How To Reduce Inflammation: 11 Episodes on the Gut, the Vagus Nerve, and Real Biomarkers

The practical answer to how to reduce inflammation: feed the gut barrier, fix insulin resistance, and calm the nervous system. Eleven podcast episodes on fiber, CRP testing, vagus nerve activation, and what supplements actually do.

The fastest lever most people have is dietary fiber, and the reason is anatomical: roughly 70% of the immune system sits in the lining of the gut, and that single layer of cells rebuilds itself every 3 to 5 days. Dr. Will Bulsiewicz makes the case across two of the episodes below. Gut microbes ferment fiber into short-chain fatty acids (acetate, propionate, butyrate), which he calls the most anti-inflammatory nutrients he has come across, and butyrate powers the tight-junction proteins that hold the barrier together. Choices you make today reshape the microbiome by tomorrow. Alongside that, two other levers show up repeatedly: correcting insulin resistance, and activating the vagus nerve, which Dr. Kevin Tracey describes as the body's brake on inflammation.

These 11 episodes come from our library of podcast summaries, weighted toward the past year, so this is a snapshot of what the best recent conversations say about inflammation. The Dr. Hyman Show appears four times because functional medicine treats chronic inflammation as its central subject, and those episodes carry the most concrete testing and dietary detail in the set.

Each entry explains why it earns its rank, the takeaways worth acting on, and a quote from the conversation. Every summary links to our full free breakdown, and most include the official video. Three threads run through the whole list, and we unpack them after the ranking: inflammation as a downstream symptom, the nervous-system route as a free intervention, and the gap between the markers you can measure and the ones that matter.

1. Gut Health Expert: These 4 Nutrients Can Heal Your Gut Overnight

Rich Roll Podcast · Dr. Will Bulsiewicz · 2h 26m · January 2026

The most complete mechanism-to-menu episode in the set, and the one that makes inflammation feel tractable. Bulsiewicz spends two and a half hours connecting a single-cell gut barrier to 130+ chronic conditions, then quantifies the damage side too: 60% of adult calories now come from ultra-processed food, every 10% of diet from those foods raises death risk 14%, and excess sodium depletes lactobacillus by 90% while triggering inflammatory TH17 cells. The payoff is the timeline. The microbiome shifts within 24 hours and the barrier fully regenerates in 3 to 5 days, which means a week of better eating is measurable biology.

Key takeaways

  • Fiber reaching the colon becomes acetate, propionate, and butyrate. Butyrate fuels colon cells and powers the tight-junction proteins holding the gut barrier shut.
  • All 130+ inflammation-linked chronic conditions also show gut dysbiosis, which makes the barrier the highest-leverage target.
  • Americans average 3,600mg sodium against a 2,300mg recommendation, and that excess cuts beneficial lactobacillus by 90%.
  • The microbiome responds to a dietary change within 24 hours and the gut barrier rebuilds every 3 to 5 days, so the feedback loop runs in days.
  • Three of five people die from chronic inflammatory conditions, recorded on the death certificate as heart disease, cancer, stroke, or diabetes.
Three out of five people will die from chronic inflammatory health conditions. We may not look at the death certificate and call it inflammation. We might call it heart disease, cancer, stroke, or diabetes. But there is inflammation underpinning every single one of those health conditions. — Dr. Will Bulsiewicz

2. How Inflammation Really Works and How to Shut It Down

The Ed Mylett Show · Dr. Kevin Tracey · 1h 1m · January 2026

Tracey discovered the inflammatory reflex in 1998, and this hour is the clearest account of it anywhere in our library. He explains the loop end to end: the vagus nerve detects inflammatory molecules, signals the brain, and the brain signals back down to switch inflammation off. Then he shows what happens when that circuit is stimulated deliberately. An implant the size of a multivitamin delivering 400 microamps for one minute a day produced significant relief in 75% of rheumatoid arthritis patients who had already failed every biologic. The most provocative stretch is the depression argument: inject cytokines like TNF and IL-1 and you reliably produce sickness behavior, and cutting the vagus nerve in mice blocks it.

