Sharing is caring!

Before we dive into my top 10 products for SIBO and IBS, I need you to know something important.

For almost 20 years, I’ve been compiling every single product I’ve tested, tried, and researched for gut healing.

Every supplement, food brand, kitchen tool, practitioner. Everything.

This massive database lives in what I call the Ultimate Gut Health Product Guide (it’s actually a giant spreadsheet, but that sounds way less exciting).

And it’s completely free.

Inside, you’ll find:

• 18+ tabs organized by category
• Hundreds of products I’ve personally tested
• My notes on what works and what doesn’t
• Exclusive discount codes on everything
• Community practitioner referrals
• And so much more

I mention this upfront because while the 10 products I’m sharing today are my absolute essentials for SIBO and IBS, they’re just the tip of the iceberg.

The full guide is your roadmap to everything I’ve learned over two decades of healing.

Now, let’s talk about these 10 products.

My Top 10 Gut Health Products After Healing SIBO and IBS

Click HERE to save this article for later.

I didn’t just wake up one day and decide these were “the best.”

These products earned their place through:

1. Personal use during my own SIBO treatment and IBS management
2. Measurable results (confirmed through testing)
3. Evidence-based research backing their mechanisms
4. Continued use even after healing

[And yes, I have discount codes for you on most of them because I genuinely want you to have access to quality products without breaking the bank.]

Let’s dive in.

1] Just Thrive Health Probiotic

What it is: A spore-based probiotic that survives stomach acid and actually makes it to your gut.

Why it’s #1 for SIBO and IBS:

After testing over 10 different probiotics during my gut healing journey, Just Thrive was the game-changer.

Here’s what makes it different: Most probiotics die in stomach acid before they ever reach your intestines. Just Thrive’s spores have a protective shell that allows them to survive the journey and actually colonize where you need them.

The SIBO Connection:

SIBO creates a bacterial imbalance in your small intestine.

After treatment (antibiotics or herbals), you need the RIGHT probiotics to repopulate with beneficial bacteria. Spore-based probiotics are crucial here because they:

• Don’t feed bacterial overgrowth
• Support immune function (70% of which lives in your gut)
• Help reestablish healthy bacterial balance
• Produce antioxidants directly in your gut

The IBS Connection:

Research shows spore-based probiotics can significantly reduce IBS symptoms including bloating, gas, diarrhea, and constipation. They work by strengthening your gut lining and reducing inflammation.

How I use it:

I take 1 capsule daily [alternatively, I’ll also sometimes take their probiotic gummy form]. Way back when, I started with one every other day for the first week to assess tolerance.

Who it’s for:

• Anyone recovering from SIBO (especially after treatment)
• People with IBS (all types)
• Those who have tried probiotics with no results
• Anyone dealing with chronic bloating

Who it’s NOT for:

• People with active, untreated SIBO (and this is not because you CAN’T, but rather that it didn’t work for me)
• Those with histamine intolerance (start very slowly)

The science:

Bacillus spores have been shown in clinical studies to survive the GI transit 100% and support digestive and immune health. They increase microbial diversity, which is critical for long-term gut health.

2] Dysbiocide

What it is: A proprietary herbal blend designed to address bacterial overgrowth in the small intestine.

Why it made my top 10:

When I was treating SIBO, my functional medicine doctor put me on the “natural antibiotic” protocol instead of Rifaximin. Dysbiocide (paired with FC-Cidal, which we’ll get to) was the cornerstone.

The research:

A study published in Global Advances in Health and Medicine showed that herbal therapy using Dysbiocide and FC-Cidal was as effective as Rifaximin for treating SIBO, with 46% of patients showing negative breath test results after treatment (compared to 34% with Rifaximin). [source]

What’s inside:

Dysbiocide contains a synergistic blend including:

• Artemisia (wormwood)
• Berberine-containing herbs
• Other antimicrobial botanicals

These work together to target unwanted bacteria while supporting gut lining health.

How I used it:

I took 2 capsules twice daily with meals for 30 days during my SIBO treatment protocol. I paired it with FC-Cidal (see #10) for comprehensive coverage.

Important note: This is NOT a forever maintenance product. This is for active SIBO treatment. Always work with a practitioner when treating SIBO.

Who it’s for:

• Anyone treating SIBO with herbal antimicrobials
• People who can’t tolerate or don’t want antibiotics
• Those who haven’t responded to Rifaximin

Who it’s NOT for:

• Pregnant or nursing women
• People not actively treating diagnosed SIBO
• Those with certain medication contraindications

Get it: Available through professional supplement dispensaries | I have it in my Fullscript dispensary at 20-25% off

3] Just Thrive Health Digestive Bitters

What it is: A blend of 12 clinically-proven bitter herbs in capsule form (no bitter taste).

