Bio Complete 3

About 70% of your immune system resides in your gut.1 So taking care of your gut is absolutely key for your overall health. Bio Complete 3 helps support a healthy gut lining with prebiotics, probiotics, and post-biotics… so you can keep the good stuff in your gut where it belongs, and support a healthy, robust immune system. 

With Bio Complete 3 by your side, you can look forward to noticeable results like:

  • Excess weight — especially belly fat — finally becoming easier to lose
  • Fatigue being replaced by an ABUNDANCE of youthful energy
  • Digestive issues improving dramatically, or vanishing altogether
  • Cravings for unhealthy foods feeling like a distant memory
  • Manufactured in USA / 90-Day Money Back Guarantee / GMP Certified Facility

What’s in Bio Complete 3?

Product Description

I designed this unique 3-pronged blend of probiotics, prebiotics, and postbiotics to work together to give your gut a major boost. And once these specialized compounds get to work in your body, don’t be surprised to see your digestion greatly improve… along with your energy levels, weight, and overall health.
Bio Complete 3 can help you enjoy:

  • A slimmer waistline
  • Smoother digestion
  • Easier, more regular bathroom visits
  • Reduced cravings for unhealthy “junk foods”
  • And even more energy

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


What Are The Main Ingredients In Gundry MD Bio Complete 3?

These are the main ingredients in Bio Complete 3:

  • Tributyrin (as CoreBiome™)
  • Sunfiber®
  • Bacillus Coagulans (ProDURA®)

How safe is Gundry MD Bio Complete 3?

Gundry MD Bio Complete 3 contains only safe, all-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 safeguarding 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 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 alleviate symptoms of “leaky gut,” like low energy and cravings for unhealthy food)

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 money, hassle-free… guaranteed.

You can read reviews from Bio Complete 3 lovers below… and you can read all reviews about Gundry MD here.

When can I expect results?

Most users report feeling noticeably smoother digestion, less cravings, along with an increase in energy, vitality, and muscle strength on their first day of use… usually within the first few hours. However, the most dramatic results were reported after consistent use over the course of 4 weeks and beyond. Please use as directed.

Can I buy Bio Complete 3 anywhere else?

  1. Jennifer

    5 out of 5 Positive and palpable changes!


    My system is so incredibly sensitive to literally everything. I have tried other probiotics which had caused skin or stomach issues. Bio Complete 3 is different. Results manifested around the 1.5 month mark: 1) My BMs became awesomely predictable (2x/day), 2) I had more energy–no more slogging up a flight of stairs, 3) Far less bloat meant a trimmer midsection which had plagued me since my mid-40s, and 4) 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!

    5 out of 5 I was skeptical to try...I am amazed at the results!

    Ashley Thompson

    Everything it says can happen, has happened for me – and very quickly. I noticed less bloating, and regularity within the first 2 days. I crave sweets, but that has disappeared in the past week. No more indigestion and discomfort after meals. I have never experienced this much energy in my life. I start my day at 5 am, and work a fairly physical job. Normally by 4 or 5 pm – I don’t have much left in the tank. Not the case any longer! This has absolutely changed my life!

    Bio Complete is a good product because your confidence can be assured with the knowledge that the bases are covered when it comes to your body’s needs in the digestive area. It’s nice to know when you don’t have to take three separate supplements to cover the issues with life’s complicated system in the digestive arena. It’s all working for you daily with this product.

    While I saw benefit from using the Total Restore, I decided to try Bio Complete 3. I was surprised to get immediate benefit. Regularity and feeling lighter have become the norm which was not the case previously. I feel I have discovered a positive step with Bio Complete towards great gut health that even the best diet alone might not achieve. Its great to find a product that is essential to feeling good.

    I have just started using Bio Complete 3 and am experimenting with a diet. I ordered this because I am aware of the importance of probiotics and suspect that I have been deficient. I discovered that a friend has been taking it and has great confidence in Dr. Gundry. I am already enjoying some relief in the absence of stimulant laxatives.

    Helps greatly in reducing sugar cravings and seems to work symbiotically with your other products. I have been taking four each morning so I’m glad that I returned to the site to discover the recommendation to split the dosage am/pm. This should be included on the label. My belly fat has literally melted away in a matter of months.

    5 out of 5 Such A Great Product


    I had used it before, then ran out and didn’t re-order. Have been using various other Dr. Gundry products and like them all… I just can’t help it. Feel so good about them! I was noticing with a great deal of extra stress going on in my life that my stomach was a bit out of sorts. Decided to add back the Bio Complete 3… took about 3 days for me to start feeling much better and more calm, especially my stomach. So, here you have it. These are the best products I’ve ever used. Try some of the other ones too!

    5 out of 5 Working , even better with Vital Reds

    Brenda Williams

    I have been taking the Bio Complete 3 for several weeks now, feeling a positive difference. Few days ago, I started taking the Bio Complete 3 in the mornings with my breakfast as well as drinking the Vital Reds. I feel this has greatly improved the impact on my gut since Vital Reds also contains Probiotics. I do not buy juices, so the Vital Reds does make a great juice drink and knowing it is working with my Bio Complete 3. I can submit another review on both products when I am further into the time frame of using both products. I do feel MUCH better.

    5 out of 5 I believe in Bio Complete 3

    Brenda Stevenson

    After using this product for three weeks, I have definitely noticed some weight loss around my stomach, better consistent bowel movements and more energy. I had reached a plateau In my weight loss plan and just couldn’t loose any more weight. Fasting was not doing the trick either. So I decided to give this product a try and am thrilled with my results. I have lost five pounds in three weeks and still find it hard to believe! I am now increasing my weight bearing exercises since I do seem to have better energy, and now I’m also building muscle and better bone density I hope.
