Have you heard of the Nemechek Protocol?

It was developed by an autonomic dysfunction physician, Dr. Patrick Nemechek out of Arizona.

If you suffer from unexplained bloating that you can’t seem to get rid of, it may be a hidden case of SIBO. I went from chronically bloated (like 7-months pregnant bloated…) to flat tummy in less than 2 months by simply following Dr. Nemechek’s advice. Keep reading to learn more!

Parents around the world have been using this protocol with great success for their autistic children.

But there’s also hope for those of us battling SIBO, as this protocol focuses on restoring bacterial balance.

The best part of it all? It’s really just 3 foods or food-based supplements.

I know, I know…

I usually belong to the camp that believes “If it sounds too good to be true, it probably is.” But when I read Dr. Nemechek’s research and ideas behind the protocol for SIBO, it made total sense.

If you can give me just a few more minutes of your time, I’d love to share this information with you, and you can do with it what you will.

But I will say this, it just might change your life like it is changing mine.

For this post, I’m just going to focus on the SIBO side of things. I’ll probably do another post dedicated to the autism side in the future.


Do you have SIBO? It is an acronym for Small Intestine Bacterial Overgrowth. It happens when you have bacteria from the colon migrate into the small intestine. It results in digestive distress symptoms like bloating, gas, constipation, diarrhea and more. After suffering with SIBO for over a year, I've finally found a SIBO cure, and it's SO simple. Click to see for yourself!

What Is the Nemechek Protocol?

The protocol identifies SIBO and brain inflammation as the likely culprits behind developmental delays, ADHD, Autism and more.

If you haven’t already heard or read the research, the gut is often called our “second brain.” There is an undeniable link between gut health and brain health, which is why such incredible results can be had when you focus on restoring and balancing these two areas.

The Nemechek Protocol consists of 3 things:

  • Inulin (or Rifaximin for adults)
  • Pure Extra Virgin Olive Oil
  • Fish Oil

And it involves eliminating:

  • Omega-6 Oils
  • Probiotics
  • Digestive Enzymes

To be honest, I kinda freaked out a little about the no probiotics thing. I’ve ALWAYS been told to take probiotics for good gut health. And for the majority of people, that’s perfectly fine! But in severely immunocompromised individuals with major gut bacteria issues going on, Dr. Nemechek cautions against them.

We’ll discuss that more in a bit.

For all the details about the protocol, check out Dr. Nemechek’s book, The Nemechek Protocol for Autism and Developmental Disorders: A How-To Guide for Restoring Neurological Function.

Don’t let the title fool you, this protocol is for so much more than autism.

The Governing Principles Behind Dr. Nemechek’s Protocol

As I mentioned earlier, this protocol is two-fold. It deals with reducing brain inflammation and reversing SIBO.

1 – Science Behind Fatty Oils and Reducing Inflammation

The members of the fatty acid family are all necessary and beneficial in their own way, but they must remain in the proper balance to really support health.

When this balance is thrown out of whack, inflammation results. Countless doctors now believe that inflammation is the root causes of many diseases, so this is a key part of the protocol – and also the reason why it’s useful for so many chronic conditions.

Our ancestors ate a much more balanced diet than we do. Their Omega-6 to Omega-3 ratio was estimated to be about 1:1, which is ideal. Today, however, our ratios are more like 15:1, which is indicative of a highly inflammatory state. When Omega-6 levels go unchecked, they induce inflammation and encourage disease proliferation.

It should come as no surprise that Americans as a whole have such high levels of Omega-6s. Pick up just about any box of food from the grocery store, and you’ll see a list of inflammatory Omega-6 oils in the ingredients list.

So ultimately, the Nemechek protocol seeks to increase Omega-3s & 9s and drastically reduce Omega-6s. It achieves this through supplementing with high-quality extra virgin olive oil and high-potency fish oil.

2 – Science Behind Reversing SIBO with Inulin

I’m not going to dig too deep into what SIBO is because if you’re reading this, you probably already know.

But super complicated story short:

Small Intestine Bacterial Overgrowth (SIBO) occurs when the type of bacteria that’s supposed to live only in your colon get stirred up and migrate into your small intestine.

This bacterial overgrowth damages the intestinal wall, releasing a substance called lipopolysaccharide (LPS) into our tissue. When our white blood cells notice the LPS, they react by releasing highly inflammatory cytokines into the blood.

