Methanogens: The Bloating Root Cause You Haven’t Heard of (and a New Solution for SIBO)


Bloating… that enormous feeling of pressure like someone just blew up your abdomen with an air pump… and now your pants have shrunk two sizes.

Or maybe it’s that feeling of fullness like you’re dragging around an extra tire everywhere you go.

If you’re like millions of other people, you can relate.

For some people, this is an all-day problem that starts the moment they wake up and gradually gets worse throughout the day.

For others, it comes and goes – maybe related to a food trigger, or maybe with no rhyme or reason.

And along with the bloating comes the “C” word… constipation, meaning three or fewer trips to the restroom in a week..

Yet others have the opposite problem – diarrhea that strikes soon after a meal and leaves them scrambling to find the closest bathroom.

Is Leaky Gut Making You Sicker?


When Nothing Works

If you’re struggling with bloating, constipation, and/or diarrhea, you’ve probably tried all the advice…

Your mom’s advice was to eat plenty of fiber and drink more water. (That just made the bloating worse!)

A friend shared that a daily dose of probiotics has now made her “regular.” (Sure probiotics are great, but they didn’t help with the bloating…)

And when you finally decided to ask your doctor, he replied by asking how well you were handling stress and offered you an antidepressant.

While a healthy gut, a diverse microbiome, and learning to better manage stress are all positive changes, if you’re still struggling with severe bloating, they aren’t enough.

Is Bloating Really a Big Deal?

If you’re debating whether bloating is really such a big deal, consider these statistics:

Why You’re Still Bloated

So what’s behind this bloating and why is it so impossible to get rid of? The answer may surprise you…

It’s possible your bloating is caused by methane. Yes, we’re talking CH4, otherwise known by chemists as a colorless, odorless, volatile inert gas.

Methane is the main component of the natural gas you might use to power your stove or furnace.

But, humans can also produce methane in their intestines through a process called methanogenesis. And when this occurs, the result can be really uncomfortable gas and bloating.

Methanogenesis depends on the presence of a special type of bacteria in the colon called methanogens.

What Are Methanogens?

Our gut is home to about 100 trillion bacteria, nearly all of which reside in the colon. These bacteria play an important role in both our digestive and overall health. Methanogens are just one type of bacteria that can live in your gut.

Methanogens are primitive single-celled “bugs” from the domain Archaea. And while they are considered an ancient group of organisms, they still thrive today. In fact, archaea are found in every habitat where anaerobic biodegradation of organic compounds occur (yes, we’re talking about poop), including the human and animal intestinal tracts.

Methanogens in humans are limited to three types:

If you have methanogens living in your gut, you’re potentially a “methane-producer.”

In the human population, individuals can be classified as methane producers or non-producers. While some studies estimate that 35% of the Western population is considered methane producers, other studies report that the range may be somewhere between 30-62%.

What Causes Methanogenesis?

So here’s how it works. When we consume a type of carbohydrates called polysaccharides (such as in starches and grains – even gluten-free), the bacteria in the colon help to break down these molecules through a process called anaerobic metabolism resulting in H2 (hydrogen) and CO2 (carbon dioxide).

Next, one of two processes can take place.

The first involves sulfate-reducing bacteria who use the hydrogen to reduce sulfate to sulfide, which are then eliminated in the stool.

The second involves methanogens, through the process of methanogenesis, who feed on the hydrogen to form CH4 (methane) at a 4:1 conversion rate – meaning that for every 4 atoms of hydrogen consumed, one molecule of methane is formed. The methane can then be eliminated through the stool, or it can be absorbed via the circulatory system and exhaled through the breath.

Methanogenesis is not a new concept. For years, this process has been recognized in the agricultural world. Livestock studies that have found ruminant animals (e.g. animals who have stomachs divided into four sections, such as cattle) produce high amounts of methane due to a diet heavy in polysaccharides.

Does It Matter If You’re a Methane Producer?

While it is normal and healthy to have a diverse bacteria in your colon – including the presence of methanogens – if you’re primarily a methane-producer, it can help to explain why you struggle with bloating.

  • Methane producers suffer more frequently from bloating than non-producers
  • Methane producers also suffer more frequently with abdominal pain and gas
  • Methane acts as a paralytic to slow down gastrointestinal transit time

(Specifically, methane slows down small intestine transit time by 59%!)

