Each year, roughly 37 million people[1] visit the doctor with digestive complaints. Digestive issues like irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), diarrhea, and constipation may not be life-threatening in most cases, but they can make life pretty uncomfortable. Enter Dr. Steven Gundry. 

Dr. Gundry, the founder of Gundry MD, has decades of medical experience and spent thirty years as one of the world’s pre-eminent experts in heart surgery. Midway through his career, Dr. Gundry experienced health problems himself that led him on a path to a new passion – gut health. In 2002 he founded The Center for Restorative Medicine where he has been studying the human microbiome. That research led him to the development of a line of holistic health products including the popular digestive supplement Bio Complete 3. 

Bio Complete 3 is a dietary supplement designed to support optimal gut health. Packed with prebiotics, probiotics, and post-biotics, this product helps support healthy gut lining and provides noticeable results such as improved regularity, weight loss, and relief from cravings. Made with all-natural ingredients, this supplement comes with a 100% money-back guarantee.

What is Gundry MD Bio Complete 3?

Dr. Steven Gundry is the mind behind a variety of wellness products including Bio Complete 3. Gundry MD products are backed by scientific research and made with natural ingredients. They’re also tested by 3rd parties to ensure safety. 

Bio Complete 3 is an all-inclusive dietary supplement formulated to support various aspects of digestive health. Roughly 70%[2] of the human immune system resides in the gut, so taking care of your digestive health is key for overall human health. By supporting healthy gut lining, this supplement also supports healthy weight management, reduces unhealthy cravings, and boosts energy levels. All through the use of natural ingredients. 

In the following video, Dr. Gundry will explain some of the most asked questions about Gundry MD Bio Complete 3:

Does Bio Complete 3 Really Work?

Using a 3-pronged blend of probiotics, prebiotics, and post-biotics, Bio Complete 3 works to support the entire digestive system and boost gut health. Prebiotics are special plant fibers that provide a food source for good gut bacteria in the digestive tract while probiotics are live yeasts and beneficial bacteria that support gut health. 

An ideal balance of these is essential for a healthy gut microbiome and can help resolve digestive issues better than probiotic supplements alone. In addition to supporting healthy bowel movements, this supplement supports overall immune system health.

Health Benefits & Safety

Gundry MD Bio Complete 3 is made only with pure and natural ingredients. The formula is based on years of scientific research, tested for purity and quality by independent third-party facilities. As is true for any dietary supplement, however, you should check with a qualified health provider before taking it. Your qualified medical professional can help you determine whether a probiotic supplement is necessary and what dosage is appropriate for you.

Bio Complete 3 Ingredients

With just two capsules of Bio Complete 3 twice daily, you may enjoy health benefits including weight loss, more energy, relief from junk food cravings, and improved regularity. 

Here is a list of the ingredients in Bio Complete 3: 

  • CoreBiome (1000mg)
  • Sunfiber (200mg)
  • Bacillus coagulans (16mg)
  • Microcrystalline cellulose
  • Hydroxypropyl methylcellulose
  • Silica
  • Magnesium stearate


Produced by Compound Solutions[3], Inc., CoreBiome is a tributyrin supplement. In fact, it is the top-selling post-biotic in the world and the only one supported by clinical data showing that it reaches the colon. The colon is where fermentation occurs[3] and it is where bad bacteria tend to proliferate. This supplement offers clinically proven bioavailability and there is an ongoing clinical study to show its ability to boost butyrate-producing gut bacteria.


Sunfiber is a form of partially hydrolyzed guar gum and a proven probiotic made by Taiyo International, Inc. Clinically proven[4] to help move food through the digestive tract, this soluble fiber supplement may help relieve constipation and diarrhea. It also acts as a prebiotic fiber, promoting healthy digestive tract flora to support a healthy immune system, healthy digestion, and strong overall health. It may even support appetite control[4] which can help with weight loss. 


