inflammatory signaling that comes with dysbiosis. In animal studies, abdominal red light shifted bacterial diversity in a direction that tracked with reduced gut inflammation.

Let me say what that does and doesn’t mean. It does NOT mean you can shine a light on your belly and skip the work of cleaning up your nutrition. Inflammation is a signal, not a root cause — it’s pointing upstream to food triggers, gut barrier dysfunction, and environmental exposures. Poor dietary choices and environmental exposures drive inflammation NOT genetics. What it DOES suggest is that for many people — bio-individually — red light may be a useful adjunct that helps your cells do the repair work your nutrition is already setting up. In my experience, the clients who see the most from these tools are the ones who’ve already pulled the obvious triggers off their plate. The light is the amplifier, not the foundation.

The Protocol: a 10-minute experiment you can run today

You don’t need a clinic. You don’t need a four-figure panel. You can start with a small at-home device and see how your body responds over two to four weeks.

Here’s a starting framework — adjust to your bio-individuality and the device you have:

• Wavelength: Look for a device in the 630–660 nm (red) and/or 810–850 nm (near-infrared) range. Both have research behind them.

• Distance and time: Start at 6 to 12 inches from bare skin, 10 minutes per session, once daily. More is not better.

• Where: Over the abdomen — lower belly, around the navel, and the lower right quadrant where the ileocecal valve lives.

• When: Morning is ideal. It pairs well with natural sunlight on your skin and eyes within the first hour of waking, which is its own circadian medicine and costs you nothing.

• Track it: Keep a two-line journal. One line for what you ate. One line for how your gut felt. Two weeks of data tells you more than two months of guessing.

• Pair it with the basics: Two tablespoons of raw butter daily, wild-caught fatty fish a couple of nights a week, fresh-squeezed lemon and apple cider vinegar instead of bottled oils, and pasteurized cow dairy off the plate during any reset window.

• Sunlight first: Before you spend a dollar on a device, get 10 minutes of morning sun on your skin and in your eyes (no sunglasses, don’t stare at it). Free, ancient, and the original photobiomodulation.

Always consult your naturopathic physician before adding red light therapy, especially if you have a photosensitizing condition, are pregnant, or have a history of skin cancer. As a certified integrative health coach, I share evidence-based lifestyle approaches.

The Sovereign Source

A few honest notes on sourcing without the hype. The red light therapy market exploded, and most of what’s on the shelf is overpriced or underpowered. Look for a device that publishes its irradiance numbers (the actual power output) and the specific wavelengths. If a company won’t tell you, that’s your answer.

For the nutritional side of this work — the foundation that makes any light therapy worth trying — professional-grade supplements through a practitioner dispensary like Fullscript are where I send my clients when they want clean sourcing without the Amazon roulette. For essential oils that pair beautifully with gut work (peppermint, ginger, fennel), doTERRA’s therapeutic-grade line is what I keep in my own arsenal.

If your situation is medically complex — long-standing dysregulation, multiple diagnoses, a body that’s not responding to nutrition alone — Dr. Glidden’s homeopathic work at leavebigpharmabehind.com is where I point people who’ve already done the basics and need a deeper bench. Always consult your naturopathic physician before making changes to your treatment plan.

Not really. Not skin-on-earth. Think about it — when was the last time your bare feet were on actual dirt, grass, or wet sand for more than thirty seconds? For most of us, the answer is sometime around childhood. We sleep in beds off the floor, walk on rubber soles, drive in cars, and live in buildings wrapped in synthetic everything. Meanwhile, every human who came before us spent hours a day in direct contact with the planet. You’ve tried the supplements. You’ve cleaned up the nutrition. You’re still inflamed. What if part of what your body is asking for is something you can do barefoot, for free, in the next ten minutes?

What grounding actually is — and what the research says

Grounding (also called earthing) is exactly what it sounds like: putting your skin in direct contact with the surface of the earth. Grass, soil, sand, unsealed stone, a natural body of water. The premise is simple — the earth carries a mild negative electrical charge, and when you touch it, free electrons transfer into your body. Those electrons appear to neutralize excess free radicals, which are the unstable molecules that drive chronic inflammation when they pile up.

This isn’t woo. A 2015 review published in the Journal of Inflammation Research, led by Dr. James Oschman and colleagues, pulled together the existing studies on grounding and reported measurable shifts in inflammation markers, cortisol rhythms, blood viscosity, and pain scores when subjects were grounded versus not. A separate 2010 study in the Journal of Alternative and Complementary Medicine found that grounding reduced delayed-onset muscle soreness and shifted white blood cell counts in a pattern consistent with a calmer inflammatory response. Mayo Clinic and Cleveland Clinic have both, more cautiously, acknowledged the early but promising data on stress and sleep.