This is what is commonly known as leaky gut.

On top of that, some studies indicate that the actual bacteria can interfere with the autonomic system. Certain bacteria can send signals to the brain that alter our autonomic system and slow digestion.

Dr. Nemechek puts it this way:

The bacteria have learned the first rule in real estate: Location is everything.

The colon was no longer “enough” for the bacteria, so they decided to move to a better neighborhood where they could get a steady supply of nutrients to feed on and replicate.

Once bacteria feeds on these nutrients, they release waste products in the form of toxins and gas that cause our frustrating digestive issues.

Changing your diet to a cleaner one is very helpful and can give you great gains, but those gains eventually plateau because diet alone doesn’t solve the root issue, which is a bacterial imbalance.

Left unchecked, bacteria will simply continue to filter into the small intestine.

Dr. Nemechek suggests that you have to reestablish neurological control of the intestines in order to see lasting results. That’s why the Nemechek protocol addresses the gut AND the brain.

While the oils work to balance the Omega-3:6 ratio, the inulin works to push small intestinal bacteria back into the colon where it belongs, while also feeding the good bacteria. Basically, the good bacteria that’s supposed to be in the small intestine feed off the inulin. This results in an acid being produced that the trespassing bacteria don’t like, which makes them revert back into the colon where they belong.

Studies also indicate that inulin can have powerful immunomodulating effects.

Nemechek’s Recommended Supplements and Their Dosages

I agree wholeheartedly with Dr. Nemechek’s opinion that the vast majority of supplements are a waste of money. With little to no regulation, the supplement industry can be extremely dishonest and scammy.

Sometimes what’s listed on the label isn’t even in the bottle.

For this reason, I highly suggest sticking with the list of approved brands if you decide to try the Nemechek Protocol. Besides the foods/supplements below, Dr. Nemechek recommends the antibiotic Rifaximin for adults in lieu of the inulin. He says that in most adult cases, inulin is simply not enough.

However, I know many adults (myself included) are seeing results with just inulin. You’ll need to do your own research to make the best decision for your unique circumstances.

Here’s a video that explains the difference in how inulin and Rifaximin work:

As for the rest of the protocol, here are the tried-and-true brands that you can trust:

1 – Now Inulin Powder

It’s organic and sourced from blue agave with no fillers or preservatives. I just mix it in about a cup of water and drink it, but you can also add it to applesauce, oatmeal, yogurt, whatever.

The maximum inulin dose for adults in 2 teaspoons, but you need to work up to that, and many people don’t need that much. When it comes to inulin, it’s sort of a “watch and see” approach because everyone’s gut conditions are unique.

It’s recommended to start at a small amount like 1/8 of a teaspoon. Stay there for a week or so, watching for any new, worsening or improved symptoms. If your symptoms stay the same or improve, then you can increase to ¼ tsp after 1-2 weeks. Continue increasing the dosage until you either “hit your sweet spot” as far as relief of symptoms go or you hit 2 tsps.

It’s not at all uncommon to only need max 1 tsp to achieve the desired results, which is the alleviation of SIBO symptoms and reversal of bacterial imbalance.

Note: Symptoms like gas and bloating do tend to worsen when first starting inulin, but it should only last a few days.

2 – Nordic Naturals Ultimate Omega

These are available in either liquid form or as capsules. I use the liquid form as it’s more concentrated, so it doesn’t take as much to get the job done.

And no, it doesn’t taste fishy and no gross fishy burps afterward. It actually has a slight lemon flavor that’s easy to gulp down in a spoon.

2019 UPDATE: The California Olive Ranch brand has formulated a new EVOO product they’re calling the “Destination Series.” This type is NOT COOC-certified. Before you buy, check for the COOC seal.

As with many supplements, olive oil is easy to adulterate, and many of the olive oil bottles you see on store shelves are not 100% pure olive oil. It’s critical to use only 100% pure extra virgin olive oil that’s certified by COOC.com.

California Olive Ranch is the brand Dr. Nemechek approves, and the one that I use, although there are others approved by COOC.

The dose is 1-2 Tablespoons per day and cooks with it. I’m only a couple of weeks in, but I take 1 Tbsp in the morning and sauté all my vegetables in it – and sometimes eggs, too.