And if you’re struggling with constipation or maintaining a healthy weight?

  • In those reporting constipation, higher amounts of M. smithii have been found
  • The amount of M. smithii inversely correlates to stool frequency
  • Research studies have proposed that the presence of M. smithii also increases caloric absorption because of its effect on metabolism
  • Other studies have suggested that methane-producers have reduced postprandial serotonin levels, which can also affect intestinal transit

Can’t I Just Change My Diet?

Short answer: yes.

The Specific Carbohydrate Diet eliminates harder-to-digest polysaccharides.

Eliminating polysaccharides – alongside eating nourishing foods like bone broth and 24-hour yogurt – can alleviate symptoms and promote healing.

But that’s not the whole problem – here is the longer answer.

When Diet Isn’t Enough

Although bacteria are present throughout the entire digestive system, the majority of bacteria belongs in the colon. For example, the typical stomach is host to 101 to 103 colony-forming units per aspirate, whereas the colon is host to 1011 to 1012 colony-forming units per stool.

Between the stomach and colon lies the small intestine, which normally should contain only trace amounts of bacteria and therefore has been described as “relatively sterile.”

However, we now realize that it is possible for increased numbers of bacteria to build up in the small intestine, resulting in a condition called Small Intestine Bacterial Overgrowth, or SIBO.

This is where the issue lies: an overgrowth of methanogens in the small intestine.

The small intestine is where those pesky methane bugs can really wreak havoc on your digestive system.

What Causes SIBO?

But how does this bacteria end up in the small intestine if it’s not meant to be there in the first place?

Researchers believe that any type of “shock” to your digestive system – such as stress, being sick, food poisoning, or taking antibiotics – can result in bacteria growing where it shouldn’t, e.g. the small intestine.

The bacteria overgrowth can cause an excessive amount of both methane and hydrogen production in the small intestine, where it doesn’t belong.

In general, an excess of hydrogen production is associated with diarrhea-dominant SIBO and an excess of methane is associated with constipation-dominant SIBO. And some people have an excess of both gases.

Small intestine bacterial overgrowth has been linked to a growing number of conditions and risk factors. These include just about any condition affecting digestion or the digestive system, along with multiple other systemic conditions including:

  • diabetes
  • liver disease
  • kidney disease
  • pancreatitis
  • autoimmune disease
  • neurological conditions
  • traumatic injuries
  • catastrophic illnesses, and more.

In fact, it is now recognized that just a single episode of gastroenteritis or food poisoning can trigger small intestine bacterial overgrowth.

How Do I Know If I Have SIBO?

Just as each person’s gut microbiome is entirely unique to them, each case of SIBO is 100% unique to the person who has it. No two cases of SIBO are exactly alike – making it hard to test for accurately, and even harder to treat.

The gold standard for determining the presence of methane in the small intestine – one of two excess gases produced with SIBO – is via an invasive test. A scope is passed via the mouth, through the stomach and into the second half of the small intestine (called the jejunum) where an aspirate is collected and then analyzed.

The threshold for the presence of small intestine bacteria has been considered 105 or greater colony-forming units per gram of jejunal aspirate, although now the consensus is that 103 or higher is clinically significant.

Unfortunately, the reality is that such an invasive test is not widely available and so the more common tool to measure small intestine bacteria is via the breath test.

Breath tests work by measuring the levels of hydrogen and methane produced as carbohydrates are digested, as an indirect reflection of the bacteria present in the small intestine.

However, breath tests are not 100% reliable. While methane producers generally exhale between 20-50% of the methane via breath, the exact threshold for measuring methane has been debated. But, methane producers generally have a concentration of 108 or higher of methane per gram of stool.

This means that an absence of methane in the breath does not necessarily mean an absence of methanogenic flora in the small intestine.

On the contrary, varying amounts of methanogens are present in the vast majority of a healthy adult’s gut, almost universally.

To sum it up: even if you’ve had a negative breath test for SIBO, an overgrowth of methanogens in your small intestines could be causing symptoms.

Traditional SIBO Treatments

So how do you get rid of the excess methane in your small intestine so your life can get back to normal?

Well, that’s a tricky problem.

