Your Future Self Thanks You For Finally Finding a Gut Health Formula That Works

Your gut does more than digest food. It houses 70% of your immune system, produces neurotransmitters that affect your mood, and determines whether nutrients actually reach your cells or pass through unused & wasted.

When your gut microbiome is out of balance, you feel it everywhere. The bloating after even the healthiest of meals, the brain fog that makes simple tasks feel impossible, the fatigue that coffee can't touch, and of course, the irregular bathroom visits that keep you guessing.

You've probably tried probiotics that promised everything and delivered nothing, and you're not alone. That's why Biome Protect is formulated to be the only 4-in-1 microbiome support system that replaces an entire cabinet of gut supplements with one comprehensive solution.

Here are five reasons why Biome Protect helps you finally trust your gut again:

Reason #1: The Bloating and Gas That Used To Rule Your Days is GONE

Finally feel free eating again! Wake up without that tight, distended feeling, eat lunch and button your pants without discomfort, and make it through dinner with friends without wondering if your stomach will embarrass you.

By day three or four, you notice something different. By week two, you start trusting your body at meals again. By day 90, your gut health & your relationship with food will be completely transformed.

Biome Protect delivers a spore-forming probiotic called LactoSpore® that survives your stomach acid and actually reaches your intestines alive. Most probiotics die before they do anything. This one arrives intact, produces lactic acid that crowds out gas-producing bacteria, and starts restoring balance within days.

This isn't another fragile probiotic that requires refrigeration and still shows up dead on arrival. This is a shelf-stable, clinically studied strain that reduced bloating scores by over 5 points in just four weeks during clinical trials. That's why customers notice their guts getting quieter, not louder.

Real Customer Review:

"I've been taking this probiotic for a little over a month, I take it in the morning on an empty stomach and the gas and bloating I usually experience daily has decreased dramatically! I have more confidence in social situations and in my body!" — Dana C.

Reason #2: The Mental Clarity You Weren't Expecting (When Your Gut Heals, Your Brain Follows)

You're buying Biome Protect for your digestion, but within days, your brain fog lifts, your thoughts connect faster, and you start to feel like yourself again.

Your partner notices before you do. "You seem lighter," they say. And you realize they're right.

The same compounds that support your gut also support your brain. Your gut produces over 90% of your body's serotonin and communicates directly with your brain through the vagus nerve. When your microbiome is balanced and your gut barrier is intact, fewer toxins leak into your bloodstream and fewer signals tell your brain something is wrong.

When your gut has the support it needs, you don't just digest better, you think better too.

Real Customer Review:

"Biome Protect has changed my life! My longtime constipation is GONE. I'm digesting my food better. I have more energy. My mood is better, and I'd even say I have less anxiety. If I could only choose one supplement, this would be it!" — Jill M.

Reason #3: One Formula Replaces the Cabinet Full of Supplements That Didn't Work (The 4-in-1 Solution for People Who've Tried Everything)

Remember when one probiotic seemed like enough? Then you added digestive enzymes, then a prebiotic fiber that made you more bloated than before, and finally tried butyrate supplements that smelled terrible and upset your stomach.

Biome Protect ends that cycle, with one formula containing all four mechanisms your microbiome needs.

Some customers tell us they've cleared out entire shelves of gut supplements after switching. Most report that the simplicity alone removes a layer of daily stress, taking two capsules because it works, not because they're managing a complicated regimen.

Biome Protect combines what moves the needle: a postbiotic (tributyrin) that feeds your gut lining directly, a probiotic (Bacillus coagulans) that survives to do its job, bacteriophages that selectively reduce problem bacteria, and polyphenols that nourish beneficial strains. Four categories in one bottle.

This is real gut support, not a shelf full of half-measures that never added up.

Real Customer Review:

"As someone who used [competitor] probiotic/prebiotic for several years with only moderate success, I'm genuinely impressed by how much more effective Biome Protect has been for me. The difference is clear." — Jim A.

Reason #4: Regularity That Stays Regular (Your Digestion Working Like It Should)

You deserve to know what to expect from your body instead of planning your day around uncertain bathroom trips.

Your elimination pattern starts working the way it should, you can actually stick to a morning routine, and you stop thinking about your bathroom schedule because there's nothing to think about.

One customer who struggled with slow transit for years reported daily bowel movements within the first month. Another described finally reaching "a normal 4 on the Bristol chart" after years of inconsistency.

CoreBiome® tributyrin delivers butyrate directly to your colon cells, the preferred fuel source for the cells that line your intestinal wall. When those cells are nourished, they function properly. Motility normalizes, the gut barrier strengthens, and things finally move the way they're supposed to.

Some notice improvements within the first week, but the real shift typically emerges by week four to six as these compounds build up and your microbiome rebalances.

Real Customer Review:

"For me, Biome Protect is the supplement that has given me the most benefits for my digestive system, from digestion to elimination, in such a short time. I've always had constipation problems, bowel movements 2-3 times a week. I now have bowel movements every day, no more eczema, no more fatigue, no more belching." — Christiane P.

