- kristi f.Verified BuyerRated 5 out of 5 stars3 hours agoAmazing!
I am starting my fourth week and I seriously can't believe the difference this has made! My stomach started feeling calm right away. It has also done wonders with my constipation and bloating issues. I take one a day right before my evening meal. It is definitely working for me and I highly recommend it.
- Cynthia G.Verified BuyerRated 5 out of 5 stars1 week agoBloating reduction
I’m glad I read Dr B’s instructions on the time frame for changes. This product helps with bloating and increases abdominal comfort. Thank you Dr B for your amazing prooducts!
- Simone W.Verified BuyerRated 5 out of 5 stars2 weeks agoDefinitely works
Highly recommend - works. Just used it on a very long flight to Europe. Normally long flights cause severe bloating - not this time. I use all three products and feel that they have made a huge difference in my well-being.
Thank you for finally creating something that truly works.
- Susan D.Verified BuyerRated 5 out of 5 stars2 weeks agoBDR is the perfect partner! It is the cherry on the top of the DMN🥳
I have been taking DMN for several years now. However, my IBS continued to cause annoying symptoms. While my gut felt healthy, I had many mornings of “ gurgly” belly, uncertain if I should leave the house. I had many afternoons with brain fog. I spent so much time trying to decide what the day would look like. Constipation? Diarrhea?
I saw DMN improvement within days. I would start with one capsule in the morning and often add a second dose. I occasionally took one at bedtime if I felt bloated from the day. This amazing pill-in-pill has given me back normalcy. What a gift!
And most importantly, it has allowed me to have a normal morning routine – predictable – healthy!
I still have some difficult days when there are other interferences, like Travel, or like a cold, or like making bad food choices.
But BDR is my whipped cream and cherry!!
- Laura P.Verified BuyerRated 1 out of 5 stars2 weeks agoDidn’t order this
I don’t know why you’re sending this to me. I did not order BDR. I ordered RCE and have received NO communications for that product. Something is wrong with your system. Can you fix it?

BDR™ FAQS
You've got questions. We have answers.
ABOUT THE FORMULA
What is BDR?
BDR is a gastroenterologist-formulated, evidence-based dual-stage capsule for adults living with occasional bloating, gut discomfort, and digestive sensitivity. Two clinically studied ingredients — peppermint oil and ibSium® Probiotic — combined for the first time and delivered to different regions of the gut: fast-acting relief and lasting resilience.
How does BDR™ work?
Two ingredients, delivered in two places, at two speeds. Peppermint oil (43% Menthol) is released in the small intestine and calms spasm and discomfort, working fast. ibSium® Probiotic is released toward the colon and builds gut resilience and rhythm over weeks. A dual-stage cap-in-cap capsule delivers each ingredient where it works.
What's the evidence behind BDR™?
Both core ingredients are backed by clinical research. Peppermint oil has been studied in multiple clinical trials for gut comfort and calming spasm, and ibSium® Probiotic is a clinically studied yeast researched for its effects on bloating and regularity. BDR™ was formulated by practicing gastroenterologist Dr. Will Bulsiewicz, who set the bar at what the evidence supports.*
Read more about the science
Isn't this just peppermint oil?
Location and dose matter. Standard capsules release at one site; BDR™'s acid-resistant outer capsule targets the small intestine and pairs a second ingredient working further down. Same ingredient class, fundamentally different delivery.
Is BDR™ a probiotic?
BDR™ isn't a probiotic product. Its ibSium® Probiotic component is a clinically studied yeast, not a bacterial blend — different organism, different mechanism, different job.
How is this different from DMN®?
Different jobs. DMN® is foundational daily microbiome nutrition; BDR™ is targeted relief for when your gut needs it.
Can I take BDR™ with RCE™ and/or DMN?
Will this work with my GLP-1 medication?
BDR™ isn't formulated with GLP-1 medications specifically in mind. If you need help with occasional constipation, RCE™ was designed for exactly that - taken 20-30 minutes before your largest meal.
Usage & Results
How many should I take to start?
Start with one capsule, build to two if needed. BDR uses flexible dosing — anywhere from 1 to 6 capsules (3 x 2 capsule servings) per day, so you can scale to your symptoms. Because dosing is flexible, BDR works both as a daily routine and as something to reach for on bad gut days, after travel, or when a meal doesn't sit right.
How quickly will I feel results?
Once the capsule reaches the small intestine, fast-acting relief is on the way — that's the peppermint oil calming spasm. The probiotic side works on a longer arc: benefits build over several weeks with consistent use.*
How do I know it's working?
You may notice fast comfort early on from the peppermint oil, with more complete benefits — regularity, less bloating, better microbiome balance — building over several weeks of consistent daily use.*
Does it need to be refrigerated?
No. BDR™ is shelf-stable and doesn't need a fridge — heat doesn't damage it. If a bottle sits in a hot mailbox, the product is still fine; the inner capsule protects the probiotic.
Can I take BDR™ every day, or only when I need it?
Either way works — keep it on hand for occasional bloating, or take it daily for ongoing support. Start with one capsule and increase to two if needed.
How is this different from a probiotic I've already tried?
Most probiotics are bacteria in a standard capsule with no control over where they land. ibSium® Probiotic is a clinically studied yeast carried by an inner capsule further down the gut, closer to where it's effective.
ORDERS & SUBSCRIPTIONS
What sizes does BDR™ come in?
30-capsule and 60-capsule bottles. The 30-count is the better fit for occasional, travel, or menstrual-cycle use; the 60-count suits daily support.
What subscription options are available?
One subscription option only: monthly (every 30 days). There is no 60- or 90-day subscription for BDR™.
Can I add BDR™ to my existing DMN/RCE subscription?
If you want BDR™ delivered on the same schedule as your current subscription, it can be added to that subscription. If you want a different delivery interval, you'll need a separate BDR™ subscription — that's the only way to have two different delivery intervals.
What's your return/refund policy for BDR™?
We stand behind our science. If you’re not completely satisfied with your 38TERA® experience, we offer a 30-day money-back guarantee on your first order. To request a refund, please visit the 38TERA Returns Portal within 30 days of receiving your delivery.
