Your Questions Answered
I’ve been really intentional about supporting my gut health lately, and Biome Protect has become one of those daily wellness habits that just makes sense for me. I love that it takes a more holistic approach with a blend of prebiotics, postbiotics, polyphenols, and other gut-supportive ingredients, rather than feeling like I’m just adding another supplement to the lineup.
I’ve been mixing it into my daily routine and genuinely love knowing I’m tending to my microbiome from a few different angles. I've been thinking of it as a little daily garden tending for my gut!
Hey Kelly,
Daily garden tending for your gut is genuinely one of the most perfect descriptions of what Biome Protect is designed to do and we are absolutely using that! The Bacillus coagulans the FortiPhage™ bacteriophage prebiotic the CoreBiome® tributyrin and the polyphenol blend from pomegranate grape cranberry and blueberry each tending a completely different part of the gut ecosystem every single day is exactly the holistic multi-angle approach Chris designed it around. We love that it just makes sense to you and thank you so much for sharing!
This is an incredible product. This has worked for me when many others have not.
I have had a bulging, rock hard stomach for a long time. I had this experience once before when I had a mold infection. This time, my problem is not mold. It might be due to a drug response I had last winter. At any rate, I have had good results with Biome Protect. I added colostrum to my daily routine and it was a good thing. My problem is resolved and I am taking Biome Protect as a preventative.
Hey Rosalie,
A bulging rock hard stomach that resisted everything else and then Biome Protect plus Colostrum+ resolving it and now using both as a preventative going forward is exactly the combination Chris designed the Total Gut Reset protocol to deliver. The Bacillus coagulans the FortiPhage™ bacteriophage prebiotic the CoreBiome® tributyrin and the polyphenol blend from pomegranate grape cranberry and blueberry rebalancing the microbiome environment while the colostrum nourishes and repairs the gut lining from the other direction is such a powerful pairing. We are so glad you found what worked and thank you for sharing your story!
My husband has been on this for 2 months now and feels less bloated and more regular. Great product.
Hey Toni,
Two months of less bloating and better regularity for your husband is wonderful to hear and we are so glad it is making a real difference in his daily life! The CoreBiome® tributyrin fueling the colon cells directly plays a big role in that regularity improvement and the Bacillus coagulans the FortiPhage™ bacteriophage prebiotic and the polyphenol blend from pomegranate grape cranberry and blueberry are all working together to keep the gut environment balanced and thriving. Thank you so much for sharing on his behalf!
Living with flatulence my whole life, and the more I age the more it gets worse, I really want this product to work. So far I believe I noticed a little difference, a small improvement, i’ve been using it for a 3 weeks now and I hope it gets better.
Hey Marianna,
Three weeks in and already noticing a small improvement is a really encouraging start and we are rooting hard for things to keep shifting! The Bacillus coagulans the FortiPhage™ bacteriophage prebiotic the CoreBiome® tributyrin and the polyphenol blend from pomegranate grape cranberry and blueberry all build with consistent use and the benefits really do compound over time. Gas and flatulence are often some of the last things to fully resolve as the microbiome rebalances so hang in there and give it the full 8 to 12 weeks. We believe this is going to keep getting better for you. Thank you for sharing!
I bought the Biome Protect for my husband who has Crohn's disease, and he like it so much that I bought it for myself as well.
Hey Rachel,
This is so sweet and honestly one of our favorite kinds of reviews! The photo you sent along made us truly smile! Biome Protect was formulated with people in mind who have real and persistent gut challenges. The 4-in-1 combination tends to resonate with people who have tried everything else. We hope you and your husband both continue to feel the full benefits and thank you so much for the support. This truly means the world to us!
I have suffered with a disrupted gut for years. Probably before I even realized it. Decided to try the Bio-Avail along with the Biome Protect. It has worked great! Started to see a very noticeable improvement within the first week. I no longer suffer from the bloating after eating, The gas and belching has all but disappeared and I am only 3 weeks in with my first order. Customer for life!
Hey there,
This is amazing—thank you so much for sharing! We're thrilled to hear you're seeing such dramatic improvements in just three weeks!
The fact that you noticed a difference within the first week and it's continued to build is exactly what we love to hear. No more bloating, gas, or belching after years of suffering is life-changing, and we're so glad you gave Biome Protect a try. Benefits often continue to build over the next few months as your gut continues to heal and rebalance. Welcome to the Adapt Naturals family. We're so glad you're here, and we're honored to be part of your gut health journey.
