PrebioThrive Review – Will it Improve Your Gut Health?

PrebioThrive is a premium-priced prebiotic drink that aims to support your gut health with a range of prebiotic fibers.

Using ingredients like flaxseeds and acacia gum, PrebioThrive claims to improve your:

  • Digestion
  • Constipation & IBS
  • Emotional Wellness

And more.

Now, we’re used to seeing various claims with supplements of this kind. But PrebioThrive was formulated by none other than Steven Gundry, MD, which certainly caught our eye.

That said, we’ll have to look through the ingredient formula, as well as the benefits, dosage, and side effects to make a final verdict on this PrebioThrive review.

Pros and Cons

Here’s a quick look at the good and the bad things we found with PrebioThrive.


  • A few great prebiotic ingredients
  • May help with IBS and constipation


  • Can’t tell the doses, the ingredients are in a proprietary blend
  • Acacia gum isn’t our favorite prebiotic
  • It’s better to get flaxseeds from your diet
  • Expensive – $79 for 30 servings

Who Makes PrebioThrive?

PrebioThrive is made by Gundry MD. This supplement company carries the name of its owner, Dr. Steven Gundry. He’s a cardiac surgeon who’s known for posting videos and articles online to promote his supplement line.

Although PrebioThrive is the company’s leading prebiotic formula, they make a range of other general health & wellness products too.


The official website claims that PrebioThrive helps you with:

  • Digestion
  • Stomach Discomfort
  • Energy
  • Mood
  • Gut Microbiome

How Does PrebioThrive Work?

PrebioThrive uses water-soluble fibers that feed your friendly gut bacteria.

As a result, it helps your friendly bacteria multiply and grow stronger, which is thought to help with things like digestion and nutrient absorption.

The ingredient profile of PrebioThrive will best show us how this product really works.


The PrebioThrive formula consists solely of prebiotics.

These include both soluble and insoluble fiber which your gut bacteria feed on.

We have to admit, there are a few odd ingredient choices in there. This includes flaxseeds. Read further to find out why…

prebiothrive ingredients

Acacia Gum

Also known as Arabic gum. Acacia gum is made from acacia tree sap. It contains glycoproteins and polysaccharides and is used as a stabilizer in food products.

Acacia gum is a water-soluble fiber, and as such, your body can’t digest it. So, what benefits does it have for the body?

Well, when you eat acacia, it passes through your gut, where your bacteria feed on it.

One slight problem is that acacia gum isn’t just food for your friendly bacteria but other microorganisms in the gut as well. This makes it inferior to some other prebiotics. (1)

Agave Inulin

Agave inulin is one of our favorite prebiotic ingredients.

Agave inulin will pass through your stomach intact. It will end up in your intestine where it provides excellent nourishment for your gut bacteria.

While agave inulin is sweet, it doesn’t have a high glycemic index, meaning it won’t spike your blood sugar!

Plus, it’s great because it only feeds your good bacteria. While simultaneously starving the ‘bad guys’ in your gut. This results in a more balanced and healthier microbiome. (2)


Normally, flaxseed isn’t considered a prebiotic. Despite that, flaxseeds are an excellent source of prebiotic fiber. Providing a whopping 30g of fiber per 100g of flaxseed.

Additionally, flaxseeds are a great source of omega-3 fatty acids. Which makes them a fantastic general health ingredient. (3)

Most supermarkets sell flaxseeds though. It’ better to just have them in your diet – it’s cheaper and works better as well. A prebiotic supplement like PrebioThrive can surely do better than this!


Galacto-oligosaccharides are made of glucose and various galactosyl residues. They are produced through a chemical conversion of lactose.

According to research, galacto-oligosaccharides boost the growth of Bifidobacterium in your gut. This is a good thing, since Bifidobacterium is beneficial for your general health. (4)

We feel that almost every good prebiotic supplement should have this ingredient in it. And PrebioThrive clearly ticks that box.

Guar Gum

Guar Gum is a type of soluble fiber extracted from guar beans. It adds bulk to stools and acts as a laxative. Some studies show that it might help with things like IBS and causes less bloating than a placebo. (5)

All in all, it’s a solid choice in PrebioThrive.

Anything Missing?

By far our favorite ingredient in a prebiotic supplement is Inulin-FOS. Sadly it’s not included in PrebioThrive.

Inulin-FOS is a soluble fiber. Professional products like Performance Lab Prebiotic source it from the chicory root. Inulin-FOS derived from chicory root is shown to promote digestive health, appetite, and even mood via the gut-brain connection. (6, 7)

That said, we do understand that chicory root is a more expensive and higher-quality source of prebiotics than most other cheaper ingredients out there. Not every supplement manufacturer is willing to pay for it.

How to Take (Dosage Instructions)

PrebioThrive comes in a powder form. Which means you need to consume it as a drink. It’s a bit less convenient than capsules, but it’s needed due to the sheer size of servings.

The dosage directions suggest mixing 1 scoop of PrebioThrive with water, smoothie, or other beverage and drinking it. Ideally, it’s recommended to drink it together with probiotics to create a “synbiotic effect.”

It’s worth noting that you’ll have a hard time completely dissolving PrebioThrive. This is due to its fiber content, and is perfectly normal.

Side Effects of PrebioThrive

The side effects are certainly important to talk about in this PrebioThrive review.

As it turns out, we didn’t find any problems with this supplement. PrebioThrive should be safe for consumption for most people.

That said, if you have a sensitive digestive system, you might experience these side effects from PrebioThrive:

  • Nausea
  • Upset stomach
  • Diarrhea
  • Bloating
  • Gas

Now, these aren’t common side effects, especially in a supplement that uses as safe ingredients as PrebioThrive.

If you want to be on the safe side, it’s always best to start with a lower dosage. We recommend taking just half a scoop to see how you react. Then asses your tolerance from there!

Price And Value For Money?

If you’re looking to buy PrebioThrive, you’ll probably want to know about the best prices and where to get it.

One bottle of PrebioThrive costs around $80 on the official website. Even though they offer a 90-day money back guarantee, this is still poor value money in our experience.

When you compare this price with our current top-rated prebiotic supplement, Performance Lab Prebiotic which costs $30 per bottle, you get an idea of how pricey PrebioThrive is.

Even if it was a top-tier prebiotic (which it really isn’t), it wouldn’t be worth such as high price tag in our opinion!

PrebioThrive Review Conclusion

So, should you buy PrebioThrive?

Just by looking at the benefits, it certainly looks like a great deal. But the price is a big bummer.

Asking $80 for a prebiotic supplement means the product either offers something extraordinary, or it’s a bit of a ripoff. We’ll let you be a judge on that one.

The reality is that you can get a healthy dose of prebiotics from your diet, too. Eating plenty of green veggies and perhaps some legumes and whole grains (if you can tolerate them) will go a long way for your gut health.

If you do wish to bolster your diet with a quality prebiotic supplement, we feel there are better choices than PrebioThrive out there – for a fraction of the cost.
