Natural Relief for Diarrhea, Constipation, Pain & Cramping

Heather’s Tummy Fiber is a 100% Acacia Senegal powder — a pure, water‑soluble fiber harvested from the Acacia Senegal tree.

It is the highest grade available, whole‑food, and plant‑based. Acacia Senegal has been used for digestive health since the time of the Egyptian pharaohs.

Heather’s Tummy Fiber is classified as a medical food for the dietary management of IBS symptoms.

How Does Acacia Senegal Help IBS?

Acacia Senegal gently regulates bowel motility. It dissolves in water to form a soft gel in the colon, which:

• Absorbs excess fluid to stop diarrhea
• Softens hard stools to relieve constipation
• Normalizes muscle contractions to prevent pain, spasms, and cramps

What Are the Main Benefits?

• Natural motility regulation – works for both diarrhea and constipation
• Prebiotic effect – feeds healthy gut bacteria
• Reduces gas & bloating – slowly fermenting, low‑FODMAP fiber
• Pain relief – stabilizes contractions to prevent cramping
• Safe for daily use – no stimulants, no dependency risk

Why Is Acacia Senegal Better Than Other Fibers?

• 100% soluble fiber – no insoluble fiber to irritate the gut
• Slow fermentation – minimizes bloating and discomfort
• Excellent gastrointestinal tolerance – gentle on sensitive stomachs
• Gluten‑free & low‑FODMAP – safe for IBS diets

Is Heather’s Tummy Fiber a Drug or Laxative?

No. It is not a drug, not a laxative, and not an anti‑diarrheal.

It’s a natural, slowly fermenting soluble fiber that works the same way as fiber from food — just in a concentrated, pure form.

How Does It Maintain Long‑Term Stability?

Once your symptoms are under control, daily use helps:

• Keep bowel movements regular
• Prevent IBS flare‑ups
• Maintain smooth, comfortable digestion day‑to‑day

Is It Safe for Children and Long‑Term Use?

Yes. Heather’s Tummy Fiber is:

• Safe for all ages
• Non‑habit‑forming
• Free from GI irritants and stimulants
• Suitable for lifelong daily use

✅ 100% Acacia Senegal – highest quality

✅ Medical food for IBS – clinically backed benefits

✅ Daily digestive stability – gentle, effective, natural relief

It's a Slowly Fermenting Prebiotic

Clinical studies have also shown that Heather's Tummy Fiber Supplement, made from Acacia Senegal, has unique benefits over other soluble fiber sources.

In the large intestine, Acacia Senegal fiber stimulates the development of bifidobacteria and lactic acid bacteria, which leads to the production of short-chain fatty acids (SCFAs). These SCFAs play numerous beneficial roles in the physiology of the human body.

Additionally, daily consumption of Acacia Senegal fiber at doses below 15 grams/day has been shown to avoid the gas, bloating, and cramping often associated with other soluble fiber supplements.

As much or as little as you like! There is no minimum amount of water required to mix Heather's Tummy Fiber.

You can use just enough water to liquefy it, or you can use a whole glass. Both options are equally effective.

As long as there is sufficient water in your gut, the soluble fiber will work properly.

Heather's Tummy Fiber has no viscosity, so there is no choking risk at all. This means you are not required to drink a large glass of liquid with it—unless you prefer to.

You only need to use however much (or little) water it takes to dissolve the powder. Alternatively, you can simply sprinkle the fiber on moist foods instead of mixing it into a drink.

Because the fiber does not thicken in liquids, it cannot coat your throat, and therefore does not pose a choking hazard.

Add the fiber to an empty cup and then add just enough water to liquefy it - just like dissolving cornstarch - to prevent clumps.

Once liquefied, you can drink it right away or fill the rest of the cup with more liquid if you prefer. You can also cook with it or add it to soft, moist foods like applesauce or oatmeal.

How is Tummy Fiber Better than Other Fiber Supplements?

Heather's Tummy Fiber is very different from high-viscosity fibers like psyllium and methylcellulose. Those fibers require a large glass of water to prevent choking and must be consumed quickly before they thicken.

With Heather’s Tummy Fiber, there is no such concern. It stays smooth in liquids, offers flexible dosing, and poses no choking risk—making it safe, easy, and effective for daily IBS management.

Plus Tummy Fiber Acacia Senegal is a slowly fermenting prebiotic that is unrelated to the rapidly fermenting prebiotic FODMAP fiber supplements

Here's how to easily schedule your Tummy Fiber with meals, supplements and medications:

Treat your fiber like food. The easiest and most effective way to take Heather's Tummy Fiber is by adding it directly to your meals — ideally at breakfast and dinner. This gives your digestive system 24/7 IBS symptom coverage.