Key takeaways

  • The vagus nerve carries 200,000 fibers acting as brakes on inflammation. When the brakes fail, inflammation drives the diseases that kill two-thirds of the 60 million people who die each year.
  • FDA-approved vagus nerve stimulation reached 75% effectiveness in severe rheumatoid arthritis patients unresponsive to all medication, at one minute of stimulation per day.
  • Depression behaves like an inflammatory condition in roughly half of patients: vagus nerve stimulation works for 50% of depression cases.
  • Childhood stress leaves a lasting inflammatory signature. Elderly graduates showed an almost perfect inverse correlation between father's childhood income and current salivary cortisol, 50 to 70 years later.
  • Cytokines injected into mice or humans directly produce depression, appetite loss, and social withdrawal, which is how the body links immune activity to mood.
The fundamental discovery of the link between the vagus nerve and inflammation that we made was that the vagus nerve is sending signals that act like the brakes on your car. If inflammation is barreling down the hill and the brakes fail, all kinds of problems will occur. — Dr. Kevin Tracy

3. The Gut Doctor: This Is Why People Are Getting Sick

The School of Greatness · Dr. Will Bulsiewicz · 1h 32m · January 2026

Bulsiewicz's second appearance earns its own slot because it converts the theory into a shopping list and a schedule. Beans are the headline: the densest source of the fiber, polyphenols, and resistant starches that only microbes can break down. He also handles the objection that stops most people, which is gas and bloating on day three. Feeding a weak microbiome is like loading a bar too heavy for an injured muscle, so you build tolerance gradually and read the gas as evidence that anti-inflammatory compounds are being produced. The circadian material is the sleeper idea: the immune system runs its maintenance at night, and morning sunlight releases cortisol, the body's own anti-inflammatory.

Key takeaways

  • Start with beans in small daily portions and scale up as tolerance builds, treating the microbiome like a muscle in rehab.
  • Gas during the transition signals active fermentation, which is the same process producing short-chain fatty acids.
  • Cooling cooked beans, potatoes, or bread creates retrograde resistant starch, which lowers glycemic index and feeds beneficial bacteria. Reheating preserves it.
  • The immune system is nocturnal by design, which explains congestion at bedtime and next-morning soreness after training.
  • Morning sunlight triggers cortisol, described here as the body's own prednisone, which damps those overnight inflammatory symptoms.
Short-chain fatty acids which are acetate propriate and butyrate are hands down with total clarity the most anti-inflammatory nutrients that I've ever come across. — Dr. Will Bulsiewicz

4. It's Not Cholesterol. Inflammation Is What's Actually Causing Heart Disease

The Dr. Hyman Show · Dr. Cindy Geyer, Dr. Eric Topol, Dr. Aseem Malhotra · 1h 0m · July 2026

This is the episode that turns inflammation from an abstraction into a lab slip. Dr. Cindy Geyer's framing is the one to hold onto: high cholesterol with low inflammation may carry negligible risk, while high cholesterol plus elevated C-reactive protein sharply raises heart attack risk. The same hour explains why standard panels miss it, since conventional tests calculate LDL and skip particle size and number, so two people at LDL 130 can sit at wildly different risk. Insulin is the other blind spot: glucose and A1C can read normal while insulin runs ten times high, and that hyperinsulinemia drives inflammation years ahead of any diagnosis.