I decided to try Biome Protect because the probiotic I had been taking for years wasn't helping me with constipation at all. I bought one package of Biome Protect and started with just one capsule instead of the recommended 2 capsules a day. I started to notice an improvement almost right away! I decided to stay with one capsule a day since my bowel movements became more regular and actually looked like the healthy bowel movement picture on the gastroenterology specialist's office chart. I never expected to see such a dramatic change in my bowel movements. Right before I finished the first package, I signed up for a subscription of one package every 2 months. I am more than satisfied with this great product!
Hi Patricia,
That's fantastic! We're so thrilled to hear about your experience with Biome Protect!
It's wonderful that you listened to your body and adjusted the dosage to what works best for you—starting with one capsule and seeing such quick, noticeable improvement is exactly the kind of result we love to hear about. And the fact that you're seeing consistently healthy bowel movements that match the gastroenterology chart? That's really encouraging!
We're so glad you found a rhythm that works perfectly for you with the subscription. Thank you for trusting Biome Protect and for sharing your story—it means the world to us. Here's to continued digestive health and feeling your best!
I started taking Biome Protect about a month ago,and I couldn’t be more pleased with it. I used to be dreading what my bm would be every day, constipation! Diarrea? Things have changed for the best, I was pleasantly surprised and shocked about a week of Biome Protect to have a normal bm. I will be forever thankful for Dr Chris Kresser
Hi Esther,
Thank you so much for sharing this wonderful experience! We're absolutely thrilled to hear that Biome Protect has made such a meaningful difference for you—and in just one week! No longer having to dread your daily digestive experience is such a huge quality of life improvement.
The Bacillus coagulans probiotic in Biome Protect, along with the tributyrin, PreforPro prebiotic, and polyphenols, work together to support gut health and healthy digestive function. It sounds like your microbiome is responding beautifully to the comprehensive 4-in-1 approach.
We're so grateful that Chris's formulation is helping you feel your best, and we appreciate you being part of the Adapt Naturals community. Reviews like yours truly inspire us! Take good care.
I feel less bloated and more energy since taking it. I also have always loved pomegranates for a million reasons and this is just one more that they help out microbiome. So cool!
Hi K,
That’s fantastic to hear! And yes—pomegranate extract is one of our favorite microbiome supporters. Its polyphenols are like fuel for beneficial bacteria. We’re thrilled to see those benefits showing up in your body!
I’ve only been using the Biome Protect for a couple weeks and I’m already seeing slight improvement in my bowel movements.
However, I noticed an empty capsule and loose powder in the bag. So I’m a bit disappointed in losing some precious product.
Hi Beverly,
Thanks so much for your review. We’re glad to hear you’re starting to see digestive improvements—even small shifts early on can signal progress! We’re sorry to hear about the capsule issue and appreciate you bringing that to our attention. If you'd like a replacement or help with this, please reach out to our support team.
Wishing you continued improvement!
A lot of gut relief so far and much healthier poop
Hi Andrew,
Thanks for sharing your experience with Biome Protect! Great to hear you're getting gut relief and seeing positive changes in your digestion already. That improved stool quality is actually one of the most common benefits our customers report, and it's a good sign that the product is working well for your microbiome.
I was surprised how noticeable the results were for me early on. I had a more stable mood even though I was in my late luteal phase, and I was feeling more energized in the mornings. I took this first thing in the morning, and I could tell fasting came more easily than it has been lately. This is probably thanks to the bioavailable butyrate they've added. How cool! As a fasting coach, I also looked into the fruit extracts to be sure those quantities wouldn't disrupt ketosis or fasting (they don't even come close).
What's more is that the new form of prebiotics they have incorporated are as effective as 10x this dose but without those pesky side effects commonly experienced, such as gas and bloating. I was able to start with a full dose on day one and no gas. That's great!
This is the first probiotic supplement I have tried that I've actually felt a noticeable difference. My bowel movements were completely normalized since I started too. I'll definitely be telling clients about this, and ordering more for myself.
Hi Marisa,
Thanks for sharing your experience with Biome Protect! It's fantastic to hear you noticed such early results with mood stability, morning energy, and easier fasting - especially as a fasting coach yourself.
The normalized bowel movements and lack of gas/bloating (even starting at full dose) are exactly what we hoped for when formulating with the specific strains and prebiotics. Your professional perspective on the product's benefits is particularly valuable.
Thanks again for your thoughtful review and we look forward to hearing about your future experience with Biome Protect!