Foods and Supplements to AVOID on the Nemechek Protocol

If you’ve had SIBO for long, you know that the list of foods to avoid is looong. In my case, Lyme disease was the culprit behind my SIBO and autoimmune disorders. Within a year of diagnosis, I was having allergic reactions to almost everything. At one point in time, my list of “safe foods” consisted of beef, carrots, green leaf lettuce, and cucumbers.

It was terrible, and part of the reason why I lost so much weight. Anyways, I digress…

The Nemechek Protocol only involves eliminating 3 things:

  1. Omega-6 oils

These include:

  • sunflower oil
  • safflower oil
  • soy oil
  • corn oil
  • cottonseed oil
  • grapeseed oil
  • peanut oil
  • vegetable oil
  • margarine
  • shortening

If you have to buy something processed, stick to products made with coconut oil or palm kernel oil (as long as you aren’t allergic, of course). You’ll notice the vast majority of packaged/processed foods contain some sort of Omega-6 oils.

  1. Probiotic supplements

Dr. Nemechek believes that probiotics have the potential to increase the numbers of all bacteria, as opposed to just the “good” guys. While on this protocol, he advises to stop probiotic supplements, but fermented foods such as sauerkraut and kefir are fine.

  1. Digestive Enzymes

With the gut in such a fragile state, Nemechek believes digestive enzymes could do more harm than good. I don’t necessarily agree with that, but again, this is one aspect you need to do your homework on and determine what will be best for you.

My Experience on the Nemechek Protocol

I just started the Nemechek protocol for SIBO about 2 weeks ago.  I’m journaling everything, and I’ll update this post as I go along.

So far, I can tell you that my bloating and gas flared up the first 2 days after taking inulin. I didn’t react at all to the oils.

Around Day 6, I started seeing a change in BMs. They were easier and more productive.

About a week into the protocol is when I noticed the most exciting change!

It requires a little back story:

I mentioned earlier about my extremely limited list of foods I could eat. Anything outside of that, the lymph nodes in my neck would swell tremendously. They actually swell whenever I eat ANYTHING, no matter what it is, but it’s usually manageable. Only for certain foods (like chicken of all things) would they swell to a point that was scary.

Well, around day 8 of the Nemechek protocol, I noticed that my lymph nodes weren’t swelling as bad after eating! Granted, it’s only a small difference, but there definitely IS a difference. I can’t tell you how much that means to me to have hope of eating normally again!

I’ve lost over 25 pounds since my SIBO and autoimmune conditions first flared up. I didn’t have any weight to spare as I’ve always been very petite, so this weight loss put me in a dangerous place.

I’m waiting to be on the protocol one month before I weigh myself again, but I think I’m finally starting to absorb nutrients again!

How Long Does It Take the Nemechek Protocol to Work?

The answer to this question will be different for everybody, but as Dr. Nemechek says, the process usually requires a little patience.

You didn’t get this sick overnight, and your healing won’t happen overnight either – unless, of course, the Lord intervenes.

He compares it to hair growth. We don’t usually notice our hair growing day by day, but it is. And after a month, you’ll see it’s a bit longer. Then after several months, it’s time for a haircut.

So if you decide to try the Nemechek protocol for SIBO or any of the other conditions it can help, plan to be on it for the long haul – at least several months. I personally will do it faithfully for 6 months before deciding one way or the other.

I hope this information helped you a bit today. Have a question? Ask it in the comments, and I’ll be sure to answer!

Updated Dr. Nemechek Protocol review

Updated July 31, 2018:

I’ve been on the Nemechek Protocol for about a month now. I’m not doing the Rifaximin as of now but that may change. So far, I’m still at the bottom dose of inulin at 1/8 tsp, 1 tsp of fish oil, and 1.5 tablespoons of extra virgin olive oil. I’ve attempted to increase the inulin dosage, but I get severe bloating when I do that.

Around week 3, I started getting nauseous after taking the supplements. I’m not really sure what’s causing that, but I’ve asked around in the Nemechek Protocol community, and it seems to be par for the course and something that I need to just push through.

I have noticed that eating something helps it go away almost immediately, so I take all the supplements when I first wake up, followed by a light breakfast, and nausea leaves.

As good news, constipation is a thing of the past! I can tell this protocol has been great for keeping things moving, which goes a long way to avoiding the toxin buildup that I struggled with before.

