"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.

    Perfect for long trips

    After Covid, I found I was not traveling nearly so often. As a senior, the convenience of these sachets is a great way to pack. Worth the price to continue my gut health regimen away from home.
