See why our customers love PrebioThrive so much.


I created PrebioThrive using five of the most potent and effective prebiotic ingredients available. It’s formulated to help you enjoy improved digestion and greater feelings of overall health and wellness.

Gundry MD PrebioThrive is formulated with purity in mind. The content of every batch is formulated right here in the USA at our CGMP-certified facility — and then tested again for content, purity, and dosage at an outside 3rd-party laboratory.

That’s why we’re confident PrebioThrive will help you achieve:

  • More efficient digestion
  • Reduced stomach and bowel discomfort
  • A more balanced gut microbiome
  • Boosted feelings of energy and vitality
  • sugar-free
  • artificial-free


The nutritious dietary fiber-rich ingredients packed into PrebioThrive – like acacia gum, agave inulin, flaxseed, and guar gum – contain powerful prebiotics.

Prebiotics, in fact, are the microorganisms that support the healthy balance of good bacteria in your gut. Our prebiotics contain a blend of dietary fiber to encourage digestive health and regularity.

In my opinion, most people just aren’t getting enough prebiotics in their diet, and that needs to change. PrebioThrive ensures that you’ll be getting your prebiotics in the right dosages to effectively make a difference.


I’ve put all my resources and research I’ve gathered throughout my long career as a heart surgeon and medical researcher into this unique formula — and I’m confident it’ll work for you just like it has for so many other people. I believe in this product so much, in fact, that I’ll put my reputation in your hands and make a deal with you:

Just try Gundry MD PrebioThrive for 90 days…

If you don’t feel a noticeable change in your digestion, and overall sense of health and wellness…I’ll give you a full refund.

That’s how certain I am that Gundry MD PrebioThrive will create a total health transformation.

If you don’t see incredible results, I’ll give your money back — and that’s my personal guarantee. Even if you’ve used up your entire supply and you’re dissatisfied — for any reason whatsoever, I’ll still return your money. My US-based customer support team will make the refund process fast, easy, and hassle-free for you.

This 90-Day Complete-Money-Back-Guarantee allows you to try Gundry MD PrebioThrive with zero risk involved.

Frequently Asked Questions

What are the ingredients in PrebioThrive?


How do I use PrebioThrive?

Start your day off right with a scoop of PrebioThrive in the morning. PrebioThrive is a dissolving naturally-flavored mix that tastes great in water and a variety of other beverages, including smoothies.

To experience the full benefits of PrebioThrive take one scoop daily with beverage or blended drink, preferably with probiotics to create a synbiotic effect. Use it consistently for the best results.

Who should use PrebioThrive?

This prebiotic supplement is designed to help support digestive health, and strengthen your immune system. It is perfect for anyone who wants to improve digestive comfort and feelings of wellness.

PrebioThrive is a supplement, and therefore, NOT designed to treat more serious illnesses. It should not be used to replace prescription medication.

How safe is PrebioThrive?

PrebioThrive contains only 100% natural and safe ingredients. The formula is tested for quality and purity at an independent, 3rd-party facility. However, as a physician I recommend consulting with your own health care provider before beginning any new supplement.

What if it doesn’t work for me?

We’re incredibly proud of our industry-best customer support and equally proud of our groundbreaking supplements, which is why we back up every single one of our supplements with our 90-day customer satisfaction guarantee.

If you’re unsatisfied with your results for any reason, simply contact our customer support team within 90 days of purchasing your products, and we’ll refund your purchase — no hassle, no worries.


Acacia Gum

Acacia Gum is one of the most fiber-dense prebiotic ingredients on the planet.1

Agave Inulin

Agave Inulin is an excellent source of dietary fiber. Fiber-rich Agave Inulin tastes sweet…while having minimal impact on blood sugar levels.2


Flaxseed is a great source of fiber and omega-3 fatty acids to help with heart health. It also has antioxidant properties to help protect against free radicals.3


Galacto-oligosaccharides are a prebiotic designed to improve mineral absorption and support your immune system.4

One scoop in my morning smoothie
Customer: Terri Faultersack

Everyday:) one scoop blended in with my morning smoothie.

Customer: Mattie

As long as I can remember, I have always had a problem with constipation. 2-3 days after I started taking Prebiothrive, I started having daily bowel movements. I can't tell you how wonderful it feels. Thank you Dr. Gundry. Your product worked exactly as you said it would.

Customer: Michelle A

I was not consistent at first but the past 30 days I have been steadfastly taking morning and evening along with following Dr Guidry food pyramid. My indulgences are getting less frequent the better I feel keeping in step with my Gundry regimine. Down 6 pounds and so much easier to say no to grains. Acid reflux has lessened amongst other ailments. Although it is the holidays I have a game plan to stick with it.