I also mentioned that I was waiting to weigh myself until I had been on the protocol for 1 month. I weighed myself today, and I haven’t lost a single pound the whole month! That’s great news for me as I’ve been losing weight dramatically each week, and I didn’t have any weight to spare to begin with.

That makes me think perhaps I’m starting to absorb nutrients again, which was one of my biggest reasons for starting the Nemechek Protocol for SIBO.

Nemechek Protocol Review: My Experience After 3 Months

Updated: October 1, 2018

Well, it’s been 3 months now, and there have been a lot of changes! At the beginning of September, I finally got a prescription for Rifaximin (Xifaxan). I had some pretty crazy “steroid rage” while on it, which is weird because it’s an antibiotic, but no other side effects other than that.

Around Day 5 of taking the antibiotics for SIBO, I noticed a significant decrease in bloating. Now, I’m about 3 weeks post-Rifaximin, and I have little to no bloating anymore.

I’ve also seen an improvement in my food sensitivities. I can now eat more foods (including chicken again!) with very minor reactions. Considering my lymph nodes blew up like a pufferfish to E-V-E-R-Y-T-H-I-N-G before, I consider that such a blessing!

At this point, I’m considering switching from Nordic Naturals fish oil to NOW DHA capsules because the latter has more EPA, which is really important for adults. As for the extra virgin olive oil, I’m still at 2 tablespoons, which is what Dr. Nemechek recommends.

Overall, I’ve seen enough steady, slow improvement that I will most certainly stick with the Nemechek Protocol long term!

8 Month Update: Continuing the Fight Against SIBO

Updated: March 4, 2019

Well, I meant to update at the 6-month mark, but life has been hectic. So here we are in March 2019, and I’ve been on the Nemechek Protocol for 8 months now.

It’s funny. I remember reading testimonials from others who were 6 months to a year into it and thinking:

“But that’s sooo long! I want to feel better now! It’ll take forever for a year to get here!” 

And yet, 8 months have flown by. Now I’m reaping the benefits so many others have experienced – benefits that I had previously only dreamed of.

So things were going great until the beginning of January. I’m still not sure what happened, but I started having terrible tummy troubles that started an hour or so after eating a store-bought salad. Within days, my SIBO symptoms were back full force!

It’s all a guessing game, but I suspect some sort of food poisoning with that salad (I’m looking at you, romaine!).

Dr. Nemechek believes food poisoning is where many SIBO cases begin.

Regardless, I decided to do move forward with another round of Rifaximin. So to recap, I started the second round of Rifaximin about 4 months after the first.

This time, I didn’t see the stark, immediate gains I did last time. By day 10 of the meds (last day), my SIBO symptoms had only improved a little.

Not gonna lie, I was very disappointed. I fully expected to see the night and day difference like the first round.

However, after a few days of sulking, I started noticing an improvement in BMs, bloating, and food sensitivities. Now nearly 2 months post-Rifaximin Round 2, I continue to improve. So this time, it seems improvement was ‘slow and steady’ vs immediate. Interesting!

But hey, improvement is an improvement, so I’ll take it.

I mentioned in the previous update that I was considering switching to the NOW fish oil, and I did. It didn’t make me nauseous at all, and I’m getting higher doses of EPA, so it’s a win!

I have to admit I’ve gotten a little lazy with remembering doses.

By the way, that happens when you start feeling better! Desperation drives us to stick to treatment routines exactly as intended. When you feel better and don’t have those constant symptom reminders, it’s easy to get slack. So beware, and keep that in mind! 

Right now, I’m enjoying feeling well. A few weeks ago, the Lord really helped me during a Sunday morning service, and I’m praising Him for what appears to be a “break” from all this.

I’ll update again when I’ve been on the protocol for 1 year! As always, post any questions in the comments, and I’ll respond as best I can!

Frequently Asked Questions

Are there any negative reviews of the Nemechek Protocol?

Yes, actually. In all aspects of health, everyone is different, and every physical body responds differently. So there are some people who don’t improve on this protocol. They are far outweighed by those who do, but still, you should know that it doesn’t have a 100% success rate.

In talking with others, it seems many of the negative reviews stem from people with severe histamine issues who cannot tolerate high doses of fish oil.

Is there a 'Nemechek Protocol for Adults' book?

Not yet, but I’ve heard one is in the making! For now, we have the autism book, his blog, and youtube videos to guide us through the process.
