Bloating… constipation…gas – those are the tell-tale symptoms of methane dominant SIBO (Small Intestine Bacterial Overgrowth), otherwise known as Intestinal Methanogen Overgrowth (IMO).
Methane SIBO is one of the trickier forms of SIBO to treat, and those with methane SIBO often require multiple treatment rounds to resolve.
That’s why today, I want to share some of the tested-and proven supplements that work best for methane dominant SIBO.
What Is Methane SIBO?
SIBO is a condition caused by overgrown bacteria in the small intestine. The bacteria consume the carbohydrate foods we eat, and ferment them into gas. Different types of bacteria produce different types of gas – and it is the gas that causes the symptoms of SIBO.
Methane SIBO is a little bit different in two key ways, however:
#1 Methane is produced by archaea, not bacteria
Technically, the microscopic organisms that produce methane gas are archaea, not bacteria. But like bacteria, archaea are a normal part of the gut microbiome.
#2 Archaea can overgrow in the large and small intestine
Thanks to the pioneering work of Dr. Mark Pimentel, MD and his team at Cedars Sinai Hospital in Los Angeles, we now know that the symptoms of methane SIBO can be caused by overgrowth in the small or large intestine
These 2 key differences are why methane SIBO has another name: Intestinal Methanogen Overgrowth. More on that here.
The names Methane SIBO and IMO are often used interchangeably. Here at SIBO SOS®, we use both names. In this post, we’ll call it methane SIBO.
How Do I Know If I Have Methane SIBO?
The most common way to diagnose methane SIBO is with a SIBO breath test.
According to Dr. Allison Siebecker, ND, generally a 3-hour conventional breath test with:
- Methane level below three is negative
- Methane level between 3 and 9, with constipation, is considered positive
- Methane level above 9 is considered positive (with or without constipation)
Some labs use slightly different numbers for interpretation.
How Can We Treat Methane SIBO?
Dr. Siebecker recommends one of these treatments for methane SIBO:
- Rifaximin plus neomycin (requires a doctor’s prescription)
- Rifaximin plus metronidazole (requires a doctor’s prescription)
- Allicin (the active component of garlic, found in the supplement Allimed) plus one other herb: berberine, oregano, or neem
- Elemental Diet
- Atrantil (alongside another treatment or alone for symptomatic relief)
Treating Methane Symptoms
In addition to treating the overgrowth of archaea directly with one of the above treatments, those with methane often have specific symptoms that they need relief from:
For bloating and gas, Gas-X, activated charcoal, and (my favorite) Atrantil are all recommended by Dr. Siebecker.
For constipation, Dr. Siebecker recommends adding more fat to the diet, magnesium oxide, and a probiotic without added prebiotics, like MegaSporeBiotic.

Hang In There!
Methane SIBO can be really difficult to treat, and I know sometimes it can feel like nothing will ever work.
If you’ve tried one treatment for methane SIBO without success, don’t be afraid to try another: not every treatment works for every person.
And remember that often it takes more than one round of treatment for success, too!
