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.

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?

Gundry MD products, including Bio Complete 3, are not sold in retail stores and are not available anywhere else. Please click here for more info.

    These are the best prebiotic and probiotics I have used. I personally felt the difference in my digestion immediately and became far more regular which is always my top priority. These seemed to have what I was missing. I will definitely continue to use.

    I love that this product covers “all the bases”! Pre-, Pro-, and Postbiotic all in one easy to take form. I am not good about sticking to much more of a routine than just AM & PM taking of supplements. This product fits into my routine […] and made bathroom trips much more normal!

My digestive system is very pleased, to say the least. I guess my gut buddies are rewarding the rest of me by giving me more spunk & vitality throughout each day to stay on top of living my youthful life. Thank you for this excellent product!!!

    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.

    Debra Smith

    Only have had it for three weeks, but I don’t have stomach acid at night when I want to sleep. I am regular now and I have been able to cut down on sweets I do not crave them. I have six months worth of tablets I hope to feel like a new person then. I also use Lectin Shield. I’ll be 70 next year.

    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.

    I was very skeptical and wasn’t expecting the results that were promoted in Dr. Gundry’s video. Since i have been working from home for the last few weeks, I feel more energized than I thought I would, not snacking and feeling full most days of the week. I need to do better with watching sugar intake (it’s in everything!!!) and trying to keep in natural. I do feel better from a gut health standpoint and have noticed less bloating. I am 1/2 way through my 1st bottle and it’s going great so far.

    I take BC3 along with total restore. Have been on for a month and the biggest difference is the amazing sleep, amazing mornings, combined with amazing natural energy. This truly works, I feel great. I have since purchased vital reds, Calm Probiotic Cream, untox, and botanical cleanser because Dr Gundry gives such great deals often. I always buy in bulk, and try the offering because I know how much he cares and I can feel my health getting better, you can’t fake that feeling of happiness. Thank you !
