I created PrebioThrive using five of the most potent and effective prebiotic ingredients available: acacia gum, agave inulin, flaxseed, galacto-oligosaccharides, and guar gum. 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


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, called probiotics, in your gut. Probiotics exist and proliferate in your gut, but probiotic supplements (such as Gundry MD™ 24 Strain Probiotic) are available to protect that healthy probiotic bacteria against digestive dangers, including the modern American diet, antibiotics, and certain environmental factors. PrebioThrive, my prebiotic supplement, supports the balance of probiotic bacteria with a blend of dietary fiber to encourage digestive health and regularity.

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

1 Acacia Gum

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

2 Agave Inulin

Agave inulin comes from the blue agave plant and is an excellent source of dietary fiber. Fiber-rich agave inulin tastes sweet…while having minimal impact on blood sugar levels.2

3 Flaxseed

Flaxseed is one of the great prebiotic foods readily available. It’s 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

4 Galacto-oligosaccharides

Galacto-oligosaccharides (GOS) are a group of carbohydrates that are used to improve bowel function. These prebiotics can improve mineral absorption and support your immune system.4 Some prebiotic foods rich in GOS are beans and lentils–but due to their high lectin content, it’s advisable to get GOS from the best prebiotic supplement available.

5 Guar Gum

Guar gum is a fibrous substance made from guar beans. Guar gum can increase fiber content in some foods and help maintain regular bowel movements.5

    I am 82 year old. I started using PreBioThrive about three weeks ago in hopes of raising my energy level. You said to not expect results before the first month, but I am feeling more energy already, to my surprise. I look forward to increased energy and my tiredness levels diminishing. I am using all three of your products and I am pleased with the results. Thank you.
