What Is Prebiothrive?

Do you constantly experience food cravings? Do you find it difficult to control your eating habits, along with your weight?

If so, the Gundry MD Prebiothrive supplement promises to use a “breakthrough” combination of prebiotics to help the good bacteria in your gut thrive, while simultaneously reducing the number of bad bacteria.

As a result, we’re told you’ll be able to bring natural balance to your digestive system and experience increased energy, decreased junk food cravings, a healthier appetite, along with less gas, bloating, and discomfort.

To accomplish this, Gundry MD claims Prebiothrive features only 100% natural and safe ingredients and comes with no reported side effects.

The bottom line is that many of us don’t eat the foods we should, so our digestion and overall health can take a hit.

But is there anything found in Gundry MD Prebiothrive that can “completely revitalize your gut, no matter how out of balance it is”? Does it have some stiff competition, or is it really a “game changer”?

Stick with us and we’ll explore these—and many other—important questions.

What’s the Difference Between a Probiotic and a Prebiotic?

Probiotics are specific strains of bacteria that can help improve digestion, boost immune system response, and more—although there’s limited evidence that they can help you lose weight.

And if your digestion is much more effective and you’re feeling good, this can translate into secondary benefits like improved energy.

On the other hand, prebiotics are a form of fiber that can’t be digested by your body, so they pass into your gut mostly intact, where they can act as a food source for probiotic bacteria. In other words, it helps them thrive.

Although most prebiotics don’t focus on a specific bacteria strain, in order to meet the definition they must increase the number or activity of bifidobacteria, a bacteria “family” often associated with improving constipation, reducing total cholesterol, addressing some aspects of IBS, and more.

How Gundry MD Prebiothrive Works and Their Ingredients

Prebiothrive claims to improve digestion, reduce stomach discomfort, promote a balanced gut microbiome, and boost energy. The company website advises taking 1 scoop of Prebiothrive every morning with 8oz of water, preferably with a probiotic to create the “synbiotic effect”.

The effects are thought to be possible through their blend of the following prebiotic ingredients:

Acacia Gum

This nondigestible polysaccharide has had various purposes in many cultures over the span of centuries. It is thought to promote wound healing, relieve pain, and support oral health in addition to the proposed dietary benefits.

In 120 healthy women, those randomized to treatment with 30g/day of acacia gum had a significant reduction in BMI and body fat percentage over 6-weeks.

Acacia gum supplementation at 10g/day over 4-weeks boosted the friendly gut bacteria bifidobacteria and lactobacilli in healthy volunteers more than an equal dose of inulin.

Agave Inulin

Inulin from the blue agave plant offers a rich source of fiber.

Obese adults experienced reduced hunger, desire to eat, and food consumption when randomized to inulin supplementation of 12-weeks when compared to controls.

Inulin supplementation in constipated adults at 12g daily for 4-weeks promoted softer stools, increased stool frequency, and increased amounts of 3 different friendly gut bacteria.

In 40 subjects with prediabetes, those randomized to 30g/day of inulin over 4-weeks reduced insulin resistance.


Offering a rich source of both fiber and omega-3 fatty acid, flaxseed is thought tobenefit heart, bone, and mental health.

In healthy adults, 50 g flaxseed/day over 4-weeks increased bowel movements per week by 30%.

In a review of 45 randomized studies, various dosing regimens and delivery method of flaxseed were used: whole flaxseed ranging from 13 to 90 per day, flaxseed oil ranging from 1 to 15.4 g per day, and lignan ranging from 50 to 600mg per day.

They concluded that whole flaxseed supplementation can reduce body weight, BMI, and waist circumference, particularly in overweight individuals.

Galacto-oligosaccharides (GOS)

GOS are indigestible fibers found naturally in mammalian milk that are thought to boost friendly gut bacteria and aid digestion.

In overweight and obese subjects, those randomized to 15g of GOS daily for 12-weeks experienced increased fecal Bifidobacterium.

A mixture of α-galacto-oligosaccharides at 5g daily boosted friendly gut bacteria in healthy adults, while it improved bowel function in constipated subjects.

Guar Gum

Guar gum is a gel-forming fiber obtained from the Cyamoposis tetragonolobus L. plant.

Guar gum was not an effective means at preventing diet induced obesity in mice. A review of 20 trials found that guar gum was not effective in reducing body weight.