Here’s how I frame it for clients. Inflammation is a signal — a messenger pointing upstream to a food trigger, a gut barrier issue, a toxic exposure, a nutrient gap, or a nervous system stuck in overdrive. Poor dietary choices and environmental exposures drive that fire NOT your genetics. Grounding doesn’t fix the upstream cause. What it appears to do, for many people, is take the volume down on the body’s stress and inflammatory response so the rest of the work — the food, the sleep, the gut repair — has room to land. In my own healing, the days I spent barefoot in the garden were never the days my pain was worse. Bio-individually — your mileage will vary — but the principle is sound.

The Protocol: how to actually do this

You don’t need a gadget. You need skin and earth. Start here:

• Twenty minutes, bare feet, on grass or dirt. That’s the entry-level dose most of the research used. Morning sun + bare feet is a two-for-one — you get grounding plus circadian light cues for better sleep.

• Wet grass or wet sand conducts better than dry. Dew in the morning, the edge of a lake, damp soil after a rain — all stronger conductors than parched ground.

• Sit, don’t just stand. Hands on the ground count. Lie down if you can. More skin, more contact. (I actually love to do “grass angels” while I lay under a tree.)

• Concrete poured directly on earth (unsealed) works. Asphalt, sealed concrete, painted decks, and rubber soles do not. Wood floors don’t either.

• Try it before bed and notice your sleep. Many of my clients report falling asleep faster after even ten minutes of evening grounding.

• Stack it with a walk. Five minutes barefoot at the start or end of your daily walk — sovereignty doesn’t have to be a separate appointment on your calendar.

• Pair it with breath. Four counts in, six counts out, for two minutes while your feet are on the earth. You’re telling your nervous system the threat is over.

One anti-inflammatory note while we’re here: keep skipping the bottled oils. Two tablespoons of raw butter a day, wild-caught salmon a couple of nights a week, and dressings built from fresh-squeezed lemon, apple cider vinegar, salt, and pepper will do more for the fire than bottled oils ever will. Always consult your naturopathic physician before making changes to your treatment plan, especially if you’re managing a circulatory condition or are pregnant.

The Sovereign Source

The best source is the one outside your back door. No purchase required, no app, no subscription. That’s the part I love — this is one of the few health practices that costs nothing and that no industry can monetize, which is probably why you’ve never heard it come up in a ten-minute doctor’s appointment. Follow the money: there’s no money here. There’s just you and the planet you live on.

If getting outside barefoot is not realistic — perhaps you live in a high-rise, deal with long winters, have mobility limitations, or simply do not have easy access to clean, natural ground — there are grounding mats and sheets marketed as alternatives. These products typically plug into the grounding port of a standard outlet. I personally prefer direct contact with the earth whenever possible and am not especially drawn to grounding products, but some people do report benefits from using them. I do not sell them, recommend a specific brand, or have an affiliate link. Please do your own research, read both positive and critical reviews, and speak with your naturopathic physician first if you have cardiac, circulatory, implanted-device, or other medical considerations. If your inflammation picture is more advanced or medically complex, Dr. Glidden’s work at leavebigpharmabehind.com offers natural solutions beyond nutrition that go deeper than what a single newsletter can cover.

The Bridge

Here’s your homework, and it’s the easiest assignment I’ll ever give you. Tomorrow morning, before you check your phone, walk outside and put your bare feet on the ground for ten minutes. That’s it. Notice how you feel an hour later. Notice how you sleep that night. Then hit reply and tell me what you noticed — I read every email. If this issue helped you, forward it to the friend who’s been telling you she’s exhausted and doesn’t know why. And if you’re not subscribed yet, that’s the one click that keeps these landing in your inbox.

When did sunshine become the villain? We slather, we shade, we scroll past the one free thing our bodies have been asking for since we crawled out of the cave. Then we wonder why our guts are a mess, our moods are flat, and our immune systems can’t tell friend from foe. Here’s the truth I keep coming back to: vitamin D isn’t really a vitamin. It’s a hormone. And it doesn’t just build bones — it talks to your gut, your microbes, and your immune system every single day. If you’re sick and tired of being fat, frumpy, and frazzled, this is one of the first dials I’d ask you to look at.

What vitamin D is actually doing down there

Let’s be clear: vitamin D is not just about calcium. It’s a signaling hormone with receptors lining your gut, your immune cells, and the tissues that keep your intestinal barrier sealed shut. When those receptors go quiet, the wheels start coming off.