Why it made my top 10:

Digestive bitters are centuries-old medicine that modern diets have completely eliminated. They activate your body’s natural digestive processes by stimulating bitter taste receptors throughout your entire digestive tract.

The SIBO/IBS Connection:

Both SIBO and IBS involve impaired digestive function. Your body stops producing adequate:

• Stomach acid
• Digestive enzymes
• Bile

Bitters trigger your body to produce ALL of these naturally. This is huge because proper digestion prevents undigested food from feeding bacterial overgrowth.

What makes Just Thrive’s formula special:

12 herbs including bitter melon, dandelion root, artichoke, ginger, and more work synergistically to:

• Stimulate gastric acid production
• Increase bile flow
• Activate pancreatic enzymes
• Support GLP-1 production (appetite regulation)
• Improve gastric emptying

How I use it:

I take 2 capsules 10-15 minutes before my largest meal of the day. On days when I’m eating out or having a heavier meal, I’ll take them with the meal.

Cue the taste:

Unlike liquid bitters that taste terrible, these digestive bitters come in capsules that deliver the herbs to your stomach and small intestine where you actually need them, without the nasty taste.

Who it’s for:

• Anyone with sluggish digestion
• People who feel food sits like a brick after eating
• Those with low stomach acid
• Anyone dealing with bloating and gas

4] Break Down

What it is: A comprehensive digestive enzyme formula that includes HCl (hydrochloric acid).

Why I created it:

After years of taking multiple digestive enzymes and HCl separately, I realized I needed ONE product that did it all without the horse-pill size. That’s why I formulated Break Down.

The SIBO/IBS solution:

Inadequate enzyme production means undigested food particles travel through your digestive tract. In SIBO, this feeds bacterial overgrowth. In IBS, it causes:

• Bloating
• Gas
• Abdominal discomfort
• Irregular bowel movements

Break Down addresses this by including:

• Broad-spectrum digestive enzymes (protease, lipase, amylase)
• HCL to support stomach acid
• Plant-based enzymes for gentle but effective digestion

How to use it:

Take 1 capsule with each meal. If you’re eating a particularly large or heavy meal, you can take 2.

Who it’s for:

• Anyone with bloating after meals
• People who see undigested food in their stool
• Those with low stomach acid
• Anyone recovering from SIBO who needs digestive support

5] Increase Now (HCl with Pepsin)

What it is: Hydrochloric acid with pepsin to support stomach acid production.

Why it made my top 10:

Low stomach acid is epidemic. And it’s a major contributor to both SIBO and IBS.

When you don’t have adequate stomach acid:

• Proteins don’t break down properly
• Bacteria that should be killed in the stomach survive and travel to the small intestine (hello, SIBO)
• Food ferments in your gut causing gas and bloating
• You can’t absorb nutrients properly

The difference with Increase Now:

Unlike standalone HCl supplements that can be harsh, Increase Now is formulated specifically for those with sensitive digestive systems. It provides the HCl you need without the burning sensation some people experience with other brands.

How I use it:

I take 1-2 capsules with meals that contain protein. I started with 1 and increased as needed. If you feel any burning, reduce the dose.

The test:

Not sure if you need HCl? Try the baking soda test (Google it) or notice if you get bloated after protein-heavy meals. Alternatively, you can do the Betaine HCl test [that’s the one I personally did] — and you can learn how to do it HERE. That’s a telltale sign of low stomach acid.

Who it’s for:

• Anyone with low stomach acid
• People who get bloated after eating protein
• Those over 40 (stomach acid decreases with age)
• Anyone who has been on PPIs (proton pump inhibitors)

Who it’s NOT for:

• People with active ulcers or gastritis
• Those taking NSAIDs regularly

6] Tummy Soothe

What it is: A comprehensive blend of immunoglobulins (IgG) and N-acetyl-D-glucosamine to support gut lining health.

Why I created it:

Leaky gut is often the underlying issue in both SIBO and IBS. Your intestinal barrier becomes compromised, allowing particles to cross into your bloodstream that shouldn’t be there.

