Gundry MD Bio Complete 3 Review [OVERPRICED SCAM?]


I have recently came across Gundry MD's Bio Complete Probiotic 3.

It was a popular Probiotic in 2021 so I wanted to take a look for myself. 

This Bio Complete 3 Review will expose the honest truth on this Probiotic.

Keeping reading till the end to find out whether or not you should buy it.

What Is Gundry MD?


Dr. Steven Gundry

Bio Complete 3 Probiotic is a well-known probiotic dietary supplement from Gundry MD.

Gundry MD was started by Dr. Steven Gundry with the single mission to dramatically improve human health, happiness, and longevity through his unique vision of diet and nutrition.

Dr. Steven Gundry is a trained cardiac surgeon and served as the Head of Cardiothoracic Surgery at Loma Linda University, California, until 2002. 

He has worked as a cardiac surgeon for more than 3 decades and decided to launch Gundry MD after seeing how several hopeless cases were able to completely recover from severe ailments with just a change of diet. 

Gundry MD is known for its dietary supplements, including probiotics, protein supplements, skin care serums, superfoods, etc. In this article, I will provide an honest insight into the Bio Complete 3 probiotic sold by Gundry MD.  

Bio Complete 3 Ingredients

Bio Complete 3 contains a healthy blend of Bacillus Coagulans, sunfiber, Tributyrin (Corebiome™), microcrystalline cellulose, hydroxypropyl methylcellulose, silica, and magnesium stearate.

Bacillus Coagulans is a natural gut bacterium that is similar to the likes of lactobacillus and is used for treating diarrhea, irritable bowel syndrome, inflammatory bowel disease, and several other digestive conditions. (1)

Sunfiber is a brand of soluble dietary fiber developed and sold by Taiyo International, which works as an excellent prebiotic. (2) Each serving of 4 capsules contains 2 billion CFUs of Bacillus Coagulans. 

Bio Complete 3 contains short chain fatty acids that are found in a lot of fruits and vegetables. They help nourish your gut allowing good gut bacteria to thrive.


Bio Complete 3 Side Effects & Safety

Most of the ingredients used in Bio Complete 3 are considered safe and are also found in other probiotics and dietary supplements. Not many other probiotics contain Tributyrin, and the addition of this triglyceride, which is also found in butter, sets Bio Complete apart from other similar probiotics.

Tributyrin is a precursor to butyrate, and several studies have shown how it helps in reducing inflammation and insulin resistance associated with obesity. Another study discussed the positive effect of butyrate on immune system functions. Tributyrin is used as a dietary supplement, and Bio Complete 3 offers an unmatched combination of Probiotics, Prebiotics, and Tributyrin.

Bacillus Coagulans has been long used and is safe and beneficial for the human gut. Another study found this bacteria may help reduce inflammation and immune response, which often causes the inflammation in the first place.

The effect of Bacillus Coagulans on arthritis and other joint and muscle conditions has also been studied. There is plenty of evidence out there to suggest that Bacillus Coagulans is entirely safe and can help you with several health conditions ranging from inflammation to joint health.

There are some reports of side effects like Stomach Pain, Chills and Bloating with Bacillus Coagulans. (3)

Where to Buy & Pricing

The only place you can buy Bio Complete 3 is from the official website here. They don't sell Bio Complete 3 on Amazon. Anything listed on Amazon is from a reseller and not safe.

The company lists the price at $69.95 for a single bottle of 120 capsules (30-day supply).

You can, of course, save significantly if you buy multiple bottles as buying 3 bottles at $188.85 will lead to savings of $21, while 6 bottles are priced at $353.70, resulting in savings of $66.

Gundry MD offers free shipping within the US on all orders above $60.

BioTrust Pro X10 a similar product also has a similar bulk pricing model.

These prices may seem a bit higher when compared with other probiotics. Still, you must not forget that this is a higher quality probiotic compared to your other regular probiotic products as it has a combination of Prebiotics, Probiotics, and Tributyrin.

Gundry MD also has a 90-day money back guarantee, which I feel is  generous as most other similar products come with shorter guarantees of 30 or 60 days.

Bio Complete 3 Weight Loss

Gundry MD claims that Bio Complete 3 can make belly fat easier to lose.

The way they claim Bio Complete 3 can help with weight loss is by boosting butyrate levels and helping with symptoms of leaky gut.

Supposedly this can help with cravings for unhealthy food.

In my experience trying many different Probiotics, they can help for weight loss. The caveat to that though is they are a not "magic pill" and won't do all the work for you. 

You still need to eat a healthy diet and exercise.

Bio Complete 3 Reviews

Most reviews left by past customers of Bio Complete 3 are positive, and I will be sharing some of those Bio Complete 3 Reviews with you now. 

