(Last Updated on November 9, 2022)

The science around prebiotics and probiotics aren’t exactly new, but the supplements that help promote either or both differ in quality and value.

Truth be told, it’s difficult to determine which supplements are helping you from those that are just cashing in.

Could PrebioThrive be a wonder supplement or another marketing ploy?

What Is PrebioThrive?

PrebioThrive is hails from Gundry MD, a company founded by its namesake with the aim to significantly improve human health, happiness, and longevity. Or basically what every other CEO of a health supplement company says.

PrebioThrive itself is described as a cutting-edge formula, but we’ll be the judge of that.

  • Pro-gut benefits. It lists down the basics of what prebiotics can do.
  • Free of the nasty stuff. Good for those allergic to soy or hate sugar and artificial sweeteners.
  • Available in 3 sizes. 30 day, 90 day, and 180 day supplies.

How To Use It?

Take 1 scoop (10 g) in 8 fl oz of water every morning.

PrebioThrive Ingredients


Most of the ingredients are organic which means it’s good enough for people who don’t cater to GMOs and “Big Food” or for those who just like the idea of buying organic supplements.

Acacia gum

Used in a variety of products which range from supplements to lozenges and ice cream. Research has shown it to be better at increasing bifidobacteria and lactobacili than the same amount of inulin. It also seems to be not as bad on the side effects compared to other prebiotics too. Being the first on the list means this is the dominant ingredient.

Agave inulin

Inulin has been known to be a full-fledged source of dietary fiber for a long time now, but research has shown its potential as a good prebiotic mainly increasing fecal Actinobacteria and Bifidobacterium. It’s not as good as acacia gum, though.


Not exactly a prebiotic, but an ingredient that supports prebiotic ingredients.


Research shows this ingredient to be capable of enhancing growth of Lactobacillus and Bifidobacterium strains. It has to be high-purity, though, and we assume it’s not.

Guar gum

Studies say it’s capable of reducing symptoms of irritable bowel syndrome such as bloating. It has to be at around 6 g/day, though, and being in the bottom of the rung means it’s more of an accessory than a functional ingredient.

How Does PrebioThrive Work

From the get-go, PrebioThrive’s ingredients look promising. It does have research-backed ingredients that can help support prebiotic efforts.

The only problem we see is we don’t know the dosing for each ingredient, and when it comes to research-backed ingredients dosing is everything.

They started pretty good with Acacia gum and Agave inulin, although it would’ve been better (and much more efficient) if they omitted the latter and just pumped up Acacia gum.

Compared with the negative control the numbers of Bifidobacteria and Lactobacilli 4 weeks after consumption were significantly higher for gum arabic: the optimal dose being around 10 g. Moreover, at this dose the numbers of Bifidobacteria, Lactobacilli and Bacteroides were significantly higher for gum arabic than for inulin.

The study says Acacia gum performs at a much better rate than Agave inulin anyway, so why not just distribute the dose to what gives you the best bang for your buck?

We like the addition of flaxseed here especially if it’s in oil form. It doesn’t hurt to have an ingredient capable of augmenting other ingredients.

We also have no real complaints against their Galacto-oligosaccharides save for its purity or lack thereof, as the studies indicate high purity works best when it comes to prebiotic applications.

We would’ve omitted guar gum altogether and added the dose to acacia gum if only because the working dose for guar gum is clearly not provided in this formulation.

All in all, we think PrebioThrive has potential, but you’re gonna have to take more than 1 scoop to get the right benefits your body needs.

Even if 10 g sounds a lot, it would help to know that prebiotics work within that range as a minimum, with the smallest possible doses at around 6 g which are usually reserved for really high-potency ingredients.

PrebioThrive Benefits

There is definitely prebiotic potential in this supplement, and they do have the right ingredients despite poor formula design, but the questions are:

  • Will the 10 g serving be enough for the general population?
  • Will it be enough for you?

Guess you’ll just have to find out yourself.

PrebioThrive Side Effects

As with most prebiotics, gas and bloating are expected particularly during the first few days.

Good thing most of the ingredients here are reported to not have severe side effects if they do have them.

Customer feedback say they experience gas and stomach cramps, not to mention they say it doesn’t dissolve easily in water and tastes horrible.

Is It A Scam?

It’s not a scam in a sense that it has ingredients that tell us it’s a prebiotic supplement.

Whether it works or not is subjective to the user’s body.

PrebioThrive Reviews & Complaints

prebiothrive real users reviews

There’s a good mix of good and bad reviews, with bad reviews winning. Here are some of them:


As instructed, I add one level scoop to water and drink it in the morning, first thing before eating anything. If it has a flavor, it is mild. My waistline is slimmer and I no longer have tummy bloating or swollen ankles and fingers. Yes, I did experience gas at the beginning, but it went away.

Because I am following the eating regimen and exercising regularly, I believe that this supplement is just one component leading to these positive results. I am ordering my second supply and plan to continue using it along with following the eating plan.

