Dr. Will Bulsiewicz
Why Dr B recommends thisBoard-Certified Gastroenterologist · NYT Bestselling Author of Fiber Fueled

"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

15 Day Microbiome Study

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.*

Tested. Certified. Trusted.

Co-Founder Simon Hill explains the importance of why every batch is third-party tested and what's on the label is what's in the product—nothing more.

    Life Changer

    I am an original 38TERA subscriber and can honestly say this fine product has been a life changer for me. Poor Gut Health had always dictated my daily life activities. Since taking a teaspoon of 38TERA a day, every day, my world has opened up allowing me to get out and about and eat well without crippling IBS issues. Thank you 38TERA for giving me back my life.

    Gently healing my gut and nourishing my microbiome

    Generally, within 15 - 20 minutes after waking, I heat up some water and have 2 teaspoons of 38TERA. It makes us well and goes down easily without chewy clumps. I like the taste, especially compared to the plain acacia fiber or psyllium husk I previously took.

    I drink this as a foundation to nourish and help wake up my gut and micro biome. I appreciate that it has multiple prebiotics in it.
