"Most people are feeding themselves — but not their microbiome. DMN® was built to close that gap. I designed this formula because nothing like it existed."

Dr. Will Bulsiewicz, MD, MSCI — Board Certified Gastroenterologist

Scientists study DMN:

Your microbiome starts changing within 24 hours

An independent M-SHIME® gut-model study tracked the measurable changes that happen when you take DMN® consistently. The data speaks for itself.

View the 15-Day Microbiome Study Results ➔

Day 1Acetate ↑ from 24hrs
First fermentation begins

Resistant starch reaches your colon and bacteria begin breaking it down. SCFA production starts almost immediately.

Day 3Acetate ↑12%
Steadier energy, fewer cravings

Short-chain fatty acids begin signalling your brain and metabolism. Acetate increases 12% — your gut is making clean fuel.

Day 5Ammonium ↓11%
Less bloating, clearer head

Ammonia (a gut irritant) drops 11% as beneficial bacteria begin crowding out fermenters that cause gas and discomfort.

Day 8Propionate ↑28%
Microbiome shift underway

Beneficial bacteria populations are measurably rising. Propionate climbs 28% — gut cells are getting well-fed, digestion smooths out.

Day 15TNFα ↓ · Akkermansia ↑
Akkermansia takes charge

Your gut's guardian bacterium rises to prominence. TNFα drops — inflammation cools. This is the gut reset you've been building toward.

1 month+Long-term foundation
Deep repair and steady balance

Your microbiome enters a phase of sustained diversity. Long-term benefits — immunity, metabolism, mood — compound with consistent daily use.

†In an Independent M-SHIME® 15-day human gut-model study, DMN® supported microbial balance by increasing key short-chain fatty acids and reducing gut irritation markers. Not a human clinical trial.*

NSF Certified for Sport®. The industry's highest bar.

SIMON HILL, 38TERA® CO-FOUNDER

NSF Certified for Sport® is not a marketing badge. It is an independent certification program that tests supplements for 280+ banned substances. Every batch of DMN® is tested under this protocol — not once at launch, but every production run before anything ships.

280+ Banned Substances

280+ substances prohibited across professional and elite sport — tested per batch. WADA, NFL, MLB, NBA, and PGA compliant.

Contaminant Testing

Heavy metals, pesticides, and microbiological hazards — tested in raw materials and in the finished product before any batch is released.

Label Accuracy

Every active ingredient confirmed at the dose stated on the label — independently tested, not self-declared by the brand.

Manufacturing Audit

Facility standards independently audited: raw material sourcing, in-process controls, and finished product release protocols.

    The BEST!

    I wouldn’t start my mornings without DMN now. I felt an adjustment in just week. As someone who’s been on a gut and SIBO healing journey for some time. DMN has been a perfect addition!

    Definitely helping

    My wife's traditional GI doctor dismissed her with a IBS Diagnosis (which we do believe), recommended low FODMAP diet, and basically just said it is what it is. Never mentioned the key bit out LOWFODMAP diet is not supposed to be long term......

    We took matters into our own hands...

    Read the FUEL FIBERED book, getting the DMN, and also now getting RCE, Game changer.

    DR B's advice far exceeds anything we've gotten from years of normal healthcare advice and traditional GI doctor advice. Not once did they bring up Fiber, Diversity, etc.

    My wife, while not completely out of the woods, is doing 1000% better since we started focusing on Fiber, Diversity, and implementing DMN + RCE.... sometimes she still has bad days but at least she's doing it while eating things she enjoys again.....compared to with the GI advice she was highly limited in food and having MOSTLY bad days.

    Please if you love your wife and sick of every day being bad - read Fiber Fueled, subscribe to Dr B's advice, get DMN and RCE, and get a ton of fiber and diversity....life will be soooooooo much better

    Highly recommend!

    A friend recommended 38Tera when I mentioned I was having a lot of stomach issues. Within 2 weeks I felt a noticeable change to how I was feeling. Highly recommend!