A 2020 review in The Journal of Steroid Biochemistry and Molecular Biology (Fakhoury et al.) laid it out plainly — vitamin D modulates the gut barrier, shapes the microbiome, and tunes the immune response inside the intestinal lining. Translation: it helps decide whether your gut wall is a sturdy fence or a sieve. Ghaly and colleagues, writing in Expert Review of Gastroenterology & Hepatology in 2019, mapped the same conversation in inflammatory bowel disease — dietary vitamin D, sunshine exposure, and the fecal microbiome are all part of one feedback loop. They’re not separate spokes. They’re the same wheel.

It goes further. Zhan et al. (2024, World Journal of Gastrointestinal Oncology) describe a vitamin D — gut flora — immune system nexus that may matter for colorectal cancer prevention. Matsui et al. (2019) found food allergy is linked to season of birth, sun exposure, and vitamin D deficiency. Mărginean and colleagues (2022, Diagnostics) traced the same crosstalk through pediatric digestive disorders.

In my own story, the gut damage from undiagnosed celiac left me malnourished in ways that didn’t show up on a standard panel — and vitamin D was one of the quiet ones. I was tired, achy, and inflamed. Bio-individually — your numbers will be yours — but the principle holds: a depleted gut and a depleted vitamin D status almost always travel together.

Remember, inflammation is a signal pointing upstream. Low vitamin D doesn’t cause your symptoms on its own. It’s one of the spokes on the wheel you’ll find when you work at the root cause instead of chasing symptoms.

The Protocol — sunshine, food, and a smart test

Here’s what I tell my clients in week one. Stop guessing. Start gathering data, then stack the basics.

• Get tested. Ask your naturopathic physician for a 25-hydroxy vitamin D blood test. Know your number before you supplement.

• Sunshine, daily, for free. Ten to thirty minutes of mid-morning sun on bare skin (arms, legs, face) most days, dosed to your skin tone and latitude. No sunglasses. No burning. No guilt. This is the original prescription.

• Real food sources. Wild-caught salmon and sardines, pasture-raised egg yolks, cod liver oil, and mushrooms exposed to sunlight. Two tablespoons of raw butter daily as your anti-inflammatory anchor.

• Skip the bottled oils. Dress your food with fresh-squeezed lemon, apple cider vinegar, salt, and pepper, or a homemade whole-food dressing.

• Mind the dairy distinction. During a gut reset, pull out all dairy. Long-term, raw dairy carries beneficial nutrients and enzymes that pasteurized cow dairy has had cooked out of it. Pasteurized cow dairy is the problem, not dairy as a category.

• Move the lifestyle lever — sleep. Vitamin D and circadian rhythm are roommates. Get morning light in your eyes within an hour of waking, and you’re already doing the work.

• Feed the microbes. Fiber-rich vegetables, fermented foods like sauerkraut and kimchi, and bone broth give the bugs a reason to cooperate with the hormone signaling.

If your number comes back genuinely low, supplementation is a conversation — not a guess. Always consult your naturopathic physician before making changes to your treatment plan, and ask about pairing vitamin D3 with K2 and magnesium so the team works together. Find the hole and then fix it.

The Sovereign Source

When you’re ready to source professional-grade vitamin D3/K2 or magnesium, work with your naturopathic physician and use a clinician-vetted dispensary like Fullscript rather than whatever is loudest on the shelf at the big-box store. Follow the money — most retail supplements are formulated for margin, not for absorption. You want third-party tested, whole-food-based where possible, and dosed to your actual lab values.

For the sun part of this equation, you don’t need a store. You need a calendar. Put a daily walk on it before lunch and protect that twenty minutes the way you’d protect a meeting with someone important — because that’s exactly what it is. If your situation is more medically complex than basic nutritional repair, that’s when I’d point you toward Dr. Glidden’s work at leavebigpharmabehind.com, where homeopathy and additional natural solutions can layer on top of nutrition.

The Bridge

If this issue lit something up — if you’re nodding because the fatigue, the bloating, the mood, and the immune chaos all feel like one tangled rope — that’s because they probably are. The gut is the opening chapter, and vitamin D is one of the first signals worth listening to. Sovereignty starts with knowing your numbers, eating real food, and stepping outside on purpose. Every meal is a vote for you. Every walk in the sun is a vote for you. You are the expert on you.

Until next time, be well.

Stay curious, stay sovereign.

