"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.

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.

    Just took the travel pack on an international trip!

    These individual servings of DMN recently saved me on an international trip for 2 weeks! So easy to pack and continue my use of DMN while away from the comforts of home. I'm definitely keeping a pack on hand for any trips away from home.

    Thankful for DMN

    I wasn't having any major bowel movement issues. But, at 66 I know my gut is struggling to maintain its' equilibrium. Good gut good overall health! I have been using DMN for 2 months and it has given me back the confidence in my digestion, that I can have an off day of eating and if I take this every morning, my gut is going to be fine. Consistent bowel movement and easy passing, love it!!

    The Best!

    I've been taking DMN for about a month now and I'm pleasantly surprised at how quickly my gut settled down. I'd been taking Omeprazole for many years, switched to Famotidine, and now I'm ready to stop taking Famotidine because my gut feels so much calmer with DMN. I've experienced much less gas and bloating and am now eating foods that had been too acidic (like fresh tomatoes) for my GI tract to tolerate.