In middle-aged women with elevated cholesterol, 15g of guar gum daily significantly reduced body weight but not cholesterol levels.

In constipated adults, 5mg of guar gum daily over 4-weeks significantly reduced colon transit time and the number of bowel movements with straining, while also improving stool form.

The Takeaway:

Prebiothrive’s blend of prebiotics does contain ingredients that have some available research.

Acacia gum may offer weight loss benefits, while also providing the ability to boost friendly gut bacteria better than inulin.

Inulin may offer weight loss benefits, reduce constipation, and decrease insulin resistance.

Flaxseed may similarly offer weight loss reduction and improve bowel function.

GOS may boost friendly gut bacteria in healthy and obese adults, while also aiding with constipation.

The weight-loss benefits of guar gum are mixed, though there may be a role in improving bowel function.

These effects have been investigated in a wide variety of dosing regimens and methods of delivery (powered, tablets, etc.). This, when coupled with the fact we do not know the amounts of each ingredient in Prebiothrive, makes it challenging to draw conclusions regarding the efficacy of this product.

Prebiothrive’s Potential Side Effects

Acacia gum was safe at 10g/day, though gas and bloating is described. Inulin was safe even at 30g/day. Flaxseed at high doses and in various methods of delivery is generally safe, though diarrhea and stomach pain are possible.

GOS and guar gum at 15g daily did not have serious adverse effects.

The vast majority of research ranges from 4-24-weeks, so we don’t know the long-term effects of these ingredients.

While prebiotics are generally safe to use, there is a risk for mild gas, bloating and cramping. These symptoms are easily alleviated with reduced dosing or discontinued use.

How Much Does Prebiothrive Cost?

How much you’ll pay for Prebiothrive largely depends on where you purchase it. For example, if purchased through Gundry MD’s SilenceYourCravings (landing page) URL, you’ll pay:

  • 1 Jar: $29.01
  • 3 Jars: $132.00
  • 6 Jars: $199.00

On the other hand, if purchased directly through the Gundry MD main site, you’ll pay:

  • 1 Jar: $79.00
  • 3 Jars: $222.00
  • 6 Jars: $414.00

Note: While it appears each jar of Prebiothrive contains 10.16oz of powder, there’s no indication of how many scoops this contains—or how often you’ll need to reorder.

Nonetheless, Prebiothrive comes with a 90-day money back guarantee, less S&H charges. In order to request one, Gundry MD’s customer service department can be reached at (800) 852-0477.

A Look at Customer Reviews of Prebiothrive

On Gundry MD’s main website, Prebiothrive has over 600 customer reviews and an average rating of 5 stars. There, common compliments referenced effective results (better overall health, increased energy, a more balanced gut, etc.) and ease of use.

Here on HighYa, as of December 2019, 426 customers left their review for a combined rating of 4.2 stars.

We’ve also written about many of Gundry MD’s other popular products, including Vital Reds, Total Restore, Primal Plants, and more.

Overall, these products tend to have very positive reviews from customers here on HighYa, largely with 5-star average ratings and many of the same compliments.

On the other hand, what few complaints there are seem to reference misleading billing and ineffective results. In most of these instances, a company representative responded in good faith to try to rectify the situation.

The Bottom Line: Can Gundry MD Prebiothrive Reduce Your Cravings?

The prebiotics included in Prebiothrive may benefit your digestion, friendly gut bacteria, and BMI. While the dosing in the studies that support these benefits vary greatly, we do not have information detailing the amount of each ingredient in this supplement, however.

This makes fully defining the safety and effectiveness of Prebiothrive difficult.

According to Dr. Gundry’s Prebiothrive video, taking a probiotic along with this supplement can maximize results..

Prebiothrive may be an expensive first-step for these reasons.

You can find many supplements containing both probiotics and prebiotics in the same formulation (although not from Gundry MD), which might deliver the ultimate bang-for-your-buck.

In the end, though, Gundry MD seems to stand behind Prebiothrive with a 90-day refund policy, and the product contains hundreds of positive customer reviews at HighYa which might help ease some of your hesitations if you’re thinking about giving it a try. Just remember you could be out a few bucks in S&H if you decide to process a refund.

  • Good for gut, bad for vocal cords.

    Took the probiotic powdered supplement for three weeks, and began having vocal issues. Initially, I suspected my vocal issues were related to sinus issues associated with the common cold, which I'd had around Thanksgiving.