Reason #5: 4 Clinical-Dose Ingredients Beat 4 Separate Bottles (The Formula Functional Medicine Practitioners Choose)

We know tributyrin supports gut barrier integrity, Bacillus coagulans survive stomach acid, and polyphenols feed beneficial bacteria…

But most gut health products fail before you open the bottle. They use generic ingredients at doses too low to be effective, hide behind "proprietary blends" that obscure how little you're getting, or require refrigeration because their probiotics can't survive room temperature.

Then there are products that cause more bloating than they solve, because fiber-based prebiotics feed everything in your gut, including the bad bacteria that causes your problems.

Biome Protect delivers clinical doses of name-brand ingredients at the amounts that matter:

• 300mg CoreBiome® Tributyrin – The postbiotic that delivers butyrate directly to your colon, bypassing the absorption problems of standard butyrate supplements
• 2 Billion CFU LactoSpore® Bacillus coagulans – The spore-forming probiotic clinically shown to reduce bloating and gas, shelf-stable without refrigeration
• 15mg FortiPhage™ Bacteriophage Blend – Precision prebiotics that selectively reduce problem bacteria without causing bloating, unlike fiber-based alternatives
• 200mg Polyphenol Blend – Pomegranate, grape, blueberry, and cranberry extracts that nourish Akkermansia and other beneficial strains

These aren't random amounts. These are the doses backed by research. And these aren't generic ingredients. They're name-brand, clinically studied forms with documented results.

If you bought these four categories separately at effective doses, you'd spend over $120 monthly managing four different bottles with four different dosing schedules.

This formula came from 15 years of clinical practice. It's what worked for thousands of patients when generic probiotics didn't.

Real Customer Review:

"I've tried other GI products but didn't really notice anything. So I was reluctant to try this product but I did. Game changer! I'm very happy with it." — Michael D.

Why I Created Biome Protect

Most gut supplements are created by marketers who've never treated a single patient with digestive issues.

They see "probiotics are trending" and throw together a formula with the cheapest strains at the highest CFU count they can fit on a label. The person who "formulated" it has never watched someone avoid dinner parties because they didn't know how their stomach would behave. They've never seen a patient get worse on probiotics because no one addressed their barrier first.

They're optimizing for impressive label claims, not your actual relief.

I created Biome Protect because I was tired of watching my patients cycle through probiotics that made things worse. After 15 years in clinical practice, I understood something most supplement companies don't: you can't probiotic your way out of a damaged gut barrier. You have to address the barrier, clear space for beneficial bacteria, seed with strains that actually survive, and feed what grows. Not one of these. All of them, together.

That's not a marketing concept. That's what I learned from treating thousands of real patients who had tried everything and were ready to give up. It's also what I learned from being one of those patients myself, two decades ago, when I was sick enough to see over 30 doctors before finding my way back to health.

My background:
• Co-Founder, California Center for Functional Medicine
• Founder, Kresser Institute for Functional and Evolutionary Medicine
• Trained 3,000+ functional medicine practitioners in 50+ countries
• New York Times bestselling author (The Paleo Cure, Unconventional Medicine)
• 15+ years clinical experience treating digestive disorders
Featured on Joe Rogan Experience (5x), Time, The Atlantic, NPR

I've sat across from thousands of people who felt exactly like you do right now. Bloated. Exhausted. Frustrated. Wondering why nothing works when they've tried so hard.

Biome Protect exists because I needed it to exist. For my patients. For the practitioners I've trained who kept asking what I recommended. For everyone still stuck in the cycle of trying one more thing and hoping it finally works.

Your Questions Answered

Most probiotics die in stomach acid before reaching your intestines. Biome Protect uses LactoSpore®, a spore-forming probiotic that survives stomach acid and arrives intact. Plus, it's a 4-in-1 formula that includes a postbiotic (tributyrin), bacteriophages, and polyphenols—addressing multiple gut health mechanisms that single-ingredient probiotics can't.

Different benefits emerge at different times:
• Reduced bloating and gas: Within the first week for most people
• Mental clarity improvements: 2-3 weeks
• Regularity normalization: 4-6 weeks
• Full digestive transformation: By week 6-8

Most customers notice some benefits within the first week, with continued improvement over 2-3 months.

No. Unlike fiber-based prebiotics that feed everything in your gut (including problem bacteria), Biome Protect uses bacteriophages that selectively target problem bacteria without causing bloating. The polyphenols specifically nourish beneficial strains like Akkermansia.

No. Biome Protect uses shelf-stable, spore-forming probiotics that don't require refrigeration. This is a key advantage over many probiotics that require cold storage and often arrive dead on arrival.

Yes. Biome Protect is generally safe to combine with most supplements. However, if you're taking prescription medications, especially antibiotics, we recommend consulting your healthcare provider.

Try Biome Protect for 90 days. If you don't experience less bloating, better regularity, clearer thinking, or any of the benefits we've described, we'll refund every penny. Keep the product. No returns needed. No questions asked.
