Bio Complete 3

Bio Complete 3 is the complete gut health package. It contains a uniquely potent blend of premium probiotics, prebiotics, and a revolutionary new compound called postbiotics. This formula has been shown to improve your digestion, boost your metabolism, reduce cravings, and help you to enjoy the energy levels of someone years younger.

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.


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.

    5 out of 5 Best Gut supplement available


    This is hands down, without a doubt the best gut support supplement I have ever taken. I have been a regular user of Lectin Shield for a number of years which I rate highly. But, I had tended to use Lectin Shield on “as needed” basis taken before a meal with questionable ingredients. I take Bio Complete 3 daily. Frankly, it has been life changing. Any residual gut issues I still had after following Dr Gundry’s diet advice for over 4 years now have evaporated. I take it about one hour after getting up and on an empty stomach. No acid reflux, no discomfort and the daily toilet visit is trouble free. My energy levels are like i am back in my 20’s. I crave caffeine much less. Please keep this in stock. Will be taking long term.

    5 out of 5 Life changing product


    I am in my 50’s. I have been suffering from severe fatigue, brain fog, muscle and joint pain. It was to the point where I was in bed more days than I was up. I had gone to several doctors with the same results-sending me to another doctor. I was fed up! I just wanted to feel better. I started researching my symptoms to find the causes and to find a solution. I decided to try Bio Complete 3. Wow! What a life changing product! I noticed gradual improvement starting the first week. After the second week, I was having more “active” days. It was taking me less time to recover after an “active ” day. I have been taking this for 1 month and I have energy, no muscle and joint pain (even when it rains). I am able to do gardening! I am able to work a full day! I am able to take walks and exercise! Life changing.

    5 out of 5 Great Product!

    Cary Swenson

    I’ve been on this for one month and my regularity is substantially increased. I will stay on this product for at least 6 months because it takes time to turn around nutritional deficiencies. Since you can’t always “feel” how a product is working, I want to build up good gut health as I’ve been told about 80% of your immune health is in your gut [..] I trust Dr. Gundry and am willing to give this product a good try.
