No FillersIf you’re here, you’ve just read about the second meal effect: how the right kind of prebiotic fiber can feed your gut bacteria overnight, helping them produce compounds that influence how you respond to food the next morning.
So the next question is obvious:
What’s actually in this formula, and what should you expect if you take it consistently?
Let me walk you through both.
This is the foundation of the formula.
Sunfiber® is the ingredient that makes the whole overnight fermentation story possible.
It is a slow-fermenting prebiotic fiber, which means it reaches the large intestine and feeds beneficial gut bacteria gradually — not all at once. That slower fermentation matters, because it helps your bacteria produce short-chain fatty acids over time, including butyrate.
And butyrate is one of the key compounds behind the second meal effect.
In other words: this is not just a fiber for regularity. It is the kind of prebiotic fuel that helps your gut bacteria work through the night, producing the compounds that may influence how your body handles food the next morning.
It is also one of the best-studied fibers for digestive tolerance and comfort, which is why it supports the mechanism without the harshness many people expect from fiber supplements.
Clinically shown to increase Bifidobacteria, one of the key bacterial groups involved in fiber fermentation and short-chain fatty acid production. Sunfiber provides the fuel. PreticX grows the workforce that processes it. More of the right bacteria means more butyrate production overnight.
Sunfiber and PreticX are the primary fuel. These next three help create the conditions for your gut to do its job.
Selectively targets harmful bacteria without disturbing the beneficial ones. In clinical trials, participants taking PreforPro alongside probiotics showed increased Lactobacillus populations and greater short-chain fatty acid production. Clears the way so your prebiotic fuel works more effectively.
Coats and soothes the gut lining, reducing irritation from years of inflammation. Laboratory studies also suggest its polysaccharides may feed beneficial bacteria. Centuries of traditional use, and the soothing benefits are well established.
Enhances trace mineral absorption so nutrients reach the cells that use them. Early research suggests it may also support gut barrier integrity. A healthy gut lining is the foundation everything else builds on.
One of the most interesting things about this formula is that people often notice changes in a similar order.
Not everyone experiences it the same way, of course. But across more than one hundred reviews, a pattern keeps showing up:
First the bloating improves. Then digestion becomes more regular. Then, with consistency, some women start noticing broader changes — including changes on the scale.
Here’s how that pattern often unfolds.
This is usually the first thing people notice. The slippery elm and Sunfiber start working almost immediately to soothe the gut and support regularity. Many people report less bloating within days.
“After three days of taking Better Gut Prebiotic Fiber Plus, the stomach problems I had experienced for months subsided. Within two weeks, they had cleared up completely.”
“After trying many recipes, herbal and OTC remedies, I thought I’d never find a solution for my constipation problem. Thanks to Better Gut Prebiotic Fiber, I am finally getting control of my problem. My gut and elimination are working wonderfully. Easy to take and worked within a few days. I won’t be without it!”
As your gut bacteria adjust to the daily prebiotic fuel, digestion often starts to feel more consistent and comfortable.
This is when many women begin describing a flatter stomach, less heaviness, and a more noticeable sense that their digestion is finally working with them instead of against them.
“I have suffered with bloating, smelly gas, constipation, and IBS for over 20 years. Nothing has gotten rid of the bloating until now. It took about 2-3 weeks before all of my symptoms began to decrease. The biggest difference was my flat stomach in the morning and throughout the day.”
This is where the deeper benefits of daily prebiotic support can start to show up.
With consistent use, your gut bacteria have more opportunity to produce beneficial short-chain fatty acids, and the research suggests that may support healthier glucose handling over time.
This is also the stage where we start hearing from some women about changes on the scale — often alongside less bloating, better regularity, and a greater sense of ease around digestion overall.
“Bloating is way down and I’m losing weight without even trying. Joint pain is lessened and energy is increased. I can’t believe how much difference it has made.”
“I’ve lost 12 Pounds already and feel healthier than I have in a long time.”
Individual results may vary. These are personal experiences shared by members of our community.
You can stir it into your morning coffee, oats, smoothie, or a simple glass of water. It is virtually tasteless, takes about 10 seconds, and fits easily into a routine you are already doing.
That’s it.
No complicated protocol.
No timing windows.
No pills to remember.
Just one daily scoop to feed the bacteria you want more of.

This is the pattern that keeps coming through in the messages we receive.