Tummy Soothe addresses this with:

• Immunoglobulins (ImmunoLin): Bind to and neutralize harmful substances in the gut
• N-acetyl-glucosamine: Supports the mucosal lining

The SIBO/IBS Connection:

Both conditions damage your gut lining. Tummy Soothe helps:

• Repair the intestinal barrier
• Reduce inflammation
• Support immune function in the gut
• Create a protective barrier against irritants

How to use it:

Mix 1 scoop (4 grams) in water or other liquid once daily. I typically take it in the morning on an empty stomach, but you can take it any time.

Who it’s for:

• Anyone dealing with food sensitivities
• People with leaky gut
• Those recovering from SIBO
• Anyone with inflammatory gut conditions

7] Move Now

What it is: Magnesium bisglycinate, the most absorbable and gentle form of magnesium.

Why it made my top 10:

Constipation was my primary IBS symptom for years. Magnesium was the only thing that worked consistently without harsh side effects or dependency.

But not all magnesium is created equal. Most forms either:

• Don’t absorb well (magnesium oxide)
• Cause diarrhea (magnesium citrate at high doses)
• Don’t provide the calming benefits

The Move Now difference:

Magnesium bisglycinate is chelated to glycine, making it:

• Highly absorbable
• Gentle on the stomach
• Calming for the nervous system
• Supportive of healthy bowel movements

The SIBO/IBS Connection:

Magnesium plays a crucial role in:

• Muscle relaxation (including intestinal muscles)
• Nervous system regulation (stress worsens IBS)
• Migrating motor complex function (the cleansing waves that prevent SIBO)
• Sleep quality (poor sleep worsens gut symptoms)

How I use it:

I take 2 capsules before bed. This supports both relaxation and morning bowel movements.

Who it’s for:

• Anyone with constipation-predominant IBS
• People with poor sleep
• Those with high stress levels
• Anyone who needs gentle motility support

Who it’s NOT for:

• People with diarrhea-predominant IBS (may worsen symptoms)
• Those with kidney issues (consult doctor first)

8] Glutagenics

What it is: A powdered formula featuring L-glutamine, DGL (deglycyrrhizinated licorice), and aloe vera for gut lining support.

Why it made my top 10:

Despite the need for an impregnable defense, the intestinal epithelium is only one cell thick to accommodate the exchange of nutrients and water. [source]

When you have SIBO or IBS, that lining becomes damaged and inflamed. Glutagenics provides the building blocks to repair it.

The ingredients:

L-Glutamine (3.5g per serving): The primary fuel source for enterocytes (intestinal cells). Research shows glutamine can help:

• Reduce intestinal permeability (leaky gut)
• Support gut barrier function
• Decrease inflammation in the GI tract

DGL (Deglycyrrhizinated Licorice): Supports the mucosal lining without the blood pressure concerns of regular licorice.

Aloe Vera (inner leaf gel): Soothing and supportive for the intestinal lining.

How I use it:

I mix 1 scoop in water once daily, typically in the morning. The taste is pleasant (natural flavors) and it dissolves easily.

Clinical evidence:

Multiple studies have shown L-glutamine’s effectiveness in supporting intestinal health, particularly in conditions involving gut barrier dysfunction.

Who it’s for:

• Anyone with leaky gut
• People recovering from SIBO
• Those with food sensitivities due to intestinal permeability
• Anyone needing gut lining repair

9] Ox Bile

What it is: Bile salts derived from bovine sources that support fat digestion.

Why it made my top 10:

If you’ve had your gallbladder removed OR if you have SIBO, you likely have bile acid issues.

The SIBO Connection:

Bile acids serve two crucial functions:

1. They break down dietary fats
2. They have antimicrobial properties that keep bacteria in check

When bile flow is sluggish or insufficient, you get:

• Fat malabsorption (greasy stools, nutrient deficiencies)
• Bacterial overgrowth
• Bloating after fatty meals

The IBS Connection:

Many people with IBS have bile acid malabsorption, which contributes to diarrhea and fat intolerance.

How I use it:

I take 1 capsule (125mg) with meals that contain fat. If it’s a particularly high-fat meal, I’ll take 2.

Important note:

Ox bile can also be taken on an empty stomach before bed to support small intestinal bacterial balance. Work with a practitioner to determine the best approach for you.

Who it’s for:

• Anyone without a gallbladder
• People who get nauseous or bloated after eating fat
• Those with SIBO (bile has antimicrobial properties)
• Anyone with fat-soluble vitamin deficiencies (A, D, E, K)

Get it: Available through my Fullscript dispensary at 20-25% off | Brands I recommend: Allergy Resource Group, Biotics

10] FC-Cidal

What it is: A companion herbal formula to Dysbiocide, designed to support healthy microbial balance in the small intestine.