Once you combine fiber with your meals, the only remaining concern is supplements and medications that must be taken on an empty stomach. Simply schedule those around your meals and fiber intake.

Heather’s Tummy Fiber will not interfere with nutrients in food and will not interfere with medications or supplements that can be taken with food.

For medications or supplements that require an empty stomach, the rule of thumb is to take them one hour before meals or two hours after you eat food or your fiber.

Yes, you can! Heather’s Tummy Fiber is completely inert and stable, which means you can’t damage it, and it will not go bad. It is unaffected by heat, cold, or time.

You can safely add the fiber to any food or drink— whether you're cooking, baking, or mixing it into a bottle of water. Add it to your meals, beverages, or recipes as far in advance as you like.

The fiber will not mold, mildew, spoil, or lose its effectiveness. Whether it’s refrigerated, frozen, boiled, baked, or microwaved, the Tummy Fiber will stay fresh, effective, and it will work regardless..

The fiber is impervious. The food or drink you add it to will eventually go bad, but the fiber itself won’t. So prepare it ahead of time without worry.

This flexibility makes Heather’s Tummy Fiber ideal for meal prepping, cooking, or on-the-go use, supporting your IBS management routine with zero hassle.

No. Tummy Fiber is 100% Acacia Senegal, which is a 100% soluble fiber.

Soluble fiber cannot cause or worsen diarrhea or constipation, or flip one to the other.

But it also won't help you until there is enough of it in your gut 24/7 to regulate motility.

In the meantime, everything that is impacting your gut will keep impacting it.

It's a process to work up your dose, and you are still on a very low end.

Details:

There are two kinds of fiber, insoluble and soluble.

Insoluble is a stimulant and can set off IBS symptoms, and if you have strictures, it can cause intestinal blockages.

The Tummy Fiber is pure soluble fiber so it won’t do that – it can't.

It’s not a stimulant, it’s a bowel motility regulator.

It can’t cause blockages, diarrhea, or constipation, but it also will not help you until you gradually work up to enough of it in your gut, 24/7, to regulate motility.

In the meantime, everything else will keep impacting your gut and you will likely keep fluctuating day to day.

The Tummy Fiber is 100% soluble fiber, it can’t make anything worse, but it also will not help you with just the first dose or two, or first few days or two.

For constipation, it likely won’t help the first week or two either.

This is because you are starting at a low dose that won’t do anything at all — it is just to get your gut used to more fiber gradually.

All fibers are indigestible, so you always want to increase fiber slowly and steadily.

Do not skip doses.

Do not jump your dose up and then down and then up and then down.

Do not skip days – none of this will work.

This is a process. It can’t be erratic. It takes some time and patience, and you have to follow the process consistently, day in and day out, or soluble fiber will not do what you want it to do.

You need to start with just ½ teaspoon twice daily and then gradually increase.

Add an extra ½ teaspoon to just one of your doses, every 3–4 days.

So add an extra ½ teaspoon to your morning dose, wait 3–4 days, and then add an extra ½ teaspoon to your evening dose.

Wait 3–4 days, and then increase your morning dose again, etc.

You’ll keep following that pattern and gradually work up to the dose your gut needs for normal motility.

A rough average final dose for diarrhea is 1–3 tablespoons per day total.

For alternating diarrhea/constipation, probably 2–3 tablespoons per day total.

For constipation, a likely 3–5 tablespoons per day total.

That shows you the huge dose range, and also how far you will likely have to increase from the starting dose of just ½ teaspoon twice a day.

The fiber cannot make anything worse, but again, until you gradually work up to enough of it in your gut, it won’t help you either.

It has to reach the point where it can control your bowel motility.

You just will not have enough of it in your gut to affect you at all until you have worked your way far enough into the process.

I will tell you candidly — it will probably take you a few months to work up to the dose you would need to resolve chronic constipation.

In the meantime, you’ll still have symptoms, and you may need to use laxatives if you’re already doing that.

You should see improvements kick in as you gradually get your dose up around 3 tablespoons per day total.

Then you’d keep gradually increasing until you feel stable day in and day out.

You can’t just jump to this dose though – fiber does not work that way. I wish it did!

But you have to gradually get your gut used to more fiber, and then reach the point you need for motility regulation.

Once you hit that, you stay at whatever that dose is, morning and evening, as soluble fiber literally only works when it is physically present in your gut.

