After trying everything, here's what finally works.

You've been let down before. Biome Protect has all four elements your gut needs—not just one or two. Prebiotics, probiotics, postbiotics, polyphenols. Research-backed and complete.

Here's what makes it different:

1. FortiPhage™ prebiotic (15mg vs. grams of fiber) - No bloating

2. LactoSpore® probiotic (spore-forming) - Survives stomach acid

3. CoreBiome® butyrate (tributyrin) - Reaches your colon intact

4. Polyphenol blend (4 sources) - Protects and nourishes

Your search ends here. Chris Kresser spent 15 years in clinical practice treating patients with your exact struggles. This formula is the result of that experience—everything you need, nothing you don't.

You're safe now.

Here's When to Expect What

Week 1

Week 1

Your microbiome starts shifting. The probiotic reaches your intestines. Some people notice slight changes; most don't feel much yet. This is completely normal.

Week 2-4

Week 2-4

The most common window for noticeable change, based on patterns across 376 reviews. Less bloat after meals. More predictable mornings. Regularity sets in.

Week 6-8

Week 6-8

The shift compounds. Energy often follows gut improvement. Skin may clear. Some customers notice mood and mental clarity changes here.

Week 12+

Week 12+

The microbiome adapts slowly. By three months of consistent use, you've established the baseline most people come for — and stay for.

NOURISH YOUR MICROBIOME

Your Good Bacteria, Finally Thriving

FortiPhage™ and Bacillus coagulans work together to promote beneficial bacteria growth while reducing harmful microbes.

FORTIFY YOUR DEFENSES

YOUR DIGESTION, WORKING RIGHT

No More Bloating. No More Guessing.

Our 4-in-1 blend supports gut barrier function, reducing bloating, gas, and digestive discomfort.

YOUR MIND, CLEAR AGAIN

Think Clearly. Feel Like Yourself.

Butyrate and polyphenols from cranberry, blueberry, pomegranate, and grape support cognitive function and mood.

Your Questions Answered

Most probiotics only contain one of the four things your gut actually needs: the bacteria themselves. Biome Protect contains all four — prebiotic, probiotic, postbiotic butyrate, and polyphenols — at clinical doses. If single-strain probiotics haven't worked for you, the missing pieces are usually why. And if ours doesn't work either, we refund you — that's what the 30-day outcome guarantee is for.

Honest answer: most customers notice meaningful change between week 2 and week 4. A minority feel something in the first week. A minority need 6-8 weeks. If you've had gut issues for years, expect to need the full 30 days before judging. Our guarantee is built around that timeline — if you're not noticeably less bloated by day 30, we refund you.

Take 2 capsules daily, preferably with a meal. For best results, take consistently every day. Consistency matters more than timing — people who take it sporadically often report no results, while those who take it every day typically notice changes within 2-4 weeks.

Yes. Biome Protect is designed to complement other supplements, including other probiotic strains. Many customers stack it with their existing routine. If you're on blood thinners, prescription medication, or other therapeutic regimens, consult your healthcare provider before starting any new supplement.

No. The Bacillus coagulans we use is spore-forming — it stays dormant through stomach acid and only activates once it reaches your intestines. No refrigeration required. Keep it in your bag, your car, on the counter. Travel with it.

Take Biome Protect daily for 30 days. If you're not noticeably less bloated, more regular, or generally feeling better, email us any time within 90 days of purchase. We refund your full order — shipping included. No return required. This isn't a gotcha policy. If it didn't work for you, you shouldn't pay for it.

Yes, Biome Protect is formulated for safe, long-term, daily use. The ingredients are naturally occurring compounds that support overall gut health and wellness. Most customers take it indefinitely as part of their daily routine.

If you are pregnant, nursing, or taking blood thinners or anti-coagulant medications, please consult with your healthcare provider before using Biome Protect.

Good For You—And the Planet

You can't have healthy humans without a healthy planet. That's why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They're made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They're printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin!

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!
