The main ingredients in Bio Complete 3 are:

  • Tributyrin (as CoreBiome™)

  • Microcrystalline Cellulose
  • Hydroxypropyl Methylcellulose

Is Gundry MD Bio Complete 3 Quality Checked?

Gundry MD Bio Complete 3 contains only pure and natural 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 program.

How do I use Bio Complete 3?†*

Simply take two small capsules twice per day, preferably before a meal. Bio Complete 3 has been formulated to be ultra-fast absorbing — so it can go right to work in your gut — resulting in a boost in energy and health you can truly feel.

It’s important to take your Bio Complete 3 every day on a consistent basis. I take mine every morning before breakfast and again before dinner. This way, my gut is protected 24/7.

How does Gundry MD Bio Complete 3 work?†*

Bio Complete 3 works to support easier digestion, better weight management, more energy, less unhealthy cravings, and improved muscle strength by using what I call the “3-Pronged Defense” to gut health:

  1. Boost your probiotic levels, so you have an abundance of good gut bacteria
  2. Boost your prebiotic levels, so your good gut bacteria have the proper fuel to thrive
  3. Boost butyrate (a.k.a. postbiotic) levels, so you can achieve an “ironclad” gut lining (and help combat issues of “leaky gut,” like low energy and cravings for unhealthy food)

*Every individual is unique. As such, your results may vary.

What if it doesn’t work for me? Is there a guarantee?†

As a physician, I know that individual bodies can react differently to the very same compounds. Even though everyone can benefit from the powerful probiotics, prebiotics, and butyrate — known in the medical community as a “postbiotic” — in this formula, I’m aware that results can vary. So, if you’re unsatisfied with this product for any reason whatsoever after a full 90 days of use, I’ll return your purchase price, hassle-free… guaranteed.

When can I expect results?†*

Most users report feeling noticeably smoother digestion, less cravings, along with an increase in energy, vitality, and muscle strength in their first week of use. However, the most dramatic results were reported after consistent use over the course of 4 weeks and beyond. Please use as directed. Want to know what other people are saying about BioComplete 3?

    5 out of 5 Bio Complete 3

    Shelley Roy

    I am very happy that I decided to try this product. I was take Vital Reds and really liked it, however , reading about Bio Complete 3 I thought it might be better for me. I have been enjoying a happier tummy, as well as, regular bowel movements. Thank you Dr. Gundry for caring about our health and for developing such great products .❤️❤️❤️

  2. Susan

    5 out of 5 Very effective


    I have tried a number of probiotics and prebiotics. It was very inconvenient taking so many plus other supplements. Now I take only Bio Complete 3. I have taken it for six months and don’t plan on ever stopping.

    5 out of 5 Better than I thought

    Randy Lewis

    Definitely cleared up my bowel issues, this and being more aware what goes in my mouth. I am also using the pro plant shake and MCI wellness and my mind seems to be clearing up and I’m remembering things a little better. Waiting to get through the placebo mental phase but so far so good!

  4. Erin

    5 out of 5 Working Great So Far


    I’ve tried a number of probiotics over the years with mixed results. Over the last month that I have been using Bio Complete 3, I’ve really found it to be great. I am more regular and generally feel in better gut health. I look forward to continuing to use for longer term results and will update my review then.

    5 out of 5 Awesome product!

    Tina Chambers, RN

    Thank you Dr Gundry! I don’t know where my overall health would be if I hadn’t discovered your products! I’m an OR nurse, I’m so impressed and thankful you discovered and taught me the importance of “gut health” I remember years ago listening to your videos and thinking “he makes sense, I think he’s on to something” …Few months back I decided to start back on my total restore, started feeling better but when I added bio complete 3, it went to another level, my aches and pains are gone, my brain fog is clearing and I can’t begin to tell you how good I feel. Oh, did I mention I was addicted to mini Dr Peppers, sour candy and lemon cake? All desires for sweets —a thing of the past, I’m not even tempted by it and anyone who’s ever been addicted to sugar knows how amazing that is!!! I feel like a different person! Every product we’ve tried is awesome! My husband loves the circulation, it eliminates his leg cramps. I believe in Dr Gundrys products so much! I just ordered 9 more bottles of restore and 6 bottles of lectin shield, I’m putting my whole family on it. Dr Gundry offers deals, my advice is to take advantage of them, you can’t afford not to. My coworkers are noticing the change and everyone’s ordering it! ( forgot to mention how great my skin is looking!!!) Unfortunately, our culture treats symptoms and not the problem, there’s nothing more important than gut health for your overall health, so if you’re reading this and you’re on the fence, go for it, you won’t be sorry!!! Trust Dr Gundry’s products, he is a brilliant cardiac (heart) surgeon that turned his career to gut health – it’s just that important!!!!

    4 out of 5 Noticed a Difference

    April Hendricks

    I’m pretty impressed so far. Definitely helped with bloating and regularity. Seem to have a little more energy too, but not sure. It’s expensive, but I’ll keep trying it as long as I see these benefits.

    More energy for my weight loss program

  9. Sasha Priest

    5 out of 5 It makes sense and IT WORKS!!!

    Sasha Priest

    I have been taking the suggested amount, 4 capsules daily for about 3 weeks and my cramping, bloating and discomfort have subsided. I was very reluctant to try this but I haven’t felt this good, no belly/gut pain, for about 10 years. I am hoping to see a reduction in my sugar cravings and then a reduction in my waistline! I am so glad I subscribed for monthly deliveries from the start. I won on this gamble.