D. Eason says that he felt significant improvement in his longstanding digestive issues after taking 4 Bio Complete capsules a day for a week. He also cautions that a person needs to take the recommended dosage of 4 capsules and not 1 day for the maximum benefit.


Claudia Gerst mentions her own experience of suffering from an autoimmune disease called Proctitis, an inflammatory bleeding condition, for the past 5 years. She mentioned how she decided to take Bio Complete 3 after every other medication failed and how she could notice the results within 3 days, and then the condition disappearing. 


Another customer wrote how he cured his constipation by using the Bio Complete 3 capsules for a few weeks. 

Like any other probiotic supplement, Bio Complete 3 does not work for everyone, and I also came across several negative reviews where customers complained of gas, bloating, and indigestion which is also common with other probiotics.

Some unsatisfied customers complained that they did not see any improvement in their conditions after taking Gundry Md's Bio Complete 3.

  • Thank you for your review.

    • Alicia Harper

      Hi Miss T, Thanks for commenting 🙂

      • Stephen L. Stratton

        I bought 3 bottles but was forced to discontinue due to abdominal cramps. Reducing to one capsule per day did not improve matters.

        • Alicia Harper

          Hi Stephen, I’m sorry to hear that but thanks for sharing. Please consult a medical professional if you experience any side effects asap.

  • Have been taking BC3 for 3 months. Has helped with my bowel movements (BMs). He requires you to take a full 8-10 ounce glass of water with the pills. I still had some hard BMs. Found a suggestion at another website that said drink 2 glasses of water in the morning to get your BMs going. Have been doing that for a week and BMs are now soft. It is more than a probiotic and worth the difference.


    • Alicia Harper

      Hi Roseann, Any updates on your experience?

      When I take BC3, I take 2 in the morning and another 2 in the evening before I sleep 🙂

  • Hector R. Corrales

    Ms Harper I want to thank you very much for taking the time to produce this info on Steven Gundry as I get adds from him constantly on my iphone since I listen to YouTube lectures all the time throughout the day. I am partially deaf so I have the advantage of listening to lectures on various topics throughout the day through my iphone connected to my hearing aids. Dr. Gundry is on all channels that I listen to so I imagine he is spending great quantities of money on advertising. I think that this product is very expensive. But I have been thinking about purchasing Total Restore instead of Bio 3 since I have so many problems in the morning with bowel movements. My biological clock wants to eliminate in the morning but it seems that no matter how much I push I end up getting of the toilet frustrated because I can feel the urge in my colon but cannot eliminate. This is causing me a lot of distress. Now you seem to give Bio 3 positive marks but you have stated that you have tried 27+ probiotic products. In this article you do not tell me which product you prefer. So please tell me which product you use at this time 3/16/2021 since you tell me that you have found something useful to cure all of your ailments.

    • I like this product but I also take liquid calcium with magnesium citrate and vit. D from Puritans Pride. I buy in bulk because it has also helped friends and family with your same issue. It doesn’t taste bad and I only take a swig before bed and I’m good to go as soon as I eat in the morning (or sooner). I hope this helps because I know very well how you feel.

    • Alicia Harper

      Hi Hector, I like Live Conscious Pro 45 a lot but also enjoy cooking my own probiotic-rich foods these days 🙂

      • Alicia, I think what Hector might be hinting at is by not seeing the reviews on the other probiotics, might there be a conflict of interest with Dr. Gundry’s product. In other words is this a paid advertisement for the Bio 3 products?

        I think a lot of people look for some kind of ranking: My #1 is, #2 is… but to Hector, I say this:

        Ms. Harper has created an avenue for other real people to chime in about their results with not only Bio 3 but other probiotics that work for them. I would not suggest trying 27 probiotics if you don’t have to but try a few for 30 days and see.

        And even if there was a ranking readers will still get the feeling that the #1 spot is a paid ad. This is why those YouTube Day 1 and so on videos are so effective because we get to see the entire process for the most part.

        As a person in phrama research, remember it takes about 21 days for a substance to really start to take effect in your body so give things a chance, don’t be quick to judge something after the first use unless you break out in hives which is a sign of an allergic reaction. Sometimes if you feel nauseous that could just be a sign of how toxic your body really might be and those good bacteria going to battle with the bad ones but after a few days this too shall pass.

        By the way my #1 choice of probiotic is:
        Garden of Life RAW Probiotics, because you can get the up to 100 billion and 33 different strains in one to two capsules. I also do not trust probiotics that aren’t refrigerated. The cool keeps them potent and alive.

  • Would like to try this i suffer from a lot these systems but can not afford high dollar products. It sad we live in a money hungry world.