Amazon Customer:

I noticed a difference within a few days of taking this, and cutting out Splenda, and using Stevia in my coffee. Sugar cravings are way down, so binging on bad foods is, too. I would have rated 5 stars, but the canister is small for the price, and filled half-way, at that. I will still buy it, for my health, but a full cannister would be a bettet cost value.

Scifi Reader:

I purchased this product through their website. The product does work, so I can’t be overly critical. However, for me it has made me extremely gassy. I now have long loud and smelly trumpeting going on back there. I have been using the product for over a month with the hopes that the backdoor renditions would begin to subside. Nope. In fact the trumpeting has increased like it is practicing for a new gig.

Merle K.:

I wish I’d read the negative reviews before I ordered $199, worth of this product. Dr. G’s online talk is so persuasive that I fell for it. I’m an MD myself and it made sense to me. The product doesn’t dissolve but creates an unpalatable suspension that can make you retch and gag. I was determined to push through the negativity and tried for two weeks, after which time I realized that the terrible cramps I was experiencing began right after beginning with the PreBioThrive. I stopped and two days later I am back to normal.

PrebioThrive Pros & Cons


  • Well-researched ingredients. We can’t say they’re not studied.
  • Hints of ingredient synergy. That added flax seed makes everything work better.
  • Savings on multiple orders. Up to $10/bottle savings + free shipping.
  • 90-day money back guarantee. It’s always good to have one in case your product doesn’t work.


  • Proprietary blend. We can’t tell how much of what is in this supplement.
  • Poor customer feedback. Overwhelming poor feedback would make anyone hesitate buying this.
  • Too good to be true commercial. Customers say the marketing team did a great job at making them buy a product that doesn’t work.

PrebioThrive Review: Final Words

Our PrebioThrive review fully explained both the pros and cons of this supplement.

We like the ingredients, the synergy, and the convenient savings per order the company advertises.

What we didn’t like are the numerous complaints and the positive reviews that looked to come from paid review writers.

There’s a good chance it will work, but the odds of it not working at all is just about the same too.

11 Replies to PrebioThrive Review: Does It Really Work?

  1. I have used it for about a week. Initially, I experienced some bloating, but that has dissipated. I agree that it doesn’t dissolve in water well enough; but frankly, I like the taste of it. It must be the flaxseed, as it reminds me of a cereal I used to eat.
    I plan on purchasing it as this supply diminishes.

  2. After sitting through the whole of the “spiel” which took best part of 45 mins I was ready to order. Went to order and was then told they only send to U.S. I wish they made it clear at beginning, rather than waste my time. However it did give me a chance to read reviews and sounds like there are better options out there.

  3. I’m trying the prebiothrive in hopes it helps my IBS!!! I’m So tired of this problem. I mix it with my vital reds (Gundry MD) which I drink every morning. Not bad tasting that way!
    The Prebiothrive should work, any way I sure hope it does. Will post again in a month or two and let you know my progress ?

  4. It helped relieve constipation and curbed my appetite effective the second day. No cramping no gas for me. This is going on my second week.

  5. I have been taking this for a month and a half and I’m very glad to say my food allergy has totally subsided and I can actually say I no longer have hives (which were occurring on a daily basis and despite allergy meds, I got very little relief). I definitely intend to continue with this product. I have no issue with the taste and I am totally off all meds!

  6. Also must add if your eating gmo food grains or your havin severe gut inflammation you must adjust your diet accordingly or any supplements will be canceled out. FYI

  7. I just got my order yesterday drinking a glass of it this morning haven’t had any side effects someone did tell me it does cause constipation, I’m hoping that doesn’t occur. I will be posting again as I take this product every day. Also does anyone know about the supplements that you can take that supposedly helps with this product?

  8. I’ve been taking this for just under 2 months. I am generally very skeptical about supplements. and only ordered this based upon feedback from friends. I was surprised by the outcome so far. I don’t crave foods ad before, an regular (wasn’t before), no longer have to take prilosec daily, and have lost 17 pounds since starting this 7 weeks ago. The lost weight isn’t just because of this product. I’ve been careful with my diet and exercising but this product seems to have made my diet easier. I love sugar, but now, no longer crave it, and don’t know why. So as long as it continues to work, I’ll keep ordering. Oh, I like the taste and I add a very small amount of “rich chocolate slimfast” powder to my morning dose which basically makes it my desert of the day.

  9. Thank you everyone for ur comments, I have mixed feelings if I should buy the product , I’ve heard all of ur pros and cons , I do want to eliminate Eating all the wrong foods , obviously all junk foods, but when he said tomatoes, nuts (cashews), beans ( garbanzo) , at the end of the day it’s BUSINESS, dr or not , I still haven’t met anyone who does or shares anything for free!!!
    One thing is for sure , exercise will weed out the weeds !!!!!!!
    If anyone knows and wants to share the goods From the Bads , I’m all ears ,eager to learn on what foods , vegetables, drinks , snacks are good for the body please share thank you guys !!!
