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

Guar Gum

Guar Gum is fiber from the seed of the guar plant.

Pribio Thrive
Customer: Amanda FS

I have been enjoying taking Pribiothrive for the past couple of weeks and have noticed that I have a significantly better mood and greater energy during the day. That said, I began taking Vital Reds concurrently so I'm unsure if which or both mixes are to be given credit.

Review of Prebiotic supplement
Customer: Barbara Nieman

I have been taking PrebioThrive for almost a month now. It has given me more energy and now I am able to complete more of my exercises. Prebiothrive has been very good for me which has really surprised me. I had a hip replacement last year and really was exhausted and didn't have the energy to do much. I am going to keep using Prebiothrive daily! Thanks so much!

Prebio Thrive
Customer: Tom Morgan

I gave the product 5 stars because within 2 days of use I had a fantastic bowel movement causing my stomach to feel 100% better. Not positively sure this is due to the product, but the next day I had another very good movement. I am convinced your product regulated my digestive process in such a way as to make it more efficient. I feel much better after 4 days of use will continue to use this product. My diet is not great and my stomach hasn't always felt good until using your product. So far I am very happy with the results.

Miracle! Not craving sweets or carbs!
Customer: Katherine

The most amazing thing about this product is that within 3 days, I was NOT craving sweets or carbs. I couldn't believe it! Before I started Prebio Thrive, it was almost as if I was COMPELLED to eat every starchy or sweet thing I saw. If I didn't give in, I was miserable, wanting to eat them, thinking about them longingly. Now, it's like those things are not even on my radar. For me, that is nothing short of miraculous!

Was skeptical if the product would work as good as described. However I am pleasently suprised that it works better then advertised! I love mixing it with the Vital Red's powder!