  • I’ve been using this for two weeks, my cravings have gone away, my ibs has reduced. I’m losing inches and weight. I thought this was a gimmick and never order but told my sister who is a physician about my many digestive issue and had gotten a Webber natural probiotic, but it made me feel a bit nauseated. so she sent me a bottle of these and these are the best I’ve tried to date. my bowel movement is regular and smooth. No bloating when i eat dairy. I would highly recommend these

  • I’d like to know of all the probiotic/prebotic blends you’ve tried which you believe to the best. I started Bio Complete 3 and didn’t like it at first. But then something in me remembered that I felt more energy so I went back to the bottle I left and started again, and had the same result. I was dragging and then I wasn’t. I’m going to order more but I’d be interested to know which you recommend most of all… and to be sure you are 100% non-biased in every way. Thank you!

  • I need Bio Complete 3 while I am in Indonesia, can I be given advice to have it …?

  • Should you take all four pills at once or split them up?

  • David S Holzboog

    Does this product contain soy? I ask because I am allergic to soy.

  • Hi,
    I have noticed that a lot of people talk about this being helpful with constipation. I have IBS-D. Do you have any suggestions on what the best types of probiotics are best for diarrhea dominant IBS, and reviews from people who’ve been helped by certain ones. I was taking Seed Probiotics for 3-4 months and stopped because they didn’t seem to help my gut. I just started taking Florastor a few days ago, too early to tell if its going to make a different yet!
    Thank you

    • Alicia Harper

      Hi Janelle, I can’t give any health advice, unfortunately. But I am in the process of writing some guides on individual probiotic strains and what the scientific studies say each seperate strain may or may not help with.

  • I tried using the promo code u suggested but it is not working. I tried to use it for the single bottle purchase and also a three pack but neither seem to work for me . Any other ones that will work? Thanks

    • Alicia Harper

      Hi Samantha, I just tried clicking through my best price button and using the coupon code thanks10 & it worked for me. Can you maybe try again? 🙂

  • Rosemary Grundy

    I don’t understand why there is nothing in any of the established Peer Reviewed Journals ( for example JAMA, British Journal of Clinical Pharmacology, Journal of Applied Physiology Nutrition and Metablolism) about this product.

    Has it been through any sort of independent double blind clinical trials?
    Has Dr Gundry submitted his research to any peer reviewed journals?
    Has it been through the rigorous approvals required for a approval as a pharmaceutical product?
    Or has it only passed the “not actually dangerous” test required for a food product.?


    • Hi Rosemary, You are right there are no Peer-Reviewed Journals for the Bio Complete 3 product, Only customer testimonials.

      What are your thoughts on the published studies for Bacillus Coagulans & Tributyrin (two of the main ingredients) ?

    • What’s your point? This is NOT a pharmaceutical.

      • Her point is to see if there is any scientific evidence or neutral experts who have reviewed it, to back up the many claims made. Why would you not want a medicinal product to be peer reviewed?

  • I purchased 12 bottles so that I could give them to people in my congregation that were having digestive issues. Only one friend had cramping and stopped taking them, everyone else has done well with them. They are expensive but if they can help a friend and you have the means, consider it a blessing to be able to give..

  • I’m ALWAYS tired, sore, feeling sick and weak. I’m 35! I hate this. I only
    Use the bathroom 2 times a week. I diet but I still
    Feel yucky! Can this help? Is there any coupons available? Thanks

  • Hey Alicia, I was skeptical and wasn’t going to order until I read your review and the comments posted herein. I ordered today. I also found a coupon code (SORRY15) that worked and gave me 15% off as a new first-time customer price of $49.95 for 1 bottle. With tax, I only paid $42.14. Oh, I also chose to subscribe. Wish me luck!

    • Hi Will, That’s awesome, and thanks for sharing the coupon. It looks like one they give out whenever they make a mistake lol!! Good Luck and I would love to know how you get on <3

    • Thanks for the Sorry code, it worked! Hope the product does. Worth a try for sure. I’ve been struggling with gut repair for ages & don’t even eat lectin foods. Sigh. Tbd…

  • Thank you for this information, Ms. Harper. I am curious if you receive compensation for your positive review or for posting a coupon for Bio Complete 3?

    • Hi John, is supported through my savings. I may earn a small commission on probiotic purchases made through my links.” This statement is in the footer.

      Affiliate Disclaimer: I am an affiliate of the Gundry MD Ambassador programme. I may receive a small commission through any purchases you make. (at no extra cost to you).” This statement is inside the review.

  • Are Gundry MD and Biotrust related? I have products that I thought were Gundry MD that say Biotrust on the package.

  • Julie K Dykstra

    I tried the discount code but it does not work.

    • Alicia Harper (Nutritionist)

      Thanks for letting me know, Julie! Looks like GundryMD canceled the one I originally shared. I have now replaced it with a working one 🙂