Traditional SIBO treatments work in 1 of 2 ways:

  • Starve the bacterial overgrowth, so symptoms subside
  • Try to obliterate the overgrowth with antibiotics

If you have a positive breath test for either methane or hydrogen, your doctor might suggest a couple of antibiotics – Rifaximin and Neomycin – which are poorly absorbed systemically and therefore work primarily in the lumen of the intestine.

But there’s a catch.

Technically, Rifaximin is only approved for those who have diarrhea-predominant symptoms (which means they’re more likely to have an abundance of hydrogen-producing bacteria). And in those individuals, it only works for about 41% of people. (This means it will likely help even less for those whose problem is constipation.)

Since we know that methane overgrowth is associated primarily with constipation-dominant SIBO, a drug that works primarily for those with diarrhea suggests that Rifaximin isn’t as effective at killing an overgrowth of methanogens.

For reasons that are not fully understood, there does seem to be some benefit to using Rifaximin combined with Neomycin, but even then the efficacy is poor.

These methods both work for some people (it goes back to each case of SIBO being unique) – but they don’t work for everyone.

And since Jordan and I were “Tough Cases” ourselves, we really empathize with these people.

They’re following a really restrictive diet (sometimes even an elemental diet with NO solid food for weeks at a time). They’ve taken powerful, expensive, and potentially dangerous drugs.

And they still aren’t getting better (or they get better for a month or two, only to have their symptoms come back worse than before).

Do We Need a New Way to Treat SIBO?

While SIBO is a relatively new diagnosis, understanding of the process of methanogenesis has existed for decades.

In fact, methanogenesis (and how to reduce it) has already been studied exhaustively in the agricultural world. This is because the production of excessive methane gas by cattle can actually impact the atmosphere.

dairy cows

(This is where things get exciting…)

Because it means there is a time-tested and science-backed way to treat excess methane in the gut caused by SIBO – other than just drastically modifying the diet.

This idea was first explored by Dr. Kenneth Brown – a board-certified gastroenterologist and clinical researcher.

Instead of trying to starve the bacteria out or obliterate them with antibiotics – Dr. Brown wanted to interrupt the process of methanogenesis.

Interrupting Methanogenesis

Using research from agricultural and gastroenterological studies, Dr. Brown identified 3 ingredients that disrupt methanogenesis:

  1. M. balsamea Wild Extract – Better known as peppermint, this ingredient has long been recognized by natural healers and scientists as a soothing agent to calm down digestive distress. Studies also show that a sustained release in the small intestine can provide rapid relief of abdominal discomfort.
  2. Quebracho – This type of flavonoid tannin has two functions.The first is to soak up hydrogen (important as methanogenesis depends on hydrogen availability to produce methane). Secondly, it works on the lipid bilayers of bacteria (meaning it weakens the cell wall of the archaea methanogens responsible for methanogenesis).
  3. Conker Tree – This is another type of flavonoid saponin (also known as horse chestnut). This ingredient acts as an antimicrobial and continues the work of the quebracho by binding the reductase enzyme in the weakened archaea to stop the cycle of methane production. In addition, saponins are also known to promote intestinal motility.

Eventually, Dr. Brown found the ideal ratio and forms of each ingredient and combined it into one supplement – called Atrantil.

A double-blind study was conducted to determine the efficacy of Atrantil. In this study, it was found that Atrantil was 88% effective in reducing the symptoms of bloating, constipation, and abdominal discomfort.

Then, in an open-label retrospective study, patients who had failed at least four other treatment options before trying Atrantil were reviewed. This study found that Atrantil offered an 80% efficacy in relieving these same symptoms even for “Tough Cases.”

So Can I Eat Whatever I Want?

I know what you might be thinking right now – does this mean I don’t need to follow a restricted diet any more even though I have SIBO? I can just take a supplement?

Definitely not.

Finding and following your own customized diet is critical to the success of any supplement.

You can’t “out-supplement” the wrong diet.

If you don’t have your diet dialed in to your needs, no supplement will help.

(If you need help finding the customized diet that supports you, make sure you join our free webinar here.)

But for those who already know what foods do and don’t work for you, are working with a great practitioner, have your stress well-managed, and are STILL dealing with SIBO symptoms, take note. This supplement might be something to try.