Key takeaways

  • Ask for C-reactive protein alongside cholesterol. Inflammation is what converts a cholesterol number into actual cardiovascular risk.
  • Advanced particle testing (NMR CardioIQ) reveals size and count, distinguishing large fluffy particles from the small dense inflammatory ones.
  • Fasting insulin catches problems years before glucose or A1C move. Insulin can run 10x normal on a perfect blood sugar reading.
  • Only 12.2% of Americans are metabolically healthy, and two-thirds of normal-weight people carry pre-diabetic metabolic profiles.
  • 80% of heart disease and diabetes cases are considered preventable through diet and lifestyle, with inflammation driven by chronic stress, poor sleep, loneliness, inactivity, and ultra-processed food.
Cardiovascular disease is an inflammatory process that it's not just about cholesterol, but there's ongoing inflammation. — Dr. Cindy Geyer

5. The Nerve That Controls Inflammation, and How to Activate It

10% Happier · Dr. Kevin Tracey · 1h 25m · April 2026

Tracey's second conversation is the actionable counterpart to his first, and it is the only episode here that hands you a free intervention with a stopwatch on it: inhale 3 seconds in two short breaths to fill the lungs, exhale 7 seconds through pursed lips, six cycles a minute, 5 to 10 minutes daily. What makes it valuable is his restraint about it. He is openly skeptical of the vagal-tone industry, points out that HRV has no measurement consensus and varies by device, posture, and what you ate, and cautions that improving vagal tone to the heart says little about the other 199,999 fibers. He also supplies the best analogy for autoimmunity in our corpus.

Key takeaways

  • Breathe in for 3 seconds and out for 7 through pursed lips, about six cycles per minute, for 5 to 10 minutes a day. It costs nothing and has measurable cardiovascular effects.
  • HRV is a weak proxy for vagal tone: algorithms differ across wearables, and readings shift with posture, food, and sampling window.
  • The high-frequency band of spectral analysis is the closest available indicator of vagus activity to the heart.
  • Slower resting heart rate, which reflects higher vagus activity, predicts all-cause longevity in population studies like Framingham.
  • In autoimmune conditions the immune system massively overcommits, and current immunosuppressants carry cancer, sepsis, and tuberculosis risk.
I like to describe the chronic inflammation that occurs with autoimmune conditions like rheumatoid arthritis or inflammatory bowel disease. It's almost as if the immune system is calling in the full power of the army and the navy and the air force to the site of a few elderly residents protesting the food in their nursing home. — Dr. Kevin Tracy

6. NEW Science: Your 'Immune Age' Predicts How Long You'll Live

Feel Better, Live More · Dr Rangan Chatterjee with Dr. Jenna Macciochi · 1h 56m · April 2026

Immunologist Jenna Macciochi supplies the lever the food-focused episodes leave out, and she supplies it with a number attached: teaching self-compassion over six to eight weeks measurably lowered inflammatory markers in blood. Her reframe is the most useful idea on this page for anyone who already eats well and still runs hot. The immune system reads chronic fear and harsh self-talk as danger, and inflammation is the response it has available. She also reframes the immune system itself as a wellness system woven through gut, skin, brain, and blood vessels, sitting at the center of heart disease, Alzheimer's, cancer, and metabolic syndrome.

Key takeaways

  • Six to eight weeks of self-compassion training lowered measurable inflammatory markers, making it a direct physical intervention.
  • Chronic stress and negative self-talk signal danger to the immune system, which primes inflammation with no physical threat present.
  • The immune system is shaped after birth, largely through microbial exposure, which is why environment and gut microbiome training matter so much in early life.
  • UK lifespan averages about 80 years against a health span of about 60, a 20-year window where people are alive while unwell.
  • Immune function is distributed everywhere: gut lining, skin, brain, and blood vessels, which is why inflammation shows up as such varied symptoms.
If you're always in fear, always speaking in a negative voice to yourself, your immune system is getting that message that there's something bad, like I need to be prepared for danger or damage. I need to keep this person safe. The only weapon I've got is inflammation. I'm going to whip that out. — Dr. Jenna Macciochi

7. Brain Inflammation: Stop These Three Diseases Before They Start

The Dr. Hyman Show · Dr. Chris Palmer, Dr. Richard Isaacson, Dr. Ray Dorsey · 49m · July 2026

Forty-nine minutes, and the highest stakes on the page. Hyman's line that the brain has few ways of saying ouch does real work here: depression, autism, Alzheimer's, and Parkinson's all present with inflamed brains, and you feel none of it directly. What lifts this above a scare piece is Dr. Richard Isaacson's claim that intensive multimodal lifestyle intervention moved brain biomarkers further than the billion-dollar amyloid drug trials, plus concrete testing targets. Homocysteine above 14 raises Alzheimer's risk by 50%, and the Vitacog trial showed B-complex both improved memory and slowed brain shrinkage in people with elevated homocysteine.