Why it completes the top 10:

FC-Cidal and Dysbiocide together form the research-backed herbal protocol for SIBO. While Dysbiocide (#2) targets certain types of bacteria, FC-Cidal addresses others.

The synergistic approach:

FC-Cidal contains herbs like:

• Olive leaf extract
• Berberine
• Other antimicrobial botanicals

Used together, these two products provide comprehensive coverage against the various bacteria that can overgrow in SIBO.

The study:

The same research that validated Dysbiocide showed that when used together, Dysbiocide + FC-Cidal were 46% effective at resolving SIBO (compared to 34% for Rifaximin). In patients who didn’t respond to Rifaximin, 57% responded to the herbal therapy. [source]

How I used it:

1 capsule twice daily with meals for 30 days, alongside Dysbiocide. Always as part of a comprehensive SIBO protocol under practitioner guidance.

Who it’s for:

• Anyone treating SIBO with herbal antimicrobials
• People using Dysbiocide (they work best together)
• Those who need a natural antimicrobial approach

Get it: Available through professional supplement dispensaries | I have it in my Fullscript dispensary at 20-25% off – Brand: Biotics Research

BONUS: 3 More Products That Changed My Gut Health Journey

Okay, I know I said 10, but I can’t NOT mention these three.

They’re not daily supplements, but they’ve been absolutely crucial to my healing and maintenance.

---

Bonus #1: BiOptimizers Magnesium Breakthrough

What it is: A full-spectrum magnesium formula containing 7 different forms of magnesium plus vitamin B6.

Why it’s a bonus pick:

While Move Now (#7) is my go-to for targeted motility support, Magnesium Breakthrough is what I use when I need comprehensive magnesium coverage across all body systems.

Here’s the difference: Move Now contains a single form (bisglycinate) optimized for constipation and sleep. Magnesium Breakthrough contains 7 forms that work synergistically:

• Magnesium Chelate – muscle recovery and building
• Magnesium Bisglycinate – gentle on the stomach, supports relaxation
• Magnesium Citrate – digestive support
• Magnesium Malate – energy production and chronic pain
• Magnesium Taurate – heart health
• Magnesium Orotate – metabolic function and athletic recovery
• Magnesium Sucrosomial – highly bioavailable without laxative effect

The SIBO/IBS connection:

Magnesium deficiency is incredibly common in people with gut issues because:

• Chronic stress depletes magnesium (and stress worsens IBS)
• Digestive dysfunction impairs mineral absorption
• Many gut-healing diets are naturally low in magnesium

How I use it:

I DRINK this one because it’s delicious, taking a scoop when I need comprehensive support beyond just motility. This is especially helpful during high-stress periods, after intense exercise, or when I’m dealing with muscle tension that’s affecting my digestion.

When to choose Magnesium Breakthrough over Move Now:

• You need stress support in addition to digestive support
• You’re dealing with muscle cramps or tension
• You want comprehensive magnesium coverage for overall health
• You have multiple magnesium deficiency symptoms (sleep issues, anxiety, muscle problems, digestive issues)

Bonus #2: Perfect Supplements Hydrolyzed Collagen

What it is: Grass-fed, hydrolyzed bovine collagen for gut lining support.

Why it’s essential:

Collagen is one of the primary building blocks of your gut lining. The hydrolyzed form is already broken down into smaller peptides, making it easier for your compromised gut to absorb.

How I use it:

1-2 scoops daily in:

• Coffee or tea
• Smoothies
• The Soothing Golden Latte from my 5-Day Bloat Fix

The gut-healing mechanism:

Collagen contains glycine, proline, and hydroxyproline amino acids that directly support gut barrier integrity. Research shows collagen peptides can help strengthen the intestinal lining.

Bonus #3: FoodMarble AIRE 2 Device

What it is: A handheld breath testing device that measures hydrogen in real-time to track food reactions.

Why it’s game-changing:

This device allows you to test how YOUR body responds to different foods without waiting for a doctor’s appointment or expensive lab testing.

How it works:

You eat a food, then breathe into the device at timed intervals. It measures hydrogen gas (a byproduct of bacterial fermentation) + methane (!) and shows you on the app:

• How your body responded to that specific food
• Your fermentation score
• Patterns over time

The SIBO/IBS application:

• Track which FODMAPs trigger your symptoms
• Monitor your gut health progress
• Identify food intolerances
• Guide your reintroduction phase after elimination diets
• Verify if SIBO treatment worked

How I use it:

I use it when reintroducing foods, trying new products, or if I suspect something is triggering symptoms. It takes the guesswork out of food reactions.