Women who had been cutting calories, exercising more, and doing everything they had been told — yet still feeling stuck.
Not because they were lazy.
Not because they lacked discipline.
But because their gut may not have been getting the kind of support it needed.
That is exactly what this formula was built to change.
Better Gut Prebiotic Fiber Plus is designed to give you more than a jar of powder.
When you start your protocol, you also get education, digestive support, and access to expert guidance — so you understand what is happening, know what to expect, and have support along the way.
Full access to The Gut Solution, our acclaimed docu-series featuring 40+ world-leading gut health experts. Over 2.2 million people have engaged with our educational events, and this is the one that started it all.
You will hear from gastroenterologists, microbiome researchers, naturopaths, and functional medicine doctors on topics like bloating, leaky gut, the gut-brain connection, and how the microbiome influences whole-body health.
If you want to go deeper into the science behind what is happening in your gut, this is where to start.
You will also get a free bottle of our bestselling digestive enzyme formula with your first order.
While Better Gut works more gradually by feeding beneficial bacteria and supporting long-term gut health, Digest & Debloat Pro helps support digestion at the meal level right away.
Together, they support both sides of the digestive equation: what happens during the meal, and what happens after it.
You will also get access to our private community, where you can ask our naturopath team your gut health questions directly.
Wondering if what you are noticing in week two is normal? Want guidance as your digestion starts changing? Ask inside the group and get a personalised response from a qualified naturopath.
It is practical support, right when you need it.
The formula, the education, and the support – all backed by a 30-day guarantee.
Research on prebiotic fiber suggests the benefits build over time as the microbiome adapts.
A single bottle is a great place to start. But 90 days gives your gut bacteria a much better runway to adjust to the daily fuel, which is why the 3-bottle option is the protocol we recommend most often.
It also gives you the best value, the deepest discount, and all of the bonuses.
I want you to try this without worrying. Give it 30 days. If the bloating hasn’t improved, if your mornings don’t feel different, just email us and we’ll refund you. No forms, no fuss.
I’d rather you try it and see for yourself than wonder whether it could have worked for you.
But I have a feeling you’ll notice something within the first couple of weeks.
I’ve watched so many women go through this same pattern. Curious at first. Then the bloating drops. Bathroom trips become regular. Then the scale starts moving. And then the emails come in... more energy, clearer skin, better mood. Your gut affects everything from head to toe, and I never get tired of hearing how it plays out.
Give it 90 days of the right fuel. I think you might be surprised how much changes.
When you choose the 90-day subscription, three bottles of Better Gut Prebiotic Fiber Plus are shipped to you automatically every 3 months. You can cancel, skip, or pause anytime with no penalties and no hoops. Just send us an email or manage it through your account. We’ll always notify you before your next shipment, so you have plenty of time to adjust.
Absolutely. The Starter option gives you a single bottle delivered monthly at 15% off. It’s a great way to try it. You can cancel anytime. The bonuses (The Gut Solution Docuseries and free Digest & Debloat Pro) are only included with the 3-bottle protocol, but you still get naturopath access and Inner Circle membership with any subscription.
One scoop per day, mixed into any drink. It dissolves completely, has no taste, and won’t thicken your beverage. Most people add it to their morning water, coffee, or smoothie. Take it at the same time each day for best results.
This is one of the most common questions we get, and the answer is almost always no. The reason most fiber supplements cause bloating is because they ferment too quickly in the upper gut. Sunfiber® is specifically designed to resist early fermentation and travel to the colon intact, where it ferments slowly over 12–24 hours. In clinical studies, Sunfiber® actually reduced bloating compared to other fiber types. Most of our customers report less bloating within the first week, not more.
Most people notice reduced bloating and improved digestion within the first 1–2 weeks. Regularity typically follows in weeks 2–4. The deeper changes – energy, mood, and what many of our customers report on the scale – usually become noticeable between weeks 4 and 8. That’s why we recommend giving it the full 90 days.
We always recommend consulting with your healthcare provider before starting any new supplement, especially if you’re currently taking medications.
Yes. Sunfiber® dissolves completely and has virtually no taste or texture. You can mix it into water, coffee, juice, or a smoothie without noticing it. Several of our customers have told us they forget it’s even in their drink.
Of course. Here it is:
Free shipping on all subscription orders. If you’re not happy, email us within 30 days and we’ll refund you. No forms, no fuss.