Key takeaways

  • Get baseline numbers for homocysteine, vitamin D, and omega-3, plus estrogen status for women, and treat them as brain-inflammation markers.
  • Homocysteine above 14 raises Alzheimer's risk 50%. B12, folate, and B6 improved memory and slowed brain atrophy in the Vitacog study.
  • Multimodal lifestyle intervention combining exercise, nutrition, vitamins, sleep, stress management, and cognitive engagement outperformed amyloid-targeting drugs on biomarkers.
  • Bioidentical HRT started during perimenopause improved Alzheimer's-associated biomarkers, with better brain volumes and less amyloid accumulation.
  • Adverse childhood experience scores predict obesity, diabetes, cardiovascular disease, and autoimmune risk through inflammation, oxidative stress, and insulin resistance.
The brain only has so many ways of saying ouch. When it's inflamed, you don't feel it. People who are depressed have inflamed brains. Autism has inflamed brains. Alzheimer's inflamed brain. — Dr. Mark Hyman

8. How To Boost NAD Levels To Fight Inflammation, Improve Recovery, and Slow Aging

Found My Fitness · Dr. Charles Brenner · 1h 54m · February 2026

The episode to listen to before spending money on an anti-inflammatory supplement, and it is unusually honest for the genre because Brenner discovered the molecule he is discussing. He puts real evidence behind nicotinamide riboside: eight randomized controlled trials show about 1 gram daily lowers IL-6, IL-10, and other inflammatory markers, with effects strongest in people who already have inflammatory conditions like COPD and long COVID, and one trial showing persistence three weeks after stopping. Then he argues the ordering that most supplement conversations skip. Inflammation, obesity, and disrupted sleep are what drain tissue NAD in the first place, so the lifestyle fix comes first and the capsule supports it.

Key takeaways

  • Eight human RCTs show nicotinamide riboside at roughly 1g daily lowers inflammatory markers including IL-6 and IL-10, with the clearest effects in existing inflammatory disease.
  • Blood NAD stays near 20 micromolar with age while tissue NAD in liver, muscle, brain, and cochlea declines, so blood tests mislead.
  • Inflammation itself consumes NAD: viral infection activates five PARP family members that burn through NAD as part of the innate immune response.
  • Obesity creates excessive NAD consumption driven by reactive oxygen species outpacing regeneration, with NADPH at the center.
  • Exercise raises expression of NAD biosynthetic genes, and circadian disruption degrades the NAD system, which puts sleep and training ahead of supplementation.
We know as for a fact... there are eight trials showing anti-inflammatory activity in human RCTs... NR lowers those inflammatory markers. Placebo doesn't. — Dr. Charles Brenner

9. From Debilitating Pain to Full Recovery: Terry Wahls on the Diet That Got Her Out of the Wheelchair

The Dr. Hyman Show · Dr. Terry Wahls · 1h 12m · June 2026

The single most specific dietary protocol in this collection, attached to the most dramatic outcome: a physician with progressive MS who went from a wheelchair to biking 18 miles within ten months. Wahls built it by reading mitochondrial science and reverse-engineering 20 target nutrients into a daily structure of 9 cups of vegetables, measured raw and split three ways. The reason it belongs on an inflammation page is that each third has a stated pathway: leafy greens for brain and eye protection, sulfur-rich cabbage-family vegetables and onions for glutathione and NRF2 activation, and brightly colored vegetables for the carotenoids tied to lower disease risk. Mushrooms and quality protein complete it.