Is This the Solution to SIBO?

For some people, changing your diet is all you need to feel good again.

Others we’ve worked with have had relief from SIBO after a course of antibiotics or herbal treatments.

More often, though, we hear from people who struggle for years with SIBO symptoms – and nothing works long-term.

Jordan and I are passionate about sharing what works with our community – and after hearing from so many of you about your success with Atrantil, we had to learn more.

Our conclusion? If you can’t get a handle on your SIBO symptoms, you need to give Atrantil a try.

For some people, we’ve seen it give relief of major symptoms in just a few hours.

For the “Tough Cases” we work with, it can take longer to see results – up to a few weeks at the higher dose (two pills up to three times a day). You might also experience some die-off symptoms – but this is actually a good sign as it means the methane cycle is being disrupted. Staying well-hydrated and getting plenty of rest can help during this time.

We are dedicated to only sharing the best supplements with you – and we’re excited to add Atrantil to the list of supplements we believe really help people.

    The first time I tried atrantril it did help me somewhat but I had sibo for awhile had took 2 round’s of xfaxin and did me no good at all then tried this but some relief well then I seen hostlic doctor instead I had more issues going on than I thought I had parasites Candida and sibo and my immune system compromised and my gut was 80percent leaking unfortunately I had to treat leaky gut first while treating the rest 4 months later my immune system was lifted all I had left was sibo so another 6 months on a different protocol with no probiotics just berberine allimax and need plus oil of oregano and low carb diet I got my methane number’s down to a 7 8 and 9 fluctuating so then I tried atrantril again with the other herbals and still the diet now I’m just taking atrantril with vitamin c tabs and nac for liver and digestive enzymes and diet. I’m doing great going to bathroom these days no bloating at all I pray someday I can end this sibo for good.i have faith in God that I will.i really miss a least having ice cream someday yes will stay with atrantril and see what happens I hope it’s okay to use zinc with carsinine and l glutime with this to heal my gut and no I don’t use probiotics ty I get good relief from this but if I eat any sweets I get a little bit of hives so I avoid them .I can at least say I don’t get them anywhere near what I use to but that can be caused by leaky gut still there

    Really good article.

    What about the opposite case? I just got results back from uBiome Clinical, indicating I have low M. Smithii – the methanogen referred to in this piece.

    As I understand it, the role of M. Smithii is to consume hydrogen byproducts produced by other bacteria. Therefore, lower M. Smithii means higher hydrogen levels in the gut, which is associated with lower fermentation in gut and a decrease in the ability for the body to absorb nutrients and lower weight (of which I have both).

    I’ve been diagnosed with hydrogen-dominant SIBO, and the first round of Rifaxmin, as well as a second round of herbal antibiotics, haven’t changed my numbers one bit. Still high in hydrogen levels (methane levels are low, which also is consistent with low M. Smithii).

    Is there a probiotic supplement or something I can take to INCREASE the levels of M. Smithii, which may be the linchpin to decrease the hydrogen observed in both breath tests. The high hydrogen levels are the cause or associated with the pain and IBS-like symptoms.

    I am on day 3 of atrantil for sibo extreme bloat. I am having a weird reaction since the first day, continuing all the other days. I am getting ear aches and ear pressure. The thing is,
    I have had lyme disease, which is mostly under control now, and I remember the ear aches and ear pressure from the early days of lyme. So it seems to me that possibly the atrantil is causing a die off of the lyme, or else it is causing a problem, I am not sure. I do feel a decrease in bloating which is amazing. I took 2 pills 3X a day the first day, and then because of the ear aches I took 2 2X a day on day 2 and three. This morning after taking a break from the atrantil ( I waited till lunch to have it) the bloating increased and the earaches got better. then when I took them at lunch and dinner, the bloating decreased and the earaches got worse. I emailed atrantil and they said ear ache is not a common die off symptom. So I am not sure what this is doing to me. I am happy it is helping with the bloat and I hope this ear stuff passes quickly, but if it continues I cannot take it. I am not sure if it is causing the lyme to die off and this will actually clear that for me too eventually, or if it could be causing smething to flare? any thoughts on this? the earaches really hurt and I have not had ear aches in years, just since starting this.