That’s the wall standing between what you swallow and your bloodstream — a barrier thinner than a piece of tissue paper, doing the work of deciding what belongs inside you and what doesn’t. When that wall gets holes in it, undigested food particles, toxins, and bacterial fragments slip through and trigger the immune system into a fight it was never meant to pick. That’s leaky gut. It’s not a buzzword. It’s measurable, it’s well-documented in the research, and for many of the women I coach, it’s the opening chapter of a story that includes fatigue, brain fog, joint pain, stubborn weight, and autoimmunity.

Let’s pull it apart.

What leaky gut actually is (and why your body cares)

The medical term is intestinal permeability. Your small intestine is lined with cells held together by tight junctions — little protein zippers that open and close to let nutrients through and keep everything else out. When those zippers get stuck open, you’ve got a leak.

This isn’t fringe. A 2019 review in Gut by Camilleri laid out the mechanisms and how we measure it in humans. Di Vincenzo and colleagues published a 2024 narrative review in Internal and Emergency Medicine connecting gut microbiota, intestinal permeability, and systemic inflammation — the same signal I keep pointing to in this newsletter. Neurath’s 2025 piece in The Lancet Gastroenterology & Hepatology called the intestinal barrier pivotal in health, inflammation, and cancer. And Malesza’s 2021 Cells review showed how a high-fat, Western-style nutrition pattern drives the whole mess.

Here’s the part that matters for you: when that barrier leaks, your immune system starts reacting to proteins it was never supposed to meet. Over time, that chronic reaction shows up as a common thread under autoimmunity, fibromyalgia, chronic fatigue, eczema, thyroid trouble, and weight that won’t budge. Inflammation isn’t the cause — it’s the signal pointing upstream to the leak. Poor dietary choices and environmental exposures drive that fire NOT your genetics.

I learned this the hard way. Fibromyalgia had me in bed by 4 p.m. I hadn’t yet been diagnosed with celiac disease, and it took me three and a half years to connect the dots. Once I pulled gluten out of my diet and started repairing the damage caused by celiac through nutrition, the fibromyalgia and chronic fatigue reversed. Bio-individually — your story will look like yours — but the principle holds: find the hole and then fix it.

The first-week repair protocol

One week won’t close every junction. But one week of feeding the barrier instead of beating it up will tell your body you’re finally listening. Here’s what I walk my clients through in week one:

Foods to add:

• Bone broth, simmered long and slow — collagen and glutamine are the raw materials your gut lining rebuilds from (Aleman 2023 reviewed the ingredients that support barrier repair)

• Steamed leafy greens and colorful vegetables at every meal

• Wild-caught fatty fish — salmon, sardines — two to three times a week for omega-3s

• Two tablespoons of raw butter a day as a daily anti-inflammatory habit

• Whole-food fats: avocado, nuts, seeds, ghee, coconut

• Fermented vegetables (sauerkraut, kimchi) in small daily doses if tolerated

Foods to pull out for seven days:

• Gluten, in every hiding place

• All dairy during the reset (the problem is pasteurized cow dairy; raw dairy is a longer conversation)

• Added sugar and industrial seed oils

• Bottled oils — dress your food with fresh-squeezed lemon, apple cider vinegar, salt, and pepper, or a homemade whole-food dressing instead

Lifestyle lever: Sleep. Seven to nine hours, in a dark room, screens off an hour before bed. Barrier repair happens overnight, and a short-sleep week undoes a clean-nutrition week. This isn’t optional — it’s where the healing actually lands.

Always consult your naturopathic physician before making changes to your treatment plan, especially if you’re working through a diagnosed condition.

The Sovereign Source

When clients ask where I send them for professional-grade probiotics and gut-barrier support, the answer is Fullscript. It’s the dispensary I trust because the sourcing is clean and the potency is real — not the drugstore aisle where you don’t know what’s in the bottle. Follow the money on grocery-store probiotics sometime; you’ll see why I’m picky.

A quick note on Dr. Glidden’s work at leavebigpharmabehind.com — I’m an affiliate and a client, and he’s a tremendous resource for advanced or medically complex situations where nutrition alone isn’t enough. For basic gut repair and inflammation work, that’s what my own programs are for. Start where you are.

Your next step

If this is the week you stop chasing symptoms and work at the root cause instead, I built something exactly for that. 7 Days to Reset Your Gut is the guided, structured version of everything I just laid out — meal framework, daily actions, and the coaching walk-through so you’re not doing it alone. It’s normally $97; readers of this newsletter get it for $27.

Start 7 Days to Reset Your Gut — $27

Your body isn’t broken. It’s asking to be heard. Every meal is a vote, and this week you get to cast seven days of them in a row.

Stay curious, stay sovereign.

Be well, Angela