    I continued to take the supplement and my vocal issues worsened. It's as though my larynx was coated with glue and would not expand. I went to an ENT specialist and had my larynx scoped and was told everything looked normal.

    I have always noticed that the supplement never completely dissolves with water and I have to chase it down with additional water.

    I take the supplement usually around 4 AM each morning when I first get up and I do believe it has definitely helped my digestive tract.

    I stopped taking the supplement on February 6th and have noticed a slight improvement in my range. I've always had a hi tenor voice but now I'm straining to reach the upper G in the bass clef and sound like Alfalfa.

    I'm the music director at my church and appreciate any feedback from you concerning any other reports associated with vocal issues.

    Kindest regards.

    I drink one scoop in hot water (cup) each morning around 5:50-6:00 am. I drink a second cup of green tea or vitamin-infused coffee (Vita Cup) with a vitamin D3 and a Garcinia Cambogia pill. Sometimes add a small avocado eaten out of its shell.

    I am full until after 1 pm.

    I’ve lost five lbs in about eight days. I feel great.

    I concentrate on high fiber low carbs as a recent lab test said my A1C is 7.4. Shocker!

    I have no history in my family, parents or grandparents of diabetes. I am 71 and 215 lbs. 5’2” so there’s that!

    I started changing my food choices and portion over two years ago and started at 267 lbs to get serious. I read about others losing 30lbs/mo. I am envious but not discouraged.

    I will next (I am on retirement pension) try your Lectin Shield product.

    Would tell my friends about it. Have it in my coffee in the morning. I have IBS, seems to help it. Mixes with coffee very well. Have a friend who told me about your product. And also ordered your book. She lost weight on your book and looks great. I noticed her weight loss in about 2 months. Asked her what she was doing and told me about the book. She gave it to me to read and after I read it and what it did for her I got very interested. So I looked up your site and looked at your video and became very interested in it. Like your advice on your site and recipe to makeup and the advice you give out on your website. Thank you for your product.

  • Noticeable changes

    I started using Prebiothrive to test it out so I can suggest it to my husband and daughter who suffer from frequent indigestion. I rarely had stomach problems but decided to try it out. Once I started using this product, almost immediately I noticed less pain in my joints and was waking up being able to move with greater flexibility. The powder is a little heavy and you have to mix it a lot to have it dissolve completely. Still, I got used to the taste and the consistency, and I ended up licking the spoon and scraping the residual from the glass. My husband has been a little skeptic about it and has not decided to try it. My daughter did not like the taste. Still I think it is a good product. The only negative thing I can say about it is that I have more gas, and sometimes it makes noise in my abdomen, which is a little embarrassing. I bought two cans and finished them last week.

    Also last week, I started using Vital Reds and I think they are FANTASTIC. I am feeling A LOT MORE energy and vitality. I feel less sluggish, although I think I am experiencing lower blood pressure at the same time.

    This week without Prebiothrive I think the noises in my belly have decreased. I am considering using Vital Reds alone to see how it goes, but will be on the lookout to see if the joint pains come back in the mornings.

    After taking the Prebiothrive I feel lighter after just a few days. My clothes are not as snug. I'm not experiencing any bloating as usual. I would recommend to everyone and everybody that experiences bloating and gas excessively. My food seems to digest better while taking the product.

    I use Prebiothrive every day in the morning as my first drink of the day. It blends best in a Bullet or Ninja blender instead of manual stiring. It truly is tasteless and curbs my appetite and regulates my BM daily with easier elimination. I have lost 3 lbs after 2 weeks of consumption. I truly feel good and energized with Prebiothrive in my daily routine!

    I use it daily in my protein shakes and now my bowel movements are working again and I have more energy. It is a good product for my morning smoothies, and I tried it plain and I did not like it. Then I added my vanilla protein powder, then I was able to drink it without putting it in my smoothie drinks. I use my own probiotic prunes that I eat.

    Dear Dr. Grundy,

    This product is so effective for me.

    I haven't had to change anything, just drink this every morning.

    My skin is clearing up and looking better. I notice that I am starting to decrease fat around my stomach area in a short period of time. I feel less tired and don't feel the need to eat between meals.

    In the 2 weeks of using Prebiothrive, I can honestly say I am feeling really good about myself and my body is getting leaner.

    Thank you very much for developing this wonderful product.