      Hi Kate – interesting for sure. Can you try adjusting your atrantil dose just to see if that changes anything? Is there anything in atrantil that you are allergic to? Earaches are not a common die off symptom, so it is likely something else. Maybe try adjusting HEN you take it as well and see if that helps.

    If I read correctly it sounds like Atrantil is effective at treating the symptoms but doesn’t actually deal with the root cause of SIBO by eliminating the bacteria in the small intestine. Correct?

    Hi, I have Lyme disease, fibromyalgia, SIBO/constpation, and joint degeneration (2 total hip replacements at a young age) caused by SIBO.. My ND said it is very hard to get SIBO gone for good when you have chronic Lyme. True! Currently on Xifaxin and neomycin protocol with guar gum, recommended by Dr. Pimental and Chris Kressor (good interview on Chris’s site). They tell their patients to take guar gum and eat some foods that make the bacteria you want to kill active. Otherwise it hides until the threat is gone and than you have SIBO again. Also treat for biofilms. This is something you do in a Lyme protocol. Biofilms are a tough shell or covering the bacteria make to shield themselves from any threat. When the threat is gone, they come back. Who knew they were so smart?! Anyway, I did want to say I take 2 Atrantil, 2 NOW super enzymes, and 2 charcoal caps before meals that will bloat me. It does help. Detoxing as you go along is super important with Lyme or SIBO. It makes sense that as the bad bacteria dies you need to get it out or it will cause poblems. There is a good list of detox ideas on the site.

    Well I’m very interested to try this as I’ve been getting worse C last few weeks, especially over Christmas! I had a lot of the bad foods like sausage rolls, roast potatoes and wine lol. But I made a point of avoiding chocolate and dairy which make things a lot worse.

    Just curious, for those people who Atrantil hasn’t worked for, have you tried addressing all the other factors aswell? There are so many causes of constipation like lack of nitric oxide (from arginine/nitrates), tryptophan/serotonin, too much homocysteine (too much meat/lack of B6/B12/folate) , as well as the usual lack of water/fibre/exercise. I’ve made a list of about 20 things that can worsen constipation, and you have to address as many as possible to have any improvement.

    Would be interested to hear from above people about arginine/nitrates in their diet (beetroot, strawberries, leeks, nuts etc.), thanks. I do have peppermint tea, but could I try horse chestnut supplement separately or is it best to take the correct ratios? Many thx and good luck to all.

    I’ve had bloating and explosive diarrhea for years. I do have trigger foods and try to avoid them. I met with a gastro doctor a few years back but after spending a bunch of money on recommended supplements, nothing really changed so I went back to the usual routine of trying to avoid certain foods and trying not to be too stressed, which always upsets my stomach even more. I decided to try Atrantil after hearing the commercial on the radio and reading the positive reviews. For $40, I figured it was worth a try. I didn’t take the recommended dose of two tablets, three times a day. Rather, I took two tablets the first day (with food). The effect was felt almost immediately – no bloating and no diarheaa. I’m only on day two and have decided to limit it to one pill a day only. Right now, I’m feeling great, and quite honestly, my tummy feels calm for the first time in years. I understand this doesn’t work for everyone, but this, so far at least, has worked wonders for me, and it did it with a day.

    Hi, I’ve had methane-producing SIBO for two years now and nothing has given me long-term relief. Enteric-coated peppermint capsules were one of the first things I tried (which didn’t help at all), and they did give me bad acid reflux. Has anyone else had success with Atrantil who also had this issue with peppermint alone? I did see some comments that a few people had to stop Atrantil due to acid reflux issues with the peppermint. Any insight is appreciated. Thanks!

    I have had unexplainable abdominal pain and GI issues for over a year and a half (all blood word and scans came back normal). I’m supposed to be tested for SIBO in two weeks (have to wait because I was on probiotics). I just started the SCD diet and am so happy there are so many recipes and info available. I wanted to ask, if my test comes back positive, what alternative medicines/supplements are usually used and for how long? And how long does one usually stay on the SCD diet to ensure SIBO is eradicated? If it comes back positive I am planning on seeing a functional medicine doc as I do not want to use the antibiotics since they allegedly do not work as effectively and increase the chances of rebound. Any info is greatly appreciated!

