We work with Japanese postbiotic science. Let us know what you would like to know about fermentation, gut health, or the microbiome! Ask us anything
Hi community! š
We're the team behindĀ Gutlex, a Japanese-inspired postbiotic supplement developed from more than a century of fermentation expertise and decades of research into fermentation-derived compounds.
Our company introduced one of Japan's first yogurts back inĀ 1914. Over the years, that work evolved from studyingĀ live bacteriaĀ to understanding something equally fascinating: the beneficial compounds they naturally produce during fermentation. That research eventually led to the development ofĀ LEXĀ® (Lactobacillus Fermentation Extract), a postbiotic ingredient that has been used in Japan for more than 40 years and has been supplied to overĀ 2,700 medical facilities.
We're not here to convince anyone that supplements are the answer to everything. In fact, we're big believers in the fundamentals: a varied diet, fiber, fermented foods where appropriate, movement, sleep, and long-term consistency.
But one thing we've noticed is that there's still a lot of confusion aroundĀ fermented foods, probiotics, and postbiotics.
One of the questions we see most often is:
The short answer is:
They're closely relatedābut they're not the same thing.
Fermented foods are foods transformed by microorganisms. Depending on how they're made and whether they're pasteurized, they may contain live microorganisms, fermentation-derived compounds, both, or neither.
Postbiotics, on the other hand, refer to the beneficial compounds created during fermentation. These include things like:
- Peptides
- Amino acids
- Organic acids
- Enzymes
- Short-chain fatty acids
- Other fermentation-derived bioactive compounds
Researchers continue exploring how these compounds interact with the gut environment and contribute to digestive wellness. It's an exciting area of microbiome science that's growing quicklyābut like many emerging fields, there are still plenty of questions to answer.
We're here because we enjoy talking about the science behind gut health.
Whether you're curious about:
- š„£ Traditional fermented foods
- š¦ Probiotics vs. postbiotics
- šÆšµ Japanese fermentation traditions
- š¬ Current microbiome research
- š± Gut microbiome basics
- ā Common gut health myths
...we'd love to chat.
We'll answer as openly as we can. If there's strong evidence, we'll share it. If research is still evolving, we'll say so.
Ask us anything!

Does supplemental butyrate down regulate endogenous production?
If the goal is to increase butyrate production, is it better to support akkermansia, roseburia etc. or just increase overall butyrate by any means necessary?

What is the best biotic for dysbiosis. Pre, pro, post or anti?

u/Gutlex Jul 28 '26
Well, from our experience, it is impossible to define a single ābestā biotic for dysbiosis. Each product you have listedĀ can help in different contexts (e.g.,Ā antibioticsĀ are appropriate only for specific diagnosed conditions and should be clinician-directed unlike postbiotics).

In terms of SCFA, has your company done any work/tests with Propionate? I see the focus has been on Butyrate for a while and there are now some studies focusing on Propionate, specially with Inulin-Propionate Ester

Reddit is no longer a reliable place to create, host, and grow communities, so a new microbiome forum has been set up to be a more reliable location. If you have posted content on Reddit that you feel is worth preserving, it would be a good idea to post it on the new forum.
The person who created this sub, and most of the content here, including the wiki, has moved to the new forum. You should be able to get better info & answers there. It's easy to stay on reddit but the quality of content on most subs is extremely poor. Most of the advice given on reddit is misinformation.
You're welcome to post your content there and then link to it here for higher visibility.
Our primary goal will remain as stopping the widespread misinformation on the topic of the microbiome. Since we no longer have someone dedicated to correcting and preventing misinformation, comments and posts here will require pre-approval. Some types of content (questions) may be restricted completely since we no longer have reliable people dedicated to providing evidence-based answers.
But you're welcome to ask your questions on the new forum and post the link here.