Key takeaways

  • Target 9 cups of vegetables daily, measured raw: 3 cups leafy greens, 3 cups sulfur-rich (cabbage family and onions), 3 cups brightly colored.
  • Sulfur-rich vegetables drive glutathione production and activate the NRF2 detoxification pathway, which is the specific anti-inflammatory mechanism in the protocol.
  • Mitochondrial dysfunction runs beneath neurodegeneration including Alzheimer's, Parkinson's, progressive MS, anxiety, and depression.
  • Wahls stopped her mitochondrial supplements as an experiment and lost the ability to get out of bed within 36 hours.
  • Autoimmune disease is framed as genetic vulnerability plus infection (Epstein-Barr, strep, herpes) plus environmental load, so the approach shifts each environmental factor one at a time.
We're going to address all those environmental factors and shift every one of them from disease-promoting to health-promoting one by one at a pace that you and your family can manage. — Dr. Terry Wahls

10. How Your Immune System Works and How to Improve It

Huberman Lab · Dr. Max Krummel · 2h 27m · August 2026

Two and a half hours of foundation, and it changes how you read every other episode on this page. UCSF immunologist Max Krummel reframes immunity as a sensory network: roughly 10^11 T cells acting as individual sensors, continuously measuring biomolecules and judging what is in range. Under that model, inflammation is the system responding to readings outside its expected range, which explains why gut, metabolic, and stress inputs all register. His aging explanation is the standout: skin cells alone accumulate 10,000 to 30,000 mutations a day, so over decades every cell becomes genetically unique and the range of normal widens until genuinely dangerous cells blend in.

Key takeaways

  • The immune system works as a sensory apparatus of about 10^11 T cells curating the body, which is a wider job than pure defense.
  • Aging turns the body into a cellular mosaic, widening the range of normal until cancerous cells stop looking sufficiently different to trigger a response.
  • Infant immunity is deliberately suppressed for roughly the first 6 months, because rapid developmental gene expression would otherwise provoke autoimmunity.
  • Children get sick often because each pathogen is novel, and they recover fast because the responding system is strong.
  • Gut microbes supply metabolic capabilities absent from our own 20,000 genes, including bile acid components required to digest animal fats, so the immune system negotiates a detente with them.
It's like you have like 10 to the 11th little sensors going around you curating you. You know, making sure you're the right thing. And if they see something that's out of range, they can do something about it. You know, like the whole thing is magnificent. — Dr. Max Krummel

11. Undiagnosed Infections Are Silently Causing Chronic Disease

The Dr. Hyman Show · Dr. Richard Horowitz · 1h 17m · July 2026

The episode for the person who has already fixed the diet and still feels inflamed. Dr. Richard Horowitz has treated over 13,000 chronically ill patients who cycled through 30 to 40 doctors first, and his contribution is a checklist of drivers the food-and-fiber episodes cannot reach: tick-borne infection, mold, heavy metals, and nutrient deficiency. His most consequential claim is about autoimmunity, where molecular mimicry from an underlying infection generates antibodies against your own tissue, and treating the infection can clear the autoimmune markers. The diagnostic tell he offers is concrete and easy to self-check: migratory pain that moves unpredictably around the body.

Key takeaways

  • Migratory pain that moves around the joints, muscles, and nerves is the hallmark tell for tick-borne infection.
  • What gets called Lyme is usually three infections: Borrelia, Babesia, and Bartonella (18 to 19 subspecies), and standard commercial panels frequently miss Bartonella.
  • Autoimmune markers can arise from molecular mimicry triggered by infection or toxin, and often resolve once the underlying driver is treated.
  • Mycotoxins from mold are immunosuppressive and damage mitochondria, and 20% of his patients carry chronic variable immune deficiency or an IgG subclass deficiency.
  • Autism and Alzheimer's share mTOR pathway dysfunction and neuroinflammation, and Johns Hopkins work on sulforaphane from broccoli seed extract improved brain function in a third of autistic children studied.
The real question isn't 'what disease do I have?' but 'where is the inflammation coming from?' That could be mold, metals, Lyme, leaky gut, or multiple factors stacked together. — Dr. Richard Horowitz