I have several autoimmune diseases. i’m exhausted and can’t do anything before noon. I am weak and my body hurts. if like next time it happens i’m going to ER and see what they do. I do dislike ERs for the fact that you usually have 10 people talking to you and then you see a doctor and hour later if you’re lucky. i’m preparing for a surgery on my Achilles in November and I can’t have this hanging over my head anymore.

    Hi! I am currently on antratil as prescribed by my dietician for my tummy troubles. I was diagnosed with methane sibo/candida/ and adrenal fatigue. I have been on low fodmaps as well as a restrictive diet for 2 months. I have in all honesty not felt any better, my tummy did seem to calm down but after eating something off my list I was back to square one. Thankfully i recieved this and began taking 3 days ago. Since i have experienced raging sugar cravings, extreme fatigue, an odd facial rash with breakouts and swelling of my sinuses and left upper cheek and eye. I am sensitive to alott of medications so am unsure as to whether this is die off or an allergic reaction? The best way to describe myself overall is having an extreme flu.

    I am currently on Atranril and have been for about 6 weeks. The diarrhea is better but nothing else has changed. I am on a beta blocker for blood pressure and have tried to increase the Atrantil for 2 a day to 3. I can’t take more than 2 a day because my BP goes to low. I’m hoping it will work in time for the bloating on only taking 2 a day.

    I’ve been dealing with UC since my 20’s (I’m 57 now). I’ve been able to manage it OK? I’ve had mild to bad episodes off and on. One of my worst was while pregnant with my 2nd son, treated with hydro-cortisone, I made it through and I had a healthy baby!! This past year my UC has returned in full force. I had a stool test and it showed strep, so my alternative doctor has been treating it with antibiotics, probiotics, Ultra-Clear supplement, etc. About week ago I decided to try Atrantil and I felt it was working, they told me not to use the probiotic while taking it….well yesterday everything went bad. I’m not sure if I got a stomach flu or a reaction or die off? I’m thinking its a stomach flu, because I had a temp, achey, major diarrhea and now bleeding. I do feel a little better today, but still diarrhea and bleeding. 🙁

    I tried Atrantil and it didn’t work. I have such bad constipation and bloating! I had high hopes for this product. It made me nausea and abdominal pain and worsened the constipation.
    On a side note I didn’t like how I felt overall. Its hard to describe but I was more tired than usual and it took most of the day to have the feeling wear off.
    Sorry wish I could have been more positive about the product.
    Hopefully I can request the refund with no hassle!

    Unfortunately atrantil didn’t work for me. Neither did a half dozen other SIBO protocols I was put on by functional medicine doctors (including Chris Kressor). I’m now seeing a doctor that studied under Dr. Mark Pimental and Dr. Allison Seibecker who is a guest speaker at this year’s SIBO symposium with still no improvement in symptoms. I was even eating the SIBO specific diet for months while taking powerful antimicrobials with no improvement. Starting to wonder if cavitations and dental health are to blame. Already had one cavitation surgery and wondering if it wasn’t done properly. My sister in law had cavitation surgery and her SIBO went away almost overnight. More research needs to be done in regards to dental health and gut health. The beginning of the GI system is indeed the mouth.

    This is such a well laid out explanation of possible cause of unrelenting bloat and you built up the suspense beautifully. Although your solution turns out to be something we have tried for my badly suffering 19year old daughter, I am willing to try it again. She is currently taking a product (another doctor-formulated one) called RESTORE. First of all, Can you please comment at all on RESTORE as I have been meaning to ask you guys if you have any experience with this and also is it safe to take Atrantil with RESTORE? Is it also safe to take Atrantil with probiotics when she restarts her probiotics (while you are on the Restore, it is recommended that you stop digestive enzymes and probiotics so she has only been taking Restore for two weeks now. No significant change btw). Your posts are very helpful. I wish you and Jordan would see/talk to patients but thank you for your good work Steve. Moms like me live to read your advice

      Hi Ann, were you able to contact the company to find out the answer? I’m also on probiotics and just started RESTORE and am curious if I need to stop everything while taking Atrantil. And good info on not mixing probiotics with RESTORE…I had no idea! Just read the indications from RESTORE’s website. Guess I was so desperate for a solution that I rushed to buy the bottle without fully reading all the research.