A source of Bacillus coagulans[5], ProDURA is made by UAS Laboratories, LLC. This particular strain of bacteria has an outer shell that keeps it protected against harsh environments like the intestinal tract. When it encounters ideal conditions, it reverts to its active form to support better gut health. A 2013 laboratory study showed that ProDURA offered greater heat resistance than two other probiotics on the market.

Though you should still talk to your healthcare provider before taking any new supplements, Bio Complete 3 is generally recognized as safe. While the health claims made by Gundry MD haven’t been examined by the FDA, the ingredients in this supplement are FDA-approved. Sunfiber meets the FDA’s definition for dietary fiber and Tributyrin[6] is a common ingredient used by many food manufacturers in the U.S. 

When it comes to probiotic supplements like the Bacillus coagulans used in Bio Complete 3, every individual has a different reaction. Probiotics come with some risk for carrying harmful microorganisms but reactions are generally mild. If you experience stomach pain after taking Bio Complete 3, talk to your qualified healthcare provider. 


Generally speaking, Bio Complete 3 is a well-liked product that seems to provide numerous health benefits. In addition to regulating your digestion, this supplement may help you lose weight and could boost your body’s immune response. 

  • Made with natural ingredients
  • Tested by a 3rd party
  • Supports irritable bowel syndrome (IBS)
  • Promotes healthy weight loss 
  • 90-day money-back guarantee
  • No significant safety concerns


  • Somewhat expensive ($70 per bottle)
  • Ingredient list is somewhat lacking in specificity
  • Some ingredients have limited human testing (Tributyrin) 
  • Contains only one strain of probiotic

While Bio Complete 3 has great reviews and a loyal customer base, there are a few concerns worth discussing with your health care provider. Certain ingredients like Tributryin have been scientifically shown to promote digestive health, but many of these studies[7] were in animals rather than humans. There is also some concern that this supplement only contains one strain of probiotic and the ingredient list is somewhat lacking in specificity. 

Bio Complete 3 Customer’s Review

In order to have a better understanding of the product and whether it’s worth buying or not, it’s good to have an unbiased perspective on it. This is why we’ll be taking a look at various customer reviews.

1 Star Review

“This company does not deal in good faith. We placed our order yesterday…less than 24 hours later, I called at 7 am, pacific time. I asked to cancel the order and was told it was too late to stop the shipment. This means we will have to pay for shipping back the products. I cannot believe that less than 24 hours later, they are not able to cancel the order. Please do your homework and read all the negative reviews about this marketing company!!!”

3 Star Review

“I only gave 3 stars because it is difficult to tell whether it is helping or not. I am dealing with IBS, which is very painful, and how do I know what is helping and what is not? On the other hand, I am consistently losing weight without trying, so something is working in that regard. Of course, that could be because for a couple months I could not eat anything. 

I am on my second bottle, and I can say my appetite is getting better, and I am not as tired and worn out. It is the only probiotic I am taking, so maybe it is helping. Maybe I’ll have to come back and give it 5 stars. I can’t see any reason to give up on it at this point. It certainly is not making me any worse.”

5 Star Review

“My system is so incredibly sensitive to literally everything. I have tried other probiotics that have caused skin or stomach issues. Bio Complete 3 is different. Results manifested around the 1.5-month mark

My BMs became awesomely predictable (2x/day)

I had more energy–no more slogging up a flight of stairs

Far less bloat meant a trimmer midsection which had plagued me since my mid-40s

My skin looks amazing–clear and bright! I’ve been using Bio Complete 3 for over 4 months now. 

Paired with clean, lectin-free eating and exercise, I am looking and feeling the way I used to in my early 30s:) I absolutely love this product!”

All reviews are subjective but hopefully by seeing the reviews above you’ll have a better understanding of the good and bad things this product brings.

Final thought

Overall, Bio Complete 3 appears to be a decent product for overall gut health and it may provide other health benefits as well. We like that it contains prebiotics as well as probiotics, and it’s unique in that it contains post-biotics as well. The main concern is that the product only contains one strain of beneficial bacteria while other probiotics contain several.