Yes, it does — but Acacia is not a laxative or a drug. It can work wonders for constipation, but it is not an overnight solution.

The way you take Acacia makes a big difference, and it’s worth the time and effort to do it right.

• Taking Acacia at a low dose for just a few days, then giving up because there’s no change
• Going from zero to the maximum dose in one week, then quitting because it “doesn’t work” and causes bloating or gas
• Starting Acacia at the same time you suddenly stop laxatives, enemas, or colon cleanses — leading to worse constipation

Start at a low dose (½ level measuring teaspoon twice daily) and increase gradually. Constipation typically requires a much higher daily dose than diarrhea, and it can take weeks or even months to work up to the dose you need.

Acacia is not a stimulant and will not give “overnight relief.” A low dose for a few days will not resolve constipation — the first step is simply getting your gut accustomed to more fiber.

Racing up to a high dose too quickly can overload your bowel, causing bloating and gas. If you have IBS, your GI tract and gastrocolic reflex are hyper‑reactive, so your goal is to keep them stable and calm.

Think of it like training for a marathon — you can’t sprint from the start without rest. Gradual increases allow your gut to adjust and encourage normal motility over time.

If you’ve been using laxatives or other motility stimulants (such as senna, cascara, aloe, enemas, or colon cleanses), your bowel may be dependent on them. Stopping suddenly can worsen constipation, even without Acacia Fiber.

Instead:

• Continue your usual laxative dose while starting Acacia
• Gradually increase Acacia until you reach 2–3 tablespoons daily
• Then slowly decrease your laxative dose while continuing to increase Acacia
• Take each step slowly to ensure success
• See here for full details on transitioning off laxatives...

For many people, transitioning from laxatives to Acacia takes 1–6 months, depending on bowel dependency. IBS is typically a lifelong condition, so investing a few months for a significant improvement is worthwhile.

With consistent, gradual increases, Acacia can help restore and maintain normal bowel motility for the long term.

Nope! What matters most is that you find a schedule that works for you.

It does not matter to your gut whether you take the fiber with food, without food, between meals, or right along with them. As long as the fiber is physically in your gut, it will help regulate motility.

The key is to start at a low dose twice daily and gradually work up until you reach the dose your gut needs for normal motility.

Your goal is to keep fiber in your gut 24/7, because it only works while it’s physically present in your digestive system.

The specific timing—whether with or between meals—is entirely up to you. Consistency is far more important than timing.

How to Start and Increase Your Tummy Fiber Acacia Dose

Begin with 1/2 level teaspoon twice a day (a daily total of 1 teaspoon).

Every 3–4 days, add an extra 1/2 teaspoon to one of your daily doses. Alternate which dose you increase so that you are going slow and steady.

Do not increase your dose too much or too quickly — your gut needs time to adjust to any fiber increase.

All fibers are indigestible, so suddenly or drastically increasing your dose can cause bloating and gas.

Keep stepping up your dose every 3–4 days until you gradually reach the amount that resolves your constipation and/or diarrhea.

• Everyone: start low, increase gradually, keep increasing till stable
• Constipation: usually resolves at 3–5 tablespoons/day
• Diarrhea: typically resolves at 1–3 tablespoons/day
• If symptoms resolve at a lower dose, stay there
• If you need more than the average dose, continue to increase gradually
• Maximum daily dose: typically 5 tablespoons/day

The maintenance dose varies for each person depending on specific symptoms.

The fiber will work regardless of how you take it:

• Added to plain water
• Sprinkled over moist foods
• Added to cooked foods
• On an empty stomach or with food

For best results, take the fiber right before or during a meal to help keep your gastrocolic reflex calm after eating.

How Soluble Fiber Acacia Senegal Helps IBS Diarrhea

The "soluble" in soluble fiber means that it dissolves in water (though it is not digested). This allows it to absorb excess liquid in the colon, preventing diarrhea by forming a thick gel and adding a great deal of bulk as it passes intact through the gut.

This gel (as opposed to a watery liquid) also keeps the gastrointestinal muscles stretched gently around a full colon, giving those muscles something to easily "grip" during peristaltic contractions. This prevents the rapid transit time and explosive bowel movements that are common with diarrhea.

How Soluble Fiber Helps IBS Constipation

By the same token, the full, gel-filled colon (as opposed to one clenched tightly around dry, hard, impacted stools) provides the same "grip" during the muscle waves of constipation.

This allows for an easier and faster transit time, and the passage of the thick wet gel also effectively relieves constipation by softening and pushing through impacted fecal matter.