Dr Guidry, a question. Is there any downside to treating this product like tea and mixing it with boiling water. ''Tis cold in my neck of the woods and I quite like Prebiothrive warmed up for my morning commute. Will adding boiling water interfere with the desire effect of the product?

Vital Reds and ProBioThrive
Customer: Linda Morrison

I have been taking the above products for 2 1/2 months and I love it. I lost 12 pounds and feel wonderful! I mix the two together every morning and feel great when I get up in the morning. I recommend these products to everyone!!

Great Product
Customer: DrGeorge C Abraham

I take Vital Reds in the morning It is great my blood sugar is in control stays down The is the greatest product under the Sun.Thanks Dr Gundry.

Customer: Mike

I've only been drinking the PreBioThrive for 2 days so the morning before work and then in the afternoon around 4pm or so after work.
My feeling bloated has stopped already and cravings for sugary foods has certainly stopped as well!
I can't tell you how happy I am and how GREAT I feel already!
Have decided to get the PreBioThrive monthly and am SUPER EXCITED about this product and it's benefits for overall health and vitality.
I was skeptical at first to say the least with ALL the products out there that DON'T work!
Thank you Dr. Grundy for your hard work and dedication to helping we humans get our lives back!!

Prebiotic Helped my Acid Reflux
Customer: Kathleen

I have been mixing the Preboitic powder in my water with the Vital Reds for over a month now and my acid reflux has improved immensely.
Also started Dr. Gundry's diet and by not eating the certain foods in his book, my stomach is so much happier.
Glad I found you Dr. Gundry.

Customer: Meg

I took this for 1 month as a trial and really did notice a difference in bloating and my digestive health. I also noted less cravings throughout the day as well as not over eating. I have lost a few pounds as a bonus! Being a cardiac patient your product caught my interest. I want to find out more about your other products.

Customer: Jovonne Newby

I am a senior citizen and was having trouble regulating my intestinal track. It was usually constipation or too loose. I appreciate PREBIOTHRIVE! I feel I can rely on it.

Part of my successful weight loss
Customer: Michael D.

I'm satisfied that it does help reduce cravings for the wrong types of food.

Customer: Ruth

I ordered 3 months of this and I have never felt as much difference in a week and a half as I feel now.

Fantastic Customer Service!
Customer: Mrs. Baker

I watched the video on this product and got excited and ordered a bunch of canisters to take this! Once I received them, I found out that one of the ingredients is derived from milk. I have a milk allergy and even though it's a small amount in the product, I tried it and still had a reaction. I called customer service and Duane went above and beyond by apologizing that the product didn't work out for me then refunded me the entire amount! Outstanding customer service. Prebiothrive itself is high qualitiy product and I'm very sad that I can't take it because I had an amazing level of energy for two days when I tried it! If you have no issues with milk, I highly recommend this product to take every day for increased energy and health!

Great Product
Customer: Georgeann Alexander

I am currently on my second container of PrebioTHRIVE and can't believe the difference. I have IBS and the bloating, gas, etc. have disappeared. Could not be happier with the results. I also use vital reds and mix the two together and drink every morning. Love the energy and overall good feeling that I get everyday by using these products.

Customer: Mary Savage

I am on my second jar of prebiothrive.

Customer: John K

We have been using the supplements from Dr. Gundry for more than a month. Our experiences using the products have been excellent and our systems have been operating with far less effort thanks to the PrebioThrive and Plant Paradox recipes. Also, the increase in energy and alertness we've felt from the synergy of combining the supplements have made a positive difference in our lives. To summarize, we have lost weight and feel better. Thank you Dr. Gundry.

Customer: Kara Obana

I have been using the prebiothrive for a month and feel great. I don't feel as bloated as before and have more energy. I mix it in a morning smoothie but have also just added it to water and the taste is surprisingly pleasant.

Customer: Carol Stotts

I've been using Prebiothrive consistently now for about 3 weeks. At first, my stomach bloated a bit (possibly from die off?) but finally, in the past 2 days, it's flat again and I'm feeling healthy on the inside and having fewer sugar cravings. Worth the persistence!

Prebio Thrive
Customer: Bernard W. Merkle

Excellent product. It helps me to feel more healthy and fine every day. People at the gym I go to say I am looking more trim and active. I am feeling happy more often. So far the only problem I have with Prebio Thrive is remembering to take it each morning 30 minutes before I eat my breakfast but I will solve that little problem soon.