What these episodes have in common

Theme 1: Every episode treats inflammation as a symptom with an upstream address

The strongest agreement across all 11 conversations is structural. None of these guests treat inflammation as a thing you attack directly. They treat it as the body's response to an upstream condition, and they argue about which upstream condition matters most. Dr. Will Bulsiewicz locates it at the gut barrier, where a weakened single-cell lining activates the immune system around the clock. The compilation in It's Not Cholesterol locates it in metabolic dysfunction, with Dr. Cindy Geyer pointing out that 88% of Americans carry some degree of it and that hyperinsulinemia drives inflammation years before a diagnosis. Dr. Richard Horowitz locates it in hidden infections and toxins, and calls the alternative approach the naming and blaming game: label the disease, medicate the label, leave the driver untouched.

The practical consequence is a search order. Diet and gut barrier first, because Bulsiewicz shows the feedback loop is measured in days and the intervention is fiber. Metabolic markers second, since a fasting insulin and a C-reactive protein reading cost little and change the picture. Stress and sleep third, which is where Dr. Jenna Macciochi's self-compassion finding and Dr. Charles Brenner's circadian NAD material overlap. Hidden infection and environmental load last, once the obvious levers are pulled, which is exactly the population Horowitz sees.

Dr. Terry Wahls is the proof of concept for the whole framing. Her progressive MS was treated as irreversible until she rebuilt her diet around 20 nutrients her mitochondria needed, and went from a wheelchair to an 18-mile bike ride in ten months. The disease label stayed the same. The upstream inputs changed.

Theme 2: The nervous-system route is free, and the two Kevin Tracey episodes disagree about how much to trust it

Dr. Kevin Tracey appears twice on this list, and the two conversations are worth hearing in sequence because they pull in opposite directions. On The Ed Mylett Show he makes the maximal case: he discovered the inflammatory reflex, the vagus nerve is the brake on inflammation, an FDA-approved implant gave 75% of treatment-resistant rheumatoid arthritis patients significant relief, and bioelectronic medicine may begin replacing drugs. On 10% Happier, speaking to a meditation audience with every incentive to tell them their breathwork is fixing their immune system, he becomes markedly more careful.

There he gives the protocol (3 seconds in, 7 seconds out, six cycles a minute, 5 to 10 minutes daily) while flagging that large clinical trials on inflammation outcomes are still outstanding, that HRV has no measurement standard across devices and postures, and that raising vagal tone to the heart tells you little about the other fibers among the 200,000. The honest synthesis: the breathing practice has established cardiovascular benefit, costs nothing, and is a reasonable bet on inflammation. The wearable number people use to track it is the weak link.

Dr. Jenna Macciochi arrives at the same territory from immunology and lands a harder result: six to eight weeks of self-compassion training measurably lowered inflammatory markers in blood. Two independent disciplines converging on the nervous system as a real anti-inflammatory input is the most underrated finding across these episodes, because it is the one lever available to someone whose diet is already clean.

Theme 3: Most of these episodes argue your standard blood panel is looking in the wrong place

A measurement critique runs through the list, and it is remarkably consistent. It's Not Cholesterol makes the sharpest version: conventional panels calculate LDL and skip particle size and number, two people at LDL 130 can sit at completely different risk, and high cholesterol without inflammation may carry negligible risk while high cholesterol with elevated C-reactive protein sharply raises heart attack risk. Glucose and A1C can read clean while insulin runs ten times high. Brain Inflammation adds targets a standard panel omits entirely: homocysteine above 14 for a 50% higher Alzheimer's risk, plus vitamin D, omega-3, and perimenopausal estrogen status.

Dr. Charles Brenner extends the critique into supplement science. Blood NAD holds near 20 micromolar with age while tissue NAD in liver, muscle, brain, and cochlea declines, so the blood number that supplement marketing leans on is the one that moves least. Dr. Horowitz says the same about infection: Quest and LabCorp panels routinely miss Bartonella, so the clinical tell (migratory pain) outperforms the lab. Dr. Kevin Tracey says it about HRV.