If you can mentally picture your colon as a tube that is squeezing through matter via regular waves of contractions, it's easy to see how a colon filled with soluble fiber gel is beneficial for both sides of the Irritable Bowel Syndrome coin—diarrhea and constipation.

How Soluble Fiber Helps IBS Pain and Cramping

As a glorious bonus, normalizing the contractions of the colon triggered by your gastrocolic reflex—whether they are too fast or too slow—helps prevent the violent and irregular spasms that cause lower abdominal cramping pain, a hallmark of IBS.

Heather's Tummy Fiber: Daily IBS Support with Added Benefits

Best of all, Heather's Tummy Fiber Supplement can be taken daily and indefinitely with no harmful side effects or risk of addiction.

In fact, soluble fiber has health benefits far beyond managing IBS. It has been shown to:

• Lower LDL ("bad") cholesterol
• Reduce the risk of heart disease
• Minimize colon cancer risks
• Slow the absorption of fats and carbohydrates, improving glycemic control
• Prevent the formation of free radicals
• Help manage diabetes

If you’re new to soluble fiber supplements, start with a low dose of Acacia — ½ level teaspoon twice daily. This means a level measuring/baking teaspoon, not a utensil teaspoon used for stirring or eating. A utensil teaspoon is much larger, and a level teaspoon is about half of a rounded teaspoon.

Gradually increase your dose over time. You can work up to a maximum of about 5 tablespoons daily (measuring/baking tablespoons), divided into two or more doses. You don’t have to reach the maximum; if you stabilize at a lower dose, that’s fine.

Dosage Increase Tips

• Raise your dose by ½–1 teaspoon at a time
• Increase every few days or weekly
• Go slow — sudden increases can cause bloating or gas
• Constipation may take weeks to resolve, especially if chronic
• Diarrhea and spasms may improve within days as you increase

Aim for 15–25 grams daily (about 2–4 tablespoons), divided into two or more doses, to keep your gut filled with soluble fiber around the clock. This helps prevent bowel dysfunction and abdominal pain before they start.

Best Times to Take Tummy Fiber

While it works at any time, many find it helpful to take Acacia:

• On an empty stomach, first thing in the morning
• Before meals as a “buffer” to calm the gastrocolic reflex
• Before eating restaurant meals or high‑fat/insoluble fiber foods
• Before bed, if mornings are your worst IBS time

Clinical studies show Acacia increases beneficial gut flora, which helps reduce bloating and gas. It also has excellent gastrointestinal tolerance, meaning it’s less likely to cause discomfort compared to psyllium or inulin.

I’ve Been Stable, But Now I’m Flaring – How Do I Adjust My Dose?

Sometimes, diet changes, stress, or new medications can trigger IBS symptoms, even if you’ve been stable. If your usual dose no longer works, gradually increase your fiber intake until you stabilize again.

Add an extra ½ teaspoon every 3–4 days until symptoms resolve. The new higher amount becomes your maintenance dose going forward.

Is Tummy Fiber Acacia Senegal High Carb? Will It Make Me Gain Weight? Can I Take It If I’m Diabetic?

No — Heather’s Tummy Fiber offers all the benefits of soluble fiber without carbohydrates or calories your body can absorb.

While the FDA requires soluble gums like Acacia to be labeled as 4 calories per gram, they are not digested and do not contribute calories in practice.

Benefits for Diabetes, PCOS, and Weight Management

• Slows carbohydrate absorption to improve blood sugar control
• Lowers LDL (“bad”) cholesterol, reducing heart disease risk
• Helps stabilize blood sugar in PCOS
• Supports healthy weight management

What Does Raw Acacia Senegal Look Like? How Is It Made Into Tummy Fiber?

Heather’s Tummy Fiber comes from the all‑natural gum of the Acacia Senegal tree. The raw gum appears as gold or amber crystal‑like pieces collected from the tree’s exterior.

Processing steps:

• Dissolved in water
• Filtered and sterilized
• Gently dried on heated surfaces to evaporate water
• What's left is the fine white powder

No chemicals, bleaching, or hydrolyzing are ever used. Natural variations in grain size or color are normal.

What’s the Easiest Way to Dissolve Tummy Fiber?

• Stir directly into moist foods instead of liquids
• If using liquids, choose cool or lukewarm temperatures
• Add fiber to an empty cup, mix with just enough liquid to dissolve, then add more liquid
• Stir with a fork, not a spoon
• Let sit for 60 seconds after stirring, then stir again to remove lumps
• Sprinkle gradually on moist foods while mixing
• Add to smoothies in the blender