I've been trying to think why is my skin glowing and so much clearer all of a sudden? Then I realized it's ever since I started taking biome protect! I think it's definitely helped balance out my gut micro biome because I no longer get the hormonal breakout that I always get every month and my digestion has also improved. I used to experience a little bit more bloating after certain foods and I no longer seem to have that problem so thankful for this product!
Hi Cara,
Thanks for sharing those unexpected skin benefits! It's amazing how your breakouts have cleared up - really shows that gut-skin connection in action. And less bloating is always a win!
We love when customers notice improvements beyond what they were originally looking for. The skin clearing up is a great sign that Biome Protect is helping balance your gut microbiome like it's designed to do.
I’ve struggled with gut issues for most of my life, and things got ten times worse after contracting COVID four years ago. I was extremely bloated and felt like I couldn’t eat anything without a reaction. When I say bloated, I literally looked nine months pregnant, I will attach my before and after pictures. I tried countless supplements and different probiotic brands, but nothing seemed to help. After researching new supplements, I discovered Adapt Naturals, and I can finally say that my bloating is almost gone after just a few weeks. I have much less gas, and my painful gas is completely gone. My bowel movements have become more regular (2-3 times a day, compared to 1 times before).
I also suffer from chronic fatigue, and I’ve noticed an improvement in my energy levels. I need fewer breaks throughout the day and can work longer, which was a real struggle for me before. Additionally, I feel calmer, I’m not crying as much, and I feel more emotionally balanced overall. I’ll definitely continue taking these supplements, and I can’t wait to see my progress after a few more months! I also take other Adapt Naturals supplements to support my health, including Omega, Beef Organs, and Colostrum.
Hi Skai,
Thanks for sharing your incredible gut health journey! Going from extreme bloating to finding real relief is huge. Those improvements you're seeing - reduced bloating, better digestion, more energy, and even emotional balance - really show how connected gut health is to our overall wellbeing.
After trying so many products without success, we're glad you found something that actually works. Many of our customers combine Biome Protect with Omega, Organ, and Colostrum+ like you're doing - they work really well together for comprehensive support.
Keep us posted on your continued progress! Stories like yours remind us why we do what we do.
After struggling with gut issues for years, my little girls started to struggle too. We started using Colostrum+ from Adapt for a while, and we’ve loved it! When we got the opportunity to try Biome Protect, I knew we had to try it, and I’m so happy we did. It took about 2 weeks for me to really feel it, but my digestion has greatly improved, and we didn’t get sick at all after hanging out with sick cousins a couple weeks ago! Can’t wait to see how we feel after a few months!!
Hi Carolina,
Thank you for sharing your family's journey with both Bio-Avail Colostrum+ and Biome Protect! It's wonderful to hear how these products are helping both you and your daughters with gut health and immune support.
While some people notice changes quickly, others find it takes a couple of weeks to experience the full benefits as the 4-in-1 formula works to support a healthy gut ecosystem. And it's fantastic that your immune systems stayed strong even after exposure to illness!
Please keep us posted on how you and your girls continue to feel over the coming months. Your experience could really help other families looking for natural solutions for gut health!
I’ve been trying Adapt Naturals Biome Protect, and it’s truly unlike any other gut health supplement I’ve used. Drawing on Chris Kresser’s 15 years of clinical expertise, this 4-in-1 formula combines PreforPro® prebiotic, LactoSpore® Bacillus coagulans probiotic, CoreBiome® tributyrin, and a specialized polyphenol blend for a comprehensive approach to digestive and overall health. I love that it avoids the typical side effects of fiber-based prebiotics and ensures the probiotics actually survive stomach acid to reach the intestines. Since starting Biome Protect, I’ve noticed improved digestion, more energy, clearer skin, and even better focus. Plus, it’s shelf-stable, eco-friendly, and thoroughly tested for purity, making it a product I trust and highly recommend.
Hi Melanie,
Thank you for this review of your experience with Biome Protect! We're thrilled to hear how it's improving not just your digestion, but also your energy, skin health, and mental clarity. This illustrates how supporting gut health can have wide-ranging benefits throughout the body.
You've highlighted some key points that make Biome Protect unique - particularly how we've addressed common issues with traditional gut supplements. The PreforPro® prebiotic works effectively at a much lower dose than fiber-based prebiotics, helping avoid the bloating and discomfort that many people experience. And the spore-forming LactoSpore® probiotic is specifically chosen to survive the journey through stomach acid.
Thank you for taking the time to share such detailed feedback about your experience!
I actually think I’ve seen an improvement