Dr. Max Krummel supplies the reason all of this is hard. With roughly 10^11 T cells acting as sensors judging what falls in range, and every cell accumulating its own mutations until the body becomes a genetic mosaic, there is no single number that captures immune state. The workable conclusion from these 11 episodes is to combine a few cheap markers (C-reactive protein, fasting insulin, homocysteine, vitamin D, omega-3) with symptoms you can actually observe: energy, brain fog, joint pain, bloating, skin, and recovery speed.

Frequently Asked Questions

How do you reduce inflammation in the body?

Start with the gut and the metabolism. Dr. Will Bulsiewicz's case across two episodes here is that fiber-rich whole foods feed microbes that produce short-chain fatty acids, the compounds he calls the most anti-inflammatory nutrients he has encountered, and that the gut barrier holding 70% of your immune system rebuilds every 3 to 5 days. Add a metabolic check, since the Dr. Hyman compilation shows insulin resistance drives inflammation years before glucose moves. Then work the nervous system: Dr. Kevin Tracey's breathing protocol and Dr. Jenna Macciochi's self-compassion research both lower the signal telling your immune system it is in danger.

What foods reduce inflammation the fastest?

Fiber-dense plants, and beans lead the list. Dr. Will Bulsiewicz calls beans the most densely packed source of the fiber, polyphenols, and resistant starches that gut microbes ferment into acetate, propionate, and butyrate. Introduce them gradually, since feeding a weak microbiome too much at once causes gas and bloating, and he frames that as loading a bar too heavy for an injured muscle. Dr. Terry Wahls goes further with a daily structure of 9 cups of vegetables: 3 cups leafy greens, 3 cups sulfur-rich cabbage-family vegetables and onions for glutathione and NRF2 activation, and 3 cups brightly colored for carotenoids. Cooling cooked beans or potatoes creates extra resistant starch, which survives reheating.

How long does it take to reduce inflammation?

The biology moves faster than most people expect. Dr. Will Bulsiewicz says the microbiome starts reshaping within 24 hours of a dietary change and the gut barrier regenerates completely every 3 to 5 days, which puts a meaningful shift inside one week. Marker changes take longer: Dr. Jenna Macciochi cites six to eight weeks of self-compassion training to move inflammatory markers in blood, and Dr. Charles Brenner describes nicotinamide riboside trials where anti-inflammatory effects persisted three weeks after subjects stopped taking it. For structural conditions the timeline is months, as with Dr. Terry Wahls going from a wheelchair to an 18-mile bike ride across ten months.

What are the signs of chronic inflammation?

Chronic low-grade inflammation is mostly silent, which is why these episodes lean on indirect signs. Dr. Will Bulsiewicz lists fatigue, brain fog, mood changes, skin problems, and metabolic dysfunction as the common presentation of a weakened gut barrier. Dr. Mark Hyman's point about the brain is blunter: it has few ways of saying ouch, so inflammation there surfaces as depression or cognitive decline with no sensation attached. Dr. Will Bulsiewicz adds two timing clues, since the immune system runs its maintenance overnight: congestion at bedtime and next-morning soreness after training. Dr. Richard Horowitz offers the most specific tell for an infectious driver: migratory pain that moves unpredictably between joints, muscles, and nerves.

Do supplements reduce inflammation?

Some do, with the lifestyle work done first. Dr. Charles Brenner, who discovered nicotinamide riboside as an NAD precursor, cites eight randomized controlled trials showing about 1 gram daily lowers IL-6, IL-10, and other inflammatory markers, with the clearest benefit in people who already have inflammatory conditions such as COPD and long COVID. His own framing puts obesity, chronic inflammation, and poor sleep as the root causes draining tissue NAD, so exercise and weight loss come first. The Brain Inflammation episode adds a targeted case: B12, folate, and B6 improved memory and slowed brain shrinkage specifically in people with homocysteine above 14.
