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

- I've seen 'leaky gut' products advertised… how is Gundry MD Bio Complete 3 different?
Before I developed this formula, I looked at the other products out there. And I saw huge problems with every one of them… so much so, I refused to recommend any of them. Here's why…
First, most 'leaky gut' products have added sugars or artificial sweeteners. Both are terrible for your body, and they're also highly addictive. Bio Complete 3 has no sugar or artificial sweeteners whatsoever.
Second, many other leaky gut products contain LECTINS — and that's absolutely a no-no for me. We talked earlier about how lectins cause damage all over your body… creating serious problems, including leaky gut. So, Bio Complete 3 has ZERO lectins. It also has no soy, another “toxic health food” I tell everyone to avoid.
Most importantly, though — leaky gut formulas are designed to keep toxins from seeping out into your system. Bio Complete 3 also does this — but it does SO much more, too.
Bio Complete 3 utilizes powerful butyrate so you can build a strong, healthy gut lining… which means your prebiotics and probiotics cannot “slip” through the holes in your gut. When your probiotics, prebiotics, and postbiotics are all safe and secure in your gut… THAT'S when they can do their best work.
So, not only does it keep the toxins from leaking into your system… it keeps the GOOD stuff, right where it belongs. That means YOU get to experience a supercharge in energy, an incredible 'slimming effect,' even better bowel movements, and amazing mental clarity.
It also means any other Gundry MD formula you're currently taking will be supercharged as well. Because when those nutrients and ingredients are “locked in” to your gut, it allows your body to use them much more effectively.
Plus, the big difference between Bio Complete 3 and other digestive health formulas is that I chose the ingredients for this formula based on clinical results.
Look, I'm a surgeon with 30 plus years experience and a published medical nutrition researcher, so I brought that expertise to the table. This formula gets real results because it's got proven ingredients at the right dosage.
Also, Bio Complete 3 is not just a gut health blend at all. It's really a 3-in-1 formula that can help boost energy, slim your waist, and solve leaky gut like nothing else can. It's a complete package with the right stuff that works.
- Are there any side effects?
Gundry MD Bio Complete 3 contains only 100% pure, quality ingredients. The content of every batch is tested at my own facility, and then tested again for quality and purity at an outside, 3rd-party laboratory.
And again, my formula contains none of the toxic elements you'll find in lots of other so-called “health products.” Gundry MD Bio Complete 3 is sugar-free, artificial sweetener-free, lectin-free, soy-free, and dairy-free.
As a physician, I'm putting my reputation on the line with this product — so you can be sure I go to great lengths to make sure every bottle is absolutely safe.
I made a pledge when I developed the Gundry MD line: I will never sell any product I wouldn't personally recommend to a loved one.
But, of course, as a physician I know that no supplement works for everyone. There's always a very small segment of the population who may be allergic or who can't tolerate certain ingredients in supplements.
So consult your doctor before starting any new dietary supplement. And if you want to return it for any reason at all, simply contact our US-based customer support team for an immediate refund.
